Internal Diagnostic LEDs
The server is equipped with a SuperCap voltage source that can activate internal component fault LEDs
up to one half-hour after AC power is removed. The server has internal fault LEDs for fan modules and
DIMMs.
To use these LEDs to identify a faile
d component, press the front or rear Identification button (see
Figure 1-8 or Figure 1-9) with AC power removed. An LED lights amber to indicate a failed component.
See Figure 1-10 for the locations of these internal LEDs.
