SWITCH INSTALLATION
10
2.2. Installation Guidelines
The following guidelines are provided to optimize the device performance. Review the
guidelines before installing the device.
Make sure cabling is away from sources of electrical noise. Radios, power lines, and flu-
orescent lighting fixtures can interference with the device performance.
Make sure the cabling is positioned away from equipment that can damage the cables.
Operating environment is within the ranges listed range, see “Specifications” on page 1.
Relative humidity around the switch does not exceed 95 percent (noncondensing).
Altitude at the installation site is not higher than 10,000 feet.
In 10/100 and 10/100/1000 fixed port devices, the cable length from the switch to con-
nected devices can not exceed 100 meters (328 feet).
Make sure airflow around the switch and respective vents is unrestricted. Without
proper airflow the switch can overheat. To prevent performance degredation and dam-
age to the switch, make sure there is clerance at the top and bottom and around the
exhaust vents.
2.3. Environment and Enclosure Guidelines
Review these environmental and enclosure guidelines before installation:
This equipment is intended for use in a Pollution Degree 2 industrial environment, in over-
voltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to
9842 ft (3 km) without derating.
This equipment is considered Group 1, Class A industrial equipment, according to IEC/
CISPR Publication 11. Without appropriate precautions, there may be potential difficulties
If the switch is to be installed in a hazardous location, ensure that the DC power
source is located away from the vicinity of the switch.
The installation of the equipment must comply with all national and local electrical
codes.
Explosion Hazard-The area must be known to be nonhazardous before servicing or
replacing any components.
AIRFLOW AROUND THE SWITCH MUST BE UNRESTRICTED. TO PREVENT THE SWITCH FROM
OVERHEATING, THERE MUST BE 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)
