T HE CSX7000OVERVIEWThe CSX7000, the high availability, remote access switch, is a multi-system platform intended forlarge, central sites and Internet Service Providers. It is both modular and flexible, with capabilitiesand performance to match the requirements of high-end network connectivity customers. TheCSX7000 supports a high density of LAN segments, ISDN BRI or PRI, and digital modems, as wellas RS232, V.35, Frame Relay and X.25 interfaces. It also offers an effective means of systemmanagement through its optional Environmental Management System (EMS) module.Modularity: An important feature of the CSX7000 is its ability to support multiple system groups.Each group is a stand-alone CSX “system” based on a Pentium processor module. Use the sixteenISA slots of the CSX7000 as a single system group, or partition it into as many as four systemgroups. A combination of modules (including a processor module) makes up a system group.Flexibility: The CSX7000 supports a flexible setup for system groups; mix and match individualLAN and WAN interface modules within a group to support specific needs.High Availability: Local Area Network (LAN) and Wide Area Network (WAN) interface moduleshave their own dedicated on-board processors and memory, thus lessening the load on the mainprocessor. TDM and MVIP bus connections allow the transfer of data between cards to improvethroughput without using the ISA bus.The fault-tolerant platform provides redundant, hot-swappable power supplies and cooling fans.The platform supports bus segmentation and load sharing. For backup or parallel operations,configure redundant system groups.Environmental Management: The platform contains intelligent environmental sensors to monitorpower, temperature and other environmental functions.GROUP PWRON OFFBC GROUPMULTIPORT BOARDMP SERIAL PORTBC RESETPWR SUPPLY 1PWR SUPPLY 2FANSDATA HIGHWAYSUBSYSTEM FAULTENVIROMENTAL ALLERTAUDIBLE CLEARTRANSMITRECIEVECARRIERDTRDSRRINGRTSCTSLAN ATTATCHEDDISK ACTIVITYENABLEDDISABLEDVIDEO SELECTUNLOCKLOCKMP BCSUBSYSTEM DATACONSOLE
