IP Key Expansion Module (KEM) User Guide
Hot plug-in
Hot plug-in refers to the connection of one or more Avaya IP Deskphone KEMs to an active IP
Phone. When you connect an IP Phone KEM to an IP Phone that is already active, the IP Phone
does not need to be restarted. If there are other IP Phone KEMs already connected to the IP Phone,
all the IP Phone KEMs will reboot when you connect a new module.
Coldstart
You can press a sequence of keys (on the KEM) to trigger a cold start of a single Avaya IP
Deskphone KEM, or all Avaya IP Deskphone KEMs attached to the same IP Phone. The sequence
must be performed while the icons are flashing.
•
To coldstart a single Avaya IP Deskphone KEM, press the following sequence of keys: 0, 12,
22, 10.
•
To coldstart all attached Avaya IP Deskphone KEMs, press the following sequence of keys: 0,
12, 23, 11.
Figure 3
illustrates both coldstart sequences.
Note:
If you install two IP Phone KEMs on your IP Phone, the one directly attached to
the IP Phone (to the immediate right of the IP Phone) must be functional for the second
Avaya IP Deskphone KEM to operate. This is because the second Avaya IP Deskphone
KEM uses the first Avaya IP Deskphone KEM to receive its power and communicate with
the IP Phone
.
