13.3 Flash BIOS Memory

A Flash EEPROM resides on the SPI Bus for BIOS and configuration storage. A 16 Mbit device is utilized
for this function. The Flash memory permits the BIOS to be upgraded in the field. The Flash BIOS may
be write-protected by software

13.4 Drives

The PowerEdge R910 supports the new 2.5‖ hard drive carriers. These carriers implement new
industrial design to match the front bezel.
For the slots that are not occupied by drives, a carrier blank is provided to maintain proper cooling,
maintain a uniform appearance to the unit, and provide EMI shielding.
R910 supports diskless configuration.
Each hard drive carrier has two LED indicators visible from the front of the system. One is a green
LED for disk activity and the other is a bicolor (Green/Amber) LED for status information. The
activity LED is driven by the disk drive during normal operation. The bicolor LED is controlled by the
SEP device on the backplane. Both LEDs are used to indicate certain conditions under direction of a
storage controller.
