Ax Controller - Mitel 3300 Technician's Handbook

AX Controller

To add or replace controller modules in AX front panel
1. Remove the blanking plate (or the old MMC) from the controller by
removing the screws that hold the standoffs to the controller. (The
screws are on the back side of the controller card.)
2. Back off the controller faceplate screw nearest the MMC slot a couple
of turns (because the screw interferes with the removal/insertion of
T1/E1, Quad BRI, Quad CIM, or Dual FIM modules).
3. Slide the blanking plate out of the opening from the back of the
controller faceplate.
4. Remove the two standoffs (closest to the face plate) from the blanking
plate (or old MMC). Retain the standoffs and screws.
5. Fasten the standoffs to the front of the new MMC.
6. Carefully slide the MMC face plate under the lip of the controller face
plate. See Figure 38. Do not push the MMC past the controller face
plate as shown in Figure 39.
7. Re-install and/or retighten screws.
8. Continue with procedure as described in the specific FRU instructions
