Table 1-4 on page 1-12
install in the L180 library if it is connected to a single 220 VAC circuit. Use this
table to determine:
• How many drives may be installed in the library.
• Whether the library's power cord requires a locking plug or might require a
locking plug in the future.
• Whether the library's configuration requires the optional PDU and a second
power cord or might require this equipment in the future.
• How many AC circuits the customer must supply for the library.

Notes:
1. Numbers in this table include library robotics requirements. StorageTek
recommends that site power be sized to accommodate expansion to the maximum
number of tape drives.
2. You must use a locking plug on the library's power cord when the library contains a
non-PFC DLT drive.
3. PFC power supplies have less leakage current and lower peak current demand on
the AC input.

1. All new DLT drives ship with the PFC power supply (85 W).
2. You must use a locking plug on the library's power cord when the
library contains a non-PFC DLT drive.
