Reliability, Availability, and Serviceability

Both the PXM45 and the PXM1E support the following reliability, availability, and serviceability (RAS) features:

•Power On Self Test (POST)

•Hardware Monitoring Module (HMM)

•Online diagnostics

•Offline diagnostics

•Enhanced alarm reporting

The POST and HMM features are transparent to the user. However, the dsppostresults command can be used to display the POST results. POSTs are a set of tests that run at boot-up time. POSTS cannot be disabled.

Diagnostics

Diagnostics commands can be used to isolate or troubleshoot problems. The following procedure shows the steps for identifying problems or failures:

Step 1 Observe card alarms.

MGX8850.7.PXM.a>dspndalms

Step 2 Observe hardware or diagnostic alarms and slot numbers

MGX8850.7.PXM.a>dspcdalms

Step 3 If there are hardware alarms, change card to appropriate slot .

MGX8850.7.PXM.a>cc slot

Step 4 Display alarms to identify the device.

MGX8850.7.PXM.a>dsphwalms

Step 5 Display errors on device.

MGX8850.7.PXM.a>dspdeverr device

Step 6 If there are diagnostic alarms, change card to appropriate slot

MGX8850.7.PXM.a>cc slot

Step 7 Display diagnostics results.

MGX8850.7.PXM.a>dspdiagresults

Table G-1 shows some of the other commands that can be used to isolate and troubleshoot problems. For details about these commands refer to the Cisco MGX 8850 (PXM45/PXM1E), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Command Reference, Release 5.
