Glossary
IEEE 802.3z
Defines CSMA/CD access method and physical layer specifications for 1000BASE
Gigabit Ethernet.
LAN Segment
Separate LAN or collision domain.
LED
Light emitting diode used for monitoring a device or network condition.
Local Area Network (LAN)
A group of interconnected computer and support devices.
Media Access Control (MAC)
A portion of the networking protocol that governs access to the transmission
medium, facilitating the exchange of data between network nodes.
MIB
An acronym for Management Information Base. It is a set of database objects that
contains information about the device.
Network Diameter
Wire distance between two end stations in the same collision domain.
Redundant Power Unit (RPU)
A backup power supply that automatically takes over in case the primary power
supply should fail.
RJ-45 Connector
A connector for twisted-pair wiring.
Routing Information Protocol (RIP)
The RIP protocol attempts to find the shortest route to another device by minimizing
the distance vector, or hop count, which serves as a rough proxy for transmission
cost. RIP-2 is a compatible upgrade to RIP. It adds useful capabilities for subnet
routing, authentication, and multicast transmissions.
Straight-through Port
An RJ-45 port which does not cross the receive and transmit signals internally (MDI)
so it can be connected with straight-through twisted-pair cable to any device having
a crossover port (MDI-X). Also referred to as a "Daisy-Chain" port.
