Introduction
The 9G421-02/9G429-02 (Figure 1-1) is a Gigabit Ethernet interface module,
occupying a single slot in the SmartSwitch 9000 chassis. Gigabit Ethernet
networks are connected to the 9G421-02/9G429-02 through front panel ports.
These ports interface with the switch through Gigabit Network Interface Blocks
(GNIB) and are based upon an ASIC architecture.
The module connects to the Internal Network Bus (INB) B, providing a high
speed backplane for communication among other modules in the SmartSwitch
9000 chassis. The 9G421-02/9G429-02 uses a SmartSwitch ASIC design and an
advanced Intel i960
¨
microprocessor providing a platform for all management
functions within a scalable RISC-Based Architecture.
Network management information is available through a variety of methods. All
information based on Simple Network Management Protocol (SNMP) is
accessible either via an in-band (Front Panel port), Side Band (SMB-10), or via the
Environmental ModuleÕs (EM) COM ports. Serial Line Internet Protocol (SLIP) or
Point-to-Point Protocol (PPP) is supported by the EM COM ports. For more
information on the SMB-10, SLIP or PPP refer to the SmartSwitch 9000 Local
Management UserÕs Guide.
The 9G421-02/9G429-02 features front panel LANVIEW
¨
Diagnostic LEDs to
offer at-a-glance status information about each front panel port as well as the
operation of the overall module.
The 9G421-02 uses a shortwave 850 nanometer laser. The 9G429-02 uses a
longwave 1300 nanometer laser. Follow applicable safety precautions to prevent
injury.
