CAUTION means an alert that calls attention to important information that if not understood or followed can result in data loss, data corruption, or damage to hardware or software.

General safety recommendations

· Make sure the ground is dry and flat and anti-slip measures are in place.

· Keep the chassis and installation tools away from walk areas.

· Make sure the installation site is reliably grounded, and lightning protection and ESD-prevention are provided.

· Only trained and qualified personnel are allowed to install or service the router.

· Keep accessories, installation tools, and documentation safe.

· Avoid bodily injury. Do not touch any power plug when it is connected.

· Clean up the packaging materials after installation to avoid fire hazard.

Electricity

· Locate the emergency power-off switch in the room before installation. Shut the power off at once in case accident occurs.

· Make sure the router has been correctly grounded.

· Use an uninterrupted power supply (UPS).

· If there are two power inputs, disconnect the two power inputs to power off the router.

· Do not work alone when the router has power.

· Always verify that the power has been disconnected.

Laser safety

The H3C SR6602-X routers are Class 1 laser devices.

WARNING!

· Do not stare into any fiber port when the router has power. The laser light emitted from the optical fiber may hurt your eyes.

· Use a fiber test equipment, rather than a microscope or magnifier to observe an operating fiber or port when you test link connectivity or system parameters.

Router moving

When you move an SR6602-X router, follow these guidelines:

· Move and unpack the router carefully to avoid router damage.

· Use a safety hand truck when you move a heavy device or multiple devices.

· Before you move the router, remove all the cables, USB devices, mounting brackets, and cable management brackets.

· If the router needs to be moved over a long distance, remove all the field-replaceable units (FRUs), such as power modules, fan trays, and interface modules, and package them separately, and install the filler panels supplied with router.

· If the router needs to be moved over a short distance, make sure all the FRUs are securely seated in slot and the screws are fastened.

· When you move or lift the router chassis, support the bottom of the chassis, rather than holding any FRU. Make sure the accessories of the router are not lost or damaged during router moving.

Examining the installation site

Weight support

Evaluate the floor loading as compared to the actual weight of the router and its accessories (such as rack and power modules), and make sure the floor can support the weight of the rack and the router chassis. For more information, see “Appendix A Chassis views and technical specifications.”

Temperature and humidity

Maintain appropriate temperature and humidity in the equipment room.

· Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.

· Lasting low relative humidity can cause washer contraction and ESD and bring problems including loose captive screws and circuit failure.

· High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the router.

For the temperature and humidity requirements of the router, see Table 1.

Table 1 Temperature requirements

Item	Temperature
Operating temperature	0°C to 45°C (32°F to 113°F)
Storage temperature	–40°C to +70°C (–40°F to +158°F)

Table 2 Humidity requirements

Item	Relative humidity
Operating humidity	5%RH to 95%RH

Operating altitude	–60 m (–196.85 ft) to 4 km (2.49 miles)
Storage altitude	–60 m (–196.85 ft) to 4.5 km(2.8 miles)

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure.

Table 4 Dust concentration limit in the equipment room

Substance	Concentration limit (particles/cu m)

Cooling system

The SR6602-X routers use left to right airflow for heat dissipation.

Figure 1 Airflow (SR6602-X1)

· Make sure there is enough space (greater than 10 cm (3.94 in)) around the air intake and outlet vents on the router for good ventilation.

· Make sure the installation site has a good cooling system.

ESD prevention

CAUTION:

· Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range of 1 to 10 megohm (Mohm) between human body and the ground.

· The SR6602-X does not provide any ESD wrist strap. Prepare it yourself.

To prevent electrostatic discharge (ESD), note the following guidelines:

· Make sure the router and rack are well grounded.

· An anti-static floor is installed and well grounded.

· Maintain the humidity and temperature at a proper level in the equipment room. For more information, see “Temperature and humidity.”

· Always wear an ESD wrist strap and ESD cloth when touching a circuit board, interface module, or transceiver module.

· Place the removed memory module, CF card, FIP, HIM, or MIM on an antistatic workbench, with the face upward, or put it into an antistatic bag.

· Touch only the edges, instead of electronic components when observing or moving a removed memory module, CF card, HIM, or MIM.

To use the ESD wrist strap, perform the following steps:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to keep good contact with the skin.

