Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or reset, and
during which the LEDs flash different colors.
To determine if POST completed successfully and whether any errors were detected:
• Verify that the LEDs on the switch indicate that all components are healthy. (LED patterns are
described in
• Verify that the LEDs are not set to "beacon" (this can be determined through the switchShow
command or Web Tools). For information about how to turn beaconing on and off, see the HP
StorageWorks Fabric OS administrator guide or the Web Tools administrator's guide.
• Follow the recommended action for the observed LED behavior, as listed in
Table 1
• Verify that the diagShow command displays that the diagnostic status for all ports in the switch
is OK.
• Review the system log for errors. Errors detected during POST are written to the system log,
which is viewed using the errShow command. For more information about this command,
see the Fabric OS command reference manual. For information about specific error messages,
see the Fabric OS message reference manual.

Maintaining the 8Gb SAN Switch

The 8Gb SAN Switch is designed for high availability and low failure; it does not require any regular
physical maintenance. It includes diagnostic tests and field-replaceable units for the 8/40 and 8/80
SAN Switches, described in the following sections.

Installing an SFP

The 8Gb SAN Switch supports only HP-branded SFPs. See
for ordering information.
If you use an unqualified SFP, the switchShow command output will show the port in an Mod_Inv
state. Additionally, the firmware will also log the issue in the system error log.
To install an SFP:
1.
Verify that the bail (wire handle) is in the unlocked position (see
2.
Place the SFP in the correctly oriented position on the port.
NOTE:
Each SFP has a gold-plated PCB-edge connector on the bottom. The correct position to
insert an SFP into the upper row of ports is with the gold edge down. The correct position
to insert an SFP into the lower row of ports is with the gold edge up.
3.
Slide the SFP into the port until you feel it click into place; then close the bail.
