Standard Installation Procedure

Installing the External Fibre Channel Router
To install the optional external Fibre Channel router, refer to StorageNet 3300 Fibre
Channel Router User Manual, Chapter 2.
If installing an external fibre channel router to replace an internal fibre channel router
card, remove the internal fibre channel router card. Refer to the L40 Tape Library Service
Manual, PN 96026.
Connecting the External SCSI Cables
Note: You can connect the library and drives to the same bus (on bus) or to separate
buses (off bus). However, for the on bus configuration, a bus reset will affect all
devices on the bus. Library availability can be improved by ensuring that the
library is on a separate bus from the drives.
You should be familiar with SCSI principles to correctly cable your system.
The library supports the use of:
• Digital linear tape (DLT) 7000E/8000 drives on an HVD interface
• DLT 8000 drives on an LVD interface
• Ultrium linear tape open (LTO) drives on an LVD interface (native) or on an HVD
interface (with an optional converter card that is on the drive tray assembly when
ordered as HVD from Storage Technology Corporation)
• DLT1 drives on an LVD interface (native) or on an HVD interface (with optional
converter card)
To attach SCSI cables:
1. Attach a SCSI daisy-chain cable to one rear SCSI port on the drive. These cables
should be at least 300 mm (11.81 in.) if connecting from the LLC card to the top
drive slot, or 600 mm (1.97 ft) if connecting from the LLC card to the bottom drive
slot. If you have an internal Fibre Channel router installed, use the 600 mm (1.97 ft.)
cable to reach from the LLC card to the drive slots.
2. Connect the client-server cable to the library.
Note: Make sure you properly set the SCSI IDs for the drives and library, or you might
stop activity on the SCSI bus. You will set the IDs when you configure the
library and drives.
3. Install the provided terminator on the remaining SCSI port of the lowest drive that is
installed, and on the client server computer, if required:
• HVD uses terminator part 10187075.
• LVD/SE uses terminator part 10148031.
