HiPath 3300
2.10.6 Expansion Cabinet Rack ECR
When installing the system, an ECR in the 19’’ cabinet is required if
● emergency battery operation is necessary during a power failure or if the system requires
uninterruptible power.
The necessary batteries are installed in the ECR.
● the internal system power supply unit for HiPath 3500 or HiPath 3300 is not sufficient
enough to provide power to the overall telephone configuration (corded or cordless tele-
phones).
In this case, the EPSU2-R external power supply unit should be installed in the ECR.
There are switches for the line and battery voltage on the front panel as well as a fuse for pro-
tecting the battery circuit.
The jacks for the line and battery voltage are located on the rear of the housing. The line voltage
is only fed through and can be interrupted using a switch.
