You can use the Remind button to place the front panel system-error light into a
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 LED will turn on
again.
In the Remind mode, the system-error light flashes every 2 seconds. The
system-error light remains in Remind mode until one of the following situations
occur:
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 342 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

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 “Working
inside a server with power on” on page 41, “Handling static-sensitive devices” on
page 41, and “Safety information” on page 109. 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, hot-swap drives, hot-swap fans, or hot-plug PCI adapters.
v The orange color on components and labels in the server identifies hot-swap or
hot-plug components. This means that you can install or remove the component
while the system is running, provided that your system is configured to support
this function. For complete details about installing or removing a hot-swap or
hot-plug 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
