being supplied to the power supply through the power cord. During normal
operation, both the ac and dc power LEDs are lit. For any other combination of
LEDs, see the Problem Determination and Service Guide on the IBM Documentation
CD.
v DC power LED: Each hot-swap power supply has a dc power LED and an ac
power LED. When the dc power LED is lit, it indicates that the power supply is
supplying adequate dc power to the system. During normal operation, both the
ac and dc power LEDs are lit. For any other combination of LEDs, see the
Problem Determination and Service Guide on the IBM Documentation CD.
v System-error LED: When this LED is lit, it indicates that a system error has
occurred. An LED on the light path diagnostics panel is also lit to help isolate
the error. This LED is functionally equivalent to the system-error LED on the
front of the server.
v Power-on LED: When this LED is lit and not flashing, it indicates that the server
is turned on. This LED is functionally equivalent to the Power-on LED on the
front of the server. The states of the power-on LED are as follows:
Off: AC power is not present, or the power supply or the LED itself has
failed.
Flashing rapidly (4 times per second): The server is turned off and is not
ready to be turned on. The power-control button is disabled. This lasts
approximately 1 to 3 minutes.
Flashing slowly (once per second): The server is turned off and is ready to
be turned on. You can press the power-control button to turn on the server.
Lit: The server is turned on.
Fading on and off: The server is in a reduced-power state. To wake the
server, press the power-control button or use the IMM Web interface. See
“Logging on to the Web interface” on page 146 for information about logging
on to the IMM Web interface.
v Locator LED: Use this LED to visually locate the server among other servers.
You can use IBM Systems Director to light this LED remotely. This LED is
functionally equivalent to the locator LED on the front of the server.
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 1280 x 1024 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 USB connectors: Connect a USB device, such as a USB mouse, keyboard, or
other device to any of these connectors.
v Systems-management Ethernet connector: Use this connector to manage the
server, using a dedicated management network. If you use this connector, the
IMM cannot be accessed directly from 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 QPI link LEDs
When these LEDs are lit, they indicate that there is an active link connection to
the MAX5 or another x3690 server.
