Accusys ExaSAN A12S2-PS - Manual (Page 17)

1.4 Powering On and Off the A12S2-PS
1.4.1 Powering On
Before powering on the A12S2-PS, make sure that all cables and cords are properly installed and connected.
1. Turn power on for the A12S2-PS by switching on the Power button. Wait for the Controller A status (refer to the
figure on A12S2-PS Front Panel LEDs) to turn into a steady blue state. Note that you might hear a few short
beeps generated from the RAID disk system during this process. You may ignore them as they are designed for
Accusys’ internal diagnostic purpose only.
2. Turn on the host server.
1.4.2 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 following sequence.
1. Turn off the host server first. During RAID initiation or disk drive rebuilding, you can turn off the host server and
leave the A12S2-PS powered on.
2. Power off the A12S2-PS RAID System by turning off the power switch.
Caution
It is important to follow the correct Power On sequence. Failure to
do so may result in some features not functioning properly.
