38 en Subsystem Connection and OperationRAID Subsystem
5.4 | Power On | |
| After installing all the components in the subsystem, connecting the host channels to the | |
| host, and connecting the expansion cables to the expansion enclosures, the subsystem is | |
| ready to be powered on. | |
5.4.1 | Power On Checklist | |
| BEFORE powering on the subsystem, please check the following: | |
| • | Memory module: Memory module has been correctly installed on the controller board. |
| • | BBU modules: Ensure that the BBU modules have been installed correctly. |
| • | Hard drives: Hard drives have been correctly installed on the drive trays. |
| • | Drive trays: ALL the drive trays, whether or not they have a hard drive, have been installed |
| • | into the subsystem. |
| Cable connections: The host ports on the subsystem have been correctly connected to | |
| • | host computer(s). |
| Power cables: The power cords have been connected to the PSU modules on the subsys- | |
| • | tem and plugged into main power. |
| Ambient temperature: All the subsystem components have been acclimated to the sur- | |
|
| rounding temperature. |
5.4.2 | Power On Sequence | |
| When powering on the subsystem, please follow the steps below: | |
| 1. | Power on any expansion enclosures if applied |
|
| If you connect any expansion enclosures to the subsystem, power on those expansion |
|
| enclosures before powering on the subsystem. |
| 2. | Power on the subsystem |
|
| The subsystem should be powered on before the host computers. The power on proce- |
|
| dure for the subsystem is described in Section 5.4.3 Power On Procedure. |
| 3. | Host computers |
|
| Host computers should be the last devices that are turned on. Please refer to the docu- |
|
| mentation that came with your host computers to see its own power on procedure. |
5.4.3 | Power On Procedure | |
| 1. | Plug in all power cords to the power connectors located at the rear of the subsystem. Use |
|
| the power cables that came with the subsystem to connect the subsystem to the power |
|
| outlet, separate power sources, or UPS devices. |
| 2. | Turn on the power supply switches for both power supply units. |
| 3. | The subsystem is now turned on and the |
| 4. | The “Power” LED on the front LCD panel will turn blue. |
CAUTION!
Although the PSUs are redundant and a single PSU can provide sufficient power to the sys- tem, it is advisable to turn both the power switches on. If only one PSU is operating and fails, the whole system will shut down.
