DescriptionObservation of the LED status indicators can provide essential diagnostic information in the event of a problem occurring. This document will provide an explanation of the definition and function of the LEDs for each of the core FRUs of the Sun[TM] Netra CT 900. These being the Shelf Manager Modules (ShMM), the Switch Node Boards, the Shelf Alarm Panel (SAP), and the Power Entry Modules (PEM)
For the definition of the LEDs on each individual Server Node Board, refer to the relevant service manual in the customer documentation available at
http://docs.sun.comSteps to FollowCheck all of the LEDs for unusual condition. Description of the meaning of
each of the LEDs is given below.
For
location of the LEDs refer to the attachment ShMM.gif

The
LEDs on the ShMM fall into 3 categories

Description
|
|
Ethernet 0 Link Speed
|
Yellow
Green
|
This LED is normally
Yellow to indicate that the connection to the switch is
running at 100Mbps. If there is a problem across with the
connection, the link may reduce speed to 10Mbps and the LED will
turn Green. Ethernet port 0 on the ShMM is connected port 1
of the Base Network. The upper ShMM connect to the switch in slot
7, and the lower ShMM connects to the switch in slot 8.
|
|
Ethernet 0 Activity
|
Green
|
Any activity in the
switch Base Network will cause this green LED to Blink.
|
|
Ethernet 1 Link Speed
|
Yellow
Green
|
By default there is no
connection to Ethernet 1 so the normal state of this LED is turned
Off. If Jumper E1 on the CP3140 switch is connected between
pins 1-2, port 17 on the base network is disconnected from the
switch front panel but is instead routed Ethernet 1 on the ShMM
across the mid-plane. The LED will then follow the same criteria
as Ethernet 0.
|
|
Ethernet 1 Activity
|
Green
|
As with the Ethernet 1
Link Speed LED, the default for this LED is to be turned Off
since there is no connection. If the jumper is made on the switch,
this green LED will then Blink when there is network
activity

Lower Status LED
|
Green
|
This
LED shows Solid Green
to indicate that that the Shelf Management Module is operating as
the Active ShMM.
If
the ShMM is operating in the backup mode, the LED will Blink.
|
|
Upper Status LED
|
Red
|
When this LED
shows solid RED it indicates "Out of Service" implying
that the ShMM is currently not operational. If this occurs
immediately after inserting the ShMM sheck whether the Lower
status LED is lit, it may be necessary to press the reset button
to
|
Note
1: If both ShMM have a Solid Green LED displayed,
sometimes referred to as a 'Racing' condition, both ShMM are
competing for the primary ShMM position. This has been observed
with older firmware, but not since Release 3 of the ShMM firmware.
One may attempt to pull one of the ShMMs to allow the other one to
become Primary.
Note
2: If both ShMM are
displaying Solid Red LEDs, this indicates that both ShMM are
in a failed stated and under this condition you will not be able to
connect to either of the ShMMs in question. Normally, one would
examine the chassis or replace one of the ShMM to verify that we have
actually a faulty ShMM. In this condition, the fan will spin up at
full speed. And if it is not fixed in 15 minutes, the chassis
will power itself down even if all other components are still
functioning normally.

An error or event that
is detected by the system with a fatal impact to the system. In
this case, the system/node can not continue to operate. Check LEDs
and message files on all other boards

An error or event that
is detected by the system and has discernible impact to system
operation. In this case, the system/node can continue to operate
but in a "degraded" fashion (reduced performance or loss
of non-fatal feature reduction). An example could be the loss of
one of two mirrored disks. Check LEDs and message files on all
other boards

* By
Default Port 17 on the Base Network is routed to the Switch Front
Panel.
The User may enable Net-connect for ShMM Netconsole
redundancy by installing jumper E1 on pins 1-2 of each of the Netra
CP3140 Switch Boards. With this jumper installed, port 17 on the Base
Network is routed through to ethernet 1 on the ShMM and the front
panel socket is disabled. Switch Board 7 routes to the Upper ShMM,
and Switch Board 8 routes to the lower ShMM.
In
many cases it will not be possible to gain physical access to view
the status LEDs. In these circumstances the clia
getfruledstate command will provide
additional scope for determining the status of the various
components. To use this feature requires that you can connect
to the ShMM via the network or serial port. If connection to one ShMM
is not possible try the other one.
The
syntax for using this will change slightly depending whether you wish
to collect the information on all the FRUs or one FRU at a time. It
may be necessary to run the clia fru command to identify the
IPMI address to be used with the clia getfruledstate command.
Example
1: To interrogate the LED status for the Upper ShMM
#clia
getfruledstate -v 10
10:
FRU # 0, Led # 0 ("BLUE LED"):
Local Control LED State: LED
OFF
LED's color capabilities:
Colors supported(0x02): BLUE
Default LED Color in Local
Control State(0x01): BLUE
Default LED Color in Override
State(0x01): BLUE
10:
FRU # 0, Led # 4 ("Application Specific LED# 1"):
Local Control LED State: LED
ON, color: GREEN
LED's color capabilities:
Colors supported(0x0C): RED
GREEN
Default LED Color in Local
Control State(0x03): GREEN
Default LED Color in Override
State(0x03): GREEN
In
this condition we observe Blue LED OFF and Green LED ON
indicating a normal operational status, and that this is the Active
ShMM.
Example
2: To interrogate the LED status for the Shelf Alarm Panel
#
clia getfruledstate 20 8
20:
FRU # 8, Led # 1 ("LED 1"):
Local
Control LED State: LED OFF
20:
FRU # 8, Led # 2 ("LED 2"):
Local
Control LED State: LED ON
20:
FRU # 8, Led # 3 ("LED 3"):
Local
Control LED State: LED OFF
This
shows the three Telco Alarm LEDs. In this example, the Major Telco
Alarm LED is ON therefore further investigation of the other
boards in the shelf will be required.
