CommScope AMP NETCONNECT MRJ21 User manual

Figure 1
MRJ21 48–port straight patch panels are designed to
be mounted onto a standard 483–mm [19–in.]
Electronic Industries Alliance (EIA) rack or equipment
cabinet as shown in Figure 1. AMPTRAC patch panels
are designed for use with the
AMP NETCONNECT® AMPTRAC system. Read these
instructions thoroughly before starting installation.
AMPTRAC Retrofit Kit 1479951–1 can be installed onto
the standard patch panel to enable the patch panel to
be connected to the AMP NETCONNECT® AMPTRAC
system. Back Cable Manager Kits 1933352–[ ] must be
used to support the cable.
Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.
Each 10/100BASE–T patch panel contains four
MRJ21 receptacles (one per 2 6 RJ45 connector
assembly), and each 10/100/1000BASE–T patch
panel contains eight MR21 receptacles (two per 2 6
RJ45 connector assembly). The ports are identified
by numbers printed on the front and on the back of
the patch panel. Four 12–24 screws are included to
mount the patch panel to the rack. In addition,
AMPTRAC patch panels have a sensor pc board
subassembly and two HDP–22 connectors to enable
the patch panel to connect to the
AMP NETCONNECT® AMPTRAC system.

Shielded patch panels are designed to protect the
internal electronic components from electromagnetic
interference (EMI).
1. Using the screws, mount the patch panel onto
the rack. Refer to Figure 1.
2. Plug a connector (from the trunk cable) into
each MRJ21 receptacle (at the back of the patch
panel). Refer to Figure 2. Make sure to align the
keying features of the connector and receptacle.
Ensure that the connector is fully seated,
then
using a small cross–recessed tipped screwdriver,
turn the jack screws of the connector
clockwise
and tighten to a maximum torque of 0.23 Nm
[2 lbf–in.].
3. For AMPTRAC patch panels, plug the connector
of an I/O cable assembly (PN 1499507–[ ]) from
the analyzer into each HDP–22 connector (at the
back of the patch panel). See Figure 2.
4. Install the retro–fit kit onto the rack according to
Instruction Sheet 408–10170. Using cable ties or
similar fasteners, attach the cables to the tie–down
bar. It is recommended to maintain a minimum
bend radius of 50.8 mm [2 in.] when securing and
routing cables. See Figure 2.
For port–to–cable pair cross–reference, refer to
Figure 3.
