Inspecting the SAN Volume Controller system for unsafe
conditions
Use caution when you are 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 begin
Before you start the safety inspection, make sure that the power is off, and that the
power cord is disconnected.
About this task
Each device has the required safety items that are installed to protect users and
IBM service personnel from injury. Only those items are addressed.
Important:
Good judgment must also be used to identify potential safety hazards
due to the attachment of non-IBM features or options that are not covered by this
inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard might 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, use the
following steps. If necessary, see any suitable safety publications.
Procedure
1. Turn off the SAN Volume Controller system and disconnect the power cord.
2. Check the frame for damage (loose, broken, or sharp edges).
3. Check the power cables by 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.
