2. Verify that the SEM is operating correctly.
3. Verify that the console cable has been connected to the console port on the SEM.
4. Verify that the console cable has been connected to the correct serial port on the configuration terminal.
5. Verify that the console cable is in good condition and operates correctly.
6. If the issue persists, contact H3C Support.
Garbled terminal display
Symptom
Terminal display is garbled.
Solution
To resolve the issue:
1. Make sure the configuration terminal is configured with the same settings as the console port:
¡ Baud rate—9600 bps.
¡ Data bits—8.
¡ Parity—None.
¡ Stop bits—1.
¡ Flow control—None.
¡ Terminal type—VT100.
If you modify the settings for the console port of the gateway, configure the same settings for the configuration terminal.
Typically, the default baud rate of the configuration terminal is 9600 bps. However, the default baud rate is 115200 bps in some cases. Configure the baud rate as required.
For more information about the default baud rate of console ports on a gateway, see the hardware information and technical specifications for that gateway on the H3C official website at https://www.h3c.com/en/Support/Resource_Center/Technical_Documents/Security/.

Ethernet twisted pair cable
An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly transmits analog signals and is advantageous in transmitting data over shorter distances. The maximum transmission distance is 100 m (328.08 ft).
RJ-45 connector
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure6-3 shows the pinouts of an RJ-45 connector.
Figure6-3 RJ-45 connector pinout diagram
Cable pinouts
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.

To ensure normal communication, the pins for sending data on one port should correspond to the pins for receiving data on the peer port. When both of the ports on the two devices are MDI or MDIX, a crossover Ethernet cable is needed. When one port is MDI and the other is MDIX, a straight-through Ethernet cable is needed.
If an RJ-45 Ethernet port with MDI/MDIX autosensing enabled can automatically negotiate pin roles. The RJ-45 Ethernet ports support MDI/MDIX. By default, MDI/MDIX is enabled on a port.
Making an Ethernet twisted pair cable
1. Cut the cable to a required length with the crimping tool.
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 lie 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 tool until you hear a click.
6. Repeat the above steps with the other end of the cable.
7. Use a cable tester to verify the connectivity of the cable.
Optical fiber
|
|
CAUTION: Use the same types of transceiver modules, pigtail cords, patch cords, and fiber cables. If you use single-mode optical fibers, the transceiver modules, pigtail cords, patch cords, and fiber cables must be single-mode. |
Optical fiber
Optical fibers are widely used in fiber-optic communications, which are advantageous for long-distance communications.
Optical fibers can be classified into the following types:
· Single-mode fiber—It has a core size of 10 µm or smaller, and has a lower modal dispersion. It carries only a single ray of light. It is mostly used for communication over longer distances.
· Multimode fiber—It has a core size of 50 µm, 62.5 µm, or higher, and has a higher modal dispersion than single-mode optical fiber. It is mostly used for communication over shorter distances.

Optical fiber cable
An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube. Optical fiber cables fall into single-mode and multimode.
Patch cord
A fiber that has connectors at both ends is called a patch cord. A patch cord connects one optical device to the other for signal routing. Patch cords fall into single-mode and multimode patch cords.
· Single-mode patch cord—The jacket is yellow. It permits transmission over longer distances.
· Multimode patch cord—The jacket is orange. It permits transmission over shorter distances.
Patch cords are classified into SC, LC, FC, and so on based on interface type. The length of a patch cord can be 0.5 m (1.64 ft), 1 m (3.28 ft), 2 m (6.56 ft), 3 m (9.84 ft), 5 m (16.40 ft), 10 m (32.81 ft), and so on.
Pigtail cord
A pigtail cord is an optical fiber that has an optical connector on one end and a length of exposed fiber on the other. The end of the pigtail is fusion spliced to a fiber, connecting the fiber cable and transceiver.
Pigtail cords fall into single-mode (yellow) and multimode (orange), and can also be classified into SC, LC, FC, and so on based on interface type.
Fiber connector
Figure6-6 SC connector
Figure6-8 MPO connector
Precautions
· Make sure the fiber connector and fiber type match the transceiver module type.
· The fiber ports on some modules have shielded covers. Remove the shielded covers before using the fiber ports. Fiber ports must be installed with shielded covers when they are not in use. Keep them safely.
· Fiber connectors must be protected under safe and reliable outer packing, and be fitted with dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take care not to scratch their end face. Replace the dust cap if it is loose or polluted.
· Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the fiber connector. You can brush the end face only in one direction. You also need to brush the end face of the fiber port.
· 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.
