There is one Micro-B USB console port located on the front panel. If the Micro-B USB

console port is connected, it is selected over the RJ45 serial 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 console

port; however, no user input is accepted from the RJ45 serial console port.

Note

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 Type A USB 2.0 port labeled USB on the front panel that can host

removable devices like ash drives.

Power Supplies

Most 5320 Series switches have one xed AC power supply unit. The 5320-16P-4XE-

DC switch has one xed DC power supply unit. Models 5320-24T-4X-XT and

5320-24T-24S-4XE-XT provide an option to add an external 150W redundant AC

power supply. For more information regarding the redundant power supply, see the

Redundant Power Supply Quick Reference

Cooling

Switch cooling is provided by xed fan modules that use airow 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.

The external redundant power supply for models 5320-24T-4X-XT and

5320-24T-24S-4XE-XT has its own fan for cooling.

Stacking Ports

Each switch comes equipped with two stacking ports, also referred to as Universal

Ethernet ports. The stacking ports are labeled U1 and U2 and are located on the front

of the switch. When running Switch Engine, these ports can be used in either stacking

mode or Ethernet mode. When in stacking mode, up to eight systems can be stacked

using qualied direct attach cables or optical transceivers. The U1 and U2 ports operate

as stacking ports by default. Use the disable stacking-support command to set the

U1 and U2 ports in Ethernet mode. Fabric Engine does not support stacking, but the U1

and U2 ports can be used as Ethernet ports by Fabric Engine when Fabric Engine is in
