The power supply modules are cooled by its own internal cooling system. A fan present in the power
supply module monitors and maintains the temperature inside.
AC Power Supply Description
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 9 on page 34
shows the AC power supply.
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.

DC Power Supply Description
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.
