Mapping between Subracks and
DC PDUs
•
For the T64 Enhanced subrack, the PIU boards installed back-to-back are in mutual backup.
•
For the T64 General, T32, and T16 subracks, PIU boards on the left and right sides are in
mutual backup.
•
For the universal platform subracks, the PIU boards are installed on the right side and the
upper and lower PIU boards are in mutual backup.
•
For details of the backup relationships between PIU boards, see the "Power Redundancy"
section.
