LED patterns
Table 4 describes the port side LEDs and their behavior.
Table 4. Port side LED patterns during normal operation
LED name
LED color
Status of hardware
Recommended action
Power status
No light
System is off or there is an internal
power supply failure
Verify the system is powered on (power
supply switches to
|
), the power cables
attached, and power source is live.
The unit may be faulty.
Contact IBM.
Steady green
System is on and power supplies are
functioning properly
No action required.
System status
No light
System is off or there is not power.
Verify the system is on and has
completed booting.
Steady green
System is on and functioning properly.
No action required.
Steady amber
(for more than
five seconds)
A system fault has occurred.
This LED displays steady amber
during POST, this is normal and does
not indicate a fault.
Check the failure indicated on the
system console.
Contact IBM.
Blinking amber
Attention is required. A number of
variables can cause this status
including single power supply failure,
a fan failure, or one or more
environmental ranges has been
exceeded.
Check the management interface and
the error log for details on the cause of
status.
Contact IBM.
Ethernet Speed
No light
Port speed is 10 Mbps.
No action required.
Steady green
Port speed is 100 Mbps
No action required.
Ethernet
Activity/Link
No light
There is no link.
Verify that the Ethernet cable is
connected correctly.
Steady amber
There is a link.
No action required.
Blinking amber
There is link activity (traffic).
No action required.
Optical media
port status (one
bi-color LED for
each FC port)
Off
No light or signal carrier on media
interface
Verify that the transceiver is installed
correctly and that the cable is connected
correctly.
Steady amber
Receiving light or carrier, but not
online.
No action required.
Slow blinking
amber (2 sec)
Disabled (by diagnostics or by
portDisable
command)
Verify that the diagnostic tests are not
being run. Re-enable the port using the
portEnable
command.
Fast blinking
amber (1/2 sec)
Port failure.
Check the management interface and
the error log for details on the cause of
the failure. Contact IBM Support if
necessary.
Steady green
Online.
No action required.
Slow blinking
green (2 sec)
Online but segmented (loopback cable
or incompatible switch)
No action required.
Fast blinking
green (1/2 sec)
Internal loop-back
No action required.
Flickering green
