the plug of the main power cable of the redundant ac-power switch. If the test
is successful, test the grounding continuity between a conductive area on the
SAN Volume Controller frame and the ground pin on the plug of the backup
power cable of the redundant ac-power switch. Both tests must be successful.
9. After you have completed testing the grounding continuity, perform one of the
following procedures, depending on the outcome of the test.
v If the test is successful, reconnect any cables that were removed, and power
on any uninterruptible power-supply units and SAN Volume Controller
nodes that were powered off.
v
If the test was not successful, ensure that all cables are securely connected. If
the test still fails, test the individual system components. Before you test the
individual components, remove all cables from the components. If any
component test fails, replace the component. After each component has been
tested and the failing ones have been replaced, repeat the complete system
test by returning to step 1 on page xi.
Test the components in the following order:
a. The SAN Volume Controller node, from the frame to the ground pin of
the input power receptacle
b. The uninterruptible power supply from the ground pin of the input
power receptacle to the ground conductor of the output power receptacle
c. If used, the redundant ac-power switch from the ground pin of the main
input power receptacle to the ground conductor of the output power
receptacle, and from the ground pin of the backup input power receptacle
to the ground conductor of the output power receptacle
d. The SAN Volume Controller node to uninterruptible power-supply
power-cable assembly, between the two ground conductors of the power
cable
e. The uninterruptible power-supply input-power cable, between the two
ground conductors of the power cable
f. If used, the redundant ac-power switch main input-power cable, between
the two ground conductors of the cable
g. If used, the redundant ac-power switch backup input-power cable,
between the two ground conductors of the cable
Inspecting the uninterruptible power supply for unsafe conditions
Ensure that you take the time to inspect the uninterruptible power supply for
unsafe conditions.
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 bulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious
injury.
Use caution when working in a potential safety hazard 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.
