Cabling the ac power supply for ac models
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.
supplies to a different power source.
4. Continue with “Powering on the storage subsystem” on page 119 for the initial
startup of the storage subsystem.
