To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

Safety symbols

When reading this document, note the following symbols:

WARNING means an alert that calls attention to important information that if not understood or followed can result in personal injury.

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.

Electricity safety

· Locate the emergency power-off switch in the room before installation. Shut the power off at once in case accident occurs. Disconnect the power cord of the router if necessary.

· Use an uninterrupted power supply (UPS).

· Do not work alone when the router has power. Do not touch any power plug when it is connected.

· Always make sure the power has been disconnected during installation and replacement.

Laser safety

WARNING!

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

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

The routers are Class 1 laser devices.

When you connect an optical fiber, follow these guidelines:

· Some interface modules on the 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 secure. When the fiber ports are not in use, install the shielded covers.

· Fiber connectors are fitted with dust caps. Keep the dust caps secure 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.

Router moving

CAUTION:

Do not hold the handle of the fan tray or power supply, the handle of the rear cover of the chassis, or the air vents of chassis. Any attempt to carry the router with these parts might cause equipment damage or even bodily injury.

When you move a router, follow these guidelines:

· Lift and put down the chassis slowly and never move suddenly.

· When you move a heavy router or multiple routers, use a pallet jack.

· Before moving the chassis, turn off the power switch and remove all cables, USB devices, and mounting brackets.

· If the router needs to be moved over a long distance, remove all field replacement units (FRUs), such as HIMs/MIMs/MICs, put them separately in anti-static bags, and install the filler panels supplied with router.

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

· Make sure the accessories of the router are not lost or damaged during router moving.

· 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.

ESD prevention

CAUTION:

Make sure the resistance reading between human body and the ground is in the range of 1 to 10 megohms (Mohms).

To prevent electrostatic discharge (ESD), follow these guidelines:

· Make sure the router and the rack are well grounded.

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

· Take dust-proof measures for the equipment room.

· Maintain the humidity and temperature in the acceptable range.

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

· Place the removed CF card or LPU on an antistatic workbench, with the face upward, or put it into an antistatic bag.

· Touch only the edges, instead of electronic components when you observe or move a removed CF card or LPU.

To attach an ESD wrist strap:

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. Insert the ESD plug into the ESD socket.

4. Make sure the rack is well grounded.

Examining the installation site

The routers can only be used indoors. To make sure the router operates correctly and to prolong its service lifetime, the installation site must meet the following requirements:

Weight support

Make sure the floor can support the total weight of the router and accessories (such as the rack and HIMs/MIMs/MICs). For the weight of the router and accessories, see H3C SR6604-X/SR6608-X/SR6616-X Routers Hardware Information and Specifications.

Temperature

If the temperature in the equipment room is too high, too low, or changes dramatically, the router reliability is reduced and its service lifetime is shortened. For long-term, highly available operation of the router, make sure temperature in the equipment room meets the requirements described in Table1-1.

Table1-1 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)

Humidity

Maintain appropriate humidity in your equipment room, as described in Table1-2.

· 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 screws and circuit failure.

Table1-2 Humidity requirements

Item	Humidity
Operating humidity (noncondensing)	10% RH to 95% RH
Storage humidity (noncondensing)	5% RH to 95% RH

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.

Table1-3 Router requirement for cleanliness

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 1.8 × 107 particles/m3

Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases do not exceed the concentration limits as shown in Table1-4.

Table1-4 Corrosive gas concentration limits

Gas	Average concentration (mg/m3)	Maximum concentration (mg/m3)
SO2	0.3	1.0
H2S	0.1	0.5
Cl2	0.1	0.3
HCI	0.1	0.5
HF	0.01	0.03
NH3	1.0	3.0
O3	0.05	0.1
NOX	0.5	1.0

Cooling system

Fan trays of the routers are hot swappable and support automatic fan speed adjustment. To ensure good ventilation, the following requirements must be met:

· Leave a minimum clearance of 10 cm (3.94 in) at the inlet and outlet air vents.

· The installation site has a good cooling system.

The SR6604-X and SR6608-X routers use the same airflow design.

Figure1-2 Airflow through the SR6608-X chassis

Figure1-3 Airflow through the SR6616-X chassis

EMI

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

· Take effective measures to filter interference from the power grid.

· Separate the grounding equipment of the router from the grounding facility and lightning protection facility of the other electrical devices as far as possible.

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

· Use electromagnetic shielding when necessary.

Lightning protection

To protect the router from lightning, perform the following tasks:

· Make sure the grounding cable of the chassis is well grounded. For how to connect the grounding cable, see "Grounding the router."

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

· Install a lightning arrester at the input end of the power supply to enhance the lightning protection capability of the power supply.

