When installing or troubleshooting an AC41 it may be necessary to find the serial number or the MAC address of the controller.

The serial number and MAC address can be found on a sticker inside of the access controller's case. Open the door on the front of the AC41 and look for the sticker on the bottom right, directly under the cable management compartment.

If it has already checked into command in the past, you can find it from the devices page
