AC Powered IPE

An AC-powered IPE can only be configured as a remote IPE behind the Fiber
IPE interface (FII) or the T1 IPE interface (TII) product. In the AC-powered
systems, power components external to the IPE are not required. AC systems
perform a single conversion from the AC input voltage to the DC voltages
required by circuit cards in each module. Optional reserve power requires an
uninterruptible power supply (UPS) and batteries.

Foreign voltage protection

Use extreme care when punching down or removing a pair in feeder closets
that also house Centrex pairs and digital sets that are attached to the IPE. This
could cause foreign voltage to be shorted to the IPE. In this case, the IPE resets
itself and must be reloaded and returned to service manually. All punch down
tools should be insulated to prevent accidental contact with any other pins, and
pull jumpers off the main distribution frame before troubleshooting in feeder
closets.
