3.6.1.2.4 SCSI Bus Termination Power
Each host adapter that is connected to a DS-DWZZH-05 UltraSCSI hub
port must supply termination power (termpwr) to enable the termination
resistors on each end of the SCSI bus segment. If the host adapter is
disconnected from the hub, the port is disabled. Only the UltraSCSI bus
segment losing termination power is affected. The remainder of the SCSI
bus operates normally.
3.6.1.2.5 DS-DWZZH-05 Indicators
The DS-DWZZH-05 has two indicators on the front panel. (See Figure 3–4.)
The green LED indicates that power is applied to the hub. The yellow LED
indicates that the SCSI bus is busy.
