BlackDiamond 8800 Series Switches Hardware Installation Guide
157
● 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 power cord immediately if it shows any signs of damage.
General Safety Precautions
Follow these guidelines:
● Do not attempt 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.
Cable Routing for LAN Systems
The BlackDiamond 8800 series switches meet 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.
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 errors or damage.
