Extreme x250e-24t Installation Instruction

Summit Family Switches Hardware Installation Guide

To install an individual EPS-150DC into an EPS-T2:

Attach an ESD-preventive wrist strap to your wrist and connect the metal end to the ground 
receptacle on the top right corner of the switch front panel.

Remove the EPS-150DC from the packing material.

Insert the EPS-150DC into the front of the EPS-T2.

Tighten the provided thumbscrews to secure the power supply to the tray.

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 EPS-150DC unit without further electrician 
assistance.

To connect the DC wiring harness to the EPS-150DC unit:

Verify that the DC power is turned off at the source.

Plug the DC cable connector into the DC power supply socket on the rear of the EPS-150DC unit.

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 

 for the DC wiring harness connector 

 for the DC power socket location on the rear of the EPS-150DC unit. 

Tighten the retainer nut on the connector until it is finger tight.

If you are connecting the EPS-150DC unit to a Summit X450a-48tDC switch, you must ground the 
switch before connecting power. For instructions on grounding the switch, see
