Considerations Before Installing
Consider the following items before you install equipment.
• For equipment designed to operate in a typical Telco environment that is
environmentally controlled, choose a site that has the following characteristics:
â—¦ Temperature-controlled and humidity-controlled, such that the maximum
ambient room temperature shall not exceed what the equipment manufacturer
recommends.
â—¦ Clean and free from airborne materials that can conduct electricity.
â—¦ Well ventilated and away from sources of heat including direct sunlight.
â—¦ Away from sources of vibration or physical shock.
◦ Isolated from strong electromagnetic elds produced by electrical devices.
• For equipment designed to be installed in environments that are not
environmentally controlled, such as outdoor enclosures, see the product data sheet
or for environmental conditions, temperature, and humidity.
• Establish at least 3 inches clearance on all sides for effective ventilation. Do not
obstruct the air intake vent on the front, side, or rear ventilation grills. Locate the
system away from heat sources.
• Make sure that your equipment is placed in an area that accommodates the power
consumption and component heat dissipation specications.
• Make sure that your power supplies meet the site DC power or AC power
requirements of all the network equipment.
• Racks for Extreme Networks equipment must be permanently attached to the oor.
Failure to stabilize the rack can cause the rack to tip over when the equipment is
removed for servicing.
• Do not operate the system unless all modules, faceplates, front covers, and rear
covers are in place. Blank faceplates and cover panels are required for the following
functions:
â—¦ Preventing exposure to hazardous voltages and currents inside the equipment
â—¦ Containing electromagnetic interference (EMI) that might disrupt other
equipment
◦ Directing the ow of cooling air through the equipment
• Ultimate disposal of this product should be handled according to all national laws
and regulations.
General Safety Precautions
Follow these guidelines:
• Do not try to lift objects that you think are too heavy for you.
• When you install equipment in a rack, load heavier devices in the lower half of the
rack rst to avoid making the rack top-heavy.
• Use only tools and equipment that are in perfect condition. Do not use equipment
with visible damage.
• Route cables in a manner that prevents possible damage to the cables and avoids
causing accidents, such as tripping.
