Where Should The Scsi Terminator Be; Step 6: Attach Power And Scsi Cables - HP StorageWorks Ultrium 232i Getting Started Manual

Step 6: Attach power and SCSI cables

To support the high performance of the tape drive it is important to use a suitably-rated SCSI
cable.
1
Check your server or HBA documentation to ensure that the SCSI bus and cabling supports up
to Ultra 160 bus speeds. We recommend that you attach the SCSI ribbon cable supplied with
the tape drive to the SCSI host bus adapter.
2
Attach a spare power cable from the server's internal power supply to the power connector, as
shown in Figure 7, item 1.
3
Attach a spare connector on the server or HBA's SCSI ribbon cable to the SCSI connector of
the drive, as shown in Figure 7, item 2.
4
If the drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated
correctly
Daisy-chaining two devices is not recommended. If you do so, do not mix drive families (only
daisy-chain with other Ultrium tape drives) and do not put drives on the same bus as any Ultra
320 device, such as the Ultrium 960 tape drive
types," on page 9

Where should the SCSI terminator be?

Termination must be present at two and ONLY two positions on the SCSI bus—at the
beginning of the SCSI bus and at the end of the SCSI bus. Termination is normally enabled
by default on the HBA and most internal SCSI cables have a terminator attached. This will
usually be a small, rectangular block of plastic attached to the cable end and marked 'SCSI
Terminator'.
Therefore, assuming the HBA is the first device on the bus, you should check that the second
terminator is placed after the last device, as shown in Figure 7, item 2.
