Preparing And Attaching The Dc Power Supply Cable - Extreme Networks Alpine 3802 Hardware Installation Manual

Installing and Connecting Summit Power Supplies
5 Place both hands on each side of the power supply to slowly and evenly slide the power supply into
the bay.
6 Secure the power supply by tightening the screw on either side of the front panel by using a #2
Phillips screwdriver.
7 Leave the ESD strap permanently connected to the chassis so that it is always available when you
need to handle ESD-sensitive components.
To install an additional power supply, repeat steps 1 through 7.

Preparing and Attaching the DC Power Supply Cable

After you install the power supply in the chassis, you must attach the keyed connector to provide
power to the switch.
NOTE
Do not connect the DC power source cable to the DC power supply until installation is complete.
A three-wire DC wiring harness is included with the Summit48si switch and DC power supply. You
must connect the harness to the DC source voltage at your facility before you connect the keyed
connector to the DC power supply. You should provide proper connection and strain relief on this cable
in accordance with all local and national electrical codes.
WARNING!
Wiring the DC input power harness to your facility 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 Summit48si system without
further electrician assistance.
