Rear View - IBM System x3750 M4 Type 8722 Installation And Service Manual

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.
v Boot code display: This display provides boot error codes that indicates the
point at which the system stopped during the boot block and POST. A boot code
is a byte value that is produced by UEFI. In addition to UEFI codes, this display
provide error codes in the event of a microprocessor error or a power fault.
Along with the IMM event log, the error codes can provide suggested
components to be replaced.
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.

v Systems-management Ethernet connector: Use this connector to manage the
server, by using a dedicated management network. If you use this connector, the
IMM cannot be accessed directly from the production network. A dedicated
management network provides additional security by physically separating the
management network traffic from the production network. You can use the
Setup utility to configure the server to use a dedicated systems-management
network or a shared network.
v 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.
v 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 redirect serial traffic, using Serial over LAN
(SOL).
v 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.
