Slot Configuration; System Ports - IBM Power 720 Overview

An optional PCIe Adapter Riser Card (FC 5685) adds four short, 8x PCIe Gen2 low-profile
slots and is installed in a GX++ slot 1. All PCIe slots are EEH, but they are not hot-pluggable.

2.6.1 Slot configuration

Table 2-9 describes the slot configuration of the Power 720 and Power 740.

Remember: Full-height PCIe adapters and low-profile PCIe adapters are not
interchangeable. Even if the card was designed with low-profile dimensions, the tailstock at
the end of the adapter is specific to either low-profile or full-height PCIe slots.

2.6.2 System ports

The system planar has two serial ports that are called
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 2-20 on page 74, 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).
