Product Description Each BCC provides two LVD SCSI ports (B in Figure 5) for connection to the controller enclosure. The EEPROM on each BCC stores 2 Kbytes of configuration information and user-defined data, including the manufacturer serial number, World Wide Name, and product number. The following are additional features of the BCC: • LEDs (C in Figure 5) show the status of the BCC and the bus. • A rotary switch (D) used to set the enclosure (tray) ID which is used by internal controller operations, and also by the management tools to identify each enclosure. • DIP switches set disk enclosure options. The only option used by the Disk Array FC60 is the full-bus/split-bus mode. • Screws (F) prevent the card from being unintentionally disconnected. • Cam levers (G) assist in installing and removing the BCC from the enclosure, ensuring a tight connection with the backplane. BCC functions include drive addressing, fault detection, and environmental services. Disk Enclosure Components 27
