Firmware download issues
5
Symptom The blade is faulty (issue slotShow to confirm).
Probable cause and recommended action
If the port or application blade is faulty, enter the slotPowerOff and slotPowerOn commands for the
port or application blade. If the port or application blade still appears to be faulty, remove it and
re-insert it into the chassis.
Symptom The AP blade is stuck in the “LOADING” state (issue slotShow to confirm).
Probable cause and recommended action
If the blade remains in the loading state for a significant period of time, the firmware download will
time out. Remove the blade and re-insert it. When it boots up, autoleveling will be triggered and the
firmware download will be attempted again.
Firmware download issues
CAUTION
After you start the firmware download process, do not enter any disruptive commands (such as
reboot) that will interrupt the process. The entire firmware download and commit process takes
approximately 17 minutes.
If there is a problem, wait for the time-out (30 minutes for network problems) before issuing the
firmwareDownload command again. Disrupting the process can render the switch inoperable and
require you to seek help from your switch service provider.
Do not disconnect the switch from power during the process because the switch could become
inoperable when rebooted.
The following symptoms describe common firmware download issues and their recommended
actions.
Symptom The firmwareDownload command and subsequent POST failure may occur on the Brocade AP
blades FR4-18i, FA4-18, FC4-16IP, and the Brocade 7500 and 7600 switches when the
firmwareCommit operation coincides with the execution of POST.
Probable cause and recommended action
The BP is too busy during the firmwareDownload and firmwareCommit operations which happens
at the same time when POST is executed.
The recommended work around is to disable POST using the diagDisablePost command before you
initiate the firmwareDownload command and re-enable POST using the diagEnablePost command
after the firmwareCommit is complete.
