[ANSS-netops] Replacement for motorola 300/320 FRAD

[Kyle Persefield]

Rayo,

We are using Calex DC-DC Converters.  On our Cisco 1721 Routers we 
are using model 24T5.12K-CM converters.  This is a 18-36 VDC input 
brick with a triple output of 5 VDC @ 5000mA and +- 12 VDC @ 1250 
mA.  I believe the 12 VDC input model is 12T5.12K-CM.

Be advised that the Cisco 6 pin power connector is proprietary (you 
can't order one).  You will have to cut the pigtail off the wall wart 
and reuse it.

See attached drawing.
