Figure 3-6. Terminating Power—Seagate and IBM Ultrium Drives (C67295)
1. Seagate drive—shown with terminating power ON
2. IBM drive—shown with terminating power ON (The four jumpers - counting from right to left - are
address jumpers that must be in place for library operation. Terminating power is the fifth jumper -
counting from right to left)
Note: HP drive not shown. Terminating power is always ON and can not be changed.
CAUTION:
Loss of data or degradation of performance: StorageTek recommends
that the devices at both ends of the bus supply terminating power.
Industry standards advise that no more than three devices provide
terminating power to the bus.
8. Verify whether TERMPWR for the drive is on or off (enabled or disabled) for
each IBM LTO drive and Seagate LTO drive. If necessary, move the jumper
to match the customer's requirement. Then replace the drive tray cover.
• TERMPWR On: Install the jumper on the pins as shown.
