Description
The blue system status indicator lights up during normal system operation. Both the systems management software and
the identification buttons located on the front and back of the system can cause the blue system status indicator to flash
to identify a particular system.
The amber system status indicator flashes when the system needs attention due to a problem with power supplies, fans,
system temperature, or hard drives.
NOTE:
If the system is connected to AC power and an error has been detected, the amber system status indicator flashes
regardless of whether the system has been powered on.
The link and activity indicators for the two integrated NICs light intermittently when the NICs are in use.
The green
hard-drive activity indicator flashes when the hard drives are in use. See Figure 1-3
hard-drive indicators.
The power-on indicator lights when the system power is on.
The power button controls the DC power supply output to the system.
NOTE:
If you turn off the system using the power button and the system is running an ACPI-compliant operating system,
the system performs a graceful shutdown before the power is turned off. If the system is not running an ACPI-compliant
operating system, the power is turned off immediately after the power button is pressed.
The identification buttons on the front and back panels can be used to locate a particular system within a rack. When one
of these buttons is pushed, the blue system status indicator on the front and back blinks until one of the buttons is
pushed again.
Connects a USB 1.1-compliant device to the system.
Connects a monitor to the system.