7 Engineering labels
Engineering labels (labels for cables and labels for devices) are used to identify cables and devices for easy maintenance after installation.
Labels for cables
You can affix labels to network cables (twisted-pair cables and optical fibers) and power cords (AC and DC power cords).
Labels for network cables
A label for network cables is L-shaped with fixed dimensions. The light-blue dividing lines on the label help to specify more clearly the position of the cable. For example, there is one dividing line between the rack number and the chassis number and another one between the chassis number and the slot number. The cut dotted line helps to fold the label when you affix it to the cable. A mark "TO:" is located at the lower right corner of the label to identify the peer end of the cable on which the label is affixed.
As shown in Figure7-1, write a network cable label as follows:
· Write the position of the cable in Area 1.
· Write the position of the cable on the peer end in Area 2.
· Area 3 is the part that is folded up inside the label when the label is affixed to the cable.
Figure7-1 Label for network cables
|
(1) Dividing line |
(2) Cut dotted line |
Labels for power cords
Attach a label for power cords to the identification plate on a cable tie that binds the power cords. The identification plate has an embossment of 0.2 × 0.6 mm (0.008 × 0.02 in) around (symmetric on both sides), and the area in the middle is for affixing the label.
A mark "TO:" is located at the upper left corner of the label to identify the peer end of the cable on which the label is affixed. You can write the position of the peer device, control cabinet, distribution box, or power socket. The meaning of the dividing lines is the same as labels for network cables.
Figure7-2 Label for power cords
|
(1) Cable tie |
(2) Dividing line on the label |
Generic labels
A generic label is bar-shaped with fixed dimensions. It is applicable to all cables. A mark "TO:" is located at the upper left corner in the right area of the label to identify the peer end of the cable on which the label is affixed. The meaning of the dividing lines is the same as labels for network cables.
Figure7-3 Generic label
|
(1) Dividing line on the label |
(2) Cut dotted line |
Labels for devices
A device label is used to identify the device name, model, address, installation date, and so on.
Filling in labels
You can print or write desired contents on labels. HP recommends that you print labels.
To print labels, select a label printer and a label template as needed. For more information about using a label printer, see the user guide of the printer.
To write labels, use black markers. A marker has two nibs. Be sure to use the smaller nib to write labels.
Affixing labels
After printing or writing a label, remove the label from the bottom page and affix it to the network cable, or the identification plate of the power cord.
Affixing a label to a network cable
Typically, a label is affixed 2 cm (0.79 in) away from the connector on a network cable. You can affix the label to other positions as needed. Figure7-4 shows how to affix a label when a cable is laid vertically.
Figure7-5 shows the affixed labels when the cable is laid vertically and horizontally.
Figure7-5 Affixed labels
Affixing a label to a power cord
Stick the label to the recessed rectangular area on the identification plate. You can stick the label to either side of the identification plate. Be sure to affix the labels on the same side of the identification plates.
A cable tie is bundled 2 cm (0.79 in) away from the connector. You can affix the label to other positions as needed. Figure7-6 shows how to affix a label when a cable is laid horizontally.
Bind cable ties on both ends of a cable. After the bundling, the finished identification plate must be on top of the cable in horizontal cabling, or on the right side of the cable in vertical cabling. Make sure the label is facing out, as shown in Figure7-7.
Affixing a generic label
The requirements for affixing a generic label are the same as affixing a label on a network cable. For more information, see "Affixing a label to a network cable." For the example of affixed labels, see Figure7-8.
Figure7-8 Affixing a generic label
Affixing a label to a device
Remove the device label and stick it to the device. You can stick a device label to any desired position on the device.
Guidelines
· When you print, write, or affix labels, keep the labels clean.
· Do not use ink-jet printers and ink pens.
· Affix labels with good order in alignment.
· Avoid cable bents or other positions that might affect cable installation when you stick a label or bundle a cable tie with a power cord identification plate.
· Bundle cable ties at the same positions of power cords, with identification plates on the same side.
· The positions of "up," "down," "right" or "left" are all based on the viewpoint of the engineering person who is working on the label.

Engineering labels for DC power cords
These labels are affixed to DC power cords that provide power for racks, and the protection grounding cables including the –48V, PGND, and RTN cables. The labels for DC power cords are affixed to one side of the identification plates on cable ties.
