7.
Tighten the fastener around the plug.
8. Repeat the steps for each additional power cord.
9.
Plug the power cords into a properly grounded electrical outlet. To provide
power failure redundancy, plug the power cords for the individual power
supply units for each enclosure into separate power distribution circuits, if
possible.
File modules:
Perform the following steps when you attach the power cord to each power supply
unit:
1.
Connect two power cords from a file module rack power supply. Plugging
them into separate Power Distribution Units (PDUs) is recommended for
redundancy. Route the power cords through the Cable Management Arms.
2. Repeat the previous step for the other file module.
3. Secure any excess cable length using the cable retention features of the rack.
Step 13. Powering the system on and off
Follow the procedures for powering on the expansion enclosure and file modules,
and in the order specified. Here are the general procedures to be followed:
1.
Power on the expansion enclosure.
2. Power on the control enclosure.
3.
Power on both file modules.
4. Visually check for error indicators (such as bad disk drive modules, bad power
supplies). Resolve any obvious problems before continuing.
