Connecting the Advanced System Management Interface (ASMI)
__ If you plan to access the ASMI using the ASCII terminal, see Accessing the ASMI using an ASCII console for
instructions.
Cabling the expansion units
__ Do you have an expansion unit?
Yes. For instructions on how to set up your expansion unit, click the following link. Do not plug the
v
expansion-unit power cord into the power outlet, as directed in the following link, until later in the checklist.
Expansion units
v No. Proceed to the next section, Connecting the external cables.
Connecting the external cables
__ If you are using any optional adapters (such as token ring or 8-port EIA-232), connect the cables to the
appropriate adapter connectors in the PCI slots of your machine.
Note: If the cable did not come with your server, you will have to supply it.
Attaching devices using the system ports
__ If you want to access the ASMI when the system is in standby, attach an ASCII terminal to a system port on the
back of the server. For views of the back of each server, see References.
__ If you want to access the ASMI remotely when the system is in standby, attach a modem to a system port on the
back of the server. For views of the back of each server, see References.
__ If you are connecting your server to an uninterruptible power supply, refer to the documentation that is
included with your uninterruptible power supply. You might need additional hardware.
Notes:
1. Any other application that uses a system port requires a system port adapter to be installed in a PCI slot.
2. The attachment of high availability cluster multiprocessing IBM (HACMP) cables to the system ports on the back
of the server is not supported.
Connecting the power cords
__ Power cords should be routed through the retention rings or under the retention brackets that are provided to
prevent the power cords from becoming unplugged unexpectedly.