3. Attach the ESD wrist strap to the alligator clips.

4. Attach the alligator clips to the rack post.

5. Make sure the rack is well grounded.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:

· A conduction pattern of capacitance coupling.

· Inductance coupling.

· Electromagnetic wave radiation.

· Common impedance (including the grounding system) coupling.

To prevent EMI, use the following guidelines:

· If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.

· Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.

· Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Lightning protection

To protect the router from lightning better, do as follows:

· Make sure the chassis is well grounded.

· Make sure the grounding terminal of the AC power receptacle is well grounded.

Space

For easy installation and maintenance, follow these space requirements:

· Reserve a minimum of 1 m (3.28 ft) of clearance between the rack and walls or other devices.

· For heat dissipation, make sure the headroom in the equipment room is no less than 3 m (9.84 ft).

· Make sure the rack has enough space to accommodate the switch. See Table 6 for rack requirements. For more information about chassis dimensions, see "Appendix A Chassis views and technical specifications."

Power supply

Perform the following steps to satisfy the power supply requirements of the SR6602-X routers:

1. Calculate the system power consumption.

The system power consumption of the SR6602-X routers depends on the number and type of interface modules, and fan tray power consumption. For the power consumption of the router, see “Appendix A Chassis views and technical specifications.”

2. Select power modules according to the system power consumption.

To ensure normal operation of the router, make sure the maximum output power of the power modules is greater than the system power consumption of the router. After determining the system power consumption, you can select power modules as needed. For power module specifications, see “Appendix A Chassis views and technical specifications.”

3. Verify that the power source on the installation site satisfies the power input of the power modules.

Make sure the power source of the installation site is steady and can satisfy the input requirements of the power modules and parameters such as rated voltage.

Figure 21 Connecting the AUX port to a modem

Connecting an Ethernet cable

Overview

10/100 Mbps Ethernet uses category-5 twisted pair cables, while 1000 Mbps Ethernet uses category-5 enhanced or category-6 twisted pair cables. Twisted pair cables include straight-through cables and crossover cables.

Category-5 cables provide a transmission frequency of 100 MHz for voice and data transmission; they are mainly used in 100Base-T and 10Base-T networks. Category-5 cables are common Ethernet cables, which can also be used to transmit 1000 Mbps Ethernet data.

Category-5 enhanced cables feature low attenuation and crosstalk, providing higher attenuation to crosstalk ratio (ACR), less delay error and higher performance than category-5 cables. Category-5 enhanced cables are mainly used in 1000 Mbps Ethernet networks.

Category-6 cables provide a transmission frequency of 1 MHz to 250 MHz, and improve the performance on crosstalk and return loss. A fine better return loss performance is extremely important for new-generation full-duplex high-speed networks. Category-6 cables have sufficient power sum ACR (PS-ACR) when working at 200 MHz. They provide a bandwidth two times than that of category-5 enhanced cables, thus featuring a higher transmission performance. Therefore, category-6 cables are suitable for applications requiring a transmission speed of more than 1 Gbps.

The 10/100 Mbps Ethernet uses two pairs of cables, orange/white, orange, green/white and green cables, to transmit and receive data, while the 1000 Mbps Ethernet uses four pairs of cables to transmit and receive data.

An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure 22 shows the pinouts of an RJ-45 connector.

Figure 22 RJ-45 connector pinout

EIA/TIA cabling specifications define two standards, 568A and 568B, for cable pinouts.

· Standard 568A—Pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown solid.

· Standard 568B—Pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown solid.

Ethernet twisted pair cables can be classified into straight-through and crossover cables based on their pinouts

For the pinouts of the twisted pair cables, see the following tables. (A and B represent the two ends of a cable, respectively.)

Table 8 Straight-through cable pinouts

Pinout No.	A	B
1	Orange/white	Orange/white
2	Orange	Orange
3	Green/white	Green/white
4	Blue	Blue
5	Blue/white	Blue/white
6	Green	Green
7	Brown/white	Brown/white
8	Brown	Brown

7	Brown/white	Brown/white
8	Brown	Brown

NOTE:

Strictly follow the pinouts in the above tables when identifying or making the two types of Ethernet cables; otherwise, the communication quality may be affected.

Making an Ethernet cable

1. Cut the cable to a proper length with the crimping pliers.

2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector.

3. Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring specifications.

4. Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the RJ-45 end and in the correct order.

5. Crimp the RJ-45 connector with the crimping pliers until you hear a click.

6. Use a cable tester to verify the proper connectivity of the cable.

Connecting an Ethernet cable

1. Plug one end of an Ethernet twisted pair cable into the copper Ethernet port (RJ-45 port) to be connected on the router and the other end of the cable into the Ethernet port of the peer device. The 10/100/1000Base-T copper ports of the router support MDI/MDI-X auto-sensing. They are connected to the network through category-5 or above twisted pairs that are equipped with RJ-45 connectors.

2. Check the status LED of the Ethernet ports. For more information about the LED status, see “Appendix B LEDs.”

Connecting a fiber cable

Transceiver module overview

When you use a fiber port, you need an SFP, XFP, or SFP+ transceiver module and a fiber cable with an LC connector.

· SFP transceiver module—Applicable to 100/1000 Mbps Ethernet fiber ports and SFP ports on some HIMs.

· XFP transceiver module—Applicable to XFP ports on the HIM-1EXP.

· SFP+ transceiver module—Applicable to GE SFP+ ports on the SR6602-X2.

Figure 23 SFP transceiver module

Figure 24 XFP transceiver module

Figure 25 SFP+ transceiver module

Fiber cable overview

You can use an optical fiber to connect a fiber Ethernet port or 10 Gbps Ethernet port. In addition, an optical fiber can connect fiber ports on interface modules.

Optical fibers feature low loss and long transmission distance.

Optical fibers can be classified into single mode fibers and multi-mode fibers. A single mode fiber carries only a single ray of light; a multi-mode fiber carries multiple modes of lights.

Table 10 Characteristics of single mode and multi-mode optical fibers

Item	Single mode fiber	Multi-mode fiber
Core	Small core (10 micrometers or less)	Larger core than single mode fiber (50 micrometers, 62.5 micrometers or greater)
Dispersion	Less dispersion	Allows greater dispersion and therefore, signal loss exists.
Light source and transmission distance	Users lasers as the light source often within campus backbones for distance of several thousand meters	Uses LEDs as the light source often within LANs or distances of a couple hundred meters within a campus network

Table 11 Allowed maximum tensile force and crush load

Period of force	Tensile load (N)	Crush load (N/mm)
Short period	150	500
Long term	80	100

Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient. There are multiple types of fiber connectors. Figure 26 shows an LC connector.

Figure 26 Appearance of an LC connector

光纤连接器.wmf

NOTE:

· The SR6602-X supports LC fiber cables only.

· Some cards of the H3C SR6602-X router provide shielded covers for the fiber ports (such as SFP ports). Before using such fiber ports, remove the shielded covers. Keep the shielded covers properly. When the fiber ports are not in use, install the shielded covers.

· Fiber connectors are fitted with dust caps. Keep the dust caps properly when the fiber connectors are in use. Install dust caps when the fiber connectors are not in use to avoid damage to their end face. Replace the dust cap if it is loose or polluted.

· Before connecting an optical fiber, use dust free paper and absolute alcohol to clean the end face of the two fiber connectors. You can brush the end faces only in one direction.

· After a fiber is installed well, the bend radius must be not less than 10 cm (3.94 in).

· If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted surface (the filleting radius must be not less than 2 mm, or 0.08 in). When passing through a metallic board hole or bending along the acute side of mechanical parts, the fiber must wear jackets or cushions.

· Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the plug may be damaged or the fiber may be broken. Never pull, press or extrude the fiber fiercely. For the allowed maximum tensile load and crush load, see Table 11.

Connecting a fiber cable

WARNING!

Do not stare into any fiber port when you connect an optical fiber. The laser light emitted from the optical fiber may hurt your eyes.

To connect a fiber cable:

1. Remove the dust plug from a fiber port of the router.

2. Install the transceiver module

3. Identify the Rx and Tx ports. Plug the LC connector at one end of one fiber cable into the Rx port of the router and the LC connector at the other end into the Tx port of the peer device. Plug the LC connector at one end of another fiber cable into the Tx port of the router and the LC connector at the other end to the Rx port of the peer device.

4. View the LINK LED after connection.

? If the LED is on, the optical fiber link is present.

? If the LED is off, no link is present. This may be because the TX and Rx port of the optical fiber are not connected correctly. In this case, connect the optical fiber again.

