4.3.2.5 External Memory Device
The 6HDD SATA HSBP contains non-volatile 32K and 64K Serial EEPROM devices for Boot
and Run-Time/Configuration code storage, respectively. These devices reside on the private I
bus of the GEM424 controller.
The SEEPROMs operate off the 5.0V rail and are housed in 8-pin small-outline integrated circuit
(SOIC) packages.
4.3.2.6 LEDs
The 6HDD SATA HSBP contains a green ACTIVITY LED and a yellow FAULT LED for each of
the six drive connectors. The ACTIVITY LED is driven by the GEM424 or, for drives that support
the feature, by the SATA hard drive itself whenever the drive is accessed. The FAULT LED is
driven by the GEM424 controller whenever an error condition, as defined by the firmware, is
detected.
