Right Panel
The power subsystem fills up most of the right panel. It consists of a power
backplane and a metal rack that holds up to three 400-watt power supply
modules. The bottom compartment of the power supply rack can hold an
optional UPS module with battery and charger. The rear section contains the
three built-in power supply fans to cool down components and regulate air flow
inside each power supply. See Appendix C for details on the power subsystem.
The front panel board occupies the upper front section of the right panel. The
lower section has a second SCSI backplane board installation and another set of
seven hot-pluggable SCSI drive trays.
Figure 3-3 shows the components inside the right panel.
