Item Indicator
Color Status Description Cause of the Abnormality
Protection
indicator Yellow If the indicator is off,
the EPS200-4850A is
running properly. If the
indicator is on, an
exception occurs. 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).
Fault indicator Red If the indicator is off,
the EPS200-4850A is
running properly. If the
indicator is on, an
exception occurs. 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.
DC output
voltage - The normal voltage
ranges from –43.2 V
DC to –57 V DC -
Figure 4-8 diagrams the AC power supply system of the CX600-X8. AC power input is
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.
NOTE
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.
NOTE
In Figure 4-11 , each DC power input contains one -48 V power input and one RTN input. Two separated RTN
inputs are joined on the board.
