Caution
It is important to follow the correct Power On sequence. Failure to do so may
result in some features not functioning properly.
3.2.2 Powering Off
If you need to power off the entire system, such as in the cases of switch or RAID system firmware
updates, adding a RAID system or client computer, power off in the reverse order of Powering On. Before
turning off the B08S2-PS Storage System, turn off the host server first. During RAID initiation or disk
drive rebuilding, you can turn off the host server and leave the B08S2-PS powered on.
