Before installing the switch, first verify that the switch is operational by powering it on and observing boot fast. Follow
the procedures in the
For 10/100 ports and 10/100/1000 ports, the cable length from a switch to an attached device cannot exceed 328
feet (100 meters).
For 100BASE-FX fiber-optic ports, the cable length from a switch to an attached device cannot exceed 6562 ft (2
km).
Clearance to front and rear panels meets these conditions:
—
Front-panel LEDs can be easily read.
—
Access to ports is sufficient for unrestricted cabling.
—
Front-panel direct current (DC) power connectors and the alarm connector are within reach of the connection
to the DC power source.
Airflow around the switch must be unrestricted. To prevent the switch from overheating, you must have the following
minimum clearances:
—
Top and bottom: 2.0 in. (50.8 mm)
—
Sides: 2.0 in. (50.8 mm)
—
Front: 2.0 in. (50.8 mm)
Caution:
When the switch is installed in an industrial enclosure, the temperature within the enclosure is greater than
normal room temperature outside the enclosure.
Ensure temperatures inside the enclosure conform to device specifications detailed in
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures.
