Connecting the X250e or X450a DC Wiring Harness to the DC Source Voltage

A three-wire, six-foot long DC wiring harness is included with each Summit X250e or X450a DC-powered switch.

The DC wiring harness must be properly connected to the DC source voltage at your facility by a qualified electrician before you attach the connector on the wiring harness to the DC power supply socket on the switch. Three-wire Cable Harness shows the wiring harness and connector. For information about the wire-to-pin connection, see Wire-to-Pin Connection Specifications and Pinouts for the DB-9 Console Connector.

Warning

The Summit DC-powered switch and rack must be connected to protective earth ground before installing any switch components. See Grounding a Summit X250e or X450a DC-Powered Switch.

A qualified, licensed electrician is required to wire the DC input power harness to your facility's DC source voltage. After the wiring harness is connected, you can remove, replace, and maintain a Summit DC-powered switch without further assistance from an electrician. However, always be sure that the DC circuit is de-energized before connecting or disconnecting the DC power connections at the rear of the switch.
