Connect DC Power to an ACX5400 Router
The power supply module (PSM) in an ACX5400 router is a hot-removable and hot-insertable
field-replaceable unit (FRU). You can remove and replace it without powering off the router or disrupting
routing functions.
WARNING: DC-powered ACX5400 routers are intended for installation only in a
restricted-access location.
NOTE: The battery returns of the DC power supply must be connected as an isolated DC return
(DC-I).
Before you begin connecting DC power to the router:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage
(see “Prevention of Electrostatic Discharge Damage” on page 191).
•
Ensure that you have connected the router chassis to earth ground.
