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. 
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 cords before working near power supplies, unless otherwise instructed by a 
maintenance procedure. 
Replace a power cord immediately if it shows any signs of damage.
When you work with optical 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 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. 
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.
For Summit desktop equipment installations, do not place a monitor or other objects on top of the 
equipment. The chassis cover is not designed to support weight.
Only use 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.
Cable Routing for LAN Systems
The Summit family switches meet the requirements for LAN system equipment. LAN systems are 
designed only for intra-building installations; that is, cable runs between devices must be in the same 
building as the connected units.
