IBM SAN Volume Controller 2145-CG8, Руководство по техническому обслуживанию аппаратной части

Страница: 19 / 372

Each device has required safety items installed to protect users and IBM 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-IBM 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 SAN Volume Controller node for unsafe conditions, perform the following steps. If
necessary, see any suitable safety publications.
1. Turn off SAN Volume Controller 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:
a. 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.
b.
Ensure that the power cord is the appropriate type, as specified in the parts listings.
c. 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 SAN Volume Controller 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 SAN Volume Controller to the storage area network (SAN), check the grounding.
External device check
Ensure that you perform an external device check before you install or service the SAN Volume
Controller.
To conduct an external device check, perform the following steps:
1. Verify that all external covers are present and are not damaged.
2. Ensure that all latches and hinges are in the correct operating condition.
3.
If SAN Volume Controller is not installed in a rack cabinet, check for loose or broken feet.
4. Check the power cord for damage.
5.
Check the external signal cable for damage.
6. Check the cover for sharp edges, damage, or alterations that expose the internal parts of the device.
7. Correct any problems that you find.
