Powering On Devices
After installing all devices, power on them and check their operating status. It is critical to ensure all devices and hardware have been properly installed before powering on them.
Context
- Devices can be powered on only when representatives from the customer and Huawei are onsite to confirm the operation.
- Use of power sourcing equipment (PSE), power distribution equipment (PDE), and powered devices (PDs) must comply with standards and regulations.
- After the customer's administrative unit has approved the power-on application, the devices can be powered on and operated under the supervision of the customer's technicians and engineers.
- PDs must be connected to the PSE and PDE at the positions specified on the units.
- You must use a measuring instrument to check whether the power supplies meet the following requirements before powering on a device:
- The device and its power supply are not short-circuited, the power cable is firmly connected, the output switch of the PSE is turned off, and the output voltage is within the normal range.
- All power switches of the PDs are turned off.
Procedure
- Connect ground cables.
- Huawei personnel must connect all ground cables for cabinets and storage devices and check that the ground resistance connectors are firmly attached.
- Huawei personnel must also test the ground resistance between the storage cabinets and the equipment room.
- Power on power distribution frames (PDFs) and cabinets.
- Huawei is responsible for turning on miniature circuit breakers (MCBs) and switches of PDFs and cabinets.
- The customer must check the output voltage of the PDFs and cabinets and ensure that it falls within the normal range. The customer must also verify that the PSE has sufficient redundant power supplies to meet the power requirements of all connected cabinets and storage devices.
- Power on devices.
- Huawei is responsible for turning on switches of power distribution units (PDUs) and powering on devices in sequence under the customer's supervision.
The power-on sequence is: storage devices > Fibre Channel switches > core switches > application servers.
Verify that each device is operating properly before powering on the next. For details about how to power on storage devices, see "Powering On Devices" in the installation guide specific to your product model.
- The customer must verify that the input power is stable while Huawei personnel are powering on the cabinets and storage devices.
- Huawei is responsible for turning on switches of power distribution units (PDUs) and powering on devices in sequence under the customer's supervision.
Follow-up Procedure
After powering on devices, you must verify that:
- Fans of the devices are working properly and air is being exhausted from the air vent.
- The device indicators are normal.
For details about the indicator status, see the product description specific to your product model.
- Log in to each device and check its operating status.
