3 Board Loading Troubleshooting
3.1 Board Loading Overview
This section describes the knowledge you need to know before troubleshooting board loading.
Loading is an important module in the device management. Through board loading, system and
logical software can be downloaded from the CF card of the Master Control Unit to the storage
area of the LPU.
The storage area of the LPU falls into two categories:
l
BootROM
l
Logical chip
The types of the loaded software on different hardware are different, including:
l
BIOS, EPLD ( Erasable Programmable Logic Device ) for LPU
There are three ways to load the software:
l
Start-up loading: After the main system started, the board downloads the software to the
storage area of the relevant board according to the hardware type. The whole process
completes automatically. The loading files vary with board types, so the S9300 identifies
the loading files with different IDs.
l
On-line loading: It is also called force-loading and indicates that the relevant software
(except EPLD) or logical file is loaded to the board by the command line.
3.2 Troubleshooting Board Loading
This section presents the flowchart and procedure of board loading troubleshooting.

4 Board Registration Troubleshooting
Quidway S9300 Terabit Routing Switch
Troubleshooting - Device Management
4.1 Board Registration Overview
This section describes the knowledge you need to know before troubleshooting board
registration.
Registration is a key part of device management. Registration indicates that the active Master
Control Unit manages the board after all hardware and software are initialized on the board
without any problems and the state of the board is reported to the active Master Control Unit.
In the registration process, the board needs to interact with the Master Control Unit.
Processing of the LPU
1.
Sends the registration request to the Master Control Unit. The request contains the version
and initialization self-check information of each module.
2.
Exits registration after receiving the registration response.
Processing of the Master Control Unit
1.
Receives the registration request from the LPU and check the self-check information.
2.
If the self-check information is correct, records the LPU information and sends a response
to the LPU. If the self-check information is incorrect, resets the LPU and records the
resetting reason in log and reports the alarm.
4.2 Troubleshooting Board Registration
This section describes the procedure for board registration troubleshooting.
CAUTION
Do not draw out the board or reset the board when the bootrom program or bootload program
is loading on the LPU; otherwise, the program will be damaged, and you should contact Huawei
engineers to repair it.

4.2.2 Troubleshooting Procedure
Procedure
Step 1 Check whether the board is not registered within the start-up time. If it is still within the startup time, wait until the start-up time does not expire.
Start-up time refers to a period from the board power-on to registration. The start-up time of
each type of board is as follows:
l
The start-up time of the Master Control Unit is within three minutes. If the S9300 is restarted
after system upgrade, the start-up time is within five minutes.
l
The start-up time of the LPU is within five minutes. If the system software is upgraded, the
start-up time is within 10 minutes.
Step 2 Check whether the board start-up failure is caused by board registration fault.
l
Check whether the board registration fails. If it is a board registration fault, remove the fault
by referring to "3 Board Loading Troubleshooting".
l
Run the display device command to check the board status.
Step 3 Find the reasons for board resetting by commands.
If the board does not complete the registration beyond the startup time, process it as follows:
Running the display logbuffer slot slot-id command, you can check reasons for board resetting,
and then locate the faults according to the fault cause.
<Quidway> display logbuffer slot 5

5.1 CF Card Overview
This section describes the knowledge you need to know before troubleshooting the CF card.
CAUTION
The compact flash (CF) card on the panel of the Master Control Unit does not support hot swap.
The S9300 has one CF card, which is installed on the panel of the Master Control Unit. The CF
card stores system file, configuration file, PAF, license file, and log files.
The log files of the S9300 are stored in the CF card, so the storage space of the CF card may be
full when the S9300 operates for a long time. In this case, the S9300 deletes the log files by
generation date. The earliest log file is deleted first. To save the log files, you can transfer the
files through FTP or TFTP, and then delete the files from the CF card.

This section provides an introduction to the PoE power.
6.1.1 Introduction to PoE
6.1.2 Power-on Process of PoE
6.1.3 PoE Working Mode Supported by theS9300
6.1.1 Introduction to PoE
Power over Ethernet (PoE) involves the power sourcing equipment (PSE) and the power device
(PD). The PoE technology is used on the wired Ethernet and is most widely used on local area
networks (LANs). This technology transmits power coupled with data to terminals through
cables or transmits power without data through idle lines. The S9300 transmits power coupled
with data at a rate of 1000 Gbit/s.
Currently, the S9300 V100R001 does not support the PoE feature, and the S9300 V100R002
supports this feature.
6.1.2 Power-on Process of PoE
This section describes the standard power-on process of PoE. The S9300 can automatically
complete steps 1, 2, 4, and 5. Step 3 can be performed automatically or manually and the actual
operation varies in the two modes:
l
In automatic mode, you do not need to perform any operation.
l
In manual mode, you need to run certain commands to complete the operation.
The PSE powers on a PD as follows:
1.
Detection: The PSE detects whether the PD exists.
The PSE detects whether the PD exists by detecting the capacitive resistance between
output power supply pairs. In the detection stage, the PSE provides certain voltage, and
then calculates the feature resistance of the PD based on the returned current. The PSE
proceeds to the next step only if the feature resistance of the PD is within the valid range.
2.
Classification: The PSE determines the power consumption of the PD.
The PSE determines the power level of the PD according to the output current. In the
classification stage, the port connected to the PD provides certain voltage, and then
calculates the power range according to the returned current.
3.
Power-on: The PSE provides power for the PD.
When detecting that the downstream device connected to the port is a valid PD and
classifying the PD, the PSE provides -48 V power for the PD.
6-2
4.
RTP & Power management: The PSE provides functions of over-current protection,
current/voltage detection, short-circuit protection, open-circuit protection, and
troubleshooting.
5.
Disconnection: The PSE detects whether the PD is disconnected.

