M
midplane The functional equivalent of a backplane. The midplane is secured to the back
of the server. The CPU card, I/O cards and storage devices plug into the
midplane from the front, and the rear transition cards plug into the midplane
from the rear.
N
NEBS An acronym for Network Equipment/Building System. A set of requirements
for equipment installed in telco offices. These requirements cover personnel
safety, protection of property, and operational continuity. “NEBS testing”
involves subjecting equipment to shaking (for earthquakes), fire, and other
environmental insults. There are three levels of NEBS compliance, each a
superset of the preceding. NEBS level 3, the highest level, certifies that a piece
of equipment can be safely deployed in an “extreme environment.” A telco
central office is considered an extreme environment.
The NEBS standards are maintained by Telcordia Technologies, Inc., formerly
Bellcore.
P
PICMG Acronym for the PCI Inductrial Computer Manufacturers Group. (PCI stands
for Peripheral Component Interconnect.) PICMG is the group that promulgates
the CompactPCI standard.
See CompactPCI.
R

come out from the rear of the chassis.
rear transition card Used only on the rear access models of the Netra ct server. The rear transition
cards extend the connectors from the midplane to the rear of the chassis.
