Description The 9H531-18 and 9H532-18 modules are equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions such as Spanning Tree, RMON, and MIB support, within a scalable RISC-Based architecture. Management of the 9H531-18 and 9H532-18 modules and SmartSwitch chassis and any optional equipment is accomplished using the Local Management application or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the front panel using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software. Local Management provides the ability to manage the 9H531-18 and 9H532-18. The 9H531-18 and 9H532-18 modules have two interfaces to INB A and B backplanes, and 18 front port connections. The INB interfaces are fixed connections to INB-A and B that allow the modules to communicate with other SmartSwitch 9000 modules supporting various LAN technologies including, Token Ring, FDDI, Ethernet, WAN, Fast Ethernet and ATM. The 9H531-18 is configured with sixteen MT-RJ multimode fiber connectors (compliant with the 802.3u IEEE 100Base-FX specifications) and two Gigabit Uplink Ports. The 9H532-18 is configured with sixteen RJ45 UTP connectors and two Gigabit Uplink Ports. The sixteen RJ45 connectors (compliant with IEEE 802.3u) provide sixteen IEEE 10Base-T/100Base-TX Ethernet ports. The two Gigabit, GPIM connectors (compliant with IEEE 802.3z) provide support for multimode, single mode fiber. GPIMs are not included with the module and are purchased separately. GPIMs are Hot Swappable, i.e., the user can plug a GPIM into the front of the module without taking the module out of the chassis. Currently supported GPIMs include: multimode fiber (GPIM-01) and single mode fiber (GPIM-09).
