interconnect network. For information about using a Remote Supervisor Adapter for
remote server management, see the documentation that comes with the adapter.
Before cabling the ASM interconnect network, review the following information:
v
The cables in an ASM interconnect network are hot-swappable.
v Make sure that the firmware for the Remote Supervisor Adapter, ASM processor,
and integrated system management processor (ISMP) are at the latest level.
v
The servers in an ASM interconnect network are referred to by their assigned
addresses, not by their positions in the rack.
An ASM interconnect network can have up to 24 RS-485 connections, depending
on the configuration. The connections can include Remote Supervisor Adapters,
ASM processors, ASM PCI adapters, and ISMPs. Use the following information to
determine the number of servers and connections that you can have on your ASM
interconnect network:
v Each Remote Supervisor Adapter, ASM processor, ASM PCI adapter, and ISMP
in a server that is connected to the network uses one connection. For example, if
a server that is connected to the network has a Remote Supervisor Adapter and
an integrated ASM processor, the server uses two connections on the network.
v The network must include at least one server with a Remote Supervisor Adapter
(either installed as an option or preinstalled in the server).
You can connect up to 23 xSeries 335 servers into an ASM interconnect network
using one Remote Supervisor Adapter. However, if you use both xSeries 335 and
xSeries 330 servers in the network, the xSeries 330 servers must be the
lowest-numbered servers in the chain. The following illustration shows an ASM
interconnect network with three servers.

You can add up to 23 more servers to the network by installing a Remote
Supervisor adapter in the 24th server, creating a second ASM bus. The following
