003-948 Instruction, Centrix™ System Housing Installation
1. General
This document describes the installation of the Centrix™ System patch panel cassette into both rear- and front-
access Centrix System frames, 19-in racks, and 23-in frames. The 4U housing is shown in this instruction, but the
procedure applies to Centrix System housings of all sizes (1U, 2U, and 4U).
It is assumed that the Centrix housing has already been installed into the rack/frame according to the instructions
provided with the housing.
2. Carton Contents
• Patch panel cassette
• Right-hand jumper routing waterfall and retainer clip kit (P/N CTX-KIT-RT-DH)
3. Tools and Materials
• (Optional) Strain-relief bracket (P/N CTX-KIT-SR-SA)
4. Installation of Rear-Access Cassettes into Rear-Access Frame
Rear-access cassettes can be installed into Centrix rear-access frames, 19-in racks, and 23-in frames.
Step 1: Take note of the locations etched into the cover for the jumper inputs (Figure 1). Open the cover.
Step 2: Feed the input jumpers into the cutouts in the back of the cassette in groups of 12 according to the
number of jumpers being installed - up to 24 SC connectors or 36 LC connectors. For example, install
jumpers 1-12 into the rst cutout on the right, as viewed from the back of the cassette.

Step 3: Pass the rst 12 jumpers through the rst guide (Figure 2).
Step 4: Remove dust caps from the rear of the adapters and from the connectors. Clean the connector end
faces and adapters per standard company practices or as described in Section 7.
Step 5: Insert the connectors into the rear of the rst 12 adapters.
Step 6: Repeat Steps 1 through 5 for additional groups of 12 jumpers as shown in Figure 2.
a. For jumpers 13-24, use the middle cutout and the middle guide to hold the jumpers.
b. For jumpers 25-36, use the cutout on the left, as viewed from the back of the cassette, and the third
guide to hold the jumpers.
Figure 2
Step 7: Once all jumpers have been installed into the cassette, feed the other end of the input jumpers
through to the back of the housing, then slide the cassette into the housing, starting at the top of the
housing.

Step 8: Continue loading cassettes from the top to the bottom of the housing until it is full.
Step 9: If desired, attach up to four strain-relief brackets (CTX-KIT-SR-SA) to the housing as shown in Figure 4.
a. Route the jumpers to the strain-relief brackets and secure them with 1/3 x 6-in hook-and-loop straps
(provided).
b. Dress the jumpers with a service loop as shown in Figure 4 to provide slack to allow the cassette to be
extracted to the detent position.

5. Installation of Front-Access Cassettes in Front-Access Frame
5.1 Front-Access Cassettes with Left-Hand Input Jumper Feed
Front-access cassettes with left-hand input jumper feed can be installed into front-access Centrix frames,
19-in racks, and 23-in frames. Install the jumpers into the front-access cassettes, following the numbering
scheme on the drop handle label (Figure 5).
Figure 5
Step 1: In a 19-in rack or 23-in frame installation only, distribution jumpers may be routed out either side of
the cassette to their destination. If routing jumpers to the right, install right-hand waterfall kit (CTX-
KIT-RT-DH) to support the jumpers (Figure 6).

Step 2: Open the cover of the cassette.
Step 3: Remove the appropriate number of plugs from the
input area.
Step 4: Feed one end of each jumper through the opening
in the front of the cassette (Figure 8). In a 24-port
cassette, install eight jumpers per input. In a 12-port
cassette, install 6 jumpers per input.
Step 5: Remove dust caps from the rear of the adapters and
from the connectors. Clean the connector end faces
and adapters per standard company practices or as described in Section 7.
Step 6: Insert the connectors into the rear of the adapters.

Step 7: Once all jumpers have been installed into the cassette, slide the cassette into the housing, starting at
the top.
Step 8: Continue loading cassettes from the top to the bottom of the housing until it is full.

5.2 Front-Access Cassettes with Right-Hand Input Jumper Feed
Front-access cassettes with right-hand input jumper feed can only be installed into 19-in racks and 23-in frames,
not into a Centrix frame. Install the jumpers into the front-access cassettes, following the numbering scheme
on the drop handle label (Figure 10).
Figure 10
Step 1: In a 19-in rack or 23-in frame installation only, distribution jumpers may be routed out either side of
the cassette to their destination. If routing jumpers to the right, install the right-hand waterfall kit
(CTX-KIT-RT-DH) to support the jumpers (Figure 11).
Figure 11
Step 2: Open the cover of the cassette.
Step 3: Remove the appropriate number of plugs from
the input area.
Step 4: Feed one end of each input jumper through the
opening in the front of the cassette (Figure 13). In
a 24-port cassette, install eight jumpers per input.
In a 12-port cassette, install six jumpers per input.
Step 5: Remove dust caps from the rear of the adapters
and from the connectors. Clean the connector
end faces and adapters per standard company
practices or as described in Section 7.

6. Install Distribution Jumpers into the Front of the Cassette
NOTE: Rear-access cassettes are shown in Figures 15 and 16. Distribution jumper routing principals are the same
for front-access cassettes.
Step 1: Press latch on right side of cassette and pull cassette out to detent position (Figure 15 left).
Step 2: Press buttons on each side of the cassette and lower the handle.
Step 3: Open the handle cover (Figure 15 right).
Figure 15
Step 4: Clean adapters and connectors per standard company practices or as described in Section 7. Mate the
jumpers (Figure 16 left).
Step 5: Raise handle. Dress jumper cords to the side of the cassette (Figure 16 right).
• In a Centrix™ System frame, jumpers must route out the left side of the cassette.
• In a 19-in rack or a 23-in frame, jumpers may route to the left, to the right, or in both directions. If
routing jumpers out the right-hand side of the cassette, install the optional right-hand waterfall
kit (CTX-KIT-RT-DH) as shown in Figure 6.
Step 6: Close handle cover.
Step 7: Push cassette back into the housing and dress jumper cords in the frame as described in the
installation instruction provided with the housing.
IMPORTANT: Guide bers while inserting cassette to avoid pinching bers.

7. Connector Care and Cleaning
WARNING: Never look directly into the end of a ber that may be carrying laser light. Laser light can
be invisible and can damage your eyes. Viewing it directly does not cause pain. The iris of the eye will
not close involuntarily as when viewing a bright light. Consequently, serious damage to the retina
of the eye is possible. Should accidental eye exposure to laser light be suspected, arrange for an eye
examination immediately.
WARNING: Isopropyl alcohol is ammable with a ashpoint at 54°F. It can cause irritation to eyes on
contact. In case of contact, ush eyes with water for at least 15 minutes. Inhalation of vapors irritates
the respiratory tract. Exposure to high concentrations has a narcotic eect, producing symptoms of
dizziness, drowsiness, headache, staggering, unconsciousness, and possibly death.
• Always keep dust caps on connectors and adapters when not in use.
• Ensure dust caps are clean before reuse.
• Use optical cleaning materials as standardized by your company.
• Clean the connector before every mating, especially for test equipment patch cords (jumpers).
• A minimum level of cleaning is listed below. Local procedures may require more rigorous cleaning
methods.
Step 1: Remove plugs from the connector adapter.
Step 2: Wipe the connector ferrule twice with a lint-free wiping material moistened with isopropyl alcohol.
Then wipe across the end of the ferrule.
Step 3: Repeat previous step with a dry wipe.
