5.1.3 External Memory Device

The 6-HDD Expander SAS HSBP contains a non-volatile 8 Mbit Serial SPI FLASH Memory for

Boot and Run-Time/Configuration code storage. The device resides on the SPI interface of

VSC7161* SAS Expander.

The Serial SPI Flash memory operates from the 3.3 V rail.

5.1.4 LEDs

The 6-HDD Expander SAS HSBP contains a green STATUS LED and amber FAULT LED for

each of the six hard disk drives. The SAS/SATA hard drive drives the STATUS LED. The

FAULT LED is driven by the VSC410* controller whenever a condition, as defined by the

firmware, is detected.
