The following LEDs are on the operator information panel: v Hard disk drive 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. 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. USB connectors: Connect a USB device to either of these connectors. Important: If a Remote Supervisor Adapter II is installed in the server, the USB 1 connector is disabled. Notes: 1. If you want to attach a keyboard or mouse to this server, you must use a USB keyboard or a USB mouse. For detailed information about the USB keyboard and how to connect it to your server, see the documentation that comes with the USB keyboard. 2. The server supports keyboardless operation. If a USB keyboard is not connected to the server, when the server is turned on or restarted, error message 301 will appear during POST. No action is required. POST will continue within one minute. 3. You must 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 baseboard management controller firmware (see "Using the baseboard management controller firmware update program" on page 14). v You need to create update diskettes that contain the latest server BIOS code (see "Updating the BIOS code" on page 27). Hard disk drive status LEDs: On some server models, each hot-swap hard disk drive has a status LED. If the status LED for a drive is lit continuously, that individual drive is faulty. The interpretation of a flashing status LED depends on the SCSI controller that is connected to the hot-swap drive, as follows: v When the drive is connected to the integrated SCSI controller with RAID capabilities, a flashing status LED indicates that the drive is a secondary drive in a mirrored pair and the drive is being synchronized. v When the drive is connected to an optional ServeRAID™ controller, a slowly flashing (one flash per second) status LED indicates that the drive is being rebuilt. When the LED is flashing rapidly (three flashes per second), it indicates that the controller is identifying the drive. 6 326m Type 7969: Hardware Maintenance Manual and Troubleshooting Guide

The
following
LEDs
are
on
the
operator
information
panel:
v
Hard
disk
drive
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.
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.
USB
connectors:
Connect
a
USB
device
to
either
of
these
connectors.
Important:
If
a
Remote
Supervisor
Adapter
II
is
installed
in
the
server,
the
USB
1
connector
is
disabled.
Notes:
1.
If
you
want
to
attach
a
keyboard
or
mouse
to
this
server,
you
must
use
a
USB
keyboard
or
a
USB
mouse.
For
detailed
information
about
the
USB
keyboard
and
how
to
connect
it
to
your
server,
see
the
documentation
that
comes
with
the
USB
keyboard.
2.
The
server
supports
keyboardless
operation.
If
a
USB
keyboard
is
not
connected
to
the
server,
when
the
server
is
turned
on
or
restarted,
error
message
301
will
appear
during
POST.
No
action
is
required.
POST
will
continue
within
one
minute.
3.
You
must
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
baseboard
management
controller
firmware
(see
“Using
the
baseboard
management
controller
firmware
update
program”
on
page
14).
v
You
need
to
create
update
diskettes
that
contain
the
latest
server
BIOS
code
(see
“Updating
the
BIOS
code”
on
page
27).
Hard
disk
drive
status
LEDs:
On
some
server
models,
each
hot-swap
hard
disk
drive
has
a
status
LED.
If
the
status
LED
for
a
drive
is
lit
continuously,
that
individual
drive
is
faulty.
The
interpretation
of
a
flashing
status
LED
depends
on
the
SCSI
controller
that
is
connected
to
the
hot-swap
drive,
as
follows:
v
When
the
drive
is
connected
to
the
integrated
SCSI
controller
with
RAID
capabilities,
a
flashing
status
LED
indicates
that
the
drive
is
a
secondary
drive
in
a
mirrored
pair
and
the
drive
is
being
synchronized.
v
When
the
drive
is
connected
to
an
optional
ServeRAID
™
controller,
a
slowly
flashing
(one
flash
per
second)
status
LED
indicates
that
the
drive
is
being
rebuilt.
When
the
LED
is
flashing
rapidly
(three
flashes
per
second),
it
indicates
that
the
controller
is
identifying
the
drive.
