Modular Console Server, Alarm Management
Network 9000 chassis family provides support for a wide range of networking
interface modules that are interchangeable between 3-slot, 6-slot and 15-slot
The Network 9000 provides network administrators with the
flexibility to create application-specific configurations.
To meet the
critical and wide-ranging roles that hubs serve in today's networking
infrastructures, the Network 9000 has been engineered to provide redundancy and
fault tolerance in critical applications. Ease of maintenance features such as
hot swapping of components and automatic module reconfiguration minimize network
downtime. A range of power and density options meets the requirements of all
types and sizes of networks.
midplane architecture of the Network 9000 eliminates the restrictions of
traditional backplane-based hubs. Network administrators can mix and match I/O
modules with processor modules. Processor and I/O modules connect at the
midplane of the chassis and a pair typically occupies one full slot. The
midplane design provides greater flexibility in the selection of connectors and
I/O options, ease of maintenance and module replacements, simplified sparing,
and exceptional flexibility.
The Network 9000 midplane supports three
10-Mbps shared Ethernet segments. Each shared media network is available from
every slot. The midplane also includes a local management bus connecting to all
Reliability and Maintenance
9000 is engineered with a number of features that enhance reliability. Hot
Swapping - Modules, most redundant power supplies, and cooling fans can be
replaced without powering down the unit or interrupting the network. When
modules are swapped, the new module is automatically configured with the
parameters of its predecessor.
Cooling Design - Network 9000
chassis fans provide more than enough cooling capacity so that the unit can
operate even if one or more fans fail. Fans are mounted on slide-in assemblies
for quick replacement.
LEDs - Status LEDs on the front of each
processor module allow a network administrator to quickly determine the status
of the processor module and the interface connections on its companion I/O
module. Distributed management - The SwitchPlane contains a dedicated management
bus to which all modules in the chassis are connected. SNMP and RMON agents
reside on the individual modules. Through the management bus, a single processor
module can provide management access to all other components in the chassis -
even if the network is down.
Software loading - Multiple software
loading options ensure that network administrators can load software to Network
9000 modules from multiple sources, a useful feature for performing software
upgrades and for rebooting after a failure or module swap. Processor modules
also support loading from a network-based load server such as a
workstation-based host. The network administrator can load software images over
local or wide area networks, allowing centralized distribution of updates and
ensuring that all units use the correct software.
Six and Fifteen slot Chassis
The 6 and 15 slot chassis
use interchangeable power supply modules, simplifying sparing. The power supply
system supports AC or DC operation. The redundant version of the AC/DC power
supply system for the 15-slot Network 9000 unit allows for connections to
separate AC/DC power grids, eliminating the power source as a single point of
As critical components of the network architecture, these power
supplies are also manageable. Any Network 9000 processor module allows the 6-
and 15-slot power supplies to be managed via SNMP, a local console or Telnet.
Network administrators need only purchase the minimum number of power
supply modules required to support the modules installed in the chassis.
Additional power supply modules may be added for redundancy or as additional
processor and I/O modules are installed. Adding a second or third power supply
to a Network 9000 6- or 15-slot chassis does not require using another module
slot, as is often the case in a competing product.
The AC and DC
controller modules provide nonvolatile storage of module configurations. When
aprocessor or I/O module is replaced, each retains the network address of its
predecessor. An entirely new chassis can be given the attributes of an existing
chassis by moving the original controller module into the new chassis, greatly
reducing the configuration overhead when replacing or upgrading a chassis.
