Connecting the Drive Interface and Power Cables 3 LTO-3 (Model B), LTO-4 (Model B), and LTO-5 Installing a Second Tape Drive or Replacing a Tape Drive Follow these instructions to install a second tape drive or to replace a tape drive after it has been removed. Caution: Before installing a second tape drive, you must turn off the 1U Rackmount enclosure and disconnect it from its AC power source. Preinstallation Requirements Before installing a second tape drive in the 1U Rackmount enclosure, make sure you have the following required tools and parts: Tools 3/16 in. [. . . ] a SAS cable Note: Ensure that a 4-pin Molex power connector is plugged into the power inputs of the SAS cable as shown in Figure 16. Figure 16 Connecting the SAS and Power Cables (LTO-5 Only) SAS cable 4-pin Molex power connector Re-installing the Top Panel To re-install the top panel (see Figure 17): 1 Install the top access panel on the 1U rackmount enclosure and slide toward the front of the rackmount enclosure. 3 Tighten the latch screw to secure the top access panel to the 1U rackmount enclosure.

Two internal 2-port SCSI cables are installed in the enclosure and ready for tape drive connections depending on your configuration. · Connecting Two Drives per SCSI Bus · Connecting One Drive per SCSI Bus Connecting Two Drives per SCSI Bus Use the configuration shown in Figure 18 when connecting both tape drives to the same SCSI bus. 12 Installing a Second Tape Drive or Replacing a Tape Drive LTO-3 (Model B), LTO-4 (Model B), and LTO-5 Figure 18 Connecting Two Drives on One SCSI Bus SCSI bus 1 cable SCSI ID cables, one for each tape drive SCSI terminator Tape drive 1 Tape drive 2 Note: When adding a second tape drive for configurations using a single SCSI bus, unplug the SCSI cable from tape drive 1, pass the end of the cable through the internal rackmount enclosure openings, and connect the end port to tape drive 2. The SCSI terminator is at the end of the cable and should be behind tape drive 2. Note: Each SCSI device on the same SCSI bus must have a unique SCSI ID. Be sure that the SCSI ID is different for each tape drive and that neither is set to SCSI ID 7. Connecting One Drive per SCSI Bus Use the configuration shown in Figure 19 when connecting each tape drive to a separate SCSI bus.

Caution: To avoid damaging the equipment due to electrostatic discharge, be sure to practice ESD procedures when handling the tape drive. 14 Installing a Second Tape Drive or Replacing a Tape Drive LTO-3 (Model B), LTO-4 (Model B), and LTO-5 Installing the 1U Rackmount Enclosure in a Rack The rack rails supplied with the 1U rackmount enclosure can be used to install the unit in racks that have round, square, or threaded holes in the vertical mounting bars. The rails are identical and may be mounted on either the left or the right side. Figure 20 Rail Mounting Kit Components Outer rack rails Cable support clips 3 Inner rack rails Fasteners Tools Required If you are installing the tape enclosure in a rack with unmarked holes in the vertical mounting bars the following items will make the rack installation easier: · Pencil · Tape measure If you are installing the tape enclosure in a rack with threaded holes in the vertical mounting bars you will need the following tool: · 3/16 in. The rails are shipped ready for installation in racks with round or square holes. If the rails are to be installed in racks with 10-32 threaded holes, the mounting pins must first be removed. Refer to the following sections for installation instructions for your rack type: · Installing in a Rack with Round or Square Holes · Installing in a Rack with 10-32 in. Threaded Holes Installing in a Rack with Round or Square Holes To install the 1U rack enclosure in a rack with round or square holes: Note: The ends of the rack rails are marked FRONT and REAR for proper orientation. 1 Insert the pins in the front mounting plate of the outer rack rails into the previously marked holes in the front vertical mounting bars of the rack (see Figure 22). The rack rails will lock securely into place.

(see Figure 23). The rack rails will lock securely into place when the end of the rails are pushed forward. 18 Installing the 1U Rackmount Enclosure in a Rack LTO-3 (Model B), LTO-4 (Model B), and LTO-5 Figure 23 Installing the Rack Rails in the Back of the Rack Spring-loaded tab FRO NT Note: To remove the rail for repositioning, push the spring-loaded tab on the outside of the rack rail and slide rearward.
