Introduction
The 9E423-36 (Figure 1-1) is a 36-port switching module. Three RJ-21 Telco
connectors support 36 10BASE-T ports with a port connecting to the Internal
Network Bus (INB) backplane interface. 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.
The module can operate in two modes: as a 36-port Ethernet traditional switch
(using 802.1d standards) with a high speed backbone connection or as a Secure
Fast Switch (SFS) with 36 Ethernet connections. Each port of the 9E423-36 can be
configured to operate in the Full Duplex mode. This configuration allows each
port to provide a full 20 Mbps of bandwidth for file servers or high end user
intensive workstations.
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) is supported by the Environmental Module's COM
ports. For more information on the SMB-10, SLIP or PPP, refer to the SmartSwitch
9000 Local Management User's Guide.
The 9E423-36 also 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.
Ethernet networks are connected to the 9E423-36 module through three standard
RJ-21 Telco connectors built in the front of the module. Each connector provides
12 Ethernet 10BASE-T connections for UTP and STP links up to 100 meters long.
