Cable Routing For Lan Systems - Extreme Networks 8720 Hardware Installation Manual

Safety and Regulatory Information
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.
