Power Considerations

In the L180 library, some combinations of input voltage and current, drive type,
and plug type, limit the number of drives that can be installed. See the
following paragraphs for details.

At 120 to 127 VAC

You may install the maximum number of drives in the L180 library if the power
source at the site is 120 to 127 VAC:
• 10 DLTs (with or without Power Factor Correction [PFC])
• 10 LTOs
• 6 StorageTek T9840s and one DLT drive
You may do so even if the library is connected to a single AC circuit.
Note: For partial drive column power redundancy, StorageTek recommends
