Backplane

The backplane of an S12500 switch is located inside the chassis. It provides high-speed data switching between switching fabric modules and line cards, and exchanges management and control signals between MPUs and line cards/switching fabric modules. The backplane provides the following capabilities:

• Provides communication channels for signal exchange between cards.

• Supports hot-swapping of cards.

• Identifies card type.

• Supplies power to MPUs, line cards, switching fabric modules, fan trays, and power modules when

connected to the power frame.

• Provides monitoring channels to monitor power module status.

Fan tray

A fan tray contains fan units. The dimension of each fan unit is 120 × 120 × 38 mm (4.72 × 4.72 ×1.50 in).

Both the S12508 and the S12518 use an upper fan tray at the top and a lower fan tray at the bottom. Each fan tray comprises 12 fan units and one fan monitoring board.

S12500 fan trays provide the following functions:

• Effective heat dissipation and single-point of failure protection.

• Status monitoring, including fan rotation speed monitoring and fault alarming.

• Fan speed can be controlled by the MPU or automatically adjusted based on temperature. The

S12508 and S12518 have four groups of fans. Speed adjustment is done on a per-group basis to decrease noise and improve energy efficiency.

• Each fan tray has two LEDs on the front panel to show its operating status.

• Hot swappable. The fans receive DC power from the backplane, and are hot swappable.

CAUTION:

The S12508 and S12518 use different fan trays, and do not support the intermixing of fan trays.

Figure 5 shows the S12508 fan tray. The physical view of the S12518 fan tray is similar.

Preparing for installation

Safety recommendations

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.

General safety recommendations

• Take adequate safety measures to avoid injury and switch damage. For example, wear an

ESD-preventive wrist strap.

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

• Keep the chassis clean and dust-free.

• Do not place the switch on a moist area and avoid liquid surrounding the switch.

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

• Move the switch and heavy components (such as the power supplies or chassis) with other people

rather than doing that alone.

Electricity safety

• Clear the work area of possible hazards, such as ungrounded power extension cables, missing

safety grounds, and wet floors.

• Locate the emergency power-off switch in the room before installation. Shut the power off at once in

case accident occurs.

• Unplug all the external cables (including power cables) before moving the chassis.

• Do not work alone when the switch has power.

• Always check that the power has been disconnected.

ESD prevention

CAUTION:

To prevent the electronic components from being damaged by the electrostatic discharge (ESD), you should not only take ESD measures where the switch is located, but also take the following precautions:

• Always wear an ESD-preventive wrist strap when installing components, especially the electronic printed

circuit boards.

• Hold a PCB by its edges. Do not touch any electronic components or printed circuit.

• Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the

range of 1 to 10 megohm (Mohm) between human body and the ground.

To use the ESD-preventive wrist strap:

1. Wear the wrist strap on your wrist.

Page 28

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

3. Insert the ESD-preventive wrist strap into the specially designed hole on the switch chassis or attach

it to the grounding screw of the chassis with the alligator clips.

4. Make sure that the ESD-preventive wrist strap is well grounded.

Figure 15 Use an ESD-preventive wrist strap

Switch moving

When you move an H3C S12500 switch, note the following guidelines:

• Remove all the external cables (including the power cables) before moving the chassis.

• For personal safety, have several persons to move the switch carefully.

• When moving the switch, hold the handles at both sides of the chassis. Do not hold the plastic panel

of the chassis, the handle of the fan tray, the handle of the back cover of the chassis, or the air vents of chassis. Any attempt to carry the switch with these parts may cause equipment damage or even bodily injury.

WARNING!

For personal safety, at least four people are required to move an S12518 switch.

Laser safety

The H3C S12500 switches are Class 1 laser devices.

Page 29

WARNING!

Do not stare into any fiber port when the switch has power. The laser li

ht emitted from the optical fiber

may hurt your eyes.

Examining the installation site

The H3C S12500 Routing Switch Series can only be used indoors. To ensure that the switch works properly and to prolong its service lifetime, the installation site must meet the following requirements:

Weight support

Evaluate the floor loading as compared to the actual weight of the switch and its accessories (such as cabinet, chassis, cards, and power supply units), and make sure that the floor can support the weight of the cabinet and the switch chassis.

TIP:

When you evaluate the floor loading, consider router

capacity expansion (for example, installing a ne

card) in the future.

