Sun Enterprise 450 activity led blinks on one system and is steady on
another.
Why does that occur?Resolution: Top

>From FIN I0406-1

Some confusion has been noted in the field in reference to the front
panel status LEDs on Ultra 450 Workstations and Ultra Enterprise[TM] 450
(E450) Workgroup Servers, that blink on some systems and not on others.

The following is an explanation of the apparent random front panel LED
activity:

The Ultra Enterprise 450 and Ultra 450 NVRAM variable mfg-options sets
the system up as a workstation or server.  The system name displayed in
the banner, energystar, watchdog-enable, and the front panel LEDs are
controlled by this variable.

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

        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

        banner          Ultra 450
        energystar      enabled
        watchdog        disabled
        led-blink       disabled

On newer E450's with a system board part number of 501-5270,
501-5672 or 501-5673 the following is true if OpenBoot[TM] PROM
(OBP) is 3.12.3 or greater.

For the front panel LED to blink the "mfg-options" must
be set to "server" Ex. OK> setenv mfg-options server

For the front panel to remain steady the "mfg-options" must
be set to workstation. Ex. OK> setenv mfg-options workstation.

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