Hot-Plug Fan LED Indicators
The ProLiant DL740 server ships with two hot-plug fans. Fan 1 is closest to the front of the
server. Each fan has an arrow-shaped status LED that indicates the status of the fan the arrow
is pointing to. Figure 7-13 shows an example of the hot-plug fan status LEDs:
• Hot-plug fan 1 LED (1)—In this case, the LED is amber, which means that the fan needs
attention or is not installed.
• Hot-plug fan 2 LED (2)—In this case, the LED is green, which means that the fan is
installed and working properly.

CAUTION: Never remove both hot-plug fans while the server is powered up. Overheating
and damage to hardware could result. If the appropriate HP software drivers are installed, the
operating system software will initiate a power shutdown if overheated.
NOTE: The hot-plug fan LEDs are not part of the fan housing. Figure 7-13 shows the LEDs as if the fan
were installed in the server.