Temperature

To ensure the normal operation of the switch, make sure that the room temperature meets the requirements described in Table 8.

Table 8 Temperature r

equirements

Temperature Range

Operating temperature

Long term: 0°C to 40°C (32°F to 104°F) Two hours: –10°C to +50°C (14°F to 122°F) (no more than 96

hours of continuous operation in less than 15 days in one year)

Storage temperature –40°C to +70°C (–40°F to +158°F)

CAUTION:

If condensation appears on the switch when you move it to a high-temperature environment, dry the switch before powering it on to avoid short circuits.

Humidity

Maintain appropriate humidity in your equipment room, as described in Table 9.

Table 9 Humidity requirements

Humidity Range

Operating humidity (noncondensing) 5% to 95%

Storage humidity (noncondensing) 5% to 95%

Page 30

Lasting high relative humidity can cause poor insulation, electricity creepage, 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.

Cleanness

Dust buildup on the chassis may 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 10 Dust concentration limit in the equipment room

Substance Concentration limit (particles/cu m)

Dust particles ≤ 3 x 104 (no visible dust on the tabletop over three days)

NOTE:

Dust particle diameter ≥ 5 μm

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 11.

Table 11 Harmful gas li

mits in the equipment room

Gas Average (mg/m

) Max. (mg/m3)

SO2 0.3 1.0

H2S 0.1 0.5

NO2 0.004 0.15

1.0 3

0.1 0.3

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions:

• 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.

• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or

overcurrent caused by lightning strikes.

Grounding

Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD is essential to the operating reliability of your switch.

Page 31

Make sure that the resistance between the chassis and the ground is less than 1 ohm.

Power supply

Perform the following steps to satisfy the power supply requirements of the S12500 Routing Switch Series:

1. Calculate the system power consumption.

2. Select power supplies according to the system power consumption and power supply mode.

To ensure normal operation of the switch, make sure the maximum output power of the power supplies is greater than the system power consumption of the switch (reserve certain power for redundancy). After determining the system power consumption and power supply mode (AC or DC power supply), you can select power supplies as needed.

3. Check that the power source on the installation site satisfies the power input of the power supplies.

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

NOTE:

For the power consumption and power module

specifications of the switch, see the chapter “Appendix

Technical specifications.”

Any attempt to carry the switch with these parts may cause equipment damage or even bodily injury.

Installing slide rails and cage nuts to the rack

Installing slide rails

Before installing the switch to the rack, install slide rails to the rack. If the rack has slide rails, skip this section.

NOTE:

• Before installing the slide rails, check that the slide rails can support the weight of the switch. For the

weights of the S12500 Routing Switch Series, see the chapter “Appendix A Technical specifications.”

• Besides slide rails, you can use a rack shelf to support the switch. This document describes how to install

slide rails only.

• Slide rails or rack shelves are not provided with the switch. Prepare them yourself, or order them from

H3C.

The following uses a 19-inch rack as an example to describe the installation procedures. The height of the front panel of the rack is a measurement of one rack unit (RU) (44.45 mm, or 1.75 in). As shown in callout 2 in Figure 19, e

ach 1 RU has three holes with center-to-center spacing between the holes of 15.87 mm (0.63 in), 15.87 mm (0.63 in), and 12.70 mm (0.5 in). When installing the slide rails, make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area between holes.

To install the slide rails:

1. Mark the position of the slide rails on the rack.

2. Align the screw holes on the two sides of the slide rails with the corresponding holes on the rack,

and then fasten the screws.

3. Install the other slide rail in the same way. Keep the two slide rails at the same height so that the

switch can be placed evenly.

NOTE:

• The appearance and installation methods of slide rails depend on the slide rail types.

• To ensure stability of the rack, install the slide rails to the lowest possible position when installin

a single switch on the rack. To install multiple switches on the rack, mount the heaviest switch at the bottom of the rack.

Installing cage nuts

Before mounting the chassis to the rack, install cage nuts to the front square-holed brackets of the rack.

To install cage nuts to the rack:

1. Align the mounting bracket with the left rack post, making sure that the bottom edge and the slide

rail are level. Mark the positions of the cage nuts on the rack post according to the installation holes on the mounting bracket (each installation hole on the mounting bracket corresponds to one cage nut).

