Preparing a Power Cable for the High-Power (58A) PIU
A 2.5m DC power cable is supplied with each chassis. Additional DC cables can 
be ordered from Alvarion. If necessary, use the following instruction to prepare a 
DC cable.
1
For a cable length up to 2.5m use a cable with 4 x 10AWG (or thicker) wires for 
the power plus and an additional 10AWG (or tghicker) ground wire. For a 
longer cable (up to 10m), use a cable with 4 x 8AWG (or thicker) wires for the 
power plus and an additional 10AWG (or tghicker) ground wire.

The matching power connector to be used is D-SUB 5W5S Female with power 
pins 40A.

Power Supply Unit (PSU)
The single Euro PSU module is a 48 VDC power supply unit. Each Base Station 
chassis can contain up to four PSU modules providing N+1 redundancy 
configurations. 
The following table displays the number of PSU modules (excluding redundant 
units) required for various Base Station configurations:
To prepare the power cable:
CAUTION
It is strongly recommended to always use the power cables available from Alvarion. 
Due to the high current that should be supported by the cable, good workmanship in preparing it is 
essential.
