Applying Power To The Drive - HP Surestore Tape Library Model 10/180 Installation Notes

Applying Power to the Drive

To apply power to the LTO tape drive, follow these steps:
1. When you are finished installing all drives, place the LTO drive power switch to the on
(|) position for each drive.
2. Set the library power switch to the ON position.
3. Verify that all drives power on (you should feel air flowing from the fan).
SCSI Drive Connections
For SCSI operation, make sure that you comply with the length restrictions for your
channel type.
It is very important to label each drive with its host address. It is also important to label the
cables. These labels provide reliable identification for any future maintenance on the
drives.
CAUTION: Do not connect SCSI cables to the drives until they are configured for
operation.
Direct Connection
For installations requiring SCSI direct data path configurations, for each drive:
1. Open the left rear door.
2. Connect the host data cable to the appropriate connector at the rear library frame for
the first drive.
3. Make sure that a terminator is installed on the second drive connector at the rear library
frame.
Daisy-Chain Connection
Note: For maximum performance, HP recommends only one drive in the chain.
For installations requiring SCSI daisy-chain data path configurations:
1. For the 20/700 tape library, open the left and right rear doors; for the 10/180 tape
library, open the rear door
2. Connect the host data cable to the appropriate connector at the rear library frame.
3. At the rear of the library frame, install a short SCSI jumper cable from the second
connector of the first device to the next device connector in the chain.
4. Make sure that a terminator is installed on the last device connector on the rear library
frame.
