You can access the indicator panel without any tools. The panel provides enough information to identify the area that needs attention. The panel contains a group of amber LEDs that indicate which functional area of the system is experiencing the fault (such as Power, Processor cards, Memory, or Fans). If one of these LEDs is on, the user or service representative is directed to the physical area of the server, where they will find an additional LED on, indicating that the component is responsible for the current fault.
In addition to the indicator panel or display, individual LEDs are located on or near the failing components. The LEDs are either on the component itself or on the carrier of the component (memory card, fan, memory module, or processor card(s)). The LEDs are amber, except for the power supplies. For the power supplies, two green LEDs indicate the fault condition for the power supply.
Figure 3-2 on page 24 shows the LEDs on the system indicator panel, which is located inside the server.

3.2.2 Service processor
The Models 6C1 and 6E1 have an integrated service processor, located on the system board. When the system is powered down, but still plugged into an active power source, the service processor functions are still active under standby power. This function provides enhanced RAS by not requiring AIX® to be operational for interfacing with a system administrator or service agent for pSeries™ or RS/6000®. All service processor menu functions (using the local, remote, or terminal concentrator console), as well as dial out capability, are available even if the system is powered down or unable to power up. The next sections describe selected features of the enhanced service processor.
Automatic reboot
The system is designed to automatically reboot (if the appropriate policy flags are set) in the following conditions:
Power is restored after a power loss during normal system operation.
Hardware Checkstop Failures.