Displaying transceiver module information

To identify transceiver modules, you can use the following command to view the key parameters of the transceiver modules, including transceiver module type, connector type, central wavelength of the laser sent, transmission distance, and vendor name or name of the vendor who customizes the transceiver modules.

To display transceiver module information:

Purpose	Command	Remarks
Display key parameters of the transceiver module in a specified interface	display transceiver interface [ interface-type interface-number ]	Available for all transceiver modules

Displaying the alarming information or fault detection parameters for a transceiver module

The system outputs alarm information for you to locate and troubleshoot faults of transceiver modules. For the H3C-customized transceiver modules, the system can also monitor the key parameters, such as temperature, voltage, laser bias current, TX power, and RX power. When these parameters are abnormal, you can take corresponding measures to prevent transceiver module faults.

To display the alarming information or fault detection parameters of a transceiver module:

Purpose	Command	Remarks
Display the current alarm information of the transceiver module in a specified interface	display transceiver alarm interface [ interface-type interface-number ]	Available for all transceiver modules

NOTE:

For more information about the transceiver module displaying commands, see H3C SR6600 Router Series Command References.

Solving system faults

When the system detects faults (such as system instruction faults, invalid addresses, data overflow, null pointers, and division by zero operations) during the operation of the active MPU or standby MPU, you can solve the problem in one of the following methods:

· Reboot—Rebooting the failed MPU so that the MPU restores to normal operational status.

· Maintain—Maintaining the current status of the failed MPU so that the system does not take any restoration measures. Some software faults are hard to reproduce, and the printed information will be lost after the router reboots. In this case, you can maintain the current status of the router, facilitating fault location.

To solve system faults:

Step	Command	Remarks
1. Enter system view	system-view	N/A
2. (Optional)Specify the system fault solving method for the active MPU and standby MPU	system-failure { maintain \| reboot }	The default method is reboot.

Viewing the system fault solving method

Use the display system-failure command to display the system fault solving method.

<Sysname> display system-failure

System failure handling method: reboot

Saving the current configuration of the router

You can save the current configuration of the router in one of the following methods:

· Fast saving—Executing the save command without the safely keyword. This mode saves the file more quickly but is likely to lose the existing configuration file if the router reboots or the power fails during the process. The fast saving mode is suitable for environments where the power supply is stable.

· Safe saving—Executing the save command with the safely keyword. The mode saves the file more slowly but can retain the configuration file in the router even if the router reboots or the power fails during the process. The safe saving mode is preferred in environments where a stable power supply is unavailable or remote maintenance is involved.

Table 20 To save the current configuration of the router:

Purpose

Command

Remarks

Save the current configuration to the specified file, but the configuration file will not be set as the file for the next startup

save file-url

Use either command

Available in any view

Save the current configuration to the root directory of the storage medium of the active or standby MPU and specify the file as the startup configuration file that will be used at the next system startup

save [ safely ]

NOTE:

· The configuration file must be with extension .cfg.

· During the execution of the save command, the startup configuration file to be used at the next system startup may be lost if the router reboots or the power supply fails. In this case, the router will boot with the factory defaults, and after the router reboots, you need to re-specify a startup configuration file for the next system startup.

Rebooting the router

When upgrading and maintaining the startup configuration file or configuration file for the router, you need to reboot the router. To reboot a router, use one of the following methods:

· Use the reboot command to reboot a router.

· Enable the scheduled reboot function at the CLI. You can set a time at which the router can automatically reboot, or set a delay so that the router can automatically reboot within the delay.

· Power on the router after powering it off, which is also called hard reboot or cold start. Powering off a running router causes data loss and hardware damages, and therefore is not recommended.

· Use the RESET button.

To reboot the router immediately:

Purpose

Command

Remarks

Reboot the router immediately

Available in user view

Enable the scheduled reboot function and specify a reboot waiting time

schedule reboot delay { hh:mm | mm }

CAUTION:

· If the main system software image file does not exist, do not use the reboot command to reboot the router. Specify the main system software image file first, and then reboot the router.

· The precision of the rebooting timer is 1 minute. One minute before the rebooting time, the router prompts “REBOOT IN ONE MINUTE” and reboots in one minute.

· If you are performing file operations when the router is to be rebooted, the system does not execute the reboot command for security.

