PowerVault 130T Service Manual Safety and ESD Safety The following pages cover three topics that are essential to all service activity: 1. Safety 2. Preventing electrostatic discharge (ESD) damage to equipment 3. Rack-mounted library safety and precautions 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. 4473D ix