· Install a special lightning arrester at the input end of outdoor signal lines (for example, E1 line) to which interface modules of the router are connected to enhance the lightning protection capability.

For how to install lightning protectors and surge protector, see "Connecting the AC power supply to a power strip with lightning protection" and "Installing a surge protector."

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 not less than 3 m (9.84 ft).

· Make sure the rack has enough space to accommodate the router. See Table1-5 for rack requirements. For more information about chassis dimensions, see H3C SR6604-X/SR6608-X/SR6616-X Routers Hardware Information and Specifications.

Installing a lightning protector for a network port

Read the instructions for the lightning protector carefully before you install it.

The lightning protector for a network port is only applicable to a copper Ethernet port.

If part of the network cable of a copper Ethernet port must be routed outdoors, connect a lightning protector to the cable before you plug the cable into the port.

You can install the following port lightning protectors to the router:

Type	Port description	Max. discharge current (8/20μs waveform)	Output voltage
10 Mbps/100 Mbps port lightning protector	Single port	2.5 KA	· Core-core ≤ 15 V · Core-ground ≤ 300 V
1000 Mbps port lightning protector	Single port	3 KA	· Core-core ≤ 15 V · Core-ground ≤ 350 V

Type

Port description

· Core-core ≤ 15 V

· Core-ground ≤ 350 V

Installation procedure

1. Use a double-faced adhesive tape to stick the lightning protector onto the router chassis, and make sure it is as close to the grounding screw of the router as possible.

2. Measure the distance between the protector and the grounding screw of the router, cut the ground wire of the protector as appropriate, and securely tighten the ground wire to the grounding screw of the router.

3. Use the multimeter to measure whether the ground wire of the protector contacts well with the grounding screw of chassis.

4. Insert the outdoor network cable into the protector's IN end, and the cable connected to the router into the OUT end, and examine the indicators on the lightning protector to verify that the connection is correct.

5. Use nylon ties to bundle the cables neatly.

Figure2-18 Installing a lightning protector for a network port

(1) Grounding cable	(2) Lightning protector

Installation precautions

The performance of the port lightning protector might be affected in the following cases:

· The port lightning protector is installed in reverse direction. Connect the IN end to the outdoor network cable and the OUT end to the network port on the router.

· The port lightning protector is not well grounded. After the connection, use the multimeter to confirm that the ground wire for the protector is as short as possible to ensure its good contact with the grounding screw of the router.

· The installed port lighting protectors are not sufficient. If the router has more than one network port connected with other devices through cables outdoor, install a lightning protector for each network port.

Connecting the AC power supply to a power strip with lightning protection

CAUTION:

Make sure the PE terminal of the power socket has been securely grounded.

If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect the AC power cord of the router to the AC power line to protect the router from being damaged by lightning strikes.

You can attach the power strip to the rack, workbench, or wall of equipment room.

After you connect the AC power cord from the router to a socket on the power strip, verify that the green RUN LED on the strip is on and the red LED is off.

If the red LED is on, use a multimeter to check the polarity of the wires in the power socket for wrong connections. If the zero wire (left) and the live wire (right) are correctly connected, check for missing grounding connection.

Figure2-19 Power strip with lightning protection

(1) Operating LED (green)	On means the circuit is operating correctly. Off means the circuit is damaged.
(2) Grounding/pole detection LED (red)	On indicates a wrong wire connection. (The wire is not grounded or the live line and null line are reversely connected.) In this case, you need to check the power supply line.

(6) Multifunctional socket	It is used to connect the power module of the router.

Installing a surge protector

CAUTION:

Ground the surge protector as near as possible. The grounding resistance must be less than 4 ohms. The grounding resistance must be less than 1 ohm if there are special grounding requirements.

Read the instructions carefully before installing the surge protector.

Generally, you need to connect a surge protector before connecting a signal cable to the router. This can protect electronic devices against surge over-voltage resulting from lightning strokes and other interferences, and minimize impact on the router.

The surge protector is serially connected to a signal cable, so the surge protector must satisfy the requirements of network performance indexes such as data transmission bandwidth, as well as the lightning protection performance requirement. Before installing a surge protector, consider such performance indexes of the surge protector as lightning protection, bandwidth, transmission loss, and port type.

The router supports the following types of surge protectors:

· Surge protector—Maximum discharge current 2.5KA/protection voltage 25V--SMB-75J/ SMB-75J-1W-10Mbps

· Surge protector—Maximum discharge current 2.5KA/protection voltage 25V-BNC-75K/ BNC-75K-10Mbps

· Surge protector (U port)—Maximum discharge current 3KA/common-mode 400V/differential mode 170V-RJ11

To install a surge protector:

1. Use a double-faced adhesive tape to stick the surge protector onto the router chassis, and make sure it is as close to the grounding screw of the router as possible.

