PC/104 Card Stacking for SAGE RTU CPU Upgrades
Issue
Users need guidance on the correct stacking order of PC/104 cards when installing or upgrading the CPU in SAGE RTU units.
Product
SAGE RTU Product Line (models using PC/104 architecture, including C3414 CPU upgrades)
Environment
Utility substations or industrial automation systems where SAGE RTUs require CPU upgrades or additional PC/104 expansion modules.
Cause
Incorrect stacking of PC/104 cards can lead to clearance issues, improper connections, or malfunction of optional modules such as Ethernet or GPS.
Resolution
When stacking PC/104 cards:
- Place the CPU card on top of the stack for standard installations.
- If installing the C3463 Ethernet 5-Port Switching Hub, it must be placed on top of the CPU card due to clearance restrictions.
- Other optional cards (e.g., C3461 GPS, C3830 Analog Input, C3831 IRIG-B, C3437 Communication Expansion) should be stacked below the CPU card in any order, except where noted.
- Ensure all connectors are properly aligned and secured using the provided mounting hardware.