2. Insert one edge of a cage nut into the hole.

3. Compress the other edge of the cage nut to push the cage nut fully into the hole.

4. Repeat steps 3 and 4 to install cage nuts to all the marked positions on the right rack post.

Connecting the switch to the network through a fiber Ethernet port

Use an optical fiber to connect an XFP, SFP, or SFP+ port on the switch to the network. You must install a transceiver module to the switch, and then insert the fiber connector to the module.

Introduction to fiber connector

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 and the transit dispatching of the system more flexible. Among various fiber connectors, only the LC connector is described here.

Figure 46 LC connector

Precautions

Follow these precautionary steps:

• When selecting a fiber network facility, make sure that the type of the connector and the fiber

matches the adopted fiber port.

• Be sure to install the dust cover if the fiber port is not connected to a fiber connector.

• Some invisible rays may be emitted from the fiber port if the fiber port is not connected to a fiber

connector or the dust cover is removed. Therefore, never stare at the fiber port directly.

• Never bend or curve a fiber when connecting it.

Installing a transceiver module

The installation of an XFP, SFP, and SFP+ module is similar. The following uses an SFP module as an example.

CAUTION:

Do not touch the golden finger of an SFP module during installation.

To install an SFP module:

Page 64

1. Put on an ESD-preventive wrist strap, and make sure that it has close skin contact, and is well

grounded.

2. Take the SFP module out of the package. Close the clasp by pushing it up over the SFP+ module,

and then gently insert the SFP+ module into the interface slot until it clicks into place, as shown in

Figure 47.

Figure 47 Install an SFP

module

NOTE:

• Do not remove the dust plug of the SFP module port before installing an optical fiber.

• For an SFP+ module installed with an optical fiber, remove the fiber before you install the SFP+ module

into the slot.

Connection procedure

To connect an optical fiber:

1. Put on an ESD-preventive wrist strap, and make sure that it has close skin contact, and is well

grounded.

2. Remove the protective cap from the fiber connector, and use dust free paper and absolute alcohol

to clean the end face of the fiber connector.

• The cabinet is fixed.

• The switch is installed.

The installation involves the following materials:

• FMT

• M5×10 self-tapping screws (two screws for one FMT)

Installation procedure

To install the fiber management tray:

Page 66

1. Align the FMT and the installation holes on the column of the cabinet.

2. Use a Phillips screwdriver to fix each FMT with two M5×10 self-tapping screws.

Figure 50 Install FMTs

Cable routing recommendations

Interface cables and power cords should be separately routed. Reasonable cable routing can improve efficiency by facilitating installation and removal of fan trays, PEM, and some other components.

• Interface cables of an S12508 and S12518 are routed through the upper and lower cable

management brackets on the chassis and bound at cabling racks on chassis sides, depending on the available equipment room condition.

• Put all the data signal cable adapters neatly under the chassis (instead of any places outside the

chassis in case of unexpected damages).

• The power cords run along the left-rear 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.

CAUTION:

• Long cables can be bound with cable ties. Do not bind cables at the air exhaust vent to prevent the

cables from aging too fast. For more information, see the chapter “Appendix E Cable management.”

• Fix cables as near the switch as possible. The cables between the fixing point and switch interfaces mus

be bound loosely.

• To identify cables, you can stick labels on them. For more information, see the chapter “Appendix F

Engineering labels for cables.”

Page 67

Table 17 display device command output description

Field Description

Slot No.

Slot number of a card (standalone mode); slot number of a card on the specified member switch in the format of member ID/slot number (IRF mode)

Brd Type

Hardware type of a card, which can be:

• Specific card model, such as LST1MRPNC1, which is the same as the silkscreen.

• NONE: No card is in the slot.

• UNKNOWN: The card is not supported by the software version and thus cannot

start normally.

Brd Status

Card status, which can be:

• Absent: No card is in the slot.

• Master: The card is an active main board (AMB).

• Slave: The card is a standby main board (SMB).

• Normal: The card is an interface card and operates normally.

• Fault: The card in the slot has not started or fails.

• Off: The card is not powered on.

• Illegal: The card is not supported by the software version and thus cannot start

normally.

Subslot Num Number of subcards

Sft Ver

Software version of the current card, which can be:

• Specific software version: The software version of the switch.

