2.5 SCSI Bus Termination Power
Each host adapter 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.
2.6 DS-DWZZH-05 Indicators
The DS-DWZZH-05 has two indicators on the front panel (see Figure 2–1). The green LED indicates that power is applied to the hub. The yellow LED indicates that the SCSI bus is busy.
2.7 Configuring a Cluster with a DS-DWZZH-05
