CD-eject button CD-ROM drive activity LED Diskette-eject button Hard disk drive activity LEDs Power LED Diskette drive activity LED Hard disk drive status LEDs USB 1 connector USB 2 connector Operator information panel Power control button Reset button CD-ROM drive activity LED: When this LED is lit, it indicates that the CD-ROM drive is in use. CD-eject button: Press this button to release a CD from the CD-ROM drive. Diskette-eject button: Press this button to release a diskette from the diskette drive. Hard disk drive activity LEDs: When these LEDs are flashing, it indicates that the associated SCSI hard disk drive is in use. Power LED: When this LED is lit, it indicates that ac and dc power are present in the server. When this LED is flashing, it indicates that the server is in Standby mode. When this LED is off, ac power is not present, or the power supply or the LED itself has failed. A power LED is also on the rear of the server. Note: If this LED is off, it does not mean that there is no electrical power in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cord from the electrical outlet. Power-control button: Press this button to turn the server on and off manually.
