Chapter39 Diagnostics on the Catal yst 4500 Switch
1) linecard-online-diag --------------------> .
The linecard passed online diagnostics either 1) when it was inserted into the chassis the last time or 2)
when the switch was powered up (as reported by the "."). Further investigation is required.
Step2 Insert a different supervisor engine card and re-insert the linecard.
If the linecard passes the test, it suggests that the sup ervisor engine card is defective.
RMA the supervisor engine, contact TAC, and skip step 3.
Because online diagnostics is not run on the supervisor engine card(s), so you cannot use the
#show diagnostic module 1 command to test whether the supervisor engine card is faulty.
Step3 Re-insert the linecard in a different chassis.
If the linecard passes the test, the problem is associated with the chassis.
RMA the chassis and contact TAC.

Overview

All Catalyst 4500 series switches have power-on-self-test (POST) diagnostics that run whenever a
supervisor engine boots. POST tests the basic hardware functionality for th e supervisor switching
engine, its associated packet memory and other on board hardware components. The results of POST
impacts how the switch boots, as the health of the supervisor engine is critical to the operation of the
switch. The switch might boot in a marginal or faulty state.
POST is currently supported on the following supervisor engines:
•WS-X4014
•WS-X4515
•WS-X4516
•WS-X4516-10GE
•WS-X4013+
•WS-X4013+TS
•WS-X4013+10GE
•WS-C4948G
•WS-C4948G-10GE
The POST results are indicated with a '.' for Pass, an 'F' for Fail and a 'U' for Untested.
