Inspecting the Lenovo Storage V7000system for unsafe conditions

Use caution when working in any potential safety hazardous situation that is not covered in the safety checks. If unsafe conditions are present, determine how serious the hazards are and whether you can continue before you correct the problem.

Before you start the safety inspection, make sure that the power is off, and that the power cord is disconnected.

Each device has required safety items installed to protect users and Lenovo service personnel from injury. This guide addresses only those items.

Important: Good judgment must also be used to identify potential safety hazards due to the attachment of non-Lenovo features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. For example, consider the following conditions and their potential safety hazards:

Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
A damaged CRT face or a bulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious injury.

To inspect each Lenovo Storage V7000 node for unsafe conditions, perform the following steps. If necessary, see any suitable safety publications.

  1. Turn off Lenovo Storage V7000 and disconnect the power cord.
  2. Check the frame for damage (loose, broken, or sharp edges).
  3. Check the power cables using the following steps:
    1. Ensure that the third-wire ground connector is in good condition. Use a meter to check that the third-wire ground continuity is 0.1 ohm or less between the external ground pin and the frame ground.
    2. Ensure that the power cord is the appropriate type, as specified in the parts listings.
    3. Ensure that the insulation is not worn or damaged.
  4. Check for any obvious nonstandard changes, both inside and outside the unit. Use good judgment about the safety of any such changes.
  5. Check inside Lenovo Storage V7000 for any obvious unsafe conditions, such as metal particles, contamination, water or other fluids, or marks of overheating, fire, or smoke damage.
  6. Check for worn, damaged, or pinched cables.
  7. Ensure that the voltage that is specified on the product-information label matches the specified voltage of the electrical power outlet. If necessary, verify the voltage.
  8. Inspect the power-supply assemblies and check that the fasteners (screws or rivets) in the cover of the power-supply unit have not been removed or disturbed.
  9. Before connecting Lenovo Storage V7000 to the storage area network (SAN), check the grounding of the network switch.
