Solution Type Problem Resolution Sure Solution 1008744.1 : Ultra[TM] 450 (U450) activity led blinks on one system and is steady on another...why?
PreviouslyPublishedAs 212006 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".
