  • Page 110 P o w e r s y s t e m Signal Function AC good Digital output indicates when true that the AC input voltage is suitable and that the PSU is currently powered by the AC input only. Reference for the control interface. Power On input In Standby (with AC input present), connecting this input to 0V until the PSU asserts DC Good, will power up the PSU.
  • Page 111 P o w e r s y s t e m This signal is used by the System Management Unit in determining whether the AC supply voltage is sufficient to power the system configuration and in reporting AC supply problems to the user. The signal indicates 0V AC input when the unit is in Power Off mode.

    D i a g n o s t i c c o d e s DIAGNOSTIC CODES REFERENCE This lists the diagnostic codes that your server can produce. Some of these codes indicate errors or malfunctions; others are simply way-markers that indicate normal progress.
  • Page 114 D i a g n o s t i c c o d e s ♦ Brownout mode (A.nnn) This mode indicates a temporary reduction or even absence of the AC electric power. If full power is not restored after approximately five seconds, Brownout mode will change to Battery mode.
  • Page 115 D i a g n o s t i c c o d e s 0F10-0F4F These codes indicate various other errors and could appear on the LCD at any point. The following list defines the codes and indicates what action you should take if these errors occur.
