Extreme Networks Consolidated ExtremeXOS Hardware Installation Guide
323
Installing an EPS-150DC unit includes the following tasks:
● Connecting the DC Wiring Harness to the DC Source Voltage on page 323.
This task must be performed by a licensed, qualified electrician.
● Installing an EPS-150DC Unit into an EPS-T2 on page 324
● Connecting the DC Wiring Harness to the DC Power Socket on the EPS-150DC on page 325
● Connecting the EPS-150DC to a Switch on page 325
Perform these four tasks in the order they are described.
Connecting the DC Wiring Harness to the DC Source Voltage
The EPS-150DC must be connected to a DC power source. A three-wire, 6-foot long DC wiring harness
is included with the EPS-150DC. The DC wiring harness must be properly connected to the DC source
voltage at your facility by a qualified electrician before the connector on the wiring harness can be
attached to the DC power supply socket on the rear of the unit. This section provides information about
connector pinouts, and Appendix B, “Technical Specifications” provides DC power specifications to be
used in connecting the wiring harness to the DC source voltage.
Wiring the EPS-150DC DC wiring harness to your facilities DC source voltage must be performed by a qualified,
licensed electrician. After the wiring harness is connected to a permanent DC voltage source by a qualified, licensed
electrician, you can remove, replace and maintain the ESP-150DC without further electrician assistance. However,
always be sure that the DC circuit is de-energized before connecting or disconnecting the DC power connection at
the rear of the EPS-150DC unit.
The DC wiring harness must be properly connected to a DC main circuit breaker or fuse rated no greater than 20 A.
Provide proper connection and strain relief on the DC wiring harness in accordance with all local and national
electrical codes.
