Introduction
The 2T-QINTL-TL interlock kit contains the components for installing the slide assemblies, the interlock system,
and the shipping bracket on the rackmounted tape library. The interlock system helps prevent cabinet instability by
allowing only one system at a time to be pulled out of the cabinet. The shipping bracket is used to secure the tape
library in the cabinet during shipment or when moving the cabinet to a new location.
The interlock system consists of a vertical rod, on which are mounted actuator latches for each product installed in
the cabinet. These actuator latches engage the interlock actuator on the rear of rackmount systems. When a
rackmount system is pulled out of the cabinet, the actuator latches rotate to prevent any other rackmount system that
has an interlock actuator from being pulled out of the cabinet.
Table 1 lists the parts that are shipped with the 2T-QINTL-TL interlock kit. The callouts in column 1 refer to the

Installing the Slide Assemblies
The rackmount tape library requires 35.56 cm (14.00 in.) of vertical space or 24 contiguous holes in a 48.26-cm (19-
in) EIA cabinet. The bottom hole in this installation area (4) is identified as hole 1 and the top hole is identified as
hole 24 (see Figure 1).
In the following installation procedures, directions are referred to while viewing the rackmount tape library from the
front of the cabinet. To install the slide assemblies, refer to Figure 1 and the following procedures:
1. Remove the inner races from the right and left slide assemblies. Set the inner races aside.
2. Attach the right front slide bracket  (P/N 12-44537-01) to the right slide assembly with two 8-32 pan-head
screws  , flat washers  , split washers  , and 8-32 hex nuts  .
3. Attach the right rear slide bracket  (P/N 12-44537-02) to the right slide assembly with two 8-32 pan-head
screws  , flat washers  , split washers  , and 8-32 hex nuts  , but do not tighten.
4. Attach the left front slide bracket  (P/N 12-44537-01) to the left slide assembly with two 8-32 pan-head
screws  , flat washers  , split washers  , and 8-32 hex nuts  .
5. Attach the left rear slide bracket  (P/N 12-44537-02) to the left slide assembly with two 8-32 pan-head screws
 , flat washers  , split washers  , and 8-32 hex nuts  , but do not tighten.
6. Place the right front slide bracket  on the inside of the right front rail and align two holes of the M6 nut bar 
with the two slide bracket holes and with the 2nd and 4th holes of the installation area on the right front rail.
Install two M6 screws (3) in the 2nd and 4th holes of the installation area to secure the right front slide bracket
to the right front rail.
7. Place the right rear slide bracket  on the inside of the right rear rail and align two holes of the M6 nut bar 
with the two slide bracket holes and with the 2nd and 4th holes of the installation area on the right rear rail.
Install two M6 screws (3) in the 2nd and 4th holes of the installation area to secure the right rear slide bracket to
the right rear rail. Tighten the two 8-32 pan-head screws  and 8-32 hex nuts  that secure the right rear slide
bracket to the right slide assembly.
8. Place the left front slide bracket  on the inside of the left front rail and align two holes of the M6 nut bar 
with the two slide bracket holes and with the 2nd and 4th holes of the installation area on the left front rail.
Install two M6 screws (3) in the 2nd and 4th holes of the installation area to secure the left front slide bracket to
the left front rail.
9. Place the left rear slide bracket  on the inside of the left rear rail and align two holes of the M6 nut bar  with
the two slide bracket holes and with the 2nd and 4th holes of the installation area on the left rear rail. Install two
M6 screws (3) in the 2nd and 4th holes of the installation area to secure the left rear slide bracket to the left rear
rail. Tighten the two 8-32 pan-head screws  and 8-32 hex nuts  that secure the left rear slide bracket to the
left slide assembly.
10. Attach the right inner race to the right side of the tape library chassis and the left inner race to the left side of the
tape library chassis.
11. Pull both slide assemblies out fully to their locked positions, then lift the chassis and position it so that the inner
races fit into the front end of the slide assemblies. Push the chassis into the slide assemblies until it stops, then
release the two locking levers and push the chassis all the way into the cabinet.
Installing the Interlock System
In the following installation procedures, directions are referred to while viewing the rackmount tape library from the
rear of the cabinet. To install the interlock system, refer to Figure 1 and the following procedures:
1. Mount the interlock actuator  on the lower right rear of the tape library chassis using two 6-32 truss-head
screws ¡ .
2. Remove the screws securing the vertical rod’s bottom mounting bracket to the cabinet and slide the mounting
bracket off the bottom of the vertical rod.
3. Slide the stabilizer bracket ¢ for the new product onto the bottom of the vertical rod.

3
4. Slide the actuator latch  for the tape library onto the bottom of the vertical rod.
5. Replace the vertical rod’s bottom mounting bracket and install the screws removed in step 2 but do not tighten
them.
6. Position the stabilizer bracket ¢ so that the bottom hole in the stabilizer bracket is aligned with the 12th hole of
the installation area and the top hole in the stabilizer bracket is aligned with the 15th hole of the installation area
on the right rear cabinet rail.
7. Place the nut bar  behind the right rear cabinet rail and install and tighten the two 10-32 truss-head screws 
provided to secure the stabilizer bracket ¢ .
8. Position the actuator latch  to properly engage the interlock actuator, and tighten the two 6-32 set screws to
secure the actuator latch to the vertical rod.
9. Now tighten the screws to secure the vertical rod’s bottom mounting bracket.
