Chapter 1 — Library Overview

IBRARY OWER
The library includes dual AC power inputs. The standard configuration
uses only one of these inputs. The 2N power supply redundancy option,
which must be purchased separately, uses both inputs. Connecting each
AC input to a separate circuit provides failover protection in the event of a
power failure in one of the circuits. The failover feature requires the 2N
power redundancy option.
The power supply bay, located between the two AC power inputs,
accommodates two sets of three power supply modules. The power supply
modules convert the AC input power to DC power for the drives and QIP
installed in the DBAs. The standard configuration uses one power supply
module per DBA. A second power supply per DBA, in combination with
the dual AC power inputs, provides 2N redundancy and failover
protection. The power supply modules needed for the 2N power
redundancy configuration are an option you can purchase separately or
when you order the library.

Note: Any slots that do not have power supply modules installed have
covers installed to maintain proper air circulation through the
library.
Each set of three power supply modules has its own main AC power
connector. The AC switch above the connector turns the main AC
power to the power supply modules on and off.
