Internal I/O Subsystem; Slot Configuration; System Ports - IBM Power 710 Technical Overview And Introduction

2.7 Internal I/O subsystem

The internal I/O subsystem resides on the system planar, which supports PCIe slots. PCIe
slots on the Power 710 and Power 730 are not hot pluggable. PCIe and PCI-X slots on the I/O
drawers are hot-pluggable.
All PCIe slots support Enhanced Error Handling (EEH). PCI EEH-enabled adapters respond
to a special data packet generated from the affected PCIe slot hardware by calling system
firmware, which will examine the affected bus, allow the device driver to reset it, and continue
without a system reboot. For Linux, EEH support extends to the majority of frequently used
devices, although certain third-party PCI devices might not provide native EEH support.

2.7.1 Slot configuration

Table 2-8 displays the PCIe Gen2 slot configuration of Power 710 and Power 730.

Remember: Slot 6 is shared with GX++ adapter slot 2. If a PCIe adapter is plugged into
slot 6, then a GX++ adapter

2.7.2 System ports

The system planar has two serial ports that are called system ports. When an HMC is
connected to the server, the integrated system ports of the server are rendered
non-functional. In this case, you must install an asynchronous adapter, which is described in
Table 2-17 on page 50, 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 asynchronous 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 IBM
PowerHA™ configurations.
Configuration of the two integrated system ports, including basic port settings (baud rate,
and so on), modem selection, call-home and call-in policy, can be performed with the
Advanced Systems Management Interface (ASMI).
