Glossary

LAN

LAN is an acronym for Local Area Network.

LANbus I card

A LANbus I card is part of the Xyplex MAXserver family of products,

including terminal servers, bridges, and routers. The Network 9000 adapter card allows
you to use LANbus cards in a Network 9000 chassis.

LIC

A LAN Interface Card (LIC) is a component of the Network 9000 chassis which

provides a connection to an external LAN for Ethernet Link 1 on terminal servers and
WAN bridge/routers.

link

A link is a connection to either a midplane Ethernet segment or an external

network. Different Network 9000 products have different numbers and types of links. For
example, a terminal server has one Ethernet link; a WAN bridge/router has one Ethernet
link and four WAN links.

link map

A link map specifies the connections for all the links on a Network 9000

managed concentrator, terminal server, LAN bridge/router,or WAN bridge/router.
Network managers can change the link map with chassis management commands or
SNMP. Network Managers can change the link map on

link selection

The link selection is a specific connection to either a midplane Ethernet

segment or an external network that the processor module uses to obtain the software load
image and parameter file from the network, or to send information to a dump file.

load image

see software load image

local management bus (LMB)

The local management bus (LMB) is a transport

system that is part of the chassis midplane. The LMB transports management
information among chassis slots, and allows you to monitor the modules in different
chassis slots, and the power supplies. The LMB operates automatically, and users do not
need to enable or manage it.

local slot

The local slot is the slot in the chassis holding the processor module where you

are logged on.

memory card

A memory card is a type of media which contains a software load image

and, optionally, operational parameters for a Network 9000 processor module. Two types of
memory cards exist: "Flash" cards, which are readable and writeable, and can be
upgraded to newer versions of software, and "ROM" or "OTP" cards, which are read-only,
and cannot be upgraded to newer versions of software. Flash cards may include
operational parameters, and ROM cards do not include operational parameters.

midplane

The midplane is a hardware component in the middle of the Network 9000

chassis. It connects the processor module and the I/O module of a Network 9000 product.
Independent I/O modules also plug into the midplane. The midplane supports three
internal Ethernet segments, four Token Ring Segments, and two FDDI segments.

midplane Ethernet segment

A midplane Ethernet segment is one of the three

Ethernet LANs that the Network 9000 supports for managed concentrators, terminal
servers, LAN bridge/routers, or WAN bridge/routers.
