Figure 6: Connect Power for FXS Modules
Many modern PCs and servers do not have either spare or any 12V power
connectors. If you have FXS modules on your card and your computer
does not have power cables available, then power must be provided to the
card by an alternate means. Digium provides a solution to this problem
with the optional PWR2400B (available separately). This card is
essentially a PCI bracket assembly that takes power from an external DC
power supply and routes it to two 15” power cables inside the computer.
You must have an available bracket slot to use the PWR2400B (either
PCI, PCI Express or AGP).
A strap on the PWR2400B card allows the two power cables to take
power from the same DC supply. The PWR2400B does not connect to
any bus inside the computer. It may be used wherever there is an available
PCI-size bracket such as a PCI slot, PCI Express slot, or AGP slot.
Note: The PWR2400B is not intended to supply power to any other
device, it is intended only to be used with UL Listed Digium Analog
410 Series cards.
