Remote Management CapabilitiesCSX200 Installation Guide2-3Polarity Detection and Correction — Each twisted pair port on the CSX200 incorporates aPolarity Detection and Correction feature that allows the CSX200 to pass data regardless of thepolarity of the twisted pair segment’s receive link. We do not recommend operating in thiscondition. When this condition is detected, remove the segment from the network and wire itcorrectly to reduce the potential for problems if equipment changes are made.Flash EEPROMs — The CSX200 uses a Flash Electrically Erasable Programmable Read-OnlyMemory (EEPROM) that allows the downloading of new and updated firmware in conjunctionwith QuickSET or any device utilizing BootP or TFTP protocols.LANVIEW LEDs — LANVIEW Status Monitoring and Diagnostics System is a troubleshootingtool that helps in diagnosing power failures, collisions, cable faults, and link problems. TheLANVIEW LEDs are conveniently located on the CSX200 front panel.RESET Button — The front panel RESET button reboots the CSX200 and initializes theprocessor. The RESET button is also used (with the mode switches) to clear NVRAM.Remote Management CapabilitiesThe CSX200 can be managed remotely with any SNMP (Simple Network Management Protocol)compliant network management system.Optional FeaturesRack Mounting Capabilities — The CSX200 can be installed in a 19-inch rack with anaccessory package that includes the rackmount brackets, a strain-relief bracket for cablemanagement, and mounting screws. See Chapter 4, Installation, for complete rack mountinginstructions.Hardware Data Compression Module — The same industry standard STAC ElectronicsStacker LZS Compression algorithm supported by CSX200 software is made available by anoptional hardware data compression module that accelerates data compression for the CSX200over PPP and Frame Relay. Depending on the packet type and size, hardware data compressionprovides a minimum of 2:1 data compression, giving (effectively) 3 Mbps throughput on a T-1WPIM interface. To use the hardware data compression module, compatible equipment (thatconforms to the applicable standards), must be in use at both ends of the WAN link. When thehardware data compression module is installed on the board, it automatically assumes thecompression task from software. There is no configuration necessary to prioritize hardware oversoftware compression.