• NONE: No card is in the slot.

• Mismatched: The software version does not support the card and thus cannot be

uploaded.

Rebooting your switch

When a fault occurs to a running switch, you can remove the fault by rebooting the switch.

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

• Power on the switch after powering it off, which is also called hard reboot or cold start. Powering off

a running switch causes data loss and hardware damages, and therefore this method is not recommended.

• Trigger an immediate reboot at the command line interface (CLI).

• Enable the scheduled reboot function at the CLI. You can set a time at which the switch can

automatically reboot, or set a delay so that the switch can automatically reboot within the delay.

Page 70

The last two methods are command line operations. Reboot at the CLI is also called hot start. It is mainly used to reboot a switch in remote maintenance, without performing hardware reboot of the switch.

Follow these steps to reboot a switch:

To do… Use the command… Remarks

Reboot a card, or the whole system immediately (standalone mode)

reboot [ slot slot-number ]

Optional Available in user view

Reboot a card, a member switch, or the whole system immediately (IRF mode)

reboot [ chassis chassis-number [ slot slot-number ] ]

Optional Available in user view

Enable the scheduled reboot function and specify a specific reboot time and date

schedule reboot at hh:mm [ date ]

Optional The scheduled reboot function is

disabled by default. Available in user view

Enable the scheduled reboot function and specify a reboot waiting time

schedule reboot delay { hh:mm | mm }

Optional The scheduled reboot function is

disabled by default. Available in user view

CAUTION:

• Switch reboot may result in an interruption of ongoing services. Use these commands with caution.

• Before the switch reboots, use the save command to save the current configurations.

• Before the switch reboots, use the commands of display startup and display boot-loader to check if the

configuration file and boot file to be used at the next boot are configured.

• The precision of the rebooting timer is 1 minute. One minute before the rebooting time, the switch

prompts “REBOOT IN ONE MINUTE” and reboots in one minute.

• If you do not specify the slot keyword, or reboot the AMB, the reboot command reboots the switch.

• If you are performin

file operations when the switch is to be rebooted, the system does not execute the

reboot command for security.

Enabling power supply management

If power supply management is not enabled when you add a new card by inserting it into the slot or starting power supply to the card by using the power-supply command, the system directly powers on the card, and the power supply may become unstable or the system may restart because of overloading.

If power supply management is enabled when you add a new card by inserting it into the slot or starting power supply to the card by using the power-supply command, the system compares the maximum power consumption of the card against the available power (including the redundant power supply). If the former is not greater than the latter, the system supplies power to the card, otherwise, the system does not supply power to the card.

Follow these steps to enable power supply management:

To do… Use the command… Remarks

Enter system view system-view —

Enable power supply management (standalone mode)

power-supply policy enable

Required Enabled by default

Enable power supply management on a specified member switch (IRF mode)

power-supply policy enable chassis chassis-number

Required Enabled by default

Configuring the number of redundant power modules

Redundant power modules are reserved for power module backup and power module threshold alarming. With multiple redundant power modules configured in the system, if a power module fails or the system power supply is overloaded, the system automatically enables a redundant power module. As a result, the number of redundant power modules decreases by one.

Follow these steps to configure the number of redundant power modules:

To do… Use the command… Remarks

Enter system view system-view —

Enable power supply management (standalone mode)

power-supply policy enable

Required Enabled by default

Page 72

To do… Use the command… Remarks

Enable power supply management on a specified member switch (IRF mode)

power-supply policy enable chassis chassis-number

Required Enabled by default

Configure the number of redundant power modules (standalone mode)

power-supply policy redundant module-count

Required By default, the number of

redundant power modules depends on the reserved power, which you can display with the display power-supply command.

Configure the number of redundant power modules on a specified member switch (IRF mode)

power-supply policy chassis

chassis-number redundant module-count

Required By default, the number of

redundant power modules depends on the reserved power, which you can display with the display power-supply command.

NOTE:

If power supply management is disabled, the system does not reserve any redundant power module. In this case, you can also use the power-supply policy redundant command to configure the number of redundant power modules, and this configuration will take effect after power supply management is enabled.

Manually starting or stopping power supply to a card

When the switch is operating, you can start or stop power supply to a card to adjust the system available power as needed.

