Chapter 71 Performing Diagnostics
The message indicates that the line card passed online diagnostics either when it was inserted into the
chassis the last time or when the switch was powered up (as reported by the “.”). You need to obtain
additional information to determine the cause.
Step 2 Insert a different supervisor engine card and reinsert the line card.
If the line card passes the test, it suggests that the supervisor engine card is defective.
Issue an RMA for the supervisor engine, contact TAC, and skip step 3.
Because online diagnostics are not run on the supervisor engine card, you cannot use the
#show diagnostic module 1 command to test whether the supervisor engine card is faulty.
Step 3 Reinsert the line card in a different chassis.
If the line card passes the test, the problem is associated with the chassis.
Issue an RMA for the chassis and contact TAC.
Power-On Self-Test Diagnostics
The following topics are discussed:
• Overview of Power-On Self-Test Diagnostics, page 71-10

• Power-On Self-Test Results, page 71-13
• Troubleshooting the Test Failures, page 71-20
Overview of Power-On Self-Test Diagnostics
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 the supervisor switching
engine, its associated packet memory and other on-board hardware components. The results of the POST
impacts how the switch boots, because 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
