PMBus (SSI Power Control) Cable
This cable sends PMBus signals between the power supplies and the baseboard. It is soldered on the PDB side and connects to
the baseboard PMBus connector (J9E1) on the other end.
For the location of the PMBus connector on the baseboard, see Figure 12: Cable Routing" in (E) in Chapter 4.
To reconnect the PMBus cable:
1. Run the cable across the cable bundle bracket and connect it to the baseboard.
2. Re-cover with the black insulator covering (if present).
CPU 1 and CPU 2 Power Connectors
The CPU1 and CPU2 power cables bring power from the power distribution board to the CPUs (and their DIMMs).
Both cables are soldered to the PDB and only have connectors on the baseboard side.
The CPU1 cable connects to the baseboard at the front of the board near the CPU1 DIMMs, (
The CPU2 cable is routed through another black insulator along the right chassis wall to a connector at the rear right side of the
board, (CPU_1_PWR, J9A2).
For the locations of these cables, see Figure 12: Cable Routing" in (E) in Chapter 4.
To reconnect the CPU1 and CPU2 power cables on the baseboard:
1. Run the cable bundles across the cable bundle bracket and connect them to the baseboard. (Figure 57)
2. Re-cover the black insulator covering the CPU 1 and CPU 2 power cable bundles in the cable bracket (if present).
