Maintenance Approach - HP StorageWorks Edge Switch 2/12 Service Manual

Maintenance Approach

Whenever possible, the maintenance approach instructs service personnel to
perform fault isolation and repair procedures without degrading or interrupting
operation of the switch, attached devices, or associated applications.
Switch fault isolation begins when one or more of the following occur:
System events can be related to a:
Fault isolation and service procedures vary depending on the system event
information provided. Fault isolation and related service information are provided
through maintenance analysis procedures (MAPs) documented in Chapter 3.
MAPs consist of step-by-step procedures that prompt service personnel for
information or describe a specific action to be performed.
MAPs provide information to interpret system event information, isolate a switch
failure to a single FRU, remove and replace the failed FRU, and verify switch
operation. The fault isolation process normally begins with
MAP" on page 32.
Before using these procedures, ensure the correct switch is selected for service by
enabling unit beaconing at the failed switch. The amber system error (ERR) LED
on the switch front panel blinks when beaconing is enabled. Instructions to enable
beaconing are incorporated into MAP steps.
