Safety
On-the-job safety is important; therefore, observe the following safety precautions
during all maintenance activity. Failure to do so could result in injury.
Remove all conductive jewelry, such as watches and rings, before servicing
powered-on equipment.
Be careful to avoid shocks when working near power connectors and supplies.
Power off the equipment being serviced before removing a field replaceable
unit (FRU) or other component. Remember that dangerous voltages could still
be present in some areas even though power is off.
NOTE: The disconnect device for the PowerVault 130T library is the AC
power receptacle, located at the bottom of the rear panel of the
electronics module.
Ground all test equipment and power tools.
Lift objects properly, as outlined under “Lifting Techniques.”
Enforce good housekeeping practices in the equipment area to help prevent fire
and accidents.
Lifting Techniques
Lifting, regardless of how much or how little, can create serious back stress.
Follow these guidelines to reduce the risk of back injury:
Do not twist your body to pick something up or put it down. Twisting puts
extreme pressure on your back, especially when you lift or carry objects.
Instead of twisting, make the task two separate moves; first lift, and then use
your feet to turn your body.
Plan the lift by examining the object and determining how it will be lifted and
where it will be placed.
Choose the appropriate lifting technique. Examine the weight, size, location,
frequency, and direction of the lift. Plan to avoid awkward postures and
determine if material-handling aids are needed.
