AC Power Supply Description

DC Power Supply Description

22
Each AC power supply weighs approximately 2.2 lb (1 kg) and consists of a handle, an
ejector lever, an AC appliance inlet, a fan, and status LEDs to monitor the status of the
power supply. Figure 10 on page 22
Each inlet requires a dedicated AC power feed and a dedicated customer-site circuit
breaker. We recommend that you use a minimum 20 A (110 VAC) or 16 A (220 VAC)
customer-site circuit breaker, or as required by local code.
WARNING: The router is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
(sized for 10–32 screws) provided on the chassis in addition to the grounding
pin of the power supply cord. This separate protective earthing terminal must
be permanently connected to earth.

Each DC power supply weighs approximately 2.2 lb (1 kg) and consists of a handle, an
ejection lever, status LEDs, and a terminal block that provides a single DC input (–48
VDC and return) that requires a dedicated customer site circuit breaker. We recommend
that you use a dedicated customer-site circuit breaker rated for 25 A (–48 VDC) minimum,
or as required by local code.
