8-4 Troubleshooting

POWER/SLEEP Lamp

The green POWER/SLEEP lamp lights to indicate normal operation while the server is powered.
When the server is off-powered, the POWER/SLEEP lamp stays unlit.
The POWER/SLEEP lamp indicates that the server is running in the power-saving mode (sleep
mode). If the OS supports the power-saving mode such as Windows 2000, pressing the
POWER/SLEEP switch blinks the POWER/SLEEP lamp in green and places the server in the
power-saving mode. Press the POWER/SLEEP switch to turn out the POWER/SLEEP lamp and
place the server back in the normal mode.
The power-saving mode is only available when the OS supports the power-saving feature. Some
OS's allow you to set the server to automatically turn in the power-saving mode when no access is
made to the server for a certain period of time or to select the power-saving mode with a command.

DISK ACCESS Lamp

The DISK ACCESS lamp indicates the state of hard disks in the hard disk drive.
This lamp lights in green every time any of such hard disks is accessed.
IMPORTANT:
when optional board (e.g., disk mirroring controller or disk array
controller) is installed, connect the LED cable provided with the server
to the LED connector on the mother board and the optional board.

Access Lamps

The access lamps for the floppy disk drive and the CD-ROM drive light when access is made to a
media in the drive.

LINK/ACT Lamp

The link/ACT lamp indicates the state of each network port normally equipped with the server. If
the power is supplied to the server and the hub and they are correctly connected with each other, the
lamp is lit green (LINK state). If information is transmitted through a network port, the lamp
blinks green (ACT state).
If the lamp is not lit in the LINK state, check the network cable and the cable connection. If the
lamp is not lit still after the checking, the network (LAN) controller may be defected. Contact
your service representative.
