IBM eserver xSeries 330 - Manual (Page 29)

Chapter 2. Installing Options 17
Working with cables
Your server has two different cabling options, the Advanced System Management bus
(ASM) and the cable chain technology (C2T). The following sections discuss each of
these options. While reading about these options, keep in mind that they are
independent of each other.
Note: Refer to the following illustration to locate the connectors on the back of your
server.
The ASM ports on the back of the server will be referred to in this book as
RS-485 (A) and RS-485 (B).
Note: The illustrations in this document might differ slightly from your hardware.
Cabling the RS-485 ports
You can use the RS-485 connectors to create an Advanced System Management bus
between several xSeries 330 servers.
Before you begin, review the following:
Important: The Advanced System Management bus is designed to support up to 12
units or servers. However, when using the Advanced System Management PCI
adapter, the bus uses the PCI adapter as another unit. In this case, you can connect a
maximum of 11 units or servers together.
• You can hot swap the cables in the Advanced System Management bus.
• You can connect up to 12 units together, if you are using serial (management)
port A as your Advanced System Management port.
• When connecting an xSeries 330 server to another server type, you must install
an Advanced System Management adapter in PCI slot 1 or use the serial port as
your Advanced System Management port.
• Use standard cables with RJ-14 connectors.
Note: For more information about the Advanced System Management PCI adapter,
refer to the documentation that came with the adapter.
