individual leds are located on or near the failing components. the leds are located either on the component itself or on the carrier of the component (for example, memory card, fan, memory module, or cpu). leds are either green or amber.
green leds indicate either of the following:
1 electrical power is present.
2 activity is occurring on a link. (the system could be sending or receiving information.)
amber-colored leds indicate a fault or identify condition. if your system or one of the components on your system has an amber-colored led turned on or blinking, identify the problem and take the appropriate action to restore the system to normal.
the following table identifies the location, color, and status of your system component leds.

the following illustration shows the ethernet led locations on the rear of the model 6c4 and model 6e4.

the following illustration shows the rio connector led locations on the rear of the model 6c4 and model 6e4.

the following table explains the meaning of the on and off status of the pci-x adapter leds.

reporting the problem
after you have determined which component is failing, report the problem.
1. record the following information before calling for service:
1 machine type and model number
2 server serial number
3 any error codes that appear in the operator panel display or console
4 the adapter or device containing the lit amber-colored led
2. call for service. you will be given the choice to replace the failing component yourself or have a service representative replace it for you. if you decide to replace the failing component, go to “repair action” on page 17 for instructions.
repair action
after you have determined which component is failing, a repair action is necessary.
if you need instructions on component installation, removal, and replacement, see 2installing options in the model 6c4 and model 6e42 located in the eserver pseries 630 model 6c4 and model 6e4 installation guide.
1. run the system verification procedure, see chapter 7, “verifying the hardware operation”, on page 123.
2. record the following information before calling for service:
1 machine type and model
2 server serial number
3 any error codes that appear in the operator panel display or console
4 any leds that are lit on the operator panel
3. call for service.
4. after the repair action is completed, go to “resetting the leds”.
