v Remind button: This button places the system-error LED on the front panel into
Remind mode. In Remind mode, the system-error LED flashes once every 2
seconds until the problem is corrected, the server is restarted, or a new problem
occurs.
By placing the system-error LED indicator in Remind mode, you acknowledge
that you are aware of the last failure but will not take immediate action to
correct the problem. The remind function is controlled by the IMM.
v NMI button: Press this button to force a nonmaskable interrupt to the
microprocessor, if directed to do so by IBM service and support.
v Reset button: Press this button to reset the server and run the power-on self-test
(POST). You might have to use a pen or the end of a straightened paper clip to
press the button. The reset button is in the lower-right corner of the light path
diagnostics panel.
For more information about light path diagnostics, see the Problem Determination
and Service Guide on the IBM Documentation CD.
Rear view
The following illustration shows the connectors on the rear of the server.
Ethernet connectors: Use either of these connectors to connect the server to a
network. When you use the Ethernet 1 connector, the network can be shared with
the IMM through a single network cable.
Power-cord connector: Connect the power cord to this connector.
USB connectors: Connect a USB device, such as USB mouse, keyboard, or other
USB device, to any of these connectors.
Serial connector: Connect a 9-pin serial device to this connector. The serial port is
shared with the integrated management module (IMM). The IMM can take control
of the shared serial port to perform text console redirection and to redirect serial
traffic, using Serial over LAN (SOL).
Video connector: Connect a monitor to this connector. The video connectors on the
front and rear of the server can be used simultaneously.
Note: The maximum video resolution is 1600 x 1200 at 75 Hz.
