Statement 1079

Note Applies to the Catalyst 3560CG-8PC-S switch.

Installation Guidelines

Before installing the switch, these guidelines must be met:

•The operating environment must be within the ranges listed in Appendix A, “Technical

Specifications.”

•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent

lighting fixtures. Make sure that the cabling is away from other devices that might damage the

cables.

•Airflow around the switch and through the vents must be unrestricted. We strongly recommend that

you allow at least 3 in. (7.6 cm) of clearance from the left, right, and top sides of the switch to avoid

any flow blockage. If you are installing the switch in a rack, allow at least 1.75 in.

(4 cm) of empty rack space above each switch.

•Catalyst 3560CG-8PC-S, 2960C-8PC-L, 2960C-12PC-L, 3560C-8PC-S, and 3560C-12PC-S

switches: Allow at least 1.75 in. (4 cm) clearance from the ends of the external heat sink fins.

Chapter 2 Switch Installation

Powering the Switch

•Temperature around the unit does not exceed 113°F (45°C).

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.

•Humidity around the switch must not exceed 95 percent.

•Altitude at the installation site must not be greater than 10,000 feet (3,049 meters).

•Do not place any items on the top of the switch.

•Do not wall-mount the switch with its front panel facing up. Following safety regulations,

wall-mount the switch with its front panel facing down or to the side to prevent airflow restriction

and to provide easier access to the cables.

•Clearance to the switch front and rear panels meets these conditions:

–

You can easily read the front-panel LEDs.

–

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.

•For 10/100 and 10/100/1000 fixed ports, cable lengths from the switch to connected devices are not

more than 328 feet (100 meters).

•For cable lengths for small form-factor pluggable (SFP)-module connections, see the “SFP Module

Connectors” section on page B-2 and the module documentation.

Equipment That You Supply

You might need this equipment to install the switch:

•Number-2 Phillips screwdriver

•Drill with a #27 drill bit (0.144-inch [3.7 mm])

Box Contents

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.

Powering the Switch

Before installing the switch in a rack, on a desk, a shelf, or a wall, you should power on the switch and

verify that it passes POST.

Power the switch:

Catalyst 2960CPD-8PT-L and 2960CPD-8TT-L

•Connect a 10/100/1000 uplink port to a PoE or PoE+ switch, such as a Catalyst 3750-X.

•Plug the auxiliary power adapter cord into the switch AUX power connector and into an AC power

outlet.

Chapter 2 Switch Installation

Verifying Switch Operation

Note You can use both the uplink port and the auxiliary power adapter. However, the auxiliary power

input takes precedence.

Catalyst 3560CPD-8PT-S

•Connect a 10/100/1000 uplink port to a PoE+ switch, such as a Catalyst 3750-X.

•Plug the auxiliary power adapter cord into the switch AUX power connector and into an AC power

outlet.

Note You can use both the uplink port and the auxiliary power adapter. However, the auxiliary power

input takes precedence.

All models (except the Catalyst 2960CPD-8PT-L, 2960CPD-8TT-L, and 3560CPD-8PT-S)

•Plug the AC power cord to the switch AC power connector and into an AC power outlet.

Verifying Switch Operation

As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the

switch functions properly. LEDs blink during the test, which 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 green.

When the POST completes successfully, the System LED turns 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, unplug the power cord from the switch. Mount the switch in a rack on a desk

or shelf, under a desk or shelf, or on a wall, as described in the “Mounting the Switch” section on

page 2-5.

Mounting the Switch

•On a Desk or Shelf (without Mounting Screws)

•Desk, Shelf, or Wall (with Mounting Screws)

•With a Mounting Tray

•In a Rack

•On a DIN Rail

Chapter 2 Switch Installation

Mounting the Switch

On a Desk or Shelf (without Mounting Screws)

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.

Warning

To prevent airflow restriction, allow clearance around the ventilation openings to be at least:

3 in. (7.6 cm)

Statement 1076

After you mount the switch, see the “After Installing the Switch” section on page 2-31 for information

about the switch configuration.

Desk, Shelf, or Wall (with Mounting Screws)

You can use the mounting screws to mount the switch:

•On a desk or a shelf

•Under a desk or a shelf

•On a wall

Desk- or Shelf-Mounting

Step 1 Use the screw 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 2-1. 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.

Step 3 Peel the adhesive strip off the bottom of the screw template, and attach it to the top of the desk or shelf.

Step 4 Use a 0.144-inch (3.7 mm) or a #27 drill bit to drill a 1/2-inch (12.7 mm) hole in the three screw

template slots.

Step 5 Insert three screws in the slots on the screw template, and tighten them until they touch the top of the

screw template.

Step 6 Remove the screw template from the desk or shelf.

Step 7 Place the switch onto the mounting screws, and slide it forward until it locks in place. See Figure 2-2.

Under the Desk- or Shelf-Mounting

Step 1 Use the screw template to align the mounting screw holes and also as a guide to make sure the screws

are installed under the desk or shelf with proper clearance.

Step 2 Position the screw template underneath the desk or shelf so that the two side-by-side slots face the front

of the desk or shelf, as shown in Figure 2-3. This ensures that the power cord faces the rear of the desk

or shelf after the switch is mounted.

Step 3 Peel the adhesive strip off the bottom of the screw template, and attach it to the underside of the desk or

shelf.
