Maintenance Safety; Cable Routing For Lan Systems - Extreme Networks Summit X150 Series Hardware Installation Manual

Do not work on the system or connect or disconnect cables during periods of lightning activity.
●
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in
●
the absence of a suitably installed ground conductor.

Maintenance Safety

When you perform maintenance procedures on Extreme Networks equipment, follow these
recommendations:
Use only authorized 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.
This system contains no customer serviceable components. Do not attempt to repair a chassis, power
●
supply, module, or other component. In the event of failure, return the defective unit to Extreme
Networks for repair or replacement, unless otherwise instructed by an Extreme Networks
representative.
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
●
product-specific 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 or to an ESD jack on the
chassis if one is provided. Leave the ESD-preventive wrist strap permanently attached to the
equipment rack or chassis so that it is always available when you need to handle components that
are sensitive to ESD.
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief devices.

Cable Routing for LAN Systems

Extreme Networks equipment meets the requirements for LAN system equipment. LAN systems are
designed for intra-building installations; that is, cable runs between devices must be in the same
building as the connected units, except under the conditions listed in the next paragraph.
As allowed in the USA by the National Electrical Code (NEC), this equipment can be connected
between buildings if any one of the following conditions is true:
Cable runs between buildings are less than 140 feet long.
●
Cable runs between buildings are directly buried.
●
Cable runs between buildings are in an underground conduit, where a continuous metallic cable
●
shield or a continuous metallic conduit containing the cable is bonded to each building grounding
electrode system.
CAUTION
Failure to follow these requirements for cable routing conditions may expose the user to electrical shock
and expose the unit to damage that can cause errors.
