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 <b>12 VDC input</b> model is
12T5.12K-CM.<br><br>
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.<br><br>
See attached drawing. <br><br>

<blockquote type=cite class=cite cite="">Hi Folks,<br><br>
We are looking at replacing some of the older Motorola FRAD's we use
with<br>
something that is easier to configure, deploy and remotely monitor in
the<br>
field. Our current setup consists of Motorola Vanguard 300 and 320
models.<br>
We configure these in both SLIP as well as Ethernet (RJ45) mode.<br><br>
Our main data receiving points at Caltech are all Cisco routers so
we<br>
looked at the Cisco 1720 routers with CSU/DSU cards. The problems
there<br>
are the voltage and current draw. These units require + and - 12V and
5<br>
Volts. And the current draw is pretty high(almost 15-20 Watts of
power).<br>
In places that the station is backed up on a battery, using an inverter
we<br>
would get data for only a few hours after a power failure.<br><br>
I am looking for alternate solutions or suggestions from people that
use<br>
CSU/DSU FRADS with some or most of the following features:<br><br>
1) low power<br>
2) field hardened<br>
3) uses 110V AC or 12V DC power<br>
4) capable of SLIP and Ethernet<br>
5) easy to setup, use standard templates possibly browser-based<br>
configuration<br>
6) remotely monitored via SNMP<br>
7) reasonably priced or available as used<br><br>
Thanks in advance,<br>
cheers,<br>
