[Asterisk-Users] Digium Cards in Boxes without Power Connectors

[Joe Dennick]

We've run into the same issue with a Compaq (HP) DL-360.  It’s a great
server with a Xeon 2.8 GHz processor.  In fact its overkill for a single
T-1 and about 20 Cisco phones, but there's no way to plug in the FXO
card.  We wanted to run a FAX machine off of that card.  Because these
servers are only 1 U in height (about 1.75 inches), everything is very
tightly integrated.  Stealing power just isn't an option unless you get
busy with a soldering gun and void your warranty.

So you either can't use that machine or you deal with trying to pull the
power through the PCI bus. Any "Fan" card that you put in is going to
just pull the power out of the same PCI bus that the TDM card does.
