Introduction
The 9G426-02 (Figure 1-1) is a two front panel port switching module, occupying
a single slot in the MMAC chassis. The module connects to the Internal Network
Bus B, providing a high speed backplane for communication among other
modules in the MMAC-Plus chassis. This module uses a SmartSwitch ASIC
design and an advanced Intel i960
®
microprocessor. This microprocessor provides
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 Module’s COM ports. Serial Line Internet Protocol (SLIP) or
Point-to-Point Protocol (PPP) are supported by the Environmental Module’s
COM ports. For more information on the SMB-10, SLIP or PPP refer to the
MMAC-Plus Local Management User’s Guide.
The 9G426-02 also features front panel LANVIEW™ Diagnostic LED’s to offer at-
a-glance status information about each front panel port as well as the operation of
the overall module.
Ethernet networks are connected to the 9G426-02 module through GPIMs built
into the front of the module. These ports interface with the FPS switch through
GIGA-BIT Network Interface Blocks (GNIB) and are based upon an ASIC
architecture. The GPIMs are Fiber Channel and are MMF with SC connectors.
The 9G426-02 Module uses GPIMs which utilize a 850 nanometer laser. Follow
applicable safety precautions when using this module to prevent injury.
