Physical Description

This section provides information for the following hardware interfaces:

•

•

•

RJ-45ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch 
automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex mode (half- or 
full-duplex) of the attached device. All ports support only Unshielded Twisted-Pair (UTP) cable 
terminated with an 8-pin RJ-45 plug.

To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This 
technology allows attaching devices to the RJ-45 ports with either straight-through or crossover 
cables. When inserting a cable into the switch’s RJ-45 port, the switch automatically:

•

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 connecting the port to a PC) or an “uplink” connection (such as when connecting the 
port to a router, switch, or hub).

•

Configures the RJ-45 port to enable communications with the attached device, without 
requiring user intervention. In this way, the Auto Uplink technology compensates for setting 
uplink connections, while eliminating concern about whether to use crossover or straight-
through cables when attaching devices.

Power LED

• Off - Power is disconnected.
• Solid Green - Power is supplied to the switch and is operating 

normally.

MAX POE LED

• Solid Yellow - Indicates that less than 180W of PoE power is 

available.

• Flashing Yellow - Indicates that the PoE MAX LED was active in the 

previous two minutes.

• Off - There is at least 7W of PoE power available for another device.