Table7-4 Information on labels affixed to DC power cords
|
Content |
Meaning |
|
MN(BC)-–48Vn |
· Loaded cabinet side—Only MN is used to identify the cabinet number (row number and column number in the equipment room). · Power cabinet side—MN identifies the row and column number of the power distribution equipment like the control cabinet and distribution box. BC identifies the row and column number of the –48V connector (if there is no row number or column number, or the connector can be identified without them, BC can be omitted). RTN and PGND have no row and column number for identification. · n—Power port number in down-top and left-right order, in the range of 1 to 3. |
|
MN(BC)-RTN |
|
|
MN(BC)-PGND |
The label only carries location information about the peer equipment, control cabinet, or distribution box, while information about the local end is not necessary. Table7-4 lists information about two –48V power supplies on the label. Give information for other DC voltages (such as 24V, 60V) in similar methods.
Make sure labels are affixed in the correct direction. After the cable ties are bundled onto the cable, the identification plates with the labels must face up, and the text on the labels in the same cabinet must be in the same direction, as shown in Figure7-12.
Figure7-12 Example of labels on a DC power cord
· A01/B08––48V2 (loaded cabinet side)—The power cord is –48V2 DC supply, which is from the 8th connector on the second row of –48V bus bar in the cabinet on Row A, and Column 1 in the equipment room.
· B03––48V2 (distribution box side)—The power cord is –48V2 DC supply, which is from the loaded cabinet on Row B, Column 03 in the equipment room.
In the power distribution box (or the first power cabinet of a row in the transmission equipment room), every terminal block on the –48V connector bar has a numeric identification. For example, in the above label of "A01/B08--48V2", "08" (or sometimes "8") is the numeric identification of the terminal block.
PGND and RTN are two copper bars, on which the terminal blocks are short-circuited, so which terminal is connected makes no difference. You only need to give the row and column numbers of the power distribution box, instead of giving the specific serial number of the terminal block on the copper bar. For example, if the label on the loaded cabinet side is "A01-RTN", it means that the power cord is an RTN that connects RTN copper bar in the power distribution box on Row A, Column 01 in the equipment room. Give information on the labels for PGND cables in the similar way.
Engineering labels for AC power cords
These labels are affixed to the AC power cords that provide power for cabinets and protection grounding cables, including POWER, RTN, and PGND cables. The 220 VAC cables and related PGND and RTN cables are covered with insulating sheath, so the labels only need to contain "AC" and the cabinet number. The labels for AC power cords are affixed to one side of the identification plates on cable ties.
Table7-5 Information on labels affixed to AC power cords
|
Content |
Meaning |
|
MN-AC |
MN: Rack number (row number and column number in the equipment room) or the location of the socket where the power is led in. The location of the socket is marked according to onsite situation. If the sockets can be identified by row number and column number, they can be numbered following the same rule for the rack number. Otherwise, specify the detailed locations to avoid confusing with other sockets. |
The label only carries location information about the peer equipment and the power socket, while information about the local end is not necessary. Make sure labels are affixed in the correct direction. After the cable ties are bundled onto the cable, the identification plates with the labels must face up, and the text on the labels in the same cabinet must be in the same direction, as shown in Figure7-13:
Figure7-13 Example of labels on an AC power cord
· A01-AC (loaded cabinet side)—The power cord is connected to the socket of Row A and Column 01 in the equipment room.
· B01-AC (power socket side)—The power cord is connected to the loaded cabinet of Row B, Column 01 in the equipment room.
Engineering labels for devices
These labels can be affixed to any device.
You can fill in the device name, model, IP address, serial number, installation address, and installation date on a device label.
Figure7-14 Example of a device label
8 Cabling recommendations
Routing cables
The cable management brackets are installed on the two sides of the front panel of the gateway. As a best practice, route cables from the left and right sides of the gateway, as shown in Figure8-1.
Figure8-1 Routing cables (M9000-X06)
Routing power cords
When you route power cords, take consideration of the layout of the equipment room, including the locations of the power distribution cabinet, AC power receptacles, and lightning protection box. Place all re-connecting facilities, such as receptacles, at the rack bottom (Do not place them at a location out of the rack and easy to reach.)
The power supplies are located at the rear panel of the gateway. As a best practice, route power cords from the left and right of the rear panel.
General cabling requirements
Minimum curvature radius of cables
· The curvature radius of an attached power cord, 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 attached 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.
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 attached, 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). |
Prerequisites
Label cables before you route or bundle them.
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 they are not kinked or bent.
Figure8-2 Correct and incorrect cable binding
· 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 cords 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 cord 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 type of 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 Figure8-3.
Figure8-3 Cutting cable ties
· When you bend cables, bind them as shown in Figure8-4. To avoid excessive stress causing cable core break, do not tie up the cables in the bending area.
Figure8-4 Binding cables where they must be bent
· Route, bind, and attach excess cables for easy, safe maintenance activities and correct operations.
