You turn on power on to the units in the system in this order:
PowerVault 700N storage systems and tape backup device (any order)

Checks all connections to the filer
Starts the setup program
This section uses a system with three units as an example—filer, PowerVault 700N
storage system, and tape backup device. Assume that you have these three units
installed and connected in a rack and are ready to turn them on.
To turn on the PowerVault 700N storage system and tape backup device, refer to the
documentation for those products.
Do not proceed if the PowerVault 700N storage system(s) or the tape backup device
fail to power up. Recheck all connections and the power source, and then retry.
To connect the filer to a power source, perform the following steps:
1. Ensure that the power switch on each power supply is in the Off position.
2. Connect the socket end of the power cord to the recessed power plug on the
power supply.
3. Secure the AC cord with the retaining clip.
