IBM 440 manual Remote Supervisor Adapter connectivity, Remote Supervisor Adapter Connectors

￿In 16-wayconfigurations, the Ethernet port on the Remote Supervisor Adapter in one system is connected to the Ethernet port of the adapter in the other system. This connection is used during system startup and shutdown.

We recommend either of the following connections:

–Connecting the two using a crossover cable, as shown in Figure 3-6 on page 76.

–Connecting the two over an isolated LAN segment using a switch or hub.

Connecting over a LAN segment will enable you to maintain Ethernet connectivity directly to the Remote Supervisor Adapter for out-of-band management.

Tip: We recommend that you assign static IP addresses to the Remote

Supervisor Adapters on both servers.

3.2.2 Remote Supervisor Adapter connectivity

The x440 features an integrated Remote Supervisor Adapter (RSA). For detailed information on functionality and configuration of the RSA refer to section 9.5 “Remote Supervisor Adapter” in the redbook Implementing IBM Director Management Solutions, SG24-6188. This document talks about the Remote Supervisor Adapter as a separate adapter; however the functionality and location of ports is consistent with the integrated version of the RSA in the x440.

The following RSA connections need to be considered when cabling the x440 (see Figure 3-7):

￿External power supply connector. This connector allows the RSA to be connected to its own independent power source. This external power supply is not included with the x440 and will need to be ordered as an option (order a ThinkPad 56W AC Adapter with a suitable power cord for your country/region).
