Most 5320 Series switches have one fixed AC power supply unit. The 5320-16P-4XE switch
has one fixed DC power supply unit. Be aware of whether the power supply you are
connecting is AC-powered or DC-powered. The connection instructions are different
depending upon what type of power is used. Follow the instructions in the following
sections to connect the appropriate power supply to the switch and turn it on.
Connect AC Power
An AC power cord is not included with the AC power supply. You can purchase
AC power cords for use in the US and Canada from Extreme Networks or from your local
supplier. The cord must meet the requirements listed in Power Cord Requirements for AC-Powered Switches and AC Power Supplies.
To turn on the switch, connect one end of the power cord to the AC power input socket
on the device and connect the other end to an AC power outlet. The switch does not
have a power button, so connecting the power cable at both ends turns the switch on.
The grounding connection in the power receptacle and in the power cord properly
ground the power supply and extend that grounding to the switch.
Connect DC Power
DC power and grounding cables are not included with the power supply. You can
purchase #16 AWG copper DC power cables and ground wire for use in the US and Canada
from Extreme Networks or from your local supplier.
Use the following instructions to connect the device to a DC power source.
Strip 0.25 inch (6.35 mm) of insulation from one end of each cable wire. Three
cable wires are needed: two power input cables and one ground cable.
Verify that the DC circuit is
de-energized.
Attach an ESD-preventive wrist
strap to your bare wrist and connect the metal end to an appropriate ground
point on the rack.
Insert a screwdriver into all three slots on the top of the terminal connector
and loosen the screws enough to accommodate a stripped power input cable.
Insert the cable wires into the
terminal connector.
Slide the end of the
ground wire into the ground terminal (labeled GND on the left
side of the connector.
Tighten the screw on the
top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
Slide the end of the negative wire
(–48 V) into the negative terminal (labeled –, in the middle
of the terminal connector).
Tighten the screw on the
top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
Slide the end of the positive wire
(–48 V RTN) into the positive terminal (labeled +, on the right
side of the terminal connector).
Tighten the screw on the
top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
Insert the connector into the
slot on the power supply.
Connect the power cables to the
DC source voltage, using hardware appropriate to the installation site and
following local and national electrical codes.
Energize the circuit. When power
is connected, verify that the PWR LED is green.
