Cabletron Systems CSX200 manual Remote Management Capabilities, Optional Features

Remote Management Capabilities

Polarity Detection and Correction — Each twisted pair port on the CSX200 incorporates a Polarity Detection and Correction feature that allows the CSX200 to pass data regardless of the polarity of the twisted pair segment’s receive link. We do not recommend operating in this condition. When this condition is detected, remove the segment from the network and wire it correctly to reduce the potential for problems if equipment changes are made.

Flash EEPROMs — The CSX200 uses a Flash Electrically Erasable Programmable Read-Only Memory (EEPROM) that allows the downloading of new and updated firmware in conjunction with QuickSET or any device utilizing BootP or TFTP protocols.

LANVIEW LEDs — LANVIEW Status Monitoring and Diagnostics System is a troubleshooting tool that helps in diagnosing power failures, collisions, cable faults, and link problems. The LANVIEW LEDs are conveniently located on the CSX200 front panel.

RESET Button — The front panel RESET button reboots the CSX200 and initializes the processor. The RESET button is also used (with the mode switches) to clear NVRAM.

Remote Management Capabilities

The CSX200 can be managed remotely with any SNMP (Simple Network Management Protocol) compliant network management system.

Optional Features

Rack Mounting Capabilities — The CSX200 can be installed in a 19-inch rack with an accessory package that includes the rackmount brackets, a strain-relief bracket for cable management, and mounting screws. See Chapter 4, Installation, for complete rack mounting instructions.

Hardware Data Compression Module — The same industry standard STAC Electronics Stacker LZS Compression algorithm supported by CSX200 software is made available by an optional hardware data compression module that accelerates data compression for the CSX200 over PPP and Frame Relay. Depending on the packet type and size, hardware data compression provides a minimum of 2:1 data compression, giving (effectively) 3 Mbps throughput on a T-1 WPIM interface. To use the hardware data compression module, compatible equipment (that conforms to the applicable standards), must be in use at both ends of the WAN link. When the hardware data compression module is installed on the board, it automatically assumes the compression task from software. There is no configuration necessary to prioritize hardware over software compression.
