Redundant power supplies are hot-removable and hot-insertable. When you remove a
power supply from a router that uses only one power supply, the router might shut down
depending on your configuration.

Each AC power supply weighs approximately 2.5 lb (1.13 kg) and consists of a handle, a
power cord retainer clip, an ejection latch, an AC appliance inlet, a fan, and an LED to
monitor the status of the power supply.
Each inlet requires a dedicated AC power feed and a dedicated customer site circuit
breaker. We recommend that you use a dedicated customer site circuit breaker rated for
10 A (100 VAC), 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 SAE 10-32 ground 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 3 lb (1.36 kg) and consists of a handle, an
ejection latch, a status LED, a grounding point, and a terminal block that provides a single
DC input (24, –48, or –60 VDC and return) that requires a dedicated customer site circuit
breaker. We recommend that you provide at least 40 A @ 24 VDC and use a facility circuit
breaker. Figure 16 on page 62
