BCM400 advanced function tray (AFT)
The advanced function tray (AFT) houses the hard disk and an extra, unpopulated bay. The
standard configuration contains a single hard disk and has no RAID LED display. The AFT, in the
RFO configuration contains two hard disks, a RAID controller card and has an LED display to
monitor RAID status. The extra, unpopulated bay is reserved for future development. The
advanced function tray mounts in the upper BCM400 platform base chassis bay. The advanced
function tray slides out and away from the front of the chassis for hard disk maintenance, RAID
upgrade or exchange purposes.
Figure 8 illustrates the advanced function tray chassis and faceplate interfaces for the BCM400
standard (STD) and redundant feature option (RFO) platform configurations.