· The router does not save the current configuration when you press the RESET button to reboot the router.

· To avoid system damage, do not press the RESET button repeatedly when the RUN LED is fast flashing.

If the configuration terminal displays nothing when the router is powered on, To troubleshoot the failure:

1. Check the following items.

? The power supply system works properly.

? The console cable is properly connected.

2. If no problem is found, check the following reasons that may apply:

? The console cable is connected to an incorrect serial port (the serial port in use is not the one set on the terminal).

? The properties of the terminal are incorrect. You must configure the console terminal as follows: set Bits per second to 9600, Data bits to 8, Parity to None, Stop bits to 1, Flow control to None, and Terminal Emulation to VT100.

? The console cable fails.

3. If the cause cannot be located in the steps above and the problem persists, contact your local sales agent.

Garbled terminal display

If terminal display is garbled, To solve this problem:

1. Make sure the Data bits field is set to 8 for the console terminal. If the Data bits field is set to 5 or 6, the console terminal will display garbled characters.

2. Make sure the Bits per second field is set to 9600 kbps. An incorrect bits per second may also cause the configuration terminal to display garbled characters.

No response from the serial port

If the serial port gives no response, verify that the serial port settings are correct.

NOTE:

For more information about the serial port settings, see “Setting terminal parameters.”

Password loss

CAUTION:

Dealing with console login password loss and user privilege level password loss from BootWare menus is disruptive.

How to deal with console login password loss and user privilege level password loss depends on the state of password recovery capability (see Figure 65). Password recovery capability controls console user access to the device configuration and SDRAM from BootWare menus.

· If password recovery capability is enabled, a console user can access the device configuration without authentication and configure new passwords.

· If password recovery capability is disabled, a console user must restore the factory-default configuration before configuring new passwords. Restoring the factory-default configuration deletes the main and backup next-startup configuration files.

To enhance system security, disable password recovery capability.

Appendix C Cable management

When an SR6602-X router is mounted in a 19-inch standard rack, the interface cables are routed through the cable management brackets, bound at cabling racks on chassis sides, and then routed up or down, depending on the available equipment room condition. The power cables run along the two sides of the chassis and out of the chassis either from the chassis top or the raised floor depending on the equipment room conditions (power distribution cabinet, lightning protection box, and connector strip, etc.) of the exchange office.

General cabling requirements

Minimum curvature radius of cables

· The curvature radius of a fixed power cable, communication cable, or ribbon cable should be at least five times the cable’s outer diameter. If the cable is frequently bent, plugged, and unplugged, the curvature radius should be at least seven times the cable’s outer diameter.

· The curvature radius of an ordinary fixed coaxial cable should be at least seven times of the cable’s outer diameter. If the coaxial cable is frequently bent, plugged, and unplugged, the curvature radius should be at least 10 times the cable’s outer diameter.

· The curvature radius of a high-speed cable (for example, SFP+ cable) should be at least five times of the cable’s outer diameter. If the coaxial cable is frequently bent, plugged and unplugged, the curvature radius should be at least 10 times the cable’s outer diameter.

Minimum curvature radius of fibers

· When the fiber is wrapped up around the cabling plate, the diameter of the cabling plate should be at least 25 times the fiber’s diameter.

· When the fiber is being moved, the curvature radius of the fiber should be at least 20 times the fiber’s diameter.

· When the fiber is fixed, the curvature radius of the fiber should be at least 10 times the fiber’s diameter.

NOTE:

The fiber’s diameter refers to the outer diameter of the fiber jacket. Typically, the diameter of a single-core fiber is 0.9 mm (0.04 in), 2.0 mm (0.08 in), or 3.0 mm (0.12 in).

Labeling cables

Label cables before you route or bundle them. Labels are typically affixed 20 mm (0.79 in) to cable plugs.

Cable management guidelines

When you route and bundle up cables, follow these guidelines:

· Bind and route the cables neatly inside the rack, and make sure the cables are not kinked or bent.

Figure 80 Correct and incorrect cable binding

Snap1

· The cable bend radius at connectors must be at least 5 times the cable diameter, and must be at least twice the cable diameter away from the connectors.

· Route different types of cables (for example, power cables, and signal cables) separately. If they are close to one another, cross them over one another. If you route them in parallel, make sure the space between a power cable bundle and a signal cable bundle is at least 30 mm (1.18 in).

