System information LED: When this amber LED is on, the server power supplies
are nonredundant, or some other noncritical event has occurred. The event is
recorded in the error log. Check the light path diagnostics panel or event log for
more information. This LED will remain lit until you resolve the problem or you press
the remind button. (See “Remind button” on page 34 for more information.)
System-error LED: When this LED is lit, it indicates that a system error has
occurred.
USB 1 and 2 connectors: Connect USB devices to these connectors.
DVD-eject button: Press this button to release a CD or DVD from the DVD drive.
Hard disk drive activity LED: When this LED is flashing, it indicates that the drive
is in use.
Hard disk drive status LED: On some server models, each hot-swap hard disk
drive has a status LED. When this LED is lit, it indicates that the drive has failed. If
an optional IBM ServeRAID adapter is installed in the server, when this LED is
flashing slowly (one flash per second), it indicates that the drive is being rebuilt.
When the LED is flashing rapidly (three flashes per second), it indicates that the
adapter is identifying the drive.
Note: For proper cooling, do not install any card in the slot next in sequence to a
ServeRAID adapter with battery backup module (for example, if a ServeRAID
adapter with battery backup module is installed in slot 2, do not install any card in
slot 3).
DVD drive activity LED: When this LED is lit, it indicates that the DVD drive is in
use.
