2 Preparing the installation site

CAUTION

Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the input power connectors.

CAUTION

Disconnect the power cord from all power sources to completely remove power from the device.

CAUTION

If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the device.

Preparing the installation site

Cabling infrastructure

Ensure that the proper cabling is installed at the site. Refer to “Hardware Specifications” on page 57 for a summary of supported cabling types and their specifications.

Installation location

Before installing the device, plan its location and orientation relative to other devices and equipment. Switches can be mounted in a standard 19-inch equipment rack that meets EIA-310D standards, or on a flat surface. Be sure to follow the guidelines below when choosing a location.

The site should meet the following requirements:

•Maintain temperatures within 0 to 40οC (32 to 104οF) and humidity levels within 5% to 95%, non-condensing.

•Allow a minimum of 3 in. of space between the sides and the back of the device and walls or other obstructions for proper air flow.

•Allow at least 3 in. of space at the front and back of the device for the twisted-pair, fiber-optic, and power cabling.

•Be accessible for installing, cabling and maintaining the devices.

•Allow the status LEDs to be clearly visible.

•Allow for twisted-pair cable to be always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference, such as radios and transmitters.
