Connecting The Internal Dc Power Supply To The Dc Source Voltage; Grounding A Summit Dc-Powered Switch - Extreme Networks Summit X150 Series Hardware Installation Manual

Chapter 6: Installing Summit Family Switches

Connecting the Internal DC Power Supply to the DC Source Voltage

Before you connect the switch to a power source, complete the physical installation of the switch in the
equipment rack, as described in
X480, X650, and X670 Series)" on page
If you are installing a Summit DC-powered switch, you must ground the chassis before connecting the
switch to the DC source voltage. (See the next section,

Grounding a Summit DC-Powered Switch

Before you connect the power input cable to a Summit DC-powered switch, you must ground the
chassis, following the instructions in this section.
Gather the following materials to ground the Summit DC-powered switch:
Stranded copper wire cable, minimum size 14 AWG, maximum size 6 AWG
●
The wire should be long enough to reach from the installed switch to the facility ground point
Torque screwdriver with 1/4-inch flat blade
●
Additional grounding hardware appropriate to the earth ground connection at your site
●
WARNING!
Be sure to connect the chassis ground wire before you connect any power cables.
To ground the switch:
1 At one end of the wire, strip the insulation to expose 1/2 inch (12 mm) of bare wire.
2 Identify the grounding lug on the back of the switch. The grounding lug is next to the edge of the
back panel, identified by the international symbol for earth ground. Depending on the switch model,
the grounding lug may be on either side (see
