Back Panel
The back panel provides a Kensington lock and AC power receptacle. (The switch integrates a fixed, internal
power supply.) The console port is not for customer use.
The following figures show the back panels.

Switch Hardware Interfaces
The following sections describe the hardware interfaces on the switch.
RJ-45 Ports for 10/100/1000M BASE-T Ethernet Connectivity
All RJ-45 copper ports support autosensing. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10 Mbps, 100 Mbps, or 1 Gbps) and duplex mode (half-duplex
or full-duplex) of the attached device. All ports support a Category 5e (Cat 5e) cable (or higher-rated Ethernet
cable) terminated with an 8-pin RJ-45 connector.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink technology.This
technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables.
When you insert a cable into the switch’s RJ-45 port, the switch automatically performs the following actions:
• Senses whether the cable is a straight-through or crossover cable.
• Determines whether the link to the attached device requires a normal connection (such as when you
are connecting the port to a computer) or an uplink connection (such as when you are connecting the
port to a router, switch, or hub).
• Automatically configures the RJ-45 port to enable communications with the attached device.The Auto
Uplink technology compensates for setting uplink connections while eliminating concern about whether
to use crossover or straight-through cables when you attach devices.
All copper ports also support Power over Ethernet (PoE+).
