Chapter 2 Switch Installation (24- and 48-Port Switches) Installing and Removing SFP Modules Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures. Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through cable to an RJ-45 connector on the front panel. (See Figure 2-13.) When connecting to switches or repeaters, use a crossover cable. (See the "Cable and Adapter Specifications" section on page B-4 for cable-pinout descriptions.) When you connect to 1000BASE-T-compatible devices, be sure to use a twisted four-pair, Category 5 or higher cable. The auto-MDIX feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.

Installing and Removing SFP Modules SFP modules are installed in SFP module slots on the front of the Catalyst 2960 switches. These field-replaceable modules provide the uplink optical interfaces, laser send (TX) and laser receive (RX). You can use any combination of SFP modules. Refer to the Catalyst 2960 switch release notes for the list of SFP modules that the Catalyst 2960 switch supports. Each SFP module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications.

Switch Installation (24- and 48-Port Switches)
Installing and Removing SFP Modules
Caution
To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling
procedures.
Step 1
When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through
cable to an RJ-45 connector on the front panel. (See
Figure 2-13
.) When connecting to switches or
repeaters, use a crossover cable. (See the
“Cable and Adapter Specifications” section on page B-4
for
cable-pinout descriptions.)
When you connect to 1000BASE-T-compatible devices, be sure to use a twisted four-pair, Category 5
or higher cable.
The auto-MDIX feature is enabled by default. For configuration information for this feature, see the
switch software configuration guide or the switch command reference.

Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
when both the switch and the connected device have established link.
The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for
loops. This can take up to 30 seconds, and then the port LED turns green. If the port LED does not turn
on, the device at the other end might not be turned on, or there might be a cable problem or a problem
with the adapter installed in the attached device. See
Chapter 4, “Troubleshooting,”
for solutions to
cabling problems.
Step 3
Reconfigure and reboot the connected device if necessary.
Step 4
Repeat Steps 1 through 3 to connect each device.
Installing and Removing SFP Modules
SFP modules are installed in SFP module slots on the front of the Catalyst 2960 switches. These
field-replaceable modules provide the uplink optical interfaces, laser send (TX) and laser receive (RX).
You can use any combination of SFP modules. Refer to the Catalyst 2960 switch release notes for the
list of SFP modules that the Catalyst 2960 switch supports. Each SFP module must be of the same type
as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length
for reliable communications. See the
