connectivity for the host. Host multimode termination is provided on the ESM card

Host SCSI Termination Power

Host termination power is not provided by the ESM.

The SCSI host channel senses termination power. If termination power goes below
3 volts, the interface chip will be disabled. This prevents data transfers if termination
power is lost from the host.
