Fading on and off: The server is in a reduced-power state. To wake the
server, press the power-control button or use the IMM2 web interface. See
“Logging on to the web interface” on page 353 for information on logging on
to the IMM2 web interface.
v
System-locator LED: Use this blue LED to visually locate the server among
other servers. You can use IBM Systems Director to light this LED remotely. This
LED is controlled by the IMM2. When you press the System-locator button, the
LED will blink and it will continue to blink until you press it again to turn it off. The
locator button is pressed to visually locate the server among the others servers.
v Hard drive activity LED: When this green LED is lit, it indicates that one of the
hard disk drives is in use.
v
System-error LED: When this yellow LED is lit, it indicates that a system error
has occurred. This LED is controlled by the IMM2.
v Serial connector: Connect a 9-pin serial device to this connector. The serial port
is shared with the integrated management module II (IMM2). The IMM2 can take
control of the shared serial port to perform text console redirection and to redirect
serial traffic, using Serial over LAN (SOL).
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
Systems-management Ethernet connector: Use this connector to connect the
server to a network for full systems-management information control. This
connector is used only by the integrated baseboard management controller
(iBMC). 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
Ethernet connectors: Use either of these connectors to connect the server to a
network. When you enable shared Ethernet for iBMC in the Setup utility, you can
access the iBMC using either the Ethernet 1 or the system-management Ethernet
connector.
v Ethernet link activity/status LED: When any of these LEDs is lit, they indicate
that the server is transmitting to or receiving signals from the Ethernet LAN that
is connected to the Ethernet port that corresponds to that LED.
v
Ethernet connection speed LED: This LED is on each Ethernet connector. The
status of this LED indicates the connection speed, in megabits-per-second
(Mbps), between the server and the network as follows:
– LED off: 10 Mbps connection
– LED lit yellow: 100 Mbps connection
– LED lit green: 1000 Mbps connection
v USB connectors: Connect a USB device, such as a USB mouse or keyboard to
any of these connectors.
