Indicator LEDs are provided throughout the chassis to help you identify the operational states of various components. Locator and Power buttons are also provided on the chassis that enable you to initiate a specific action. Indicators may exhibit one of five states: Off, Steady On, Slow Blink (on/off cycle at 1 Hz), Fast Blink (on/off cycle at 4 Hz), and Standby Blink (0.1 second on, 2.9 seconds off). Note that not all indicators use all states.
Indicators and buttons are located on these components:
Front and Rear Indicator Modules (FIM/RIM; chassis summary indicators on the front and rear of the chassis)
Power supply modules
Server Modules (blades)
PCI Express ExpressModules (EMs; Sun Blade 8000 Chassis only)
Network Express Modules (NEMs)
Chassis Monitoring Modules (CMMs)
Front fan modules (Sun Blade 8000 Chassis only)
Rear fan modules
The buttons and indicators for each component are discussed in more detail in related topics.

This LED provides these indications:
You can illuminate the Locator indicator either by executing a software command on the CMM, or by momentarily pressing the associated Locator button. |
Locator button (chassis and blade) |
This button provides these functions:
|
|
Service Action Required indicator (chassis, blade, FRU/CRU) |
Amber |
This LED provides these indications:
|
OK indicator (chassis, blade, FRU/CRU) |
Green |
This LED provides these indications:
|
Ready-to-Remove indicator (blade, FRU/CRU) |
Blue |
This LED provides these indications:
|
Power button (chassis) |
Located on the FIM and RIM, this button powers on the chassis that is in the standby state, as indicated by the OK indicator being in the Standby Blink state. The chassis powers on by default when AC power is applied. The only time you will need to press the Power button is if the Administrator has specifically disabled the automatic power-on feature, or if the chassis has been powered off. Therefore, it is unlikely that you will find the OK LED in the Standby Blink state. The chassis cannot be turned off by pressing the Power button. Only an authorized Administrator, logged in to the active CMM, can turn off the chassis by issuing a CMM software command. |

Power button (blade) |
Located on the front of the blade, this button provides these functions:
|
|
Attention button (NEM) (EM; Sun Blade 8000 Chassis only) |
Located on the Network Express Module and ExpressModule (Sun Blade 8000 Chassis only), this button enables you to activate (if inserting) or prepare to remove (if removing) a NEM or EM during a hot-plug operation. |

Green |
Located on the power supply module, this LED provides these indications:
|
AC-OK (power supply module) |
Green |
Located on the power supply module, this LED provides these indications:
|
