Chapter 2 Switch Installation

Installation Guidelines

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

1.75in. (4.4 cm). Statement 1076

Installation Guidelines

Before installing the switch, verify that these guidelines are met:

•Cabling must be kept 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.

•Operating environment is within the ranges listed in Technical Specifications, page A-1

•Relative humidity around the switch does not exceed 95 percent (noncondensing).

•Altitude at the installation site is not higher than 10,000 feet.

•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 Cables, page B-4and the module documentation.

•Airflow around the switch and through the vents is unrestricted. To prevent overheating, the switch must meet the minimum clearance of 1.75 inches (4.4 cm) at the top and bottom. For clearances needed for wall mounting, see specifications in Wall-Mounting, page 2-16.

Note If the switch is installed in a closed or multirack assembly, take into consideration that the temperature around the switch might be greater than normal room temperature and that special accommodations in clearance must be made.

Verifying Switch Operation

Before installing the switch in a rack or on a wall, you should power on the switch and verify that the switch passes the power-on self-test (POST).

To wire the switch to the power source, see Power Supply Installation, page 3-1

When the switch begins POST, the System LED blinks green, and the other LEDs stay green. When the switch passes POST, the System LED turns green. The other LEDs turn off and return to their operating status. If the switch fails POST, the System LED is amber.

Note Contact Cisco Systems immediately if your switch fails POST.

After a successful POST, disconnect the power from the switch. For more information, see Power Supply Installation, page 3-1See the Installing the Switch, page 2-4to install the switch into a rack or onto a wall.
