5.4.2 Functional
Description
Two Dual SP3 units, each comprising a front and a rear circuit module,
are located near the center of the shelf (slots 9 and 13) and provide full
1+1 redundancy for critical processing resources for true non-stop
operation. SP3 requires a rear SP3 module, 89-0417, and Midplane III
(chassis 85-3007 or 85-3008).
