Option 3: Connect cable to port on host SAS controller and replace existing SAS cable IMPORTANT: This installation uses the appropriate Infiniband or Mini-SAS cable to replace the existing SAS cable and requires a spare PCI slot on the rear of the server to accommodate the cable. Always refer to http://www.hp.com/go/connect BEFORE installing your tape drive. The following instructions are valid for some HP ProLiant servers, but ONLY IF recommended as an option on http://www.hp.com/go/connect. This installation diverts the wiring from one of the hard disk drive bays to the tape drive. You should be aware that you may lose the use of a hard disk drive bay with this cabling solution. Cable routing varies from one server to another. You may need to remove other components, such as fan banks, while you work with the cable. Always refer to your server documentation for server-specific cabling instructions. CAUTION: Static electricity can damage electronic components. Always wear an antistatic wriststrap if one is available. If not, after you have disconnected power from the server and removed the cover, touch a bare metal part of the chassis. Similarly, touch a bare metal part of the drive before installing it. 1. HP strongly recommends that the tape drive is connected to the second SAS port on the host controller (this is the port that connects to the hard disk drive bays with the highest numbers). Look at the front of the server and establish which SAS cable is connected to the hard disk drive bays with the highest numbers. 2. If http://www.hp.com/go/connect advises that you will lose the use of a hard disk drive bay, also identify the location of that disk drive. NOTE: If the hard disk drive bay is in use, do not use the internal cable (even if other disk bays are empty), because you will lose use of the disk in the disk drive bay and may damage your server configuration. Also, do not move an existing disk to accommodate this configuration because you will need to rebuild your RAID configuration. Instead, purchase and install an additional HBA, see http://www.hp.com/go/connect for supported products. DAT SAS Tape Drives 49
