Step 1: Check the SCSI connection Use the following questions to help you check your SCSI connection. As long as you have a spare drive bay in your server you should have a spare connection on the internal SCSI bus. You need to ensure it is the correct SCSI bus type. Most users can use HP Library & Tape Tools to check the SCSI bus type, see page 33. If you answer 'Yes' to all these questions, you are ready to install your tape drive. If you answer 'No', you will probably need to purchase and install additional items. For product details, go to www.hp.com/go/connect. 1 Is there a spare SCSI port on the server's internal SCSI bus? No? Yes? Purchase and install one of the recommended HBAs into an unused 64-bit PCI expansion slot. (The HBA can also be installed in a 32-bit PCI expansion slot, but performance may be degraded.) 2 Are the SCSI ribbon cable and HBA card rated at Ultra 3 (160) or Ultra 4 (320)? No? (Make sure the ribbon cable is terminated. See page 19.) Performance may be impaired. See table below. Consider replacing your card with one of the recommended HBAs. We recommend a 64-bit Ultra 3 (160) SCSI HBA kit. Yes? 3 Will the drive be the only device on the bus? This is the recommended configuration. No? Do not connect to a RAID controller channel. Yes 4 You are ready to install the drive. Consider installing (if you have a spare PCI slot) or replacing your card with an Ultra 4 (320) HBA. SCSI Bus Type Ultra 3 (160) LVD Ultra 4 (320) LVD Ultra 2 LVD Ultra single-ended, wide High Voltage Differential Transfer Speed Up to 160 MB/s Up to 320 MB/s Up to 80 MB/s Up to 40 MB/s Up to 40 MB/s table 1: supported SCSI bus types Supported Yes. This is a recommended configuration. Yes. This is a recommended configuration. Yes, but this is not recommended Yes, but this is not recommended as it will restrict performance. Do not connect to a narrow SCSI bus. No. The drive will not work and you may damage the drive or controller 9
