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
times out. Remove the blade and re-insert it. When it boots up, autoleveling is triggered and the
firmware download is attempted again.

Firmware download issues

CAUTION
After you start the firmware download process, do not enter any disruptive commands (such as
reboot) that interrupts 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 Firmware download times out.
Probable cause and recommended action
This can be caused by an excessively slow network. If it takes more than 30 minutes to download
firmware on a switch, or on each CP in a director, the firmware download process times out. If a
timeout occurs on a switch, the firmware download process synchronizes the two partitions on the
switch by starting a firmware commit operation. If a timeout occurs in a director, the firmware
download process synchronizes the firmware on the two partitions on the CP blades by starting a
firmware commit operation on each CP.
Wait at least 15 minutes for the commit operation to complete then use the firmwareShow
command to verify the partitions are synchronized. In some older versions of firmware, the
firmware commit operation may not be started automatically on the switch (or on the standby CP in
director). In this case, you can enter the firmwareCommit command manually on the switch (or on
the standby CP in director) to synchronize the partitions. After the firmware commit operation
completes, reissue the firmwareDownload command to upgrade the system.
