HP ProLiant DL2000 server technologies

Fans and fan control

Standard fan configuration for the e2000 chassis includes four, 80-mm non-hot-plug fans. If a fan

fails, the DL2000 implements fan zoning and takes down only those nodes behind the fan. The

remaining nodes on the opposite side of the chassis continue to run. Each node sees only the two fans

that are directly in front of that node, allowing for greater uptime. Figure 6 illustrates thermal

management architecture in the DL2000.

Bezels and LEDs

Every node inc

ludes a health LED, UID (unit identification) LED, and power button on the back. Each

node also includes an individual power button and health LED on the front. Every chassis includes a

UID LED on the front. Health LEDs use different colors to indicate the node’s status. HP UID LEDs light

up to help you quickly identify the components in a rack. Figure 7 illustrates front bezel and LED

configurations.
