1	CSS indicator (yellow) Lights up yellow when a prefailure event was detected which requires Customer Support to become active (by way of precaution). Flashes yellow when an error was detected which requires Customer Support to become active. Does not light up when the Application Unit is OK. If the event is still acute after the Application Unit has been switched on/off, the indicator is activated after the restart. The indicator also lights up in standby mode. If the indicator flashes yellow, call Customer Support.
2	Global error indicator (yellow) Lights up yellow when a prefailure event was detected which requires Customer Support to become active (by way of precaution). Flashes yellow when an error was detected which requires Customer Support to become active. Does not light up when no critical event has occurred. If the event is still acute after a power failure, the indicator is activated after the restart. The indicator also lights up in standby mode. If the indicator flashes yellow, call Customer Support.
3	ID indicator (blue) Lights up blue when the Application Unit has been selected by pressing the ID button. Press the button again to deactivate it. The ID indicator can also be activated via the ServerView Operations Manager and the iRMC Web GUI, and the status can be reported to the ServerView Operations Manager and the iRMC.
