3. Reinstall the shuttle into the chassis (see Section 3.15.4).
4. Reconnect the power cords and any cables that were removed.
5. Reinstall the compute nodes into the chassis (see Section 3.1.2).
6. Power on all the compute nodes.
3.18 Replacing the Power Distribution Module (PDM)
The Power Distribution Module (PDM) field replaceable unit (FRU) consists of the shuttle sheet metal cage,
four empty PCIe* cassettes, and a printed circuit board mounted under the system fans in the system shuttle
assembly. Replacing the PDM consists of removing all components of the shuttle and returning the PDM
board, empty PCIe cassettes, and shuttle cage.
3.18.1 Preparing to Remove the PDM
Before removing the PDM, perform the following procedure:
1. Turn off all compute nodes and peripheral devices.
2. Disengage all compute nodes from the chassis (see Section 3.1.1).
3. Disconnect the power cords and all external cables from the rear of the chassis.
4. Remove the shuttle from the chassis (see Section 3.15.1).
