2.3.5.1 Preparing a Power Cable for the 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 thicker) 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 thicker) ground wire.
2 The matching power connector to be used is D-SUB 5W5S Female with power
pins 40A.
3 Connect the cable to the power connector as follows:
» Pin 1 (RTN): Red (10/8 AWG min wire)
» Pin 2 (-48V): Black (10/8 AWG min wire)
» Pin 3 ( ): Ground (shield), Green/Yellow (10AWG min wire)
» Pin 4 (-48V): Black (10/8 AWG min wire)
» Pin 5 (RTN): Red (10/8 AWG min wire)
4 Attach suitable terminal rings to the side that connects to the power source.
