converted into regulated DC power by an EPS200-4850A. The resulting DC power output is
connected to the PEMs through external cables to supply power for all boards and fan modules.
Installing the EPS200-4850A in the same cabinet as the chassis is recommended. If the EPS200-4850A cannot
be installed in the same cabinet as the chassis, it should be placed near the cabinet and careful attention needs
to be paid to the cabling. Each power module provides four circuit breakers. Each circuit breaker is 20 A.
Two -48 V power inputs are joined on the board.

Cause of the Abnormality
A temperature alarm is
generated (if the temperature
exceeds 65°C, the
EPS200-4850A will be powered
off), or the EPS200-4850A is in
the dormant state (the indicator
is on and no alarm is generated).
The EPS200-4850A is powered
off due to over-voltage or over-
temperature, or fans are faulty,
or the EPS200-4850A has no
output due to its internal faults.
