and limit cable length. If there are any SE devices on the same SCSIbus, the entire SCSI bus will negotiate down to SE speed and severelydegrade performance.v For a Fibre Channel library, connect the host interface cable to the host or toa switch.v For a SAS library, connect the drive using a host interface cable to the hostHBA. You can connect to either ports if you have a dual port configuration.Unused SAS connectors do not need termination.4. Plug the network ethernet cable (5 in “Connecting the Host Interface Cable”on page 4-12) into the ethernet port on the back panel of the library. If theethernet connection is directly attached to a server or laptop, a crossoverethernet cable may be required.Note: It is the customer’s responsibility to supply the crossover ethernet cableif one is required.Connecting a Power CordAttention: This product can ONLY be used with an approved power cord foryour specific geographic region. Use of an unapproved power cord may result in:v not meeting individual country specific safety requirements;v overheating with potential personal injury and/or property damage; andv a fracture resulting in the internal contacts being exposed, which potentiallycould subject the user to a shock hazard.For every power supply in the library, complete the following steps.1. Remove the protective label from the power receptacle on your library.2. Plug one end of the power cord ( 4 in “Connecting the Host Interface Cable”on page 4-12) into each power supply connector on the back panel of thelibrary.3. Plug the other end of each power cord into the nearest properly groundedpower outlet. Use separate power sources for each power supply for redundantpower.Attention: To disconnect all power from the library, remove the power cordfrom each outlet. The power button removes power from portions of the libraryand the drives, but the power supplies still have AC power at their inputs.4. Remove the protective plastic on the exterior surfaces of the library.a77ug197Figure 4-17. Removing the protective label from the power receptacleChapter 4. Installation and Configuration 4-13
