Status Indicators

Your server includes many LED status indicators providing you with detailed
status of server operation. This section provides detailed descriptions of all
server status indicators.

ACT Lamp (

)
The ACT lamp is green while the server is connected to the LAN. The lamp
flashes while the server is accessed via the LAN (during transmission/reception
of packets). The number "1" on the icon indicates LAN port 1, and the number
"2" indicates LAN port 2. The location of this indicator is shown in
Figure 2-35, C.

POWER Lamp (

The green POWER lamp lights to indicate normal operation while the server is
powered. When the server is powered off, the POWER lamp is unlit.
The POWER 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, running a command places the server in a power-saving mode and causes
the power lamp to blink. Press the POWER switch to bring the server out of
power-save 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 enter 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. The location of this
indicator is shown in Figure 2-35, D.

STATUS Lamp (

The STATUS lamp is green while the server is operating normally. Your server
includes this important status lamp on both the front and the rear panels. The
location of this indicator on the front panel is shown in Figure 2-35, E. The
location of this indicator on the rear panel is shown in Figure 2-37, M. If the
STATUS lamp turns amber and/or flashes, it indicates that the server is in an
abnormal state.
The Table 2-1 details the STATUS lamp descriptions and the procedures you
should follow should the status lamp indicate an abnormal state.
Note:
you can determine the cause of a failure by referring to the error log.
