6.Connected the twisted pair cables to the twisted pair ports.

When connecting a twisted pair cable to a port, observe the following guidelines:

ˆAn RJ-45 connector should fit snugly into the port on the switch. The tab on the connector should lock the connector into place.

ˆCheck that you are using the appropriate type of twisted pair cabling. Refer to “Twisted Pair Cabling and Distances” on page 25 for twisted pair cable specifications.

ˆSince the twisted pair port, when operating in Auto-Negotiation, is Auto MDI/MDI-X, you can use either a straight-through or crossover twisted pair cable to connect any type of network device to a port on the switch. If you disable Auto-Negotiation on the port, the port defaults to MDI-X.

7.Apply power to the switch by plugging the AC/DC power adapter into an AC power outlet, the plug the DC connector to the power receptacle of the switch.

Warning

The power cord is used as a disconnection device. To de-energize equipment, disconnect the power cord.  E3
