SP 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 “Service position procedures” on page 3-9 for placing a switch into the service position or
for removing the switch from the service position.
Step 0600-001
You have arrived at this MAP from Table 1-1 on page 1-4.
1. Perspectives reports “Warning”, “Shutdown”, or “Failure” message associated with SP Switch.
2. Does message indicate “Shutdown” or “Failure”?
v
If yes, go to “Step 0600-003”.
v
No, the message indicates a “Warning”, go to “Step 0600-002”.
Step 0600-002
You received a switch environment “Warning”.
1. Does this same message occur on other SP Switches or on any processor nodes mounted in the
same frame as the switch?
v
If yes, call the next level of support.
v
If no, verify that the customer is not experiencing problems with this SP 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, service can be performed now by returning to “Step
0600-001” and treating this message as a “Shutdown” or “Failure” message.
Step 0600-003
A Perspectives message indicates a “Shutdown” or “Failure”. This means that a serious environmental
condition has been detected in the SP Switch.
Note: If service action has just been completed on this SP Switch, check for loose cables or shorted
conditions in this component.
