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 ZoneDirector 5000 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 the figure below, “-” is on the left and “+” is on the
right.
Note: Use #14-#10 AWG to the DC input connector.
