Pluggable Transceiver Modules
Extreme Networks offers several optical transceiver modules for transmitting and receiving data over
optical fiber rather than through electrical wires.
Optical Cables
Direct-attach copper and fiber cables provide connections between populated SFP+, SFP28, QSFP+,
and QSFP28 ports.
Turn on the Switch
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 a 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
page 78.
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.
1. 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.
2. Verify that the DC circuit is de-energized.
3. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an
appropriate ground point on the rack.
4. 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.
5. Insert the cable wires into the terminal connector.
