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 HACMP
TM
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
