System Attention LED

The attention indicator is represented externally by an amber LED on the operator panel and the back of the system unit. It is used to indicate that the system is in one of the following states:

￿Normal state: LED is off.

￿Fault state: LED is on solid.

￿Identify state: LED is blinking.

Additional LEDs on I/O components, such as PCI-X slots and disk drives, provide status information such as power, hot-swap, and need for service.

Concurrent Maintenance

Concurrent Maintenance provides replacement of the following parts while the system remains running:

￿Disk drives

￿Cooling fans

￿Power Subsystems

￿PCI-X adapter cards

3.3Manageability

Functions and tools that are provided for IBM Sserver p5 systems are described in the following sections.

3.3.1 Advanced System Management Interface

With the system in power standby mode, or with an operating system in control of the machine or controlling the related partition, the SP is working and checking the system for errors, ensuring the connection to the HMC for manageability purposes.

With the system up and running, the SP provides the ability to view and change the power-on settings using the Advanced System Management Interface (ASMI). Also, the surveillance function of the SP is monitoring the operating system to confirm that it is still running and has not stalled.

Figure 3-2 on page 61 shows an example of the ASMI accessed from the Web browser.
