Installing a redundant power supply
If you have a redundant power supply for the MSL4048, MSL8048, or MSL8096 tape library,
you can install it now or wait until the installation process is complete.
To install the redundant power supply:
1. Verify that the power to the library is off and the power cord is not attached.
2. On the back of the library, locate the second power supply bay, which is right above the
existing power supply.
3. Using a #2 Phillips screwdriver, remove the screws that attach the bay cover to the chassis.
4. Position the new power supply on the alignment rails and push it into the library until it is flush
with the back panel, as shown in Figure 44 (page 50).

5. Tighten the blue thumbscrews by hand to secure the power supply to the chassis as shown in
Figure 45 (page 50).

Changing the SCSI address (parallel SCSI drives only)
On a parallel SCSI device, if you need to change the SCSI ID for one or both of the tape drives,
do so before connecting the library to the host computer.
The pre-configured SCSI address for all full-height tape drives in the MSL2024 and MSL4048, and
for all drives in the MSL8048 and MSL8096 is 4. For half-height drives in the MSL2024 and
MSL4048, the bottom drive of any pair has SCSI address 4 and the top drive has SCSI address
