Preparing the Cables
Three right-angle lugs (Burndy part number YA6CL1-90, #6 AWG wire lug) are provided with the PSU.
You need a crimping tool to attach the lugs to the power and ground cables.
To prepare the cables:
1 On each wire, strip 0.5 inch of insulation from one end.
2 Slide a 1-inch piece of heat-shrink tubing over the end of the wire.
3 Insert a stripped wire end all the way into the barrel of a lug (Figure 31) and crimp the lug securely
to the wire.
NOTE
Make sure that no copper is visible between the lug and the cable insulation.

4 Slide the heat-shrink tubing over the crimped barrel of the lug and use a heat gun to shrink the
tubing around the lug and wire.
5 Repeat steps 2 through 4 for the other two lengths of wire.
Installing the Power Supply
To install an Extreme Networks 1900 W DC PSU:
1 Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to the ground
receptacle above the switch fabric modules.
2 At each side, completely loosen the captive retaining screws and remove the power supply retainer
from the chassis (see Figure 32).
