Introduction
This publication describes the replacement procedure for the CPU switcher card and Class B motherboard used in 4100U and 4100ES redundant
master controller configurations. The CPU switcher card is located in the primary CPU bay and allows for a second CPU daughter card, or master
controller, in an expansion bay. The Class B motherboard is located in the expansion bay and houses the secondary CPU daughter card.
There are two main sets of procedures in this document: one for replacing the CPU switcher card and one for replacing the Class B motherboard.
These procedures can be used separately, for replacing only one of the cards mentioned above, or in sequence, for replacing both cards.
