6.11 Adding Expansion Modules
External expansion modules, except the WAN3, connect to the IP Office control unit
using a blue 1 meter (3'3'') expansion interconnect cable.
•
Note
Expansion modules are only detected by the IP Office control unit, if the
Expansion modules are powered up and running before the control unit is
started. The control unit power on process includes a delay to ensure that if
all modules in a system are started at the same time, the expansion modules
should complete their power up before the control unit.
Each module is supplied with an expansion connect cable and a power supply unit . An appropriate locale specific power
cord for the power supply unit, and cables for the ports on the front of the module must be ordered separately.
Warnings
•
No cable other than an Expansion Interconnect cable should be used. Use of any alternate cable will lead to
system failure.
