Considerations Before Installing

Consider the following items before you install equipment.
The system is designed to operate in a typical environmentally controlled Telco environment. Choose
●
an indoor area that has the following characteristics:
- Temperature- and humidity-controlled, such that the maximum ambient room temperature shall
not exceed the temperature specified in the product data sheet
- Clean and free from airborne materials that can conduct electricity
- Well ventilated and away from sources of heat including direct sunlight
- Away from sources of vibration or physical shock
- Isolated from strong electromagnetic fields produced by electrical devices
- Secured, enclosed, and restricted-access, ensuring that only trained and qualified service
personnel have access to the equipment
Establish at least 3 inches clearance on all sides for effective ventilation. Do not obstruct air intake
●
vents or ventilation grills on the front, side, or rear panel. 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 specifications.
Make sure that your power supplies meet the site power or AC power requirements of the all
●
network equipment.

Installing Power Supply Units

For the ratings and power requirements of each power supply unit, see
for the power supply at http://www.extremenetworks.com.
WARNING!
Be sure that the requirements listed in this section are satisfied when installing all Extreme Networks
power supplies.
When you install power supplies:
Plug power supplies only into properly grounded electrical outlets to help prevent electrical shock
●
and comply with international safety standards.
Use only power cords that are certified for use within the country of use. Do not attempt to modify
●
AC power cords.
Make sure the wall outlet is near the equipment and is easily accessible for quick disconnect.
●
Make sure the voltage and frequency of your power outlet match the system electrical ratings for the
●
equipment. The building and/or power source must provide overload protection.
Use a surge suppressor, line conditioner, or uninterruptible power supply to protect the system from
●
momentary increases or decreases in electrical power.
When inserting a power supply into the bay, do not use excessive force.
●
If multiple power supplies are used with a switch, connect each power supply to a different,
●
independent power source. If a single power source fails, it will affect only that power supply to
