1. Plug a power cord into each power supply with fan module.
2. Plug the other end of the power cords into the external power source for the cabinet.
Note:
To guarantee redundancy, power cords must be connected to two separate and independent
power sources.
3. Apply power to the external power source.
4. Place the power supply on/off switches to the
"
I
"
on position.
5. Turn on the cabinet circuit breakers, if applicable.
6. After the disk shelf powers on, which could take several minutes, ensure that the system
power indicator on the front of the disk shelf is lit a steady green, and that each power supply
with fan module status indicator on the rear is lit a steady green. If not, power off the disk
shelf as described in the next section and reseat the faulted module. If the module status
indicator is not a steady green after module reinsertion, contact Oracle Customer Service.
7. Perform the software setup tasks as described in the storage controller installation guide.
Powering Off the Disk Shelf
Most disk shelf components are hot-swappable; you do not need to remove power when
replacing them. Do not remove a component if you do not have an immediate replacement. The
disk shelf must not be operated without all components in place.
Powering off or removing all SAS chains from a disk shelf will cause the controller(s) to panic to
prevent data loss, unless the shelf is part of an NSPF (no single point of failure) data pool. To
avoid this, shut down the controller(s) before decommissioning the shelf. For details on NSPF
profiles, see Profile Configuration.
