17 Safety and Enironmental Notices Danger Notice When using this product, obsere the danger, caution, and attention notices that are contained in this guide. The notices are accompanied by symbols that represent the seerity of the safety condition. Most danger or caution notices contain a reference number (Dxxxx or Cxxxx). Use the reference number to check the translation in the IBM Systems Safety Information (G ) publication included in your ship group. The sections that follow define each type of safety notice and gie examples. A danger notice calls attention to a situation that is potentially lethal or extremely hazardous to people. A lightning bolt symbol always accompanies a danger notice to represent a dangerous electrical condition. Caution Notice A caution notice calls attention to a situation that is potentially hazardous to people because of some existing condition. A caution notice can be accompanied by one of seeral symbols: If the symbol is... It means... A hazardous electrical condition with less seerity than electrical danger. A generally hazardous condition not represented by other safety symbols. A hazardous condition due to the use of a laser in the product. Laser symbols are always accompanied by the classification of the laser as defined by the U. S. Department of Health and Human Serices (for example, Class I, Class II, and so forth). A hazardous condition due to mechanical moement in or around the product. A hazardous condition due to the weight of the unit. Weight symbols are accompanied by an approximation of the product s weight kg ( lbs) sc00168 Copyright IBM Corp. 2005, 2008 x

18 If the symbol is... It means... A hazardous condition due to the unit's susceptibility to electrostatic discharge. xi TS3100 Tape Library and TS3200 Tape Library Setup, Operator, and Serice Guide

19 Laser Safety and Compliance Before using the library, reiew the following laser safety information. Class I Laser Product The library may contain a laser assembly that complies with the performance standards set by the U.S. Food and Drug Administration for a Class I laser product. Class I laser products do not emit hazardous laser radiation. The library has the necessary protectie housing and scanning safeguards to ensure that laser radiation is inaccessible during operation or is within Class I limits. External safety agencies hae reiewed the library and hae obtained approals to the latest standards as they apply. Performing the Safety Inspection Procedure Before you serice the unit, perform the following safety inspection procedure: 1. Stop all the actiities between the host and the library s tape dries. 2. Turn off the power to the library by pushing in on the Power button (1) shown in Figure 1-1 on Page 1-1 for 4 seconds. 3. If dries are SCSI attached, disconnect the SCSI cable and check the SCSI bus terminator for damage. 4. Unplug the library s power cord or cords from the electrical outlet and the library power supply. 5. Check the library s power cord for damage, such as a pinched, cut, or frayed cord. 6. If dries are SCSI attached, check the tape drie s SCSI bus (signal) cable for damage. 7. If dries are FC/SAS attached, check the tape drie s FC/SAS cable for damage. 8. Check the coer of the library for sharp edges, damage, or alterations that expose its internal parts. 9. Check the coer of the library for proper fit. It should be in place and secure. 10. Check the product label at the rear of the library to make sure that it matches the oltage at your outlet. Safety and Enironmental Notices xii

20 Rack Safety The following general safety information should be used for all rack mounted deices. DANGER Always lower the leeling pads on the rack cabinet. Always install stabilizer brackets on the rack cabinet. To aoid hazardous conditions due to uneen mechanical loading, always install the heaiest deices in the bottom of the rack cabinet. Always install serers and optional deices starting from the bottom of the rack cabinet. Rack mounted deices are not to be used as a shelf or work space. Do not place any object on top of rack mounted deices. Each rack cabinet might hae more than one power cord. Ensure that all power cords in the rack cabinet are disconnected before sericing any deice in the rack cabinet. Connect all deices installed in a rack cabinet to power deices installed in the same rack cabinet. Do not plug a power cord from a deice installed in one rack cabinet into a power deice installed in a different rack cabinet. An electrical outlet that is not correctly wired could place hazardous oltage on the metal parts of the system or the deices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to preent an electrical shock. xiii TS3100 Tape Library and TS3200 Tape Library Setup, Operator, and Serice Guide
