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.
Internal device checks
Ensure that you perform an internal device check before you install or service SAN Volume Controller.
To conduct the internal device check, perform the following steps:
1. Check for any non-IBM changes that might have been made to the device. If any are present, obtain
the "Non-IBM Alteration Attachment Survey," form number R009, from the IBM branch office.
Complete the form and return it to the branch office.
2. Check the condition of the inside of the device for any metal or other contaminants, or any
indications of water, other fluid, fire, or smoke damage.
3. Check for any obvious mechanical problems, such as loose components.
4. Check any exposed cables and connectors for wear, cracks, or pinching.
Checking the grounding of SAN Volume Controller, the uninterruptible
power supply, and the redundant ac-power switch
Ensure that you understand how to check the grounding of a SAN Volume Controller, the uninterruptible
power supply, and the optional redundant ac-power switch feature.
To test the grounding of a SAN Volume Controller node, perform the following steps. Follow the steps
for the SAN Volume Controller configuration that you are using. Before you start, confirm that you know
