4100/4120-6014, 4100-6078 NICs and 4100/4120-Series Media Modules Installation Instruction
Dual fiber media jumper settings (746-109 only)
Use JW1 to adjust the link power budget. If communication problems occur, ensure the fiber connections comply with ANSI/TIA/EIA 568-C.3 or later
industry standards. A low power setting is preferred for all 62.5um fiber links less than 11 dB, and 50 um fiber links less than 6.6dB.
50/125 um fiber multi-mode
High setting: 17 dB
Medium setting: 11.6 dB
Low setting: 6.6 dB
Duplex fiber media diagnostics (566-1197, 566-1198, 566-1199, or 566-1200 only)
SW1 displays the diagnostics on the diagnostic LEDs. Press to display the type and thresholds reached.
• Hold for 3 seconds to toggle between the Normal and Advanced diagnostics mode.
• Hold for 6 seconds to clear the counters.
Note: If SW2-4 is set to advanced diagnostics, and if you press and hold SW1 for 3 seconds, the card does not toggle between the diagnostic modes.
The mode is set to advanced.
SW2 configures the diagnostics display and the offline test modes. Refer to 579-1233 for more information on 4120 Duplex Fiber Media Card
Diagnostics. Switch SW2 is a bank of four DIP switches. From left to right (see Figure 8), these switches are SW2-1 to SW2-4.
Position Description
1 Offline test mode
2 Fiber data loopback
3 Select normal/low thresholds to monitor diagnostic LEDs
4 Select normal / advanced diagnostics
Note: If either test mode (SW2-1 and/or SW2-2) is enabled, normal 4120 network traffic is disrupted.
Setting the NIC daughter card address
Switch SW2 on the 4100 NIC is a bank of eight dip switches. From left to right, see Figure 10, switches are SW2-1 through SW2-8. The purpose of these
switches is as follows:
• SW2-1. This switch sets the baud rate for the internal 4100 communications line running between the card and the 4100 CPU. Set this switch
to ON.
• SW2-2 through SW2-8. These switches set the card's address within the 4100 FACP. Refer to Figure 11 for a complete list of the switch
settings for all possible card addresses.
Note: You must set these switches to the value assigned to the card by the Programmer.
