  • Page 32: Maintenance

    1.1.2 Safety Procedures and Practices Caution – Do not move or attempt to move the Sun StorEdge A7000 cabinet with the high-density storage array (HDSA) drawer extended or open in any way. The cabinet could become unbalanced and topple if you try to move it incorrectly. Make sure the cabinet is properly level at all times.
  • Page 33 Turn off the energy-isolating device or power disconnect that controls the equipment on which you will be working. (This may be at the customer power distribution panel, the system main power disconnects, or the frame level disconnects. If power needs to be turned off at the customer panel, have the customer turn off the appropriate switch or circuit breaker.) Do not rely on logic controls to power off equipment.

  • Page 34: Electrostatic Discharge Protection

    Repeated tests have shown that, although containers prevent static charge buildup on their contents, they do not shield their contents from damage caused by external static discharge. Sun StorEdge A7000 Service Manual • August 1999...

  • Page 35: Electromagnetic Interference

    Observe these guidelines when packaging and shipping printed circuit boards (PCBs): Always use a grounded wrist strap when handling PCBs. When packaging individual PCBs for local or short distance shipments, put the PCBs into conductive grid bags first, and into protective bags. When packaging individual PCBs for customer or long distance shipments, put the PCBs into conductive grid bags first, then into protective bags, and into a padded shipping container.
