Considerations Before Installing
●
The system is designed to operate in a typical Telco environment that is environmentally controlled.
Choose an indoor area that has the following characteristics:
-
Temperature-controlled and humidity-controlled, to ensure 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 product specifications
for power consumption and component heat dissipation.
●
Make sure that your power supplies meet the site power or AC power requirements of all network
equipment.
Maintenance Safety
●
Use only original accessories or components that are approved for use with this system.
Failure to follow these instructions may damage the equipment or violate required safety and
EMC regulations.
●
The chassis cover should be removed only by Extreme Networks personnel. This system contains no
customer-serviceable components. Repairs to the system must be performed by an Extreme
Networks factory service technician.
●
Disconnect all power cords before working near power supplies, unless a maintenance procedure
instructs you to do otherwise.
●
Replace a power cord immediately if it shows any signs of damage.
●
When you work with optical devices or other modular accessories, wear an ESD-preventive wrist
strap to reduce the risk of electronic damage to the equipment. Connect the other end of the strap to
an appropriate grounding point on the equipment rack. Leave the ESD-preventive wrist strap
permanently attached to the equipment rack so that it is always available when you need to handle
ESD-sensitive components.
●
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief devices.