Follow a step below to start or stop power supply to a card:

To do… Use the command… Remarks

Start or stop power supply to the specified card (standalone mode)

power-supply { on | off } slot slot-number

Optional The specified card cannot be a

main board or a switching fabric module.

Available in user view

Start or stop power supply to the specified card of a specified member switch (IRF mode)

power-supply { on | off } chassis

chassis-number slot slot-number

Optional The specified card cannot be a

main board or a switching fabric module.

Available in user view

Page 73

CAUTION:

Before starting power supply to a card, confirm whether the power module is overloaded after supplyin

power to the new card. If the maximum power consumption of the system is greater than the available power after supplying power to the new card, the system performs one of the following options:

• With power supply mana

ement enabled, the system does not supply power to this card because of the

self protection mechanism.

• With power supply mana

ement disabled, the system becomes unstable or the switch reboots because

of power module overload.

• For more information about power supply management, see “Enabling power supply management.“

Allocating IDs for AC power modules

NOTE:

• This section is applicable to AC power supply system PSE9000 only. To view the model of a power

supply system, use the display power-supply command.

• For PSE9000-A power supply system, the system can automatically set the power module ID as the slo

number where the power module is plugged, as shown in Figure 51 and Figure 52.

After the system starts up, each AC power module is allocated a unique local ID randomly. The randomly allocated ID is not convenient for device management, daily maintenance, and fault location because the randomly allocated ID is not related with the slot in which the AC power module resides. You must manually allocate IDs for the AC power modules after the installation of the switch for future management. It is recommended to allocate IDs for AC power modules the same as the numbers of the slots where the power modules reside, as shown in Figure 51 and Figure 52.

CAUTION:

Before you hot plug an AC power module, perform the following steps to avoid allocating one ID to multiple AC power modules:

• Wait for at least three seconds after you plug an AC power module into the AC power module

slot, and

then you can plug in another AC power module.

• Wait for at least 15 seconds after you plug an AC power module out of the AC power module

slot, and

then you can plug out another AC power module.

After the power-supply led-blink command is executed, the LED of the corresponding power module flashes for a period of time to show you the location of the power module. You can configure the time when the LED flashes and how long the LED keeps flashing. If you execute the command without specifying a power module ID, the LEDs of all power modules flash one by one in the ascending order of the power module IDs.

NOTE:

When you allocate IDs to the AC power modules, and then after a period of time, reboot the switch

usin

the following guidelines:

• If the locations of the AC power modules do not change or some AC power modules are plu

ed out

during this period of time, the IDs of the AC power modules do not change after the switch reboots;

• If the locations of the AC power modules are changed or some new AC power modules are plu

ed in during this period of time, the AC power modules are allocated new IDs randomly after the switch reboots.

Follow these steps to allocate IDs for AC power modules:

To do… Use the command… Remarks

Enter system view system-view —

Configure the time when the LED of the specified power module flashes and how long the LED keeps flashing (standalone mode)

power-supply led-blink [ module id ] [ blink-time value ] [ delay-time value ]

Isolating a card and locating card faults

When the switch detects a card failure or upgrades a logic of the CPU daughter card on a line card, you can isolate the faulty card or the CPU daughter card to prevent it from forwarding data packets. This

Page 82

operation allows for convenient on-site fault location or upgrading while causing no interference on the operation of the system and services of other cards.

After isolating a card, you can use the test diag-offline command to collect the fault detectio n information of the card.

Follow these steps to isolate a card and locate card faults:

To do… Use the command… Remarks

Enter system view system-view —

Isolate the specified card (standalone mode)

Required The fault detection information will be

displayed and saved in logs in the root directory of the flash. Each log is named in the format of diag_slot_time, where slot indicates the location of the card and time indicates when the fault detection operation is performed.

Locate the card problem for a card on a specified member switch (IRF mode)

test diag-offline chassis chassis-number slot slot-number

Required The fault detection information will be

CAUTION:

• The AMB cannot be isolated.

• If only one switching fabric module is working on the switch, it cannot be isolated.

• Before upgrading a logic of the line card, keep the line card offline.

• No other commands but the test diag-offline command can be executed for an isolated card.

Otherwise, the configuration cannot take effect.

Page 83

NOTE:

• Use the display device command to view whether a card is isolated, or, whether the card is in the offline

state.

