Analog Main Board

MXe

To replace the analog main board (AMB) in an MXe:
1. Remove the narrow flex cable on the AMB (J4) by flipping up the clip
on the connectors at each end of the cable (prior to Rel 7.1 version)
or remove the ribbon cable on the AMB (J8) (see Figure 41).
Tip: A replacement AMB ships with a connector-less flex cable that you will
discard for the MXe controller.
2. Loosen the captive screw on the AMB.
3. Remove the AMB.
4. If you are replacing the AMB with an AMBv3, the replacement kit will
include a new label that identifies the protected ports.
• If your MXe still has the old AMB label, apply the new label over the
existing one.
• If your MXe has the new AMB label, discard the label.
5. Place the new AMB on the power supply carrier and slide the port
interfaces through the slots at the rear of the controller.
6. Secure the AMB to the carrier with the captive screw provided.
7. AMB 2: Attach the connector-less flex cable to the controller by lifting
up the clip and inserting the cable vertically into the connector. Push
the clip down to secure the cable.
8. AMB 3: Attach the ribbon cable to the controller and the AMB.
