PEswitch 900TX Installation

This document, the "PEswitch 900TX Installation" manual (Part Number: EK-DESBF-IN. A01, October 1994), describes how to install, configure, and verify the operation of the PEswitch 900TX module.

The PEswitch 900TX is a network module designed to interconnect six 10 Mb/s Ethernet LANs with a high-speed 100 Mb/s Fiber Distributed Data Interface (FDDI) backbone. It operates as a self-learning IEEE 802.1d MAC bridge, offering transparent, protocol-independent data translation (e.g., DECnet, LAT, TCP/IP, Novell IPX) and flexible filtering capabilities. It also supports SNMP for network management.

The manual covers:

• Installation: Instructions for seating the module into a DEChub 900 MultiSwitch or a DEChub ONE docking station using its hot-swap feature, including verifying LED states and connecting UTP/STP cables.

• Configuration: Detailed steps for initial setup via a dedicated setup port (connected to a terminal or PC). This includes navigating menu options for:

  • Resetting to factory defaults or current settings.
  • Viewing current settings.
  • Setting SNMP read/write community and trap addresses.
  • Setting in-band IP address and default gateway.
  • Performing firmware upgrades (Downline Upgrade - DLU) via TFTP, with a critical warning about potential firmware corruption if power is interrupted during Stage 3 of the DLU process.
  • Configuring out-of-band management (OBM) IP address and port speed (for standalone operation).
  • Module-specific options, such as reconfiguring Ethernet Port 4 to an AUI connector in standalone mode.

• Troubleshooting: Guidance on interpreting LED indicators (Power, Module OK, Port State, Network Activity, FDDI PHY) to diagnose issues, along with probable causes and corrective actions.

• Technical Details: Connector pin assignments for various cable types and comprehensive product specifications (operating environment, power, physical dimensions, and certifications like CE, FCC, UL).
