1. With ten screws from the backplane screw packet (P/N: 70-331900-102), attach
the backplane to the bracket in the chassis as shown in the diagram.
2. To support a second backplane, affix three hex copper spacer pins.
3. Next secure both ends of the backplane with two screws on both sides of the
outer chassis.
4. Repeat steps 1-3 for remaining backplane assemblies.
5. For the topmost assembly, use the three hex copper spacers without the pins to
cap it off.
6. Connect the LED cable from backplane (JP1) to LED board. The lower one
connects to the 1U LED connector (J1) on the LED board; the middle one to the
2U connector (J2); and the upper one to the 3U connector (J3).
7. Now connect the Big 4p power cable from the PSU to the power connectors (J7
and J8) on the SCSI backplane.
8. Connect the fan connector to the fan pin header of the upper backplane to finish
the installation, and check to see the fan sensor is enabled.