3. Use the multimeter to measure whether the ground wire of the protector contacts well with the grounding screw of chassis.

4. Insert the outdoor network cable into the protector's IN end, and the cable connected to the router into the OUT end, and look at the indicators on the surge protector to verify that the connection is correct.

5. Use nylon ties to bundle the cables neatly.

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. Figure3-3 shows the pinouts of an RJ-45 connector.

Figure3-3 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 steady, pin 3: white/orange stripe, pin 4: blue steady, pin 5: white/blue stripe, pin 6: orange steady, pin 7: white/brown stripe, pin 8: brown steady.

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

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.)

Table3-1 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

Table3-2 Crossover cable pinouts

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

NOTE:

To avoid affecting communication quality, strictly follow the pinouts in the above tables when identifying or making the two types of Ethernet cables.

Making an Ethernet cable

1. Cut the cable to a required 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 correct 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) or the management Ethernet 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. Examine the status LED of the Ethernet ports. For more information about the LED status, see H3C SR6604-X/SR6608-X/SR6616-X Routers Hardware Information and Specifications.

Connecting a fiber cable

Transceiver module overview

When you use a fiber port, you need an SFP, XFP, SFP+, or QSFP+ transceiver module and a fiber cable with an LC or MPO connector. For the compatibility between the cards and transceiver modules, see H3C SR6600/SR6600-X Routers Interface Module Guide.

Figure3-4 SFP transceiver module

Figure3-8 QSFP+ transceiver module (MPO connector)

Fiber cable overview

CAUTION:

· Never exert a fierce force when you insert or remove a fiber connector.

· Never pull, press, or extrude the fiber fiercely.

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

Table3-3 Characteristics of single-mode and multi-mode optical fibers

Item	Single-mode optical fiber	Multi-mode optical fiber
Core	Small core (10 micrometers or less)	Larger core than single-mode optical 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

Table3-4 lists the allowed maximum tensile load and crush load for the fiber.

Table3-4 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. Figure3-9 and Figure3-10 show an LC connector and an MPO connector, respectively.

Figure3-9 LC connector

Installing transceiver modules and optical fibers

CAUTION:

If you are not to use a fiber port or transceiver module, insert dust plugs into the port or module. If you are not to connect an optical fiber, install dust caps for the fiber connector.

To install a transceiver module and optical fiber:

1. Wear an ESD wrist strap and make sure the wrist strap is reliably grounded.

2. Remove the dust plug from the target fiber port.

3. Pull the bail latch on the transceiver module upwards.

4. Take the transceiver module by its two sides and push the end without the bail latch gently into the port until it is firmly seated in the fiber port.

5. Remove the dust plug and dust cap from the transceiver module and fiber connector, respectively.

6. Connect the optical fiber to the transceiver module.

¡ LC connector—Identify the Rx and Tx ports on the transceiver module. Use the optical fiber to connect the Rx port and Tx port on the transceiver module to the Tx port and Rx port on the peer end, respectively.

¡ MPO connector—Orient the connector with the white spot on it facing right. Insert the MPO fiber connector straight into the transceiver module and push it slightly forward until it clicks into place.

7. Use cable ties to bind optical fibers every 150 mm (5.91 in).

8. Label optical fibers according to the cable labeling specifications.

Port configuration and management

Configuring a combo interface

A combo interface is a logical interface that contains an SFP port of a transceiver module and an RJ-45 Ethernet port. The two ports share one forwarding interface, so they cannot work simultaneously. When you enable either port, the other port is automatically disabled. You can select to activate a port as needed.

Use the display interface interface-type interface-number command to find out which port is an SFP port and which port is an RJ-45 Ethernet port.

· If the output includes "Media type is optical fiber," it means that the port is an SFP port. For example, the following output shows that GigabitEthernet 5/0/1 is an SFP port.

[Sysname] display interface GigabitEthernet 5/0/1

GigabitEthernet5/0/1 current state: DOWN

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:

Task	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.

Verifying transceiver modules

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:

Task	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.

For more information about the transceiver module displaying commands, see H3C SR6600/SR6600-X Routers Command References.

Rebooting a card or router

When upgrading and maintaining the system software image or configuration file for the router, you need to reboot the router. After you change the operating mode of a MPU or LPU, you must restart the corresponding module.

To reboot a router, use one of the following methods:

· Power off and then power on the router. This method might cause data loss, and is the least-preferred method.

· Immediately reboot the router at the CLI.

· Schedule a reboot at the CLI, so the router automatically reboots at the specified time or after the specified period of time.

