Figure 8-5 is a front view of the RFL 9508D Digital Chassis with its front door open. A drop/insert
chassis will look the same, except for the addition of a second CM4 common module in slot 1. The
main power supply module and the CM4 common module are expanded to show the location of all
front panel switches, indicators, and jacks. A functional description of switches, indicators, and jacks
for the Main Power Supply module appears in Table 8-2. The numbers in the item column of this table
