Connecting to an AC Power Source
This section provides the procedure for connecting your router to an AC power
source. A power factor corrector (PFC) allows the PEM to accept AC power
source voltage from an AC power source operating between 100-120 VAC,
15-Amp service in North America; and a range of 185-264 VAC, 10-Amp service
in an international environment.
Caution
The AC PEM weighs 14.0 pounds (6.35 kg.). Use two hands when handling a
PEM.
Step 1
Attach an ESD-preventive strap to yourself and to either the chassis, or to a bare
metal surface.
Step 2
Using two hands to support and guide the PEM, slide it into the PEM bay. Push
the PEM all the way into the bay until the PEM connector engages the backplane
connector.
Step 3
Tighten the captive screws on the PEM faceplate (
).
