xSeries 206 Type 8482: Installation Guide
On some server models, each hot-swap hard disk drive has a amber status
LED. If the amber status LED for a drive is lit continuously, that individual
drive is faulty. The interpretation of a flashing amber status LED depends
on the SCSI controller connected to the hot-swap drive, as follows:
When the drive is connected to an optional ServeRAID controller, a slowly
flashing (one flash per second) amber status LED indicates that the drive is
being rebuilt. When the LED is flashing rapidly (three flashes per second), it
indicates that the controller is identifying the drive.
When this LED is lit and not flashing, it indicates that the server is turned
on. When this LED is flashing, it indicates that the server is off and still
connected to an ac power source (standby mode).
Press this button to turn the server on and off manually.
When this LED is lit, it indicates that a system error has occurred. A LED on
the system board might also be lit to help isolate the error. See Chapter 6,
"Solving problems," on page 57 for additional information. Detailed
troubleshooting information is in the Hardware Maintenance Manual and
Troubleshooting Guide on the IBM xSeries Documentation CD.
Connect a USB device to these connectors.
This LED is on the Ethernet connector on the back of the server. When this
LED is lit, it indicates that there is an active connection on the Ethernet
port.
This LED is on the Ethernet connector. When this LED is lit, it indicates that
