The flash memory card conforms to the Personal Computer Memory Card
International Association (PCMCIA) standard 1.0. The flash memory card is the
read/write media for the flash memory drive. The drive supports a 10 or 20 MB
card.
The four green LEDs (which are only visible with the cover off the 4- and 8-Slot
chassis, and the bezel off the Extended chassis) provide information about the
status of the flash memory drive. The LEDs are identified on the board as LEDs
CR2 through CR5. They are used during power-on self-tests to indicate test
completion status.
The LEDs are also used during normal operation to indicate channel status.
When a hardware reset takes place, all four LEDs automatically light. See
Table 3-1 for more information.
