Switch environment (MAP 0600)

Switch environment (MAP 0600)

Purpose of this MAP

This MAP provides diagnostic information for switch problems that are related to the operating environment.

Note: Refer to ªService position proceduresº on page 3-10 for placing a switch into the service position or for removing the switch from the service position.

Step 0600-001

A switch environmental problem has been detected.

1. You have observed either:

vThe yellow switch supervisor LED is on or flashing

vPerspectives switch environmental indicator is yellow or red

vErrpt message stating,ªWarningº, ªShutdownº, or ªFailureº

2.If:

vThe yellow switch supervisor LED is on, or the Perspectives environmental indicator is yellow, or the Errpt message states ªWarningº, go to ªStep 0600-002º.

vThe yellow switch supervisor LED is flashing, or the Perspectives environmental indicator is red, or the Errpt message states ªShutdownº or ªFailureº, go to ªStep 0600-003º.

Step 0600-002

You received a switch environment ªWarningº.

1.Does this same message occur on other switches or on any processor nodes mounted in the same frame as this switch?

v If yes, call the next level of support.

vIf no, verify that the customer is not experiencing problems with this switch.

±If no problems are being experienced, or this is an N+1 fan or power supply failure, then no immediate service is required, and service can be deferred until a later date.

±If problems are being experienced, and the customer will allow power on service, service can be performed now by treating the problem as an Errpt message of ªShutdownº or ªFailureº and going to ªStep 0600-003º.

Step 0600-003

A critical power or environmental problem has been detected and the switch has logically powered off.

1.If service action has just been completed on this switch, check for loose cables or shorted conditions.

2.Record the locations of all failing FRUs (multiple FRUs may be reported).

Note: Fans are N+1 devices; two fans off will power off the SP Switch2. Power Supplies are N+2; three power supplies off will power off the SP Switch2. Therefore, fix all fan problems before troubleshooting power supply problems.

3.Power off the switch using the rear 48 V circuit breaker. Remember to turn on the circuit breaker when the repair has been completed.

4.Based on the text of the message, use the information in Table 1-3to continue service.
