13.3 Mount Telephony Gateway to Wall

Like the MCU, the OAI Telephony Gateway is designed to be mounted on a backboard
of ¾ inch plywood, securely fastened to the wall. Mount the Telephony Gateway
vertically, adjacent to the last MCU. Do not stack the MCUs or Telephony Gateway on
top of one another.

To mount the OAI Telephony Gateway:

1. Using a 1/8” drill bit, drill four pilot holes, on 2 inch by 12.1 inch centers.

2. In each pilot hole, sandwich a star washer between the ESD bonding strap and the

backboard, then insert the screw (#8 panhead wood screw, 3/4 inch long) and
tighten it, leaving approximately 1/8 to ¼ inch gap from the wall.

3. Slide the Telephony Gateway over the screw until it drops in place.

4. Tighten screws fully.
