Features
The features of the 9A656-04 are described in the sections below:
Processor
The 9A656-04 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides signalling, SNMP management, and serves as the
in-band management LAN Emulation Client (LEC).
Cabletron Systems ASICs
The 9A656-04 contains Þve different Cabletron Systems designed ASICs that
provide a variety of switching services. For more information on these ASICs
refer to Chapter 3.
System Management
The 9A656-04 connects to the two System Management Buses (SMB-1 and
SMB-10) for module management. Management features include the following:
¥ Power and environmental status monitoring
¥ PNNI and ILMI conÞguration
¥ SmartSwitch 9500 chassis IP address assignment
¥ Ability to conÞgure the in-band management LAN Emulation Client
¥ SmartSwitch 9500 chassis and 9A656-04 SNMP community names and trap IP
address assignment
¥ Ability to access Local Management screens of any module installed in the
chassis
Connectivity
The 9A656-04 can be equipped with a variety of front panel interfaces called ATM
Network Interface Modules (ANIMs). ANIMs provide a variety of physical layer
cabling options, including the following:
¥ Unshielded Twisted Pair (UTP)
¥ Multimode Fiber Optic Cable (MMF)
¥ Single Mode Fiber Optic Cable (SMF)
¥ Coaxial Cable
ANIMs are also capable of handling varying amounts of bandwidth including
SONET OC3/SDH, and STS-3/STM-1 (155 Mbps), SONET OC12/SDH
(622 Mbps) and DS3 (45 Mbps). In addition to ANIMs the 9A656-04 is physically
connected to the Cell Transfer Matrix Backplane (CTM), which provides a
dedicated 1.6 Gbps link between all 9A656-04 modules.
