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:
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 47.
Cabling the ac power supply
Complete the following steps to connect the ac power supply cable:
1. Using the supplied strap, tie the power supply cord to the rail to provide strain
relief for the power cord.
2. Connect the power cable to the power supply.
3. Plug the supplied power cable into a properly grounded electrical outlet. For
maximum protection against power loss, connect each of the two power
supplies to a different power source.
4. Continue with “Powering on the storage subsystem” on page 95 for the initial
startup of the storage subsystem.
