Sun E450 Server LED light

[americancurly]

We have 4 Sun E450 server that has the front panel LED green Light blinking (which is normal) except for one server. This one server has the green LED light on but it is not blinking. Does anyone know what is happening here?

The Ultra Enterpise 450 & Ultra 450 NVRAM variable mfg-options sets the sysem up as a workstation or server.
Set the mfg-options NVRAM variable to the correct system type relative to the desired led-blink status.

1. The front panel status LEDs will blink if the mfg-options NVRAM variable is set to 49.

Workgroup Server setup:
ok> setenv mfg-options 49
ok> banner
Ultra enterprise 450
energystar disabled
watchdog enabled
led-blink enabled
2. The front panel status LEDs will not blink if the mfg-options NVRAM variable is set to 0.
workstation setup
ok> setenv mfg-options 0
ok> banner
ultra 450
energystar enabled
watchfog disabled
led-blink disabled

On newer E450's with a system board part number 0f 501-5270, 501-5672, 501-5673 the following is true if OBP is 3.12.3 or greater.

For the front panel LED to blink the "mfg-options" must be set to "SERVER": example ok> setenv mfg-options server

For the front panel to remain steady the "mfg-options" must be set to workstation.
EXAMPLE: setenv mfg-options workstation

Failure to do so will result in the message "WARNING
mfg-options environment variable invalid"

Remember after setting the new variable you must issue the reset command to store into MVRAM.

Hope this help.

If I changed the eeprom mfg-options=server while the system is operating, and then just do a reboot of the system, (init 6), will this change take place? Or do I have to reboot the system down to a single user mode, change the parameters, and then do the reset.