• To minimize the interference on the system operation, force a switching fabric module that is operatin

normally offline before you unplug it.

• When you execute the test diag-offline command, the path where the fault detection information is

saved is also displayed following the fault detection

information on the terminal. For example, you can

see flash:/diag_slot3_20080522_103458.txt.

• Deliver the fault detection information to the H3C technical engineers or engineers of the sales agent.

Configuring in-service hardware failure diagnosis and failure protection

A hardware failure may cause traffic forwarding failures and service interruption. To improve the automatic failure detection and handling capabilities of the switch, you can configure in-service hardware failure diagnosis and failure protection.

The in-service hardware failure diagnosis and failure protection feature covers:

• In-service hardware failure detection for chips, cards, and the forwarding service, and automatic fix

actions taken for the detected failures.

• Failure protection for ports: When a hardware failure is detected on a port, the switch automatically

shuts down the port.

• Failure protection for aggregation groups. When a hardware failure is detected on a member port

of an aggregation group, if the member port is configured with the hardware-failure-protection auto-down command, the port is shut down automatically; if the member port is not configured with

that command but it is not the last up port in the aggregation group, the port is also shut down automatically; if the member port is not configured with that command and it is the last UP port in the aggregation group, the port will not be shut down.

Follow these steps to configure in-service hardware failure diagnosis and failure protection:

To do… Use the command… Remarks

Enter system view system-view —

Page 84

To do… Use the command… Remarks

Enable in-service hardware failure detection and configure fix actions taken in case of hardware failures

Required The fix actions taken in case of

hardware failures include the following ones:

• off: Takes no action.

• warning: Sends warning

messages.

• reset: Resets the failed card.

• isolate: Shuts down the failed

port, isolates the failed card, prohibits the failed card from loaded, or powers off the failed card to reduce the impact of the failure to the system.

By default, the fix action taken for all hardware failures is isolate.

Enable hardware failure protection for aggregation groups

Optional Disabled by default This command is effective only

when the fix action is configured as isolate.

Enter Ethernet interface view

Configure hardware failure protection for the port

hardware-failure-protection auto-down

Optional Disabled by default This command is effective only

when the fix action is configured as isolate.

CAUTION:

Before configuring the hardware-failure-protection auto-down

command on a port, make sure a backup

link exists to avoid service interruption in case the port is shut down.

The hardware-failure-protection aggregation and hardware-failure-protection auto-down command do not take effect on a port in either of the following cases:

• The port is configured with the loopback { external | internal } command.

• The port is configured with the port up-mode command.

NOTE:

• If a port is automatically shut down due to hardware failure protection, its status displayed with the

display interface command is Protect DOWN. To bring up the port, use the undo shutdown command on the port.

• If a card is isolated or its software is not allowed to be loaded due to hardware failure fix operations,

you can plug out the card and then plug it in to recover the card status.

• After configuring in-service diagnosis and failure protection, you can use the display

hardware-failure-detection command to check the running information of the feature.

Troubleshooting

This chapter describes how to troubleshoot the S12500 switch installation failures.

The power supply system, fans, and cards of an S12500 switch have multiple LEDs, through which you can locate the failures.

Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays booting information when the switch is powered on. If the setup is incorrect, the configuration terminal displays nothing or garbled text.

No terminal display

If the configuration terminal displays nothing after the switch is powered on, verify the following items:

• The power supply system works properly.

• The main processing unit (MPU) works properly.

• The console cable has been connected to the console port of the MPU.

If no problem is found, the following reasons may apply:

• The console cable is connected to an incorrect serial port (in other words, 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. If the cable fails, you can replace a cable.

Garbled terminal display

If terminal display is garbled, check that the following settings are configured for the terminal, for example, HyperTerminal:

• Baud rate—9,600

• Data bits—8

• Parity—none

• Stop bits—1

• Flow control—None

• Emulation—VT100

When the input/output LEDs are off or the fault LEDs are on, the power module does not work properly. To troubleshoot the power supply system:

1. Check the power cable connections. If a power cable is loose, re-plug the power cable.

2. Replace the power cable, and check whether the LEDs are normal.

3. Check the power module installation. If the power module is not fully seated, re-install the power

module to make sure it makes close contact with the backplane of the switch.

