ProLiant 1850R Interlock Kit Installation Information
EK-1850R-IN. A01
May 1999
Introduction
The 2T-QINTL-18 interlock kit contains the components for installing the slide assemblies, the interlock system,
and the shipping bracket on the rackmounted ProLiant 1850. 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
ProLiant 1850 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-18 interlock kit. The callouts in column 1 refer to the part

1. Remove the inner races from the right and left slide assemblies . Set th e inner races aside.
2. Attach the right front slide bracket (P/N 74-53881-01) 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 74-53881-02) 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 74-53881-02) to the left slide assembly with two 8-32 pan-head
screws , flat washers , split washers , and 8-32 hex nuts .

, flat wash ers , 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 the slide bracket hole with the
2nd hole of the installation area on the right front rail. Install an M6 screw in the 2nd h o le 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 the slide bracket hole with the
2nd hole of the installation area on the right rear rail. Install an M6 screw in the 2nd hole 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 the slide bracket hole with the
2nd hole of the installation area on the left front rail. Install an M6 screw in the 2nd hole of th e 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 the slide bracket hole with the 2nd
hole of the installation area on the left rear rail. Install an M6 screw in the 2nd hole 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.
