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

Resolution

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".
