Remind button You can use the Remind button to place the front panel system-error light into the Remind mode. By pressing the button, you acknowledge the failure but indicate that you will not take immediate action. If a new failure occurs, the system-error light will turn on solid again. In the Remind mode the system-error light blinks every 2 seconds. The system-error light remains in Remind mode until one of the following situations occurs: v All known problems are resolved v The system is restarted v A new problem occurs You can use the Remind button to delay server maintenance until a later time. Also, resetting the system-error light enables the LED to react to another error. If the LED is still solid from the first error, it will mask additional errors. Integrated System Management Processor LED The xSeries 232 server has an Integrated System Management Processor feature on the system board. The green Integrated System Management Processor LED flashes, indicating that the system temperature, fan speeds, voltage ranges, power supplies, power backplane, and DASD backplane are being monitored. If an error occurs in any of these areas, the Integrated System Management Processor turns on the respective error LED on the Light Path Diagnostics panel. If the Integrated System Management Processor LED remains on or off, or if it blinks significantly faster than approximately once per second, then an error has occurred. See ″SP LED″ at "Diagnostic Panel LED" on page 109. Before you begin Before you begin to install options in the server, read the following information. v Become familiar with the safety and handling guidelines specified under "Handling electrostatic discharge-sensitive devices" on page 136, and read the safety statements on "Safety information" on page 133. These guidelines will help you work safely while working with the server or options. v You do not need to turn off the server to install or replace hot-swap power supplies, or hot-swap drives. v The orange color on components and labels in the server indicates hot-swap components. You can install or remove hot-swap components while the system is running, provided that the system is configured to support this function. For complete details about installing or removing a hot-swap component, see the information provided in this chapter. v The blue color on components and labels identifies touch points where a component can be gripped, a latch moved, and so on. v Make sure that you have an adequate number of properly grounded electrical outlets for the server, monitor, and any other options that you intend to install. v Back up all important data before you make changes to disk drives. v Have a small, flat-blade screwdriver available. v For a list of supported options for the server, refer to http://www.ibm.com/pc/us/compat on the World Wide Web.

Remind button
You can use the Remind button to place the front panel system-error light into the
Remind mode. By pressing the button, you acknowledge the failure but indicate
that you will not take immediate action. If a new failure occurs, the system-error
light will turn on solid again.
In the Remind mode the system-error light blinks every 2 seconds. The
system-error light remains in Remind mode until one of the following situations
occurs:
v
All known problems are resolved
v
The system is restarted
v
A new problem occurs
You can use the Remind button to delay server maintenance until a later time.
Also, resetting the system-error light enables the LED to react to another error. If
the LED is still solid from the first error, it will mask additional errors.
Integrated System Management Processor LED
The xSeries 232 server has an Integrated System Management Processor feature on
the system board. The green Integrated System Management Processor LED
flashes, indicating that the system temperature, fan speeds, voltage ranges, power
supplies, power backplane, and DASD backplane are being monitored. If an error
occurs in any of these areas, the Integrated System Management Processor turns on
the respective error LED on the Light Path Diagnostics panel. If the Integrated
System Management Processor LED remains on or off, or if it blinks significantly
faster than approximately once per second, then an error has occurred. See
