Interpreting POST results
POST is a system check that is performed each time the switch is powered on, rebooted, or reset.
During POST, the LEDs flash either amber or green. Any errors that occur during POST are listed in
the error log.
Complete the following steps to determine whether POST completed successfully and whether any
errors were detected.
1. Verify that the switch LEDs indicate that all components are healthy.
Refer to LED patterns on page 31 for descriptions and interpretations of LED patterns. If one or
more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to "beacon"
by entering the switchShow command to detect if beaconing is active.
2. Verify that the switch prompt displays on the terminal of a computer workstation connected to the
switch.
If there is no switch prompt when POST completes, press Enter . If the switch prompt still does not
display, try opening a Telnet session or accessing the switch through another management tool. If
this is not successful, the switch did not successfully complete POST. Contact your switch supplier
for repair.
3. Review the switch error log for errors. Any errors detected during POST are written to the error log,
accessible through the errShow command.
For information about all referenced commands, and on accessing the error log, refer to the Fabric
OS Administrator’s Guide . For information about error messages, refer to the Fabric OS Message
Reference Manual .
Brocade 6505 maintenance
The Brocade 6505 is designed for high availability and low failure; it does not require any regular
physical maintenance. Maintenance includes running diagnostic tests and checking and replacing
field-replaceable units, described in the following sections.
Installing an SFP+ transceiver
The Brocade 6505 only supports Brocade-branded 8 Gbps and 16 Gbps SFP+ optical transceivers.
For the Fibre Channel connections, the Brocade 6505 uses SFP+ transceivers that support any
combination of Short Wavelength (SWL), Long Wavelength (LWL), and Extended Long Wavelength
(ELWL) optical media.
If you use an unqualified transceiver, the switchShow command output shows the port in a Mod_Inv
state. Fabric OS also logs the issue in the system error log.
Complete the following steps to install an SFP+ transceiver.
1. Making sure that the bail (wire handle) is in the unlocked position, position the optical transceiver so
that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated
and the latching mechanism clicks; then close the bail.
The 16 Gbps SFP+ transceivers do not have bails. Use the pull tab on the 16 Gbps SFP+
transceivers to help push the transceiver into the port. Do not push too hard on the tab itself
becasue it can bend.
