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 AC-input power supply 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.
3. This length is specifically between any two stations on a repeated segment.
