Cisco 5520 and 8540 Wireless Controller Troubleshooting Guide
Setting up CIMC
Note Default password will be either ‘password’ or ‘Cisco1234’. You can change this via the username
command
CIMC Configurations that are required for reliable WLC operation
Note Once the user logs in to CIMC the following should not be changed. This will cause issues for WLC
operation.
• Do not change the NIC mode to shared. It should be in dedicated mode
• Do not change the FlexFlash Mode
• Do not change the SSD/Virtual disk settings
• BIOS parameters should not be changed
Expectations when logged in via CIMC
• FlexFlash is configured for RAID but only one flash is populated this causes CIMC to show the
FlexFlash as degraded.We can safely dis-regard the FlexFlash degradation warning in our case.
• Expect to see only one CPU populated
• Do not configure Software Raid on SSD
