Network 9000 Glossary
This glossary defines some commonly used terms in Network 9000 documentation,
including this manual. Terms that appear in italics are defined elsewhere in the
glossary.
ac input module
The AC input module is a Network 9000 I/O module that provides
power to the control storage of the chassis.
adapter card
An adapter card is a Network 9000 I/O module that allows you to use
LANbus I cards in a Network 9000 chassis.
chassis
A Network 9000 chassis is the physical enclosure that contains the midplane, the
slots for the processor modules and the I/O modules, and compartments for power supplies
and the AC input module. Two types of Network 9000 chassis are available: a six-slot
chassis with compartments for two power supplies and a fifteen-slot chassis with
compartments for five power supplies.
chassis management commands
Chassis management commands are a set of
commands that reference chassis slots and power supplies, and can change the operational
link map, the status and parameters of initialization records, and reset processor modules
and power supplies. Network managers can use these commands to manage modules
locally or remotely, without using the initialization configuration menu.
configuration menu
see initialization configuration menu.
control storage
The chassis provides control storage that contains slot-specific
information, as well as the three initialization records for the processor modules in each
chassis slot.
dump file
A dump file is a file that resides on a dump server, which is a host on the
network. If a processor module fails for some reason, it sends the contents of its memory to
the dump server, which create the dump file. Xyplex field personnel can then analyze the
contents of the dump file to diagnose the failure.
Ethernet
An Ethernet, as defined by the IEEE 802.3 standard, is a type of local area
network (LAN). The Network 9000 midplane supports three separate Ethernet segments.
firmware
Firmware is
a
type of
program that resides in read-only memory (ROM).
The firmware in a Network 9000 processor module contains an initialization program
which begins executing automatically when you power on a processor module.
