To turn on an Extreme Networks switch, do the following.
-
For switches that are connected to AC power,
connect the power cord to the AC power input socket on the switch (or power
supply) and to an AC power outlet.
-
For switches that are connected to DC power, do
the following:
-
Verify that the DC circuit is de-energized.
-
Identify the grounding lug on the rear of
the switch.
The grounding lug is identified
by the international symbol for earth ground:
-
Connect the spade terminal end of the
ground wire to the grounding lug with the M4x0.7 screw provided. Connect
the other end to a reliable earth ground.
Use stranded copper wire, sized
between 14 AWG and 6 AWG.
-
Using a cross-head (Phillips) torque
screwdriver, tighten the retaining screw to 20 in‑lb (2.25
N m).
-
Connect the DC power input cables to the
DC input terminal block on the rear of the switch.
-
Energize the circuit.
-
If applicable, attach the cable from your
redundant power supply (RPS) into the switch‘s redundant power supply
receptacle.
-
When power is connected, verify that the PSU LED
and RPS LED (if applicable) turns green.
When both LEDs have turned green, follow the instructions in Connect Network Interface Cables.
If the PSU and RPS LEDs do not turn green, see the Switch LEDs topic for your
switch model (in the ExtremeSwitching Switches section) for troubleshooting information.
