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. There are no customer
serviceable components in this system. Repairs to the system must be performed by an Extreme
Networks factory service technician.
● In systems that have power-on buttons, the power on button may not turn off all system power. 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
maintenance procedure.
● When handling modules, optic devices, power supplies, or other modular accessories put on the
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.
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 first to
avoid making the rack top-heavy.
● Only use tools and equipment that are in perfect condition. Do not use equipment with visible
damage.
● Routing cables: Route cables in a manner that prevents possible damage to the cables and avoids
causing accidents, such as tripping.
