Server controls, connectors, LEDs, and power This section describes the controls, connectors, and light-emitting diodes (LEDs) and how to turn the server on and off. Front view The following illustration shows the controls, LEDs, and connectors on the front of the server. Hard disk drive status LED Hard disk drive activity LED Electrostatic-discharge connector Operator information panel DVD-eject button DVD drive activity LED Hard disk drive status LED: If a ServeRAID-8i adapter is installed, when this LED is lit it indicates that the associated hard disk drive has failed. If 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. Hard disk drive activity LED: On some server models, each hot-swap hard disk drive has an activity LED. When this LED is flashing, it indicates that the drive is in use. Operator information panel: This panel contains controls and LEDs. The following illustration shows the controls and LEDs on the operator information panel. Power-control button Information LED USB connector Release latch Power-on LED Hard disk drive activity LED Locator LED System-error LED The following controls, connectors, and LEDs are on the operator information panel: v USB connector: Connect a USB device to this connector. v Power-control button: Press this button to turn the server on and off manually. A power-control-button shield comes with the server. v Information LED: When this LED is lit, it indicates that there is a suboptimal condition in the server and that light path diagnostics will light an additional LED to help isolate the condition. If the LOG LED on the light path diagnostics panel is lit, information is available in the baseboard management controller (BMC) log or in the system-event log about the condition. The condition might be that the BMC log is full or almost full. 8 IBM System x3850 Type 8864: User's Guide

This
section
describes
the
controls,

and
light-emitting
diodes
(LEDs)
and
how
to
turn
the
server
on
and
off.
Front
view
The
following
illustration
shows
the
controls,
LEDs,
and
connectors
on
the
front
of
the
server.

status
LED:
If
a
ServeRAID-8i
adapter
is
installed,
when
this
LED
is
lit
it
indicates
that
the
associated
hard
disk
drive
has
failed.
If
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.
Hard
disk
drive
activity
LED:
On
some
server
models,
each
hot-swap
hard
disk
drive
has
an
activity
LED.
When
this
LED
is
flashing,
it
indicates
that
the
drive
is
in
use.
Operator

panel:
This
panel
contains
controls
and
LEDs.
The
following

v
Information
LED:
When
this
LED
is
lit,
it
indicates
that
there
is
a
suboptimal
condition
in
the
server
and
that
light
path
diagnostics
will
light
an
additional
LED
to
help
isolate
the
condition.
If
the
LOG
LED
on
the
light
path
diagnostics
panel
is
lit,
information
is
available
in
the
baseboard
management
controller
(BMC)
log
or
in
the
system-event
log
about
the
condition.
The
condition
might
be
that
the
BMC
log
is
full
or
almost
full.
