Maintenance Approach - HP 316095-B21 - StorageWorks Edge Switch 2/24 Service Manual

General Information

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 one of the following:
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 33.
Before using these procedures, ensure the correct switch is selected for service (if
the HAFM server manages multiple switches or other HA Fabric Directors and
Edge Switches) by enabling unit beaconing at the failed switch. The amber system
error LED on the switch front panel blinks when beaconing is enabled.
Instructions to enable beaconing are incorporated into MAP steps.

System event information displays at the attached HAFM server, a remote
workstation communicating with the HAFM server, or the embedded web
server interface.
LEDs on the switch front panel or FRUs illuminate to indicate a hardware
malfunction.
An unsolicited SNMP trap message is received at a management workstation,
indicating an operational state change or failure.
Notification of a significant system event is received at a designated support
center through an e-mail message or the call-home feature.
Switch or HAFM server failure (hardware or software).
Ethernet LAN communication failure between the switch and HAFM server.
Link failure between a port and attached device.
ISL failure or segmentation of an E_Port.
