CAUTION: Each three-input 240-A power supply weighs approximately 25 lb (11.3 kg).
Be prepared to support the full weight of the power supply as you remove it from
the routing platform.
CAUTION: Do not leave a power supply slot empty for more than a short time while
the router is operational. For proper airflow, the power supply must remain in the
chassis or a blank panel must be used in an empty slot.
