Powering On Devices
After all devices are installed, power on them and check that they are working correctly.
Prerequisite
Before powering on a storage system, ensure that:
- All components have been properly installed and cabled.
- The switches on all the cabinet PDUs or PDBs are set to OFF.
Context
- Before powering on a 2 U controller enclosure, ensure that its slots 0 to 3 (where coffer disks reside) are fully populated with disks.
- Before powering on a storage system, ensure that all expansion cables have been properly connected. If expansion cable connections are adjusted after a storage system is powered on, the storage system may malfunction.
- During the power-on, do not remove or insert optical fibers, network cables, coffer disks, or interface modules to avoid system data loss.
Correct power-on sequence: Turn on the external power switches corresponding to all the devices. > Press the Power button on any controller. > Power on switches (if any switch is deployed but not powered on).
Precautions
- During the power-on process, do not remove any module or any connected cable.
- After the device is powered on, do not change the connection mode of any cable except the maintenance cable.
When powering on a storage system, do not wear an ESD wrist strap to avoid electric shock.
Procedure
- (Optional) If an AC PDB is configured, check the labels on power cables and match the power cables with power switches in the PDB.
For example, if the label on the AC power cable connected to a controller enclosure says PowerBox Output B_8, it indicates that the power cable of the controller enclosure corresponds to power switch SW8 on module Output B. You can turn on that power switch to power on the controller enclosure.
Figure 8-1 shows an AC PDB.
- (Optional) If an AC PDB is configured, turn on the power switches corresponding to all the devices in sequence.
- Press the power button on the controller enclosure, as shown in Figure 8-2.
- To power on the storage system, press the power button. If the power indicator of the controller enclosure is blinking green, the storage system is being powered on. Do not hold down the power button for more than five seconds; otherwise, the storage system will be powered off.
- The power-on of the storage system takes 15 to 30 minutes.
- After the controller enclosure is powered on, other disk enclosures connected will be automatically powered on.
- After system power-on, the disk initialization process automatically starts. The time required for the process is dependent on the quantity of the disks to be initialized.
Follow-up Procedure
The following figures and indicator descriptions are only used to help you determine whether a storage system is successfully powered on. For details about indicators, see the Hardware Description of the storage system.
Figure 8-3, Figure 8-4 and Figure 8-5 show the indicator status displayed when a storage system is successfully powered on.

Check whether the following requirements are met. If yes, the storage system is successfully powered on and is running properly.
- The Power indicators on controllers, controller enclosures, and disk enclosures are steady green.
- The Alarm indicators on controllers, controller enclosures, and disk enclosures are off.
- The Running indicators on coffer disks are steady green, and the Alarm/Location indicators are off.
- Disks with coffer disk labels are coffer disks.
- Before services are configured, the Running indicators on the first three coffer disks are blinking green, and the Alarm/Location indicators are off.
If any Alarm indicator is on, the device is faulty and you need to troubleshoot the fault. For details about how to troubleshoot faults, see OceanStor 2800 V3 V300R006 Troubleshooting. If a power indicator is not steady green, contact Huawei technical support engineers.
