Optic Fiber Interface Modules For Single-Mode Fibers; Troubleshooting - SOHARD SH ARC-PCIu Handbuch

Handbuch / Manual
Important: When no fiber is plugged into the interface module the
receptacles must be protected by suitable covers to prevent dissipating
light from interfering the network.

10 Troubleshooting

• The card is accessible, but no interrupts are generated.
Possible cause: An insufficient number of interrupt lines are reserved for
PCI by the BIOS of the PC.
Solution: Configure more interrupts for PCI in the BIOS setup.
• The Receive LED indicates Reconfigurations.
Possible causes:
- Only one node is present in the network
- The network is not properly terminated
- At RS485 connections DATA-A and DATA-B are swapped
