Connect to the Switch Ports
This section describes how to connect to the fixed switch ports and to the SFP 
module ports.
Connect to the 10/100 and 10/100/1000 Ports
Follow these steps:
The fixed ports on the Catalyst 2960 PoE switches provide PoE support for 
devices that are compliant with IEEE 802.3af. They also provide Cisco 
prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
Each of the Catalyst 2960-24PC-L switch 10/100 ports and ports 1 to 8 on the 
Catalyst 2960-24LT-L deliver 15.4 W of PoE.
By default, a Catalyst 2960 switch PoE port automatically provides power when 
a valid powered device is connected to it. For information about configuring and 
monitoring PoE ports, see the switch software configuration guide. For 
information about troubleshooting PoE problems, see the Catalyst 2960 Switch 
Hardware Installation Guide on Cisco.com.
NoteThe automatic medium-dependent interface crossover (auto-MDIX) feature is 
enabled by default. The switch detects the required cable type for copper Ethernet 
connections and configures the interfaces accordingly. Therefore, you can use 
Step 1When 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 10/100 or 
10/100/1000 port. Use a crossover, twisted 
four-pair, Category 5 cable when you connect 
to other switches, hubs, or repeaters.
Step 2Insert the other cable end into an RJ-45 connector on the other device.

Verify Port Connectivity
After you connect to the switch port and another device, the port LED turns amber 
while the switch establishes a link. This process takes about 30 seconds, and then 
the LED turns green when the switch and the target device have an established 
link. If the LED is off, the target device might not be turned on, there might be a 
cable problem, or there might be a problem with the adapter installed in the target 
device. See the 
“In Case of Difficulty” section on this page for information about 
online assistance.
In Case of Difficulty
If you experience difficulty, help is available here and on Cisco.com. This section 
includes Express Setup troubleshooting, how to reset the switch, how to access 
help online, and where to find more information.
Troubleshooting Express Setup
If Express Setup does not run, or if the Express Setup page does not appear in your 
browser:
 Did you verify that POST successfully ran 
before starting Express Setup?If not, make sure that only the SYST and STAT 
LEDs are green before pressing the Mode button 
to enter the Express Setup mode.
 Did you press the Mode button while the 
switch was still running POST?If yes, wait until POST completes. Power cycle the 
switch. Wait until POST completes. Confirm that 
the SYST and STAT LEDs are green. Press the 
Mode button to enter Express Setup mode.
 Did you try to continue without confirming 
that the switch was in Express Setup mode?Verify that all LEDs above the Mode button are 
green. (The RPS LED is off.) If necessary, press 
the Mode button to enter Express Setup mode.
 Does your PC have a static IP address?If yes, before connecting to the switch, change 
your PC settings to temporarily use DHCP.
