Perform the following steps to inspect each SAN Volume Controller node for
unsafe conditions. If necessary, see any suitable safety publications.
1. Turn off the 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
machine. Use good judgment about the safety of any such changes.
5. Check inside the 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 the SAN Volume Controller to the SAN, check the
grounding.
External machine check
Ensure that you perform an external machine check before you install the SAN
Volume Controller.
Perform the following steps to conduct an external machine check:
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 the 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 machine checks
Ensure that you perform an internal machine check before you install the SAN
Volume Controller.
Perform the following steps to conduct the internal machine check:
1. Check for any non-IBM changes that might have been made to the machine. 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.
