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

2

C 

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.
