Note – The internal fault indicator system is powered by a capacitor. Therefore, once
you remove the server module from the chassis, the server module has a limited
operational timeframe.

To Troubleshoot Using the Internal Fault
Indicator LEDs
1. Place the server in standby power mode.
The Power/OK LED blinks when the server is in standby mode.
2. Remove the server from the chassis (see “To Remove the Server Module From the
Chassis” on page 3-13 ).
Set the server on an anti-static surface.
3. Remove the top cover of the server module (see “To Remove the Main Cover” on
page 3-15
).
4. Locate the blue Remind button on the motherboard (see
FIGURE 3-6
)
.
5. Press the Remind button.
If a DIMM or CPU has a fault, its LED will blink. See
FIGURE 3-6
for the location of
the internal Fault Indicator LEDs. Each LED has two states: blinking or off (see
TABLE 3-7
).
Note –
The Remind button charging circuitry can maintain operation for 30 - 45
minutes. To recharge the circuit, insert the server module in the chassis for
approximately 5 minutes.
