To check and/or update the firmware version of a single device, use Customer Center:
Note that if there are any firmware policies set up in Control Center that apply to this device, those policies will override any changes you make to the device directly.
Use these instructions only for single device firmware operations and troubleshooting purposes. Applying the same firmware to more than one device should be done through Control Center. See Apply New Firmware to Devices.
Go through your company's service administrator/super user if you don't have access to our support portal yourself.
