DC Power Supply for ACX5400 Routers

The two power supply modules (PSMs) in ACX5400 routers are hot-removable and hot-insertable
field-replaceable units (FRUs). The PSMs are installed in the router at the factory. The DC power supply
in ACX5448 is 650 W and ACX5448-D and ACX5448-M is 850 W with dual feeds for power resiliency.
You can install replacement PSMs without powering off the router or disrupting the router function.

CAUTION:
a PSM with a different airflow is inserted into the chassis.
