Connect to an Ethernet Port

Caution To prevent ESD damage, follow your normal board and component handling procedures.

Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only standard-compliant cabling can be used to connect Cisco pre-standard IP Phones or wireless access points or

IEEE 802.3af-compliant devices to PoE ports. A cable or device that causes a PoE fault must be removed from the network.

Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af might not support PoE when connected to the switch by a crossover cable.

Follow these steps:

Step 1

Use a straight-through Category 5 cable to connect a switch 10/100 or 10/100/1000 port to a desktop, wireless access point, IP phone, server, printer, or router.

Use a crossover Category 5 cable to connect a switch port to another switch or a repeater.

Use a twisted four-pair, Category 5 cable to connect a switch 1000BASE-T small form-factor pluggable (SFP) module port to another device.

Step 2	Insert the other cable end in the other device.
Step 3	Wait until the port LEDs on the switch and the attached device are solid green. The solid green
	port LEDs means a successful connection between the two devices.
	Troubleshooting:
	If the port LEDs are not solid green or if either port LED turns amber, make sure that:

•You are using an undamaged Category 5 Ethernet cable.

•The other device is turned on.

Step 4	Repeat Step 1 to Step 3 as necessary.
