Inspecting The San Volume Controller For Unsafe Conditions - IBM 2145UPS-1U Hardware Installation Manual

The notices throughout the SAN Volume Controller documentation and in the IBM
Systems Safety Notices document follow specific guidelines for their content.
The following notices are used throughout this library to convey specific meanings:
Note: These notices provide important tips, guidance, or advice.
Attention: These notices indicate possible damage to programs, devices, or data.
An attention notice appears before the instruction or the situation in which damage
might occur.
CAUTION:
These notices indicate situations that can be potentially hazardous to you. A
caution notice precedes the description of a potentially hazardous procedural
step or situation.
DANGER
These notices indicate situations that can be potentially lethal or extremely
hazardous to you. A danger notice precedes the description of a potentially
lethal or extremely hazardous procedural step or situation.
The caution and danger notices that appear in this document are also in the
multilingual IBM Systems Safety Notices document. Use the reference numbers in
parentheses; for example (1), at the end of each notice to find the matching
translated notice.

Inspecting the SAN Volume Controller for unsafe conditions

Use caution when 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 start the safety inspection, make sure the power is off, and the power
cord is disconnected.
Each machine 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 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.
