QDH Internal Module DC Power Harness

The QDH power harness delivers DC power to modules from a QPS1 or QPS3 power supply, or from a Q103 DC power module that is getting its power from another cabinet.

Some modules consume more than one space, and some modules don't require power like the Q124 Multiple. The QDH20 harness has 10) 24-inch cables, and 10) 36-inch cables which is normally enough for a 22-space cabinet. The QDH40 harness has 20) 24-inch cables, and 20) 36-inch cables which is normally enough for a 44-space cabinet.

Connectors are female 6 pin which mate to the male connector on the circuit board of each module. Connectors are keyed to prevent incorrect connections. One special branch of the cable has a male 4 pin connector which attaches to the power supply.
