Summit Family Switches Hardware Installation Guide

Attaching the DC Wiring Harness to the DC Power Socket on the Switch
After the DC wiring harness is connected to a permanent DC voltage source by a qualified, licensed
electrician, you can remove, replace, and maintain the Summit DC-powered switch without further
electrician assistance.
Be sure that the DC circuit is de-energized before you connect the DC wiring harness to the DC
power socket.
Be sure that proper ESD controls are in use before switch maintenance is performed. This includes but is
not limited to wrist straps that are grounded to the switch chassis and earth grounds.
To attach the DC wiring harness to the internal DC power supply:
1 Plug the DC wiring harness connector into the DC power supply socket on the rear of the switch
(see
Figure 140).
The pins must align properly for the cable to completely connect. Do not force the cable into the
socket until the keyway is aligned properly. Refer to
Figure 139 for the DC wiring harness connector.
Figure 140: DC Power Socket on a Summit X450a Series DC-Powered Switch
Figure 140 shows the rear panel of a Summit X450a series DC-powered switch. The rear panel of other
Summit DC-powered switches may vary slightly; however, the DC power socket is of the same type and the
connection process is the same for all DC-powered switches.
2 Tighten the retainer nut on the connector until it is finger-tight.
3 Energize the DC circuit.
