Power and cabling information for NEBS (Network Equipment-Building System)
GR-1089-CORE
The following comments apply to the IBM servers that have been designated as conforming to NEBS
(Network Equipment-Building System) GR-1089-CORE:
The equipment is suitable for installation in the following:
v
Network telecommunications facilities
v
Locations where the NEC (National Electrical Code) applies
The intrabuilding ports of this equipment are suitable for connection to intrabuilding or unexposed
wiring or cabling only. The intrabuilding ports of this equipment
must not
be metallically connected to the
interfaces that connect to the OSP (outside plant) or its wiring. These interfaces are designed for use as
intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation
from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect
these interfaces metallically to OSP wiring.
Note:
All Ethernet cables must be shielded and grounded at both ends.
The ac-powered system does not require the use of an external surge protection device (SPD).
The dc-powered system employs an isolated DC return (DC-I) design. The DC battery return terminal
shall not
be connected to the chassis or frame ground.
