Replacing the CPU Switcher Card
Introduction
The CPU switcher card is used in redundant master controller configurations to automatically switch the communications bus and city circuit from
a primary CPU card to a backup (secondary) CPU card when a trouble is detected by the 24-point I/O card. The CPU switcher card is located in the
Primary CPU Bay, the top bay in the back box.
The card layout within the Primary CPU Bay is different than that of a normal CPU bay. The CPU motherboard and daughter card, for instance, are
installed at the far left of the bay, rather than the right. Also, the network card slot on the CPU motherboard must not be used in redundant master
controller configurations. Immediately to the right of the primary CPU motherboard is the CPU Switcher Card and then the 24-point I/O card. Figure 1
shows a sample layout of a Primary CPU bay within a 4100U configured with a redundant master controller.
Removing the switcher card involves removing system power, detaching the two connectors from the card (at P3 and P4), and removing the four Torx
screws that fasten the board to the standoffs at the rear of the bay. However, because the switcher card is mounted in between other cards in the bay,
the CPU motherboard must also be removed to make it possible for the switcher card to be disconnected from the adjacent cards.
Figure 1: Primary CPU Bay Layout
Remove Power and Access the Primary CPU Bay
1. Disconnect any connection to the batteries at the PDM and then remove the power to the system at the breaker.
2. Lower the front door to the Primary CPU Bay (the top bay in a redundant master controller configured panel). Refer to Figure 1 for the
location of the CPU switcher card and CPU motherboard within the bay.
Remove the CPU Motherboard
The CPU motherboard must be removed from the bay before the CPU switcher card can be removed. Follow the steps below to remove the CPU
motherboard from the Primary CPU Bay.
1. Label and detach the service port and front display ribbon cables from the CPU daughter card, which is mounted to the CPU motherboard.
The service port cable is the thinner of the two ribbon cables.
2. Release and lower the card stabilizer at the front of the bay by pressing in the tabs at either end of the stabilizer. The card stabilizer must be
lowered before cards can be removed.
3. Pull the CPU daughter card out of its slot on the CPU motherboard and set it aside.
The next few steps involve the labeling and removal of cables connected to the CPU motherboard. You will be reattaching these cables later.
The locations and suggested labels of the connections are shown in Figure 2.
4. Label and disconnect any plug connected to P1 on the CPU motherboard.
5. Label and disconnect any plugs connected to P4, P5, or P6.
6. Label and disconnect any plugs connected to P7 and P8.
7. Label and disconnect any wires connected to TB3. Include as part of the label the name of the terminal block and the specific terminal the
wire connects to.
8. Label and disconnect any wires connected to the eight-position terminal block. Include as part of the label the name of the terminal block
and the specific terminal the wire connects to.
Note: TB2, the RUI terminal on the CPU motherboard, is not used in redundant master controller configurations. Instead, use 567-217 RUI.

9. Remove the six Torx screws that fasten the motherboard to the standoffs at the rear of the CPU bay and set them aside for later use. The
location of each screw is shown in Figure 3.
Figure 3: CPU Motherboard Screw Locations
Note: Leave the standoffs fastened to the rear of the CPU bay. You will attach the replacement motherboard to these same standoffs.
10. Disconnect the J1 header connector on the CPU motherboard from the P1 header connector on the CPU switcher card to completely detach
the CPU motherboard.
11. Set the board aside. You will reinstall it after the new CPU switcher card is installed.
Remove the Existing CPU Switcher Card
1. Label and remove the two connectors connected to the CPU switcher card. Label the 18-position plug, located towards the top of the card,
“P3”. Label the 14-position plug closer to the bottom of the card “P4”. Refer to Figure 1 for the locations of these connections.

Replacing the Class B Motherboard
Introduction
The class B motherboard is located in the Secondary CPU bay. The motherboard houses the secondary CPU card and mounts to the far left of the
Secondary CPU bay (see Figure 4).
Note: Actually, a full-length motherboard cannot be mounted in the left-most slot of an expansion bay; that slot must remain empty so that the wires
connected to the PDI are easily accessible. The class B motherboard is, however, the card mounted furthest to the left in the bay. Refer to Figure 4 for
the location of the board.
Removing the class B motherboard involves removing all wiring attached to the board, uninstalling the CPU daughter card mounted to the board, and
unscrewing the four Torx screws that fasten the board to standoffs at the rear of the bay.
