If installing the Linux operating system (one of these):

•SUSE Linux Enterprise Server 11 for the Power 755 Server, or later, with current maintenance updates available from Novell to enable all planned functionality

•SUSE Linux Enterprise Server 10 Service Pack 3 for the Power 755 Server, with current maintenance updates available from Novell to enable all planned functionality

Users should also update their systems with the latest Linux for Power service and productivity tools available from IBM's Web site

If installing VIOS:

• VIOS 2.1.2.11 with Fix Pack 22.1 and Service Pack 1, or later

Java 1.4.2 on POWER7

There are unique considerations when running Java 1.4.2 on POWER7. For best exploitation of the outstanding performance capabilities and most recent improvements of POWER7, IBM recommends upgrading Java-based applications to Java 6 or Java 5 whenever possible.

Limitations

System

•When an HMC is connected to the system, the integrated system ports are rendered nonfunctional. In this case, the customer must install an asynchronous adapter for serial port usage.

•Integrated system ports are not supported under AIX or Linux when the HMC ports are connected to an HMC. Either the HMC ports or the integrated system ports can be used, but not both.

•The integrated system ports are supported for modem and async terminal connections. Any other application using serial ports requires a serial port adapter

to be installed in a PCI slot. The integrated system ports do not support HACMPTM configurations.

Processor cards

•Four processor cards are required.

•All processors must be activated.

–Because four processor cards are required in the 8236-E8C system, a minimum and maximum of 32 processor activations are required: 32 x #2325 must be on the order.

Power supply

• The base machine contains two ac power supplies (#7740).

Redundant fans

• Redundant fans standard
