This section is specific to the Catalyst 2960 8-port switches. For information applicable to the other Catalyst 2960 switches, see Chapter2, “Switch Installation (24- and 48-Port Switches)”
When you determine where to place the switch, be sure to observe these requirements:
We strongly recommend that you allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.
If the switch is installed in a closed environment or in a multirack assembly, the temperature around it might be greater than normal room temperature.
– You can easily read the front-panel indicators.
– Access to ports is sufficient for unrestricted cabling.
– The AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
When you use shorter lengths of single-mode fiber-optic cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver.
When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module at each end of the link.
This section is specific to the Catalyst 2960 8-port switches. For information applicable to the other Catalyst 2960 switches, see Chapter2, “Switch Installation (24- and 48-Port Switches)”
You need this equipment to install the switch:
You can order an optional cable guard to secure cables to the front of the switch and prevent them from being accidentally removed. To order a cable guard, contact your Cisco representative and use these part numbers:
The cable guard is a different part than the cable guide, which you can use to manage a large number of cables in a rack on switches other than the Catalyst 2960-8TC-L and Catalyst 2960G-8TC-L switches.
The switch has security slots in the left and right side panels. You can install an optional cable lock, such as the type that is used to secure a laptop computer, to secure either or both sides of the switch. Cable locks are available from most computer accessory suppliers.
Installing the Catalyst 2960 8-port switches in a 19-inch rack requires an optional bracket kit that is not included with the switch. You can order a kit containing the 19-inch rack-mounting brackets and hardware from Cisco. The kit part number is RCKMNT-19-CMPCT=.
If you want to connect a terminal to the switch console port, you need to provide an RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) with that adapter from Cisco.
The switch getting started guide on Cisco.com describes the box contents. If any item is missing or damaged, contact your Cisco representative or reseller for support.
You need to supply a number-2 Phillips screwdriver to rack-mount the switch.
Before installing the switch in a rack, or on a desk, a shelf, or a wall, you should power on the switch and verify that it passes POST.
To power on the switch, connect one end of the AC power cord to the AC power connector on the switch, and connect the other end of the power cord to an AC power outlet.
You can power the Catalyst 2960PD-8TT-L switch through a 10/100/1000 uplink port, which can receive power from an upstream PoE switch. You can also connect the switch to an AC power adapter on the rear panel. See the “Power Input Port (Catalyst 2960PD-8TT-L Switch)” section for more information.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When the switch begins POST, the System, Status, Duplex, and Speed LEDs turn green. The System LED blinks green, and the other LEDs remain solid green.
When the POST completes successfully, the System LED remains green. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the System LED turns amber.
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, or on a desk, a shelf, or a wall, as described in the “Installing the Switch” section.

The switch can be installed on top of a desk or shelf with or without mounting screws. If you do not want to use the mounting screws, follow these steps:
Step 1 Locate the adhesive strip with the rubber feet in the accessory kit.
Step 2 Remove the four rubber feet from the adhesive strip, and attach them to the recessed areas on the bottom of the unit. This prevents the switch from sliding on the desk or shelf.
Note We strongly recommend that you attach the rubber feet. Doing so helps prevent airflow restriction and overheating.
Step 3 Place the switch on the desk or shelf.
Note We strongly recommend that you allow at least 3 inches (7.6 cm) of clearance around the ventilation openings to prevent airflow restriction and overheating.
Do not stack switches or place switches side-by-side unless they are separated on all sides by at least 3 inches (7.6 cm) of clearance from each other.
Do not place any items on the top of the switch.
After the switch is mounted on the desk or shelf, do these tasks to complete the installation:
1. Power on the switch. See the “Verifying Switch Operation”.
2. Connect to a 10/100 or 10/100/1000 port, and run Express Setup. See the switch getting started guide for instructions.
3. Connect to the front-panel ports. See the “Connecting to the 10/100 and 10/100/1000 Ports” section, the “Connecting to SFP Modules” section, and the “Connecting to a Dual-Purpose Port” section to complete the installation.
For configuration instructions about using the command-line interface (CLI) setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.”
This section is specific to the Catalyst 2960 8-port switches. For information applicable to the other Catalyst 2960 switches, see Chapter2, “Switch Installation (24- and 48-Port Switches)”
The switch can be secured to a desk or shelf with mounting screws.
Step 1 Locate the screw template. You can use the template to align the mounting screw holes and also as a guide to make sure that you install the screws into the desk or shelf with proper clearance.
Step 2 Position the screw template on top of the desk or shelf so that the two side-by-side slots face the front of the desk or shelf, as shown in Figure 3-1. This ensures that the power cord faces the rear of the desk or shelf after the switch is installed.
Note Wait before you attach the screw template to the desk or shelf.
