Intra-Networking Hub
A Xyplex Network 9000 Intra-Networking
Hub is a family of products and components that includes chassis, processor modules, I/O
modules, power supplies, and software. Together, these products provide highly reliable
connections to local and remote resources through LAN and WAN links. The Network
9000 Intra-Networking Hub can support many different network configurations, and
network managers can adapt it to suit the needs of different users and computing
environments.
operational parameters
Operational parameters are characteristics that determine
how a Network 9000 processor module operates after initialization. Some operational
parameters are specific to each product, and the network manager can change them with
commands specific to that product. Others are common to all processor modules in the
chassis, such as the link map, and a network manager can change them with chassis
management commands.
parameter file
A parameter file is a file which contains the operational characteristics
for a processor module. These include the link map, the Internet address, security options,
services, and port characteristics for terminal servers. Parameter files can reside on a
parameter server, which is a host on the network, or a flash memory card.
power supply
A power supply is a component of the Network 9000 chassis which supplies
power to the modules in the chassis. The Network 9000 chassis supports two types of power
supplies: model PS/130 managed power supplies and model PS/120 unmanaged power
supplies. Network managers can configure power supplies for redundancy, so that if one
power supply fails the others will compensate for the power loss and the modules will
continue to operate without interruption.
processor module
A processor module is a Network 9000 component that includes the
central processor for the unit and the operational software and parameters.
redundancy
Redundancy is the ability of one component in a system to provide
alternate support if another component in the system fails. Network 9000 power supplies
can provide redundancy to the processor modules and I/O modules in the chassis. For
example, if two power supplies in a six-slot chassis each provide adequate power to support
all the modules in the chassis, one power supply can compensate if the other one fails.
software load image
A software load image is a program that contains the executable
software that makes a processor modules operational. A software load image can reside on
a load server, which is a host on the network, another Xyplex product, or a memory card.
SCM
The Single Chip Microcontroller (SCM) provides the interface between certain
Network 9000 components and the local management bus (LMB). These components
include the AC Input module, processor modules, I/O modules, and managed power
supplies.
SNMP
The Simple Network Management Protocol (SNMP) is a standard Internet protocol
that specifies how network management information is carried through the network.
target slot
A slot that you specify in a chassis management command line, other than
the one where you are logged on.
