24 pSeries 610 Models 6C1 and 6E1 Technical Overview and Introduction
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 o f 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 LE Ds 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/6 000®. 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 appropria te policy flags are set) in the
following conditions:
򐂰Power is restored after a power loss during normal system operation.
򐂰Hardware Checkstop Failures.
