DHCP server on the network the BladeCenter unit is connected to, it takes two minutes before the management module uses the default (static) IP address.

When the DHCP search times out and the management module uses the static IP address, you can change the management module configuration so that it will not attempt to locate a DHCP server (MM Control → Network Interfaces → External Network Interface → DHCP, select Static only).

System LED panel

The following illustration shows the status LEDs on the system LED panels on the front and rear of the BladeCenter unit.

Location Information

Power-on

Over-temperature

System error

Attention: If the power-on LED is off, it does not mean there is no electrical current present in the BladeCenter unit. The LED might be burned out. To remove all electrical current from the BladeCenter unit, you must disconnect all power cords from all power modules.

Note: You can turn off the location LED and the information LED through the Web interface or the IBM Director console.

Power-on:When this green LED is lit, power is present in the BladeCenter unit. When this LED is off, the power subsystem, the ac power, or the LED has failed, or the management module is not present or not functioning.

Location: When this blue LED is lit or flashing, it has been turned on by the system administrator, to aid in visually locating the BladeCenter unit. If a blade server requires attention, the location LED on the blade server usually will also be lit. After the BladeCenter unit has been located, you can have the system administrator turn off the location LED.

Over-temperature:When this amber LED is lit, the temperature in the BladeCenter unit exceeds the temperature limits or a blade server reports an over-temperature condition. The BladeCenter unit might have already taken corrective action, such as increasing the blower speed. This LED turns off automatically when there is no longer an over-temperature condition.

Information: When this amber LED is lit, a noncritical event has occurred that requires attention, such as the wrong I/O module inserted in a bay or power demands that exceed the capacity of power modules currently installed. The event is recorded in the event log. Check the LEDs on the BladeCenter unit and the blade servers to isolate the component (see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM BladeCenter Documentation CD for instructions for viewing the event log and checking the LEDs). After the situation is handled, have the system administrator turn off the information LED.

System-error:When this amber LED is lit, it indicates that a system error has occurred, such as a failed module or a system error in a blade server. An LED on one of the components or on a blade server is also lit to further isolate the error. (For more information, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM BladeCenter Documentation CD.)
