Hot-Plug Fan
The hot-plug fan diagnostic LEDs indicate the condition of each fan in Compaq
ProLiant ML530 servers. If the front panel fan status LED is amber, check the individual fan
diagnostic LEDs to determine which fan has failed.
The hot-plug fan diagnostic LEDs can be viewed by removing the access panel of the server. To
remove the access panel, see “Access Panel” in Chapter 2. Figure 4-7 shows the location of the
hot-plug fan diagnostic LEDs. Table 4-7 identifies the diagnostic LED and describes the
condition of the fan.
To replace a fan, see “Fans” in Chapter 2. The color of the status and diagnostic LEDs resets
when the fan is replaced or system power is cycled.
