Tyco 4100U-S1 installation manual Expansion Bay Motherboard Placement

Step 5. Installing Modules into Expansion Bays, Continued

Placement Guidelines (continued)

•Motherboards can be installed on top of the PDI in expansion bays. The data and power that would normally be bussed via the PDI are routed across the motherboards via their left and right connectors (J1 and P1).

•Up to four 2” (51 mm) x 11 ½” (292 mm) motherboards can be installed in an expansion bay if the pins on the left connector (usually P1) on the leftmost motherboard are removed.

•Motherboards should be added from left to right, starting in slot 3.

•Relay motherboards must be the rightmost motherboards.

•The CPU motherboard generates the 8V supply required for 4100A motherboards. It also has the 4100A style Molex connectors to which a harness can be fitted as in Figure 2-6.
