Replacing Mitel ASU Lite, Mitel ASU-II or Mitel ASU-III

The Mitel Server Unit, Mitel ASU Lite, Mitel ASU-II or Mitel ASU-III should only be replaced as a last measure when it is not operational, for example, due to some hardware failure.

Before replacing the server a test should be done to reinstall the software from Safety Backup or from the Recovery Image.

Also, in BIOS mode, see if the disk or disks are detected or not.

Warning: Do not change any BIOS settings!

In case of disk malfunction or uncertainty of its state, it is necessary to install the OS on the new unit to ensure that it runs on the same software as the rest of the system.

A new license file is needed when the ASU for LIM 1 will be replaced, because the hardware identity will be changed when a replacement ASU board is used. This will result in an alarm 117.

In a running system, a keyboard and monitor may be connected to a software switch where the user can select to which MX-ONE Service Node the I/O equipment is connected.
