Interconnecting Cards - Simplex 4100ES Installation Manual

23.5 Step 4. Interconnecting Master Controller Bay Cards
Each card has to be interconnected with every other card in the master controller bay. Read this section to ensure that cards are
interconnected.
23.5.1

Interconnecting Cards

Use the following instructions and Figure 140 to interconnect master controller bay cards.
1. Use the 733-659 Harness to connect P14 on the UPS to P3 on the master controller motherboard. Note that the P3 connector
has eight pins. Insert the harness connector on either the top four pins or the bottom four pins, not in the middle.
2. Use 733-672 Harness to connect P4 on the UPS to P2 on the master controller motherboard. Like the P2 connector, P3 has eight
pins. Insert the harness connector on either the top four pins or the bottom four pins.
3. If you are installing a new motherboard, orient the motherboard with the connector labeled J1 on the right and the header
labeled P1 on the left.
4. Slide the motherboard to the left until the pins are completely inserted in the connector of the previously installed motherboard.
5. Secure the motherboard to the chassis with four torx screws.
Important: The leftmost board must always be the master controller motherboard.
23.6 Step 5. Installing Motherboards into Expansion Bays
This section describes how to interconnect motherboards in expansion bays, and how to connect the expansion bays electrically to the
master controller bay.
23.6.1 Guidelines
Up to eight 2 (51 mm) x 11 ½-inch (292 mm) motherboards can be installed in an expansion bay. Adhere to the following guidelines when
installing a motherboard in an expansion bay:
• If a power supply is installed, it must be placed on the far right of the bay.
• Relay cards must be installed in the rightmost possible slots (just left of the power supply, if there is one). This is necessary to allow for
the proper routing of non-power limited wiring (typically 120 VAC wiring), which could be connected to a relay module.
• If a 4100/4120-0155 SDACT or a 4100/4120-0153 CCDACT is installed in the bay, it must be installed in the far left or far right slot.
Neither of these modules contains the J1 or P1 connectors, which are used to distribute power and communications to adjacent
modules.
