B.4 Power Supply Unit
The power supply units of the SPARC M10-4/M10-4S and the crossbar box take
power from the input power and supply it to the system. The redundant configuration
of the power supply units allows the system to continue operating even if one of the
units fails during operation.
Table B-5 and Table B-6 list the specifications of the power supply units of the
SPARC M10-4/M10-4S and the crossbar box, respectively.
See the following chapters for details of the maintenance procedures:
