Installing the storage subsystem configuration
Using the information gathered in the previous sections, install the host systems
and host adapters.
Notes:
1. See the documentation provided with your host adapters for installation
requirements and procedures.
2. Use the correct host adapter driver. For the latest supported host adapters and
drivers, go to the following Web site:
www.ibm.com/servers/storage/support/disk/
Attach
fiber-optic interface cables to each host adapter. You will connect the other
end of the cables to the controller later in the installation process. For more
information about handling fiber-optic cables, see “Handling fiber-optic cables” on
page 48.
Connecting the power cables
This section describes the procedure for connecting power cables to the storage
subsystem.
The DS4800 uses two standard power cords. You can connect the power cords to a
primary power unit inside the rack cabinet, such as a properly grounded ac
distribution unit, or to an external source, such as a properly grounded electrical
outlet.
The DS4800 does not ship with the power cords used to connect the DS4800 to the
electrical outlets outside the rack cabinet. Refer to Appendix D, “Power cords,” on
page 193 for the list of IBM-approved power cords for your region. The DS4800
does ship with two line jumper cords for connecting the DS4800 RAID controller
units to IBM-approved rack PDUs.
Use the following procedure to connect the power cables to the storage subsystem.
Before you connect power cords, turn off all power switches on all modules in the
