IDU Replacement

There are two situations, which must be treated differently.
Situation 1:
To replace either of the IDUs at Site 1.4 or the IDU at Site 2.2, nothing special is required.
Simply disconnect the IDU to be replaced – and replace it with a new one. Replacing a sec-
ondary link IDU obviously has no effect on the TDM service. Disconnecting the Site 1.4 pri-
mary IDU activates Hot Standby. After the Site 1.4 primary IDU is replaced, the Link will
detect the change and switch back to the primary link.
If you replaced the Site 2.2 IDU, remember to reconnect the MHS cable.
Situation 2:
Replacing the Site 1.2 IDU is different, and requires several steps.

To replace the Site 1.2 primary link IDU:
1. Power off the Site 1.2 IDU. This activates the secondary link using Hot Standby.
