v
Hard disk drive (HDD) activity LED: When this LED is lit, it indicates that either of
the hard disk drives is in use.
v System locator LED: Use this blue LED to visually locate the server if it is in a
location with numerous other servers. If your server supports IBM Director, you
can use IBM Director to light this LED remotely.
v
Information LED: When this LED is lit, it indicates that a noncritical event has
occurred and is recorded in the error log. An LED near the failing component on
the system board is also lit to help isolate the error (see “Error LEDs” on page
20).
v
System-error LED: When this LED is lit, it indicates that a system error has
occurred. A system-error LED is also on the rear of the server. An LED near the
failing component on the system board is also lit to help isolate the error (see
“Error LEDs” on page 20).
USB connectors: Connect USB devices to these connectors.
Notes:
1. If you want to attach a keyboard or mouse to this server, you must use a USB
keyboard or a USB mouse.
After installing a USB keyboard, you might need to use the Configuration/Setup
Utility program to enable keyboardless operation and prevent POST error
message 301 from being displayed during startup. For detailed information
about this option and how to connect it to your server, see the documentation
that comes with the option. For information about the Configuration/Setup Utility
program, see “Using the Configuration/Setup Utility program” on page 9.
2. Use an external USB diskette drive if:
v You want to attach a diskette drive to this server.
v
You need to create an update diskette that contains the latest server firmware
code (see “Using the baseboard management controller firmware update
utility program” on page 11).
v
You need to create update diskettes that contain the latest server BIOS code
(see “Updating BIOS code” on page 21).
Hard disk drive status LEDs: When these LEDs are lit, it indicates that the
associated SCSI hard disk drive has failed. If an optional RAID adapter is installed
in the server and the LED flashes slowly (one flash per second), the drive is being
rebuilt. If the LED flashes rapidly (three flashes per second), the controller is
identifying the drive.
