1. Verify that the LEDs on the switch indicate that all components are healthy. (LED patterns
are described in
(page 53) and (page 54) .) If one or more LEDs do not display a healthy
state, do the following:
a.
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 Fabric OS Administrator's Guide or the Web Tools Administrator's
Guide .
b. Follow the recommended action for the observed LED behavior, as listed in Table 8 (page
53) and Table 9 (page 54) .
2. Verify that the switch prompt appears on the terminal of a computer workstation that is
connected to the switch.
If the prompt does not appear when POST completes, press Enter . If the prompt still does
not appear, open another Telnet session or access the switch through another management
tool. If this is not successful, the switch did not successfully complete POST. Contact the
switch supplier.
3. Using either Web Tools or the CLI, verify that the diagnostic status for all ports in the switch
is OK.
•
If you are using Web Tools, select Port Admin or Status to display information about
the ports.
•
If you are using the CLI, use the
diagshow
command.
4. Review the system log for errors.
•
If you are using Web Tools, errors are listed under Switch Events .
•
If you are using the CLI, 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 Message Reference .
Maintaining the 8-Gb SAN Switches
The 8-Gb SAN Switches are designed for high availability and low failure. They do not require
any regular physical maintenance. They include diagnostic tests and FRUs for the 8/40, 8/80,
Encryption SAN Switch, FCoE Converged Network Switch, and 1606 Extension SAN Switch, as
described in the following sections.
Installing an SFP
The 8-Gb SAN Switches support only HPE-branded SFPs. For ordering information, see Supported
SFP transceiver options (page 21) .
If you use an unqualified SFP, the
switchshow
command output will show the port in an
Mod_Inv
state. Additionally, the firmware logs the issue in the system error log.
To install an SFP:
1. Verify that the bale (wire handle) is in the unlocked position (see Figure 34 (page 65) ).
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 bale.
