The provided text explains the installation procedure for performing a firmware upgrade on the 3500/20 Rack Interface Module (RIM) in the 3500 Monitoring System. Here’s a summary of the key points:

Data Manager I/O Modules:

  • Must be installed behind the Power Supplies between the Power Input Modules and the Rack Interface I/O Module.
  • Connects the 3500 rack to TDIX or DDIX Communication Processors.
  • Each port can connect up to 24 channels to the Communication Processor.
  • Static and dynamic information is transferred from different ports to corresponding connectors on the Communication Processor.

Verification of Operation:

  • The Rack Interface Module and I/O modules can be installed or removed with power applied, following the Rack Installation and Maintenance Manual.

RIM Host Port Test Utility:

  • Used to verify that HOST ports on the Rack Interface Module and Rack Interface I/O Module are operating properly.
  • Requires Cable 130118-XXXX-XX (Host to 3500 Rack RS-232 Interface Cable) connected between the Configuration Port connector and the computer.
  • Refer to the 3500 Monitoring System Rack Configuration and Utilities Guide and Rack Configuration Software for details.

Firmware Upgrades:

  • Occasionally necessary to replace the original firmware in the 3500/20 Rack Interface Module.
  • The procedure involves removing the existing firmware and replacing it with upgrade firmware.
  • Required items: Large Flathead Screwdriver, Grounding Wrist Strap, Small Flathead Screwdriver, and Upgrade Firmware IC.
  • Refer to Section 7 (Ordering Information) for part numbers.

Installation Procedure:

  1. Ensure Rack Interface Module’s configuration is saved using the 3500 Rack Configuration software.
  2. Follow handling and storing considerations (refer to Section 1.2).
  3. Remove the RIM from the 3500 rack.
  4. Remove the Top Shield from the RIM.
  5. Remove the original firmware IC from the RIM PWA.
  6. Install the upgrade firmware IC into the socket on the RIM PWA.
  7. Replace the RIM Top Shield.
