Using the RS-485 terminator plugs on interconnected

servers

The Remote Supervisor Adapter II comes with two RS-485 terminator plugs. To

ensure successful RS-485 communication on your ASM interconnect network,

you must install a terminator plug in the open connector at each end of the

RS-485 bus. The illustrations in "ASM interconnect network configuration

examples" on page 31 can help you determine where to put the RS-485

terminator plugs on your ASM interconnect network.

Considerations when configuring xSeries 232 and xSeries

342 servers

You can connect xSeries 232 and xSeries 342 servers to an ASM interconnect

network using the integrated system management processor (ISMP) connectors

located on the back of those servers. If the ISMP firmware level is revision 6 or

8, you must update the ISMP firmware. Go to

http://www.ibm.com/pc/support/ to obtain the latest ISMP firmware and

update instructions.

Attention:

1. If your server BIOS code level is earlier than revision 1.02, you must

update your server BIOS code before you update the ISMP firmware. BIOS

update diskettes and update instructions are available from the IBM

Support Web site.

2. Make sure that no servers or devices are connected to the server ISMP

connectors when you update the ISMP firmware if its level is revision 6 or

8. You cannot update the firmware while devices are connected to the ISMP

connectors.

You must connect at least one Remote Supervisor Adapter to the ASM

interconnect network to support the connection of xSeries 232 and xSeries 342

servers using their ISMP connectors. If your Remote Supervisor Adapter

firmware level is earlier than revision 17, you must update the Remote

Supervisor Adapter firmware. Go to http://www.ibm.com/pc/support/ to

obtain the latest Remote Supervisor Adapter II firmware and update

instructions.

Remote Supervisor Adapters, ASM PCI adapters, ASM processors, and ISMPs

that are connected to an ASM interconnect network share resources and

system-management information. This section provides information about how

alerts are forwarded in the ASM interconnect network.
