Using DC Power
The DC power subsystem supports up to two redundant DC power supply units
(PSUs). To remove the PSU, simply press down on the green locking tab while
pulling outward on the PSU handle. To insert the PSU, slide the entire unit (green
locking tab toward the top) fully into the SCG chassis until it locks in place.
If using DC power, connect -48V DC input power to the PSU. The DC input polarity
is marked on the DC PSU case. In
, “-” is on the left and “+” is on the right.
NOTE:
Use #14-#10 AWG to the DC input connector.
CAUTION!
To avoid the potential for electrical shock and fire hazard, ensure that
the DC wiring to the DC input connectors has adequate circuit protection in
accordance with local electrical codes
NOTE:
Information on how to replace the PSU is provided in the
