ExtremeSwitching 5320 Series Overview
There is one Micro-B USB console port on the front panel. If the Micro-B USB console port is connected,
it is selected over the RJ45 console port. The Micro-B USB console port disconnects when the switch is
rebooted. You can re-connect the port if needed. When the Micro-B USB console is active, any
messages from the switch to the client terminal are echoed to both the USB console and the RJ45 serial
port; however, no user input is accepted from the RJ45 serial port.
Tip
Using a Micro-USB Type B to USB Type A cable, connect the Micro-USB Type B end to the
switch, and the USB Type A end to a laptop or PC and complete the driver installation steps.
There is also a USB 2.0 Type A port. It can be used for a Bluetooth dongle or for attaching a removable
memory module.

Cooling

Switch cooling is provided by fixed fan modules that use airflow from side-to-side (left to right). Switch
fans are also responsible for cooling the power supplies; the power supplies do not have integrated
cooling fans that operate independently of the switch fan.
Fan-off operation at temperatures up to 35⁰C is supported on 5320 16-port AC- and DC-powered
models. These models are perfect for classrooms, hospitality suites, retail sites, or other noise sensitive
environments outside of a wiring closet.

Power Supplies

Most 5320 Series switches have one fixed AC power supply unit. The 5320-16P-4XE-DC switch has one
fixed DC power supply unit.

Stacking

Each 5320 Series switch comes equipped with two 10Gb stacking ports. When running Switch Engine,
up to eight switches can be stacked using qualified SFP+ direct attach cables and optical transceivers
located on the front panel of the switch. Standard 10 Gb Ethernet Optics and passive and active cables
can be used in the SFP+ ports for stacking 5320s together using SummitStack-V40 stacking (10G link
running at HG).
Note
The two stacking/SFP+ ports are "Universal Ethernet" ports, labeled "U1" and "U2." These
ports can operate either as stacking ports with Switch Engine or as Ethernet ports with
Switch Engine and with Fabric Engine in non-fabric mode. When used as Ethernet ports, the
U1 and U2 ports can support data rates of 10Gb using SFP+ optics and the appropriate license.
No license is required to use the U1 and U2 ports as 10Gb stacking ports, or as 1Gb ports with
stacking disabled.
Use the disable stacking-support command to set the U1 and U2 ports in Ethernet
mode.
Stacking cables for 5320 Series switches are ordered separately.
