Thick/Thin Ethernet Riser

Note: Follow the correct shutdown and power down procedure, and remove the Ethernet riser card from the system unit.

The thick/thin Ethernet riser card comes shipped configured for the thin (BNC) Ethernet interface. The configuration is set by two removable jumper blocks that fit over two of the three rows of pins that are located on the riser card. Follow these steps to change the configuration:

1.Pull each of the two jumper blocks off of the configuration jumper block.

2.Replace the two jumper blocks on the upper two rows of pins to configure for the thick connector, or on the lower two rows for the thin connector.