· Do not tie power cords to 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 as shown in Figure8-5.

9 Repackaging the gateway
This chapter describes how to repackage the gateway chassis, power supplies, and modules.
Removing cables from the gateway
Before repackaging the gateway, remove all cables such as the power cord, console cable, twisted pair, optical fiber, and grounding cable from the gateway.
Removing the power cord
1. Switch off the circuit breakers at the input end of all power cords.
2. Wear an ESD wrist strap, and make sure it has a good skin contact and is reliably grounded.
3. Remove the power cord plug:
¡ AC power cord—Remove the cable tie that secures the power cord, and then pull out the plug.
¡ DC power cord—Remove the cable tie that secures the power cord, loosen the fastening screw on the power cord, and then pull out the plug.
Removing the console cable
1. Pull the RJ-45 connector of the console cable out from the console port of the gateway.
2. Pull the DB-9 connector of the console cable out from the serial port of the PC.
Removing the grounding cable
1. Loosen the two screws at the grounding holes (located at the rear panel and marked with a grounding sign) of the chassis, and then remove the grounding cable from the chassis.
Removing the twisted pair and optical fiber
You must remove twisted pairs and optical fibers from all the interfaces of the gateway.

|
WARNING! Before removing a power supply, switch off the circuit breakers at the input end of all power cords, and remove all the power cords to avoid device damage and bodily injury. |
1. Prepare the packing bag and box of the power supply. Make sure the bag is clean, dry, and not damaged.
2. Remove all power supplies from the chassis, and then install filler panels to the empty slots.
For how to remove a power supply and install a filler panel, see "Replacing a power supply."
3. Put the removed power supply into the anti-static bag.
4. Place the foam cushion over the power supply.
5. Place the power supply and the foam cushion in the packing box, and seal the box with tape.
Repackaging a module
1. Prepare the original packing materials, including the anti-static shielding bag, foam cushion, and packing box, for a module. Make sure these packing materials are clean, dry, and not damaged.
2. Remove the transceiver modules, if any, from the module. If no transceiver module is installed on the module, go to the next step.
For how to remove a transceiver module, see "Replacing a transceiver module."
3. Remove all modules from the chassis slots, and install filler panels to the empty slots.
For how to remove a module and install a filler panel, see "Replacing a module."
4. Put the removed module into the anti-static bag.
5. Place the foam cushion over the module.
6. Put the module and the foam cushion into the box, and seal the box with tape.
(Optional.) Removing the air filter doors
See the user guide provided with the air filter doors to remove the air filter doors, if any.
Removing cable management brackets
Before repackaging the gateway chassis, remove the cable management brackets from the chassis.
The cable management brackets have been installed on the two sides of the gateway when the gateway is shipped. You only need to attach the cable guides to the cable management bracket.
To remove the cable management brackets from the gateway:
1. Prepare the packing bag of the cable management brackets. Make sure the bag is clean, dry, and not damaged.
2. Use a Phillips screwdriver to loosen the screws that attach the cable management brackets to the chassis, and then remove the cable management brackets.
3. Put the cable management brackets into the bag.
Figure9-1 Removing the cable management brackets
Removing the chassis from the rack
The gateway is heavy. If possible, use a mechanical lift to move the gateway.
To remove the chassis from the rack:
1. Prepare the wooden carton and packing bag of the chassis. Make sure the carton and bag are clean, dry, and not damaged.
2. Remove the top cap and side panels from the wooden carton.
3. Use a Phillips screwdriver to loosen the screws that attach the mounting brackets to the rack.
4. Use at least four persons to slide the chassis outwards along the slide rails. When most part of the chassis is removed from the slide rails, lift up the chassis by holding the handles at the chassis sides to completely remove the chassis from the rack.
5. Put the chassis onto the pallet base of the wooden carton.
Figure9-2 Removing the chassis from the rack (M9000-X06 as an example)
Repackaging the gateway chassis
The packing method might vary by gateway model and shipping batch. Select an appropriate packing method based on the packing materials provided for the gateway.
Securing the chassis by using L-type brackets
1. Align the left and right edges of the chassis bottom with the left and right positioning lines respectively on the wooden pallet base. See Figure9-3 for the wooden pallet base.
2. Use screws to attach the L-type brackets to the chassis, as shown by callout 1 in Figure9-4.
3. Move the chassis so that the mounting holes on the horizontal ear of the L-type brackets align with the mounting holes on the wooden pallet base. Use screws to attach the L-type brackets to the wooden pallet base, as shown by callout 2 in Figure9-4.
