Hi,
I'm planing to upgrade a WLC (AIR-CT5520-K9) from 8.2.166 to 8.10.162.
I read that it's better to do it from 8.2->8.5->8.10 and also an upgrade of the CIMC firmware is required. However, I have no information of the CIMC connected to my WLC. Is it possible that it does not have one? Is there anyway to find out the CIMC IP from the WLC? (imm is configured with DHCP)
(Cisco Controller) >show sysinfo
Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Product Version.................................. 8.2.166.0
RTOS Version..................................... 8.2.166.0
Bootloader Version............................... 8.3.15.177
Emergency Image Version.......................... 8.2.166.0
(Cisco Controller) >imm summary
This will take some time...
Please be patient!
User ID.......................................... admin
DHCP............................................. Enabled
IP Address....................................... 0.0.0.0
Subnet Mask...................................... 0.0.0.0
Gateway.......................................... 0.0.0.0
Any help would be greatly appreciated. Thanks!

Thanks for your responses, but my question is more about how to find the CIMC information itself. Don't know if there is one or not.
Is it possible that it does not have one? Is there anyway to find out the CIMC IP from the WLC? (imm is configured with DHCP)

- From your original post it seems as it did not acquire an IP , set it manually as being explained in the link I posted, connect to it afterwards and follow the procedures accordingly and or check the current firmware version.

Actually @Leo Laohoo CIMC should be done even if you aren't using it because the update package also includes a number of firmware fixes for critical bugs as per https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn810mr6.html#cimc-upgrade
In answer to your other question @anthony.harden yes they always have a CIMC because CIMC is a standard part of the Cisco UCS servers these are built on.
