Installation
Auto-Termination
Auto-termination is disabled when a shunt is installed over both pins on
the TP2 pinset. To enable auto-termination, remove the shunt entirely or
move it to only one of the pins. The result must be open pins, as shown
in Figure 14. Verify that auto-termination is enabled on the host system.
For other HBAs, check the documentation for your particular host bus
adapter.
