to the alternate power feed if the incoming voltage is lost. Dual ac power is available when
you order feature code 1901.

Power structure of the TS3500 Tape Library
Enhanced frame control assembly
This section describes the enhanced frame control assembly of the TS3500 Tape Library.
The enhanced frame control assembly is a power structure that combines drive power,
library power, and dual ac line cord capabilities. The assembly includes only two power
supplies, dual ac line cords, and a Medium Changer Assembly (MCA) unit.
The enhanced frame control assembly comes standard with Models L23 and L53, and can be
ordered as a feature code for Models D23 and D53. For two or more frames that are
properly configured, the assembly is constructed such that failure or repair of a single,
particular part does not cause the entire system to fail or require scheduled downtime for
maintenance. For example, the replacement of any single, failed power supply can be
accomplished without affecting the operation of the library. The two redundant power
supplies are fed directly by independent, dual ac line cords that support only 220 V ac (110
V ac is not supported). The dual ac line cords come standard on Models L23, D23, L53, and
D53, and do not need to be ordered as an additional feature code.
If dual ac line cords are not desired, both power supplies can be fed by a single customer
outlet by using feature code 1909 (Single Power Source Bifurcated Cable), however, feature
code 1909 cannot be used if feature code 1950 (Power Distribution Unit) is installed in the
same frame.
The enhanced frame control assembly is compatible with the following model conversions,
which must be performed by an IBM Service Representative:
•
Model L22 to L23
•
Model D22 to D23
•
Model L52 to L53
•
Model D52 to D53
•
Model L23 to L53
•
Model D23 to D53
•
Model L53 to L23
