Parameters

Name	Meaning
OID	Indicates the ID of the MIB object.
APMAC	Indicates the MAC address of an AP.
APName	Indicates the AP name.
ApIfIndex	Indicates the index of the AP interface on which the optical module is installed. This alarm is not supported by the AP8030DN, AP9131DN, AP9132DN, or AP6510DN among APs supporting optical modules.
Ap Optical RxPower	Indicates the current receive power of the AP's optical module.
ApEntityPhysicalName	Indicates the name of the AP interface on which the optical module is installed. This alarm is not supported by the AP8030DN, AP9131DN, AP9132DN, or AP6510DN among APs supporting optical modules.
APID	Indicates the AP ID.

Impact on the System

Services on the optical module are adversely affected, which probably leads to error codes, error packets, or even service interruption.

This alarm applies to Huawei certified optical modules only. For non-Huawei-certified optical modules, incorrect alarms may be generated.

Possible Causes

The receive power of the AP's optical module is lower than the lower power threshold.

Procedure

Check whether the type of the peer optical module matches that of the local optical module. For detailed matching rules, see Hardware Failures > Interface Faults > An Optical Interface Cannot Turn Up in the Hardware Installation and Maintenance Guide of the corresponding AP model.
- If so, go to Step 3.
- If not, go to Step 2.
Replace the peer optical module with one matching the type of the local one. Then, check whether the alarm persists.
- If so, go to Step 3.
- If not, go to Step 6.
Check whether the optical module is a Huawei certified optical module.
- If so, go to Step 5.
- If not, go to Step 4.
Replace the optical module with a Huawei certified optical module. Then, check whether the alarm persists.
- If so, go to Step 5.
- If not, go to Step 6.
Collect alarm messages, log messages, and configurations, and then contact the technical support personnel.
End.
