Connecting the Auxiliary DC Power Output
The PMU can provide an auxiliary DC output when it is fitted with the 
auxiliary power supply board. This board is available with an output of 
13.65 VDC, 27.3 VDC, or 54.6 VDC (depending on the model), and is 
current limited to 3 A, 1.5 A or 750 mA respectively. This power supply is 
permanently on as soon as the 
base station
 has finished powering up, and is 
available on the auxiliary output connector on the rear panel.
You can connect multiple auxiliary power supply boards in parallel for 
redundancy purposes, or to provide an output greater than 40 W. Although 
no active current sharing is used, auxiliary boards connected in parallel will 
current-share before reaching their power limit. The failure (or switching 
off) of one auxiliary board will not load any other paralleled auxiliary boards 
in the circuit.
Auxiliary DC Power 
Output Cabling
Network elements are supplied with a connector, as shown in 
You can use this to connect the PMU’s auxiliary DC power output to 
another device.

available.