The first method is called "cold reboot" or "cold startup". The second and third methods are called "warm reboot" or "warm startup", and can be used remotely.

For data security, if you reboot the router while the router is performing file operations, the router does not reboot.

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 the main startup configuration file does not exist, do not use the reboot command to reboot the router or the active MPU. In this case, you should specify the main startup configuration file first, and then reboot the active MPU.

To reboot the router immediately at the CLI:

Task

Command

Remarks

Reboot the router or the card in the specified slot immediately.

reboot [ slot slot-number ]

Available in user view.

If you do not specify the slot keyword, the command reboots the router, including the active MPU, standby MPU, and the LPUs.

To schedule a reboot:

Task

Command

Remarks

Specify a reboot time and date.

Dealing with console login password loss

CAUTION:

Dealing with console login password loss from BootWare menus requires device reboot and is service-disruptive.

How to deal with console login password loss depends on the state of password recovery capability (see Figure7-1). 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.

Cooling system failure

Symptom

When the temperature inside the router exceeds the upper threshold, the following information appears on the configuration terminal:

#Jun 14 11:54:38:178 2012 H3C DEVM/1/BOARD TEMPERATURE UPPER:

Trap 1.3.6.1.4.1.25506.8.35.12.1.16<hh3cBoardTemperatureHigher>: chassisIndex i

s 0, slotIndex 0.1

%Jun 14 11:54:38:179 2012 H3C DEVM/4/BOARD_TEMP_TOOHIGH: Board temperature is to

o high on Chassis 0 Slot 1, type is RSE-X2.

The output shows that the temperature inside the router has exceeded the upper threshold. In this case, the fans of the router will rotate at full speed.

Generally, after the fans rotate at full speed for a certain period, the temperature inside the router will drop below the upper threshold, and the following information appears on the configuration terminal:

#Jun 14 11:56:48:279 2012 H3C DEVM/1/BOARD TEMPERATURE UPPER:

Trap 1.3.6.1.4.1.25506.8.35.12.1.17< hh3cBoardTemperatureFormHigherToNormal >: chassisIndex i

s 0, slotIndex 0.1

%Jun 14 11:56:48:279 2012 H3C DEVM/4/BOARD_TEMP_TOOHIGH: Board temperature changes to normal on Chassis 0 Slot 1, type is RSE-X2.

The output shows that the operating temperature of the router restores to normal state.

When exceptions occur, the temperature inside the router might exceed the critical temperature threshold, and the following information appears on the configuration terminal in this case:

%Jun 14 12:06:58:436 2012 H3C DRVMSG/3/TempCritical:

CPU temperature is greater than alarm upper limit in slot 1, index is 1

At the same time, the ALM LED of the MPU is red, which indicates that the temperature inside the router is abnormal.

Solution

To resolve the problem:

1. Verify that the fans are running correctly.

2. Verify that the operating environment of the router is well ventilated.

3. Use the display environment command to identify whether the temperature in the router keeps rising.

For more information about the display environment command, see H3C SR6600/SR6600-X Routers Fundamentals Command Reference.

4. Power off the router immediately and contact H3C Support.

Ethernet port failure

Symptom

Use unshielded twisted pairs to connect Ethernet ports and a minimum of one end of the link that supports 100Base-TX. The following failures occur:

· No link is present for the end operating at 100 Mbps.

· A link is present for the end operating at 10 Mbps, but the physical layer LED (for example, the Active LED) keeps flashing, and the port cannot transmit or receive traffic correctly.

For the copper FE ports and GE ports, both the rate and duplex mode are auto-negotiated by default.

Solution

To resolve the problem:

1. Change the rate and duplex mode of a port by force, and make sure the rate and duplex mode of the local end are the same as the peer end.

2. If the problem persists, contact H3C Support.

HIM/MIM/MIC, cable, and connection failure

Symptom

System software image file missing errors

Symptom

When none of the main, backup, and secure system software image files exists, the system displays the following information at startup:

BootWare Validating...

Application program does not exist.

Please input BootWare password:

If you select 1 on the main BootWare menu, the system displays the following information:

Starting to get the main application file--cfa0:/main.bin!

The main application file does not exist--cfa0:/main.bin!

Starting to get the backup application file--cfa0:/backup.bin!

The backup application file does not exist--cfa0:/backup.bin!

Starting to get the secure application file--cfa0:/secure.bin!

The secure application file does not exist--cfa0:/secure.bin!

Booting App fails!

The name of the main, backup, and secure system software image files vary by user settings.

A possible reason for the errors is that the main, backup, and secure system software image files have been deleted or damaged.
