Installing the Switch
This section describes rack-mounting using 19-inch and 23-inch rack-mounting brackets. For optional bracket
information and alternate mounting procedures, such as installing the switch in a 24-inch rack or on a wall,
and for additional cabling information, see the Hardware Installation Guide on Cisco.com.
Tools and Equipment
Obtain these necessary tools:
•A Number-2 Phillips screwdriver to rack-mount the switch
•Drill with #27 drill bit (0.144-inch [3.7 mm]) for mounting an 8-port and 16-port switch
Installation Guidelines
When determining where to install the switch, verify that these guidelines are met:
•Clearance to the switch's front and rear panel should meet these conditions:
◦Front-panel LEDs can be easily read.
◦Access to ports is sufficient for unrestricted cabling.
◦AC power cord can reach from the AC power outlet to the connector on the switch's rear panel.
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
•Airflow around the switch and through the vents is unrestricted. To avoid any flow blockage, we strongly
recommend these guidelines:
◦Allow at least 3 in. (7.6 cm) of clearance from the left and the right sides, and the front and rear
of the switch.
◦Allow at least 1.75 in. (4 cm) of clearance from the top cover, if you are installing the switch in
upright position.
◦Allow at least 3 in. (7.6 cm) of clearance from the top cover, if you are installing the switch inverted,
under a table.
◦Allow at least 1 RU of empty rack space above the switch, if you are installing the switch in a rack.
•Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature.
•Humidity around the switch does not exceed 95 percent.
•Altitude at the installation site is not greater than 10,000 feet.
•For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328
feet (100 meters).
•Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing
contaminant build-up inside the chassis, which can result in system malfunction. You must install this

Connecting to the Switch Ports
This section describes how to connect to the fixed switch ports and to the Small Form-Factor Pluggable (SFP)
module ports.
Connecting to the 10/100/100 or 10/100/1000 PoE+ Ports
The fixed ports on the Cisco Catalyst 2960-L Power over Ethernet Plus (PoE+) switches provide:
•PoE+ support for IEEE 802.3at-compliant powered devices
•PoE support for IEEE 802.3af-compliant powered devices
These ports also provide Cisco prestandard PoE support for Cisco IP phones and Cisco Aironet Access Points.
See the Cisco Catalyst 2960-L Hardware Installation Guide for information on PoE budgeting. By default,
a switch PoE port automatically provides power when a compliant device is connected, including PoE, and
PoE+.

Getting Started with the Switch
Connecting to the Switch Ports

The 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 either a crossover or a straight-through cable for connections to a
copper 10/100/1000 module port on the switch, regardless of the type of device at the other end of the
connection.
Note
SUMMARY STEPS
1. Insert a straight-through, twisted four-pair, Category 5 cable in a switch's 10/100/1000 port when you
connect to servers, workstations, IP phones, wireless access points, and routers. Use a crossover, twisted
four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.
2. Insert the other cable end into an RJ-45 port on the other device.
DETAILED STEPS
