Connect to the Switch Ports

This section describes how to connect to the fixed switch ports and to the GBIC module ports.

Connect to 10/100 and 10/100/1000 Ports

Follow these steps:

Step 1 When you connect to servers, workstations, IP phones, wireless access points, and routers, insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/1001 or 10/100/1000 port. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.

Step 2 Insert the other cable end into an RJ-45 connector on the other device.

1.The Catalyst 3550-24PWR switch 10/100 inline power ports, also referred to as pre-standard Power over Ethernet (PoE) ports, provide –48 VDC power and protocol support for Cisco IP Phones and Cisco Aironet Access points. See the hardware installation guide on Cisco.com for more information about PoE ports.

Warning	Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
	interconnections are made using uninsulated exposed metal contacts, conductors, or
	terminals. Avoid using such interconnection methods, unless the exposed metal parts
	are located within a restricted access location and users and service people who are
	authorized within the restricted access location are made aware of the hazard. A
	restricted access area can be accessed only through the use of a special tool, lock and
	key or other means of security. Statement 1072
