BlackDiamond 8800 Series Switches Hardware Installation Guide

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.
● 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.
Failure to follow these requirements for cable routing conditions may expose the user to electrical shock
and expose the unit to errors or damage.
The intra-building ports of the equipment or sub-assembly are suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intra-building ports of the equipment or sub-assembly must not be metallically
connected to interfaces that connect to the outside plant (OSP) or its wiring. These interfaces are designed for use
as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require
isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.
PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain inside the same building and use a low-voltage power distribution
system per IEEE 802.3af.
