Considerations Before Installing; Maintenance Safety - Extreme Networks BlackDiamond 8806 Hardware Installation Manual

Considerations Before Installing

Consider the following items before installing equipment.
The system is designed to operate in a typical Telco environment that is environmentally controlled.
●
Choose a site that has the following characteristics:
Temperature- and humidity-controlled, such that the maximum ambient room temperature shall
●
not exceed 40ºC (104ºF)
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 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 specifications.
Make sure that your power supplies meet the site DC power or AC power requirements of all
●
network equipment.

Maintenance Safety

When you perform maintenance procedures on Extreme Networks equipment, follow these
recommendations:
Use only original accessories or components 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 only be removed 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.
To remove power from the system, you must unplug all power cords from wall outlets. The power
●
cord is the disconnect device to the main power source.
Disconnect all power before removing the back panel of any Extreme Networks switch, unless
●
otherwise instructed by a product specific maintenance procedure.
Disconnect all power cords before working near power supplies, unless otherwise instructed by a
●
product-specific maintenance procedure.
When you handle modules, optic devices, power supplies, or other modular accessories put on an
●
ESD-preventive wrist strap to reduce the risk of electronic damage to the equipment. Connect the
other end of the strap to the ESD connector on the front of the chassis. Leave the ESD-preventive
wrist strap permanently attached to the chassis 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.
●
Replace a power cord immediately if it shows any signs of damage.
