EntPhysicalName	Indicates the name of the entity.
RelativeResource	Indicates the part related to the alarm.
ReasonDescription	Indicates the description of the alarm cause.

Impact on the System

The problematic board does not work, and services on the board are interrupted. If a PHY failure has occurred, the RUN indicator on the board is off, and the Alarm indicator is steady red.

Possible Causes

Cause 1:

Optical modules used on the board are non-Huawei-certified switch optical modules. This alarm may also be reported for early delivered Huawei optical modules because vendor information of these optical modules is not recorded.

Cause 2:

The link between the CPU and PCI bridge has failed. (PCI stands for Peripheral Component Interconnect.)

Cause 3:

The link between the CPU and forwarding module has failed.

Cause 4:

The field programmable gate array (FPGA) does not work normally.

Cause 5:

The network processor (NP) does not work normally.

Cause 6:

The phase-locked loop (PLL) is abnormal.

Cause 7:

The complex programmable logical device (CPLD) does not work normally.

Cause 8:

The link between the CPU and PCI-PCIe bridge has failed. (PCIe stands for Peripheral Component Interconnect Express.)

Cause 9:

Physical ports on the chip do not work normally.

Cause 10:

Fans do not work normally.

Cause 11:

The Centralized Monitoring Unit (CMU) of the switch does not work normally.

Cause 12:

An error occurs when operations are performed on the flash memory.

Cause 13:

The PHY layer does not work normally.

Cause 14:

The TCAM does not work normally.

Cause 15:

The RTC does not work normally.

Procedure

Rectify the fault based on the error code.

Error Code	Possible Causes and Impact on the System	Procedure
132610	The CMU does not match the device model, so the CMU does not work and the power supply units and fans may run abnormally.	Run the display device command to check device model information. Use a CMU that matches the device model. For the mappings between CMUs and device models, see the Hardware Query Tool.
132613	The serial gigabit media independent interface (SGMII) channel between the CPU and field programmable gate array (FPGA) on the card has failed. Packets cannot be sent to the CPU for processing.	Restart the faulty card and check whether the alarm persists. If the alarm is not cleared, replace the faulty card in the slot.
132625	The chip on the card has failed. If an LPU fails, all services running on the LPU may be interrupted. If the standby MPU fails, the system reliability will be affected. If the active MPU fails, an active/standby switchover will occur.	Restart the faulty card and check whether the alarm persists. If the alarm is not cleared, replace the faulty card in the slot.
132627	The card fails to register.	Restart the faulty card and check whether the alarm persists. If the alarm is not cleared, replace the faulty card in the slot.
	Run the power off slot slot-id command to power off the faulty card.	Check whether the operation is required by services. If so, this alarm is informational and no action is required. If not and the card is still required, run the power on slot slot-id command to power on the card.
	Run the reset slot slot-id command to reset the card.	This alarm is informational and no action is required.
132632	The Peripheral Component Interconnect (PCI) bus failed.	Restart the faulty card and check whether the alarm persists. If the alarm is not cleared, replace the faulty card in the slot.
132648	After you hold down the OFL button on the faulty card for 6 seconds, the card becomes unavailable and this alarm is generated. Services are not affected.	Wait until the OFL indicator on the card turns red, and then remove the card. If the card is not removed within 10 minutes, the card will be reset and go online again.