Issue 02 (2009-09-30)
Quidway S9300 Terabit Routing Switch
Troubleshooting - Device Management
6 POE Troubleshooting
The PSE detects whether the PD is disconnected by using a special detection method. If
the PD is disconnected, the PSE shuts down the port to stop providing the voltage. The port
then enters the detection state.
6.1.3 PoE Working Mode Supported by theS9300
Automatic Mode
In automatic mode, the PSE automatically detects, classifies, and powers on PDs. If no valid PD
is detected on a port, the PSE repeats the detection step until it detects a valid PD.
Manual Mode
In manual mode, the PSE automatically detects and classifies PDs but does not power on PDs.
You need to run certain commands to power on PDs. To manually power on or power off PDs,
you must set the PoE working mode of the relevant board to manual mode in system mode.
Table 6-1 describes the commands that are used in manual mode.

This fault occurs usually because the PoE power supply does not provide power.
1.
1. Ensure that the PoE power supply is well connected.
2.
2. If the PoE power supply is well connected, ensure that the PoE power supply is powered
on and works normally.
Run the following command to view information about the PoE power supply in the
corresponding slot.
<Quidway> display poe-power
Available total POE power(mW) : 800000
System reserved POE power(mW) : 48000

Power value(mW) : 800000
Voltage value(V) : 53.57
Current value(A) : 0.24
If the PoE power supply works normally, it indicates that the fault lies in the DIMM. In
this case, you need to replace the DIMM. Remove the PoE board from the subrack, and
then replace the DIMM.
6.2.2 PSE Cannot Detect Any PD
Fault Symptom
After a PD is connected to a port of the S9300, this port keeps in Detecting state.
Fault Analysis
Theoretically, a port can automatically detect and classify a PD are the PD is connected. If the
power of the port is sufficient, the port can provide power for the PD automatically. If the power
of the port is insufficient, the port keeps in Classification completed state. If the port retains in
the Detecting state after a PD is connected, locate the fault as follows:
1.
Check whether the PD is an device according with 802.3af or 80.2.3at.
2.
Run the following command to view the status of each PoE port on the board.

If the fault cannot be located, contact Huawei technical personnel.
6.2.3 PSE Cannot Provide Power for PDs
Fault Symptom
After a PD is connected to a port of the S9300 through a network cable, the PD cannot be powered
on.
Fault Analysis
Theoretically, a port can automatically detect and classify a PD when the PD is connected to the
port. If the power of the port is sufficient, the port can provide power for the PD automatically.
If the power of the port is insufficient, the port keeps in Classification completed state. If the
port keeps in Classification completed state but cannot power on the PD, do as follows to locate
the fault:
1.
Run the following command to view the status of each PoE port on the board.

The Port reference power(mW) field indicates the reference power of the port. If this
port needs to power a PD, the available power of the board must be greater than or equal
to the reference power of the port.

The Port max power(mW) field indicates the maximum power of the port. If this port
needs to power a PD, the maximum power of the port must be greater than or equal to
the reference power of the port.
Run the following command to check the power supply information in the corresponding
slot.
<Quidway> display poe information slot 4
Codes: USMPW(User Set Max Power), AVTPW(Available Total Power),
TRPW(Total Reference Power), TPWC(Total Power Consumption),
PKVAL(Peak Value), PWMGM(Power-Management mode)

-------------------------------------------------------------------------------------------------------------------
(1) Check the value of AVTPW. If the value is 0, it indicates that the board does not
obtain power, and hence cannot provide power for the port.
(2) The value of PWMGM should be auto. If the value of PWMGM is manual, run the
poe power-on interface { interface-name | interface-type interface-num } command
in the system view to power on the port manually.
(3) Calculate the available power of the board by using the formula: Available power =
Min. (USMPW, AVTPW) – TPWC.
Compare the reference power of the port with the available power of the board. If the
reference power of the port is larger, it indicates that the available power of the board
is insufficient for the PD.
(4) 4. Run the following command to view information about the PoE power supplies.
Check whether at least one PoE power supply works normally.
<Quidway> display poe-power
Available total POE power(mW) : 800000

(5) 5. If at least one PoE power supply works normally, check the value of User reserved
POE power percent. If the value is 100, it indicates that all the power of the PoE
power supply is reserved, so the port cannot be powered on.

Some Ports May Fail to Be Powered on If the S9300 Is Not Grounded
Layout of network cables is uncontrollable, so network cables easily undergo interference of
signals, for example, from a large power base station. When the S9300 is not grounded, the
disturbance signals may affect the detection signals in network cables. As a result, the S9300
cannot detect PDs, and hence cannot power on the PDs.
PoE Function Is Unavailable on All Ports Due to Faults of PoE Power Supplies
When the S9300 Works Under Full Power
Assume that two 800 W PoE power supplies are installed on an S9312, so the total power of the
system is 1600 W. When the total power consumption of the S9300 exceeds 800 W and a PoE
power supply is faulty at this time, the system software cannot shut down PoE ports in time.
Therefore, the instant power is too large, causing over-load protection of the other PoE. Then
all PDs are powered off. After the PoE power recovers, the S9300 powers on the PoE ports
according to their priorities.
