CAUTION:
Removing a powered CTM from the Reader rack can damage the
CTM. Before removing a CTM from the Reader, ensure that power
on the affected side of the Reader is turned off, i.e. the power
switch on the PSM is in the off position, or the PSM AC input
power cord is disconnected.
Removing a CTM
1. Switch the Reader over to the side with the CTM that is not being replaced (see Manually switching a
Reader to the redundant side, page 46).
2. Set the PSM powering the CTM being replaced to the off position.
3. Label and then disconnect any communication cables connected to the CTM.
4. Remove the faulty CTM from the Reader rack.
Installing a CTM
CAUTION:
To avoid damaging the modules, ensure that the connector on the
module is properly aligned with the connector on the DSM back
plane before the module is securely plugged into the DSM.
1. Install a new CTM in the Reader Rack.
2. Reconnect the communication cables to the CTM.
3. Set the PSM and CTM to the on position.
4. Switch the Reader to the new CTM side (see Manually switching a Reader to the redundant side, page
46).
5. If the CTM is in an IR network, reboot the CTM (see Rebooting the CTM, page 235).
