About the CSX400
CSX400 and CSX400-DC User’s Guide 7
•The WPIM-T1/DDS provides both a T1 and DDS interface that allows you to easily switch
between the two interfaces by changing the physical cabling and reconfiguring QuickSET for
the desired interface. The WPIM-T1/DDS has the capabilities of both the WPIM-T1 and
WPIM-DDS.

Ethernet LAN Connection

The CSX400 provides 10 Mbps Ethernet/IEEE 802.3 support through two Cabletron Systems
Ethernet Port Interface Modules (EPIMs), which are available in a variety of media types.
Appendix A, EPIM Specifications, details the available EPIMs that can be used to configure the
CSX400 for an Ethernet connection.
FLASH EEPROMs — The CSX400 uses a FLASH Electrically Erasable Programmable
Read-Only Memory (EEPROM) that allows new and updated firmware to be downloaded in
conjunction with Cabletron Systems QuickSET or any device using BootP or TFTP protocols.
LANVIEW LEDs — Cabletron Systems LANVIEW Status Monitoring and Diagnostics System is
a troubleshooting tool that helps in the diagnosing of power failures, collisions, cable faults, and
link problems. The LANVIEW LEDs are located on the CSX400 front panel.
RESET Button — The front panel RESET button reboots the CSX400 and initializes the
processor. The RESET button also is used with the mode switches to clear NVRAM.