4. Check the power source. Make sure that the power source works properly and provides a normal

voltage.

5. Check whether the power module has encountered output short circuit, output over-current, output

over-voltage, input under-voltage, or over-temperature problems.

6. Plug the power module into an empty power module slot, and check whether the power module

can work properly. If the power module can work properly, the power module slot may have failed. Otherwise, proceed with the next step.

7. Plug a new power module that can work properly into the same power module slot, and connect

it to the same power source. If the new power module can work properly, the old power module fails. Contact the agents to replace the old power module.

When the MPU works properly, the RUN LED (callout 7 in Figure 55) flashes in green. When the RUN LED is off, steady on, or flashes in red, the MPU fails.

To troubleshoot the MPU:

1. Check that the power module works properly. For more information, see “Power supply system

failure.”

2. Press the RESET button of the MPU to reset the MPU. After the MPU is reset, check whether the

corresponding RUN LED flashes green.

3. Check whether the MPU is fully seated. You can unplug the MPU, plug it again, and make sure that

the MPU is fully seated.

4. If the switch has empty MPU slots, plug the MPU into an empty MPU slot, and check that the MPU

can work properly.

5. If the failure still exists, contact the local agents or technical support engineers.

LPU failure

When the LPU works properly, the LC LED (callout 3 in Figure 55) flashes, and the RUN LED on the LPU flashes in green.

When the two LEDs are not in the states mentioned above, the LPU fails.

To troubleshoot the LPU:

1. Check that the MPU works properly. For more information, see “MPU failure.”

2. Use the display device command to check whether the software version is compatible with the LPU

in the current slot. If the software version is incompatible with the LPU, upgrade the software to a compatible version.

3. Calculate the overall power consumption, and make sure that your power module can provide

enough power.

4. Check whether the LPU is fully seated. You can unplug the LPU, plug it again, and make sure that

the LPU is fully seated.

5. If the switch has empty LPU slots, plug the LPU into an empty slot, and check whether the LPU can

work properly.

6. If the failure still exists, contact the local agents or technical support engineers.

Page 97

When the two LEDs are not in the states mentioned above, the switching fabric module fails.

To troubleshoot the switching fabric module:

1. Check that the MPU works properly. For more information, see “MPU failure.”

2. Use the display device command to check whether the software version is compatible with the

switching fabric module in the current slot. If the software version is incompatible with the switching fabric module, upgrade the software to a compatible version.

3. Calculate the overall power consumption, and make sure that your power module can provide

enough power.

4. Check whether the switching fabric module is fully seated. You can unplug the switching fabric

module, plug it again, and make sure that the switching fabric module is fully seated.

5. If the switch has empty switching fabric module slots, plug the switching fabric module into an

empty slot, and check whether the switching fabric module can work properly.

6. If the failure still exists, contact the local agents or technical support engineers.

Interface failure

Both the MPU and LPU provide the LINK LEDs indicating the interface status. When the link of an interface is present and works properly, the corresponding LINK LED is on.

If the LINK LED of an interface is off, the interface or the connecting cable may fail.

To troubleshoot the interface:

1. Check that the MPU or LPU where the interface resides works properly. For more information, see

“MPU failure” o

r “LPU failure.”

2. Check the cable connection of the interface. For how to correctly connect the cable to an Ethernet

interface with an RJ-45 connector or an optical interface, see the chapter “Connecting your switch to the network.”

3. Check whether the cable is broken. Use the cable to connect two interfaces of the same type that

work properly. If the LEDs of the two interfaces are on, the cable is normal. Otherwise, the cable fails. Use a compliant cable to connect the interface.

4. If the interface uses a transceiver module, check that the interface type is compatible with the

transceiver module and that the transceiver module is compatible with the cable. For more information, see the chapter “Appendix C Transceiver modules.”

5. If the interface uses a transceiver module, make sure that the current transceiver module works

properly by replacing a normal transceiver module.

6. Use the display interface command to check whether the interface is UP. If the interface is not UP,

use the undo shutdown command to bring up the interface.

7. Check that the speed and duplex settings of the interfaces of a link are the same. Make sure that

two interfaces can work together.

8. If the failure still exists, contact the local agents or technical support engineers.

NOTE:

When an interface fails, if the switch has an idle interface of the same type, you can plu

the cable into the

idle interface.