· The cable management brackets and cable routing slots, inside or outside the rack, are smooth and have no sharp edges or tips.

· When you route cables through sharp sheet metal penetration points or along sharp edges of mechanical parts, use bushings or take any other action to protect the cables from being cut or abraded. The sheet metal penetration points must be smooth and fully rounded.

· Use the correct ties to bind the cables. Do not bind cables with joined ties. The following types of ties are available: 100 × 2.5 mm (3.94 × 0.10 in), 150 × 3.6 mm (5.91 × 0.14 in), 300 × 3.6 mm (11.81 × 0.14 in), 530 × 9 mm (20.87 × 0.35 in), and 580 × 13 mm (22.83 × 0.51 in).

· After binding the cables, cut the excess from the ties, leaving no sharp or angular tips. See Figure 81.

Figure 81 Cutting the cable ties

电缆捆扎示范2

· When you bend cables, bind cables as shown in Figure 82. To avoid cable core break due to excessive stress, do not tie up the cables in the bending area.

Figure 82 Binding the cables

电缆捆扎示范3

· Route, bind, and attach excess cables for easy, safe maintenance activities and proper operations.

· Do not tie the power cables to the slide rails.

· When you connect a cable to an articulated part, for example, when you connect a grounding cable to a cabinet door, leave enough slack in cables and make sure they are not stressed from any movement of the part.

· Cables must be protected at points where they might rub or come in contact with sharp edges or heated areas. Use high temperature cables near heat sources.

· Securely fasten cables and take adequate measures to prevent loose connections.

Figure 83 Securely fasten cables

(1) Flat washer	(2) Spring washer	(3) Nut

· Fasten heavy or rigid power cables at the connectors to relief stress.

· Do not use tapping screws to fasten the connecting terminals.

· Bind together cables that are the same type and routed in the same direction.

Table 46 lists the cable bundling specifications.

Table 46 Cable bundling specifications

Cable bundle diameter (mm)	Space between bundles (mm)
10	80 to 150
10 to 30	150 to 200
30	200 to 300

· Do not tie cables or bundles in a knot.

· The metal parts of the crimped cold-pressed terminal blocks (such as circuit breaker) cannot protrude beyond the blocks.

Cable routing example

Cables on an SR6602-X router can be routed as shown in Figure 84.

Figure 84 Routing cables

Appendix D Arranging slots and numbering interfaces

Slot arrangement

The router provides many types of interfaces, such as console, AUX, GigabitEthernet, serial (synchronous), POS, and E1 ports. This chapter describes how these interfaces are numbered.

Figure 85 Slot arrangement on the SR6602-X1

Figure 86 Slot arrangement on the SR6602-X2

NOTE:

In Figure 85 through Figure 86, the blue numbers represent slot numbers of the SR6602-X routers.

Available slots for FIP-10/FIP-20

Card	SR6602-X1	SR6602-X2
FIP-10	Slot 1	Slot 1
FIP-20	Slot 1	Slot 1

Numbering interfaces

Before installing a HIM/MIM, you must install a FIP. A FIP-20 supports both HIMs and MIMs, while a FIP-10 supports only MIMs.

The interfaces of the router are numbered in the form of interface-type X/Y/Z,

Where,

· interface-type—Type of the interface such as GE port and serial port.

· X—Number of the slot where the FIP resides.

Different HIMs/MIMs on the same FIP have the same slot number X.

· Y—Sub-slot number, the number of the slot where the HIM/MIM resides on the FIP.

Different interfaces on the same HIM/MIM have the same sub-slot number Y.

· Z—Sequence number of the interface on the HIM/MIM.

For each type of interface, the sequence number Z starts from 0 on the HIM/MIM.

Example

A MIM-2GBE module is installed on the FIP-10 in slot 1.

GigabitEthernet interfaces on the MIM-2GBE

1. If the MIM-2GBE is installed in slot 1 of the FIP-10, the GigabitEthernet interfaces are:

? GigabitEthernet 1/1/0

? GigabitEthernet 1/1/1

2. If the MIM-2GBE is installed in slot 2 of the FIP-10, the GigabitEthernet interfaces are:

? GigabitEthernet 1/2/0

? GigabitEthernet 1/2/1
