Installation Guidelines

Before installing the switch, these guidelines must be met:

•

OL-23803-02

For Catalyst 3560CG-8PC-S, 3560CG-8TC-S, and 2960CG-8TC-L switches, the maximum

recommended ambient temperature is: 104°F (40°C).

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

The operating environment must be within the ranges listed in

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.
