2.1 Introduction
The JPM418A-R5 is 2U high, fits in a 19" or 23" rack, and supports 6 adapter
panels or LGX Cassettes. Depending upon the number of fiber ports on the
adapter panel or cassette, you can have up to 144 fiber optic connections
in this rackmount enclosure. It supports standard fiber adapter panels or fiber
cassettes, depending upon the installer application.
The fiber rackmount cabinets are constructed of 16-gauge cold-rolled steel, which
is compact and rugged enough for many commercial applications. Its black
powder-coated finish provides a professional look for any data center and it‘s also
corrosion resistant. The cabinet has a front PLEXIGLAS
a front cable management bar and several entry/exit holes, cable distribution
rings, and Kevlar® clamps to support the installer’s needs. Sold separately, this
enclosure can support up to 4 splice trays inside the chassis. One splice tray can
accept up to 12 single-mode fiber splices.

Installing Fiber in the Chassis
The installer can use Fiber Adapter Panels or LGX style cassettes in this chassis or a
combination of both. Typically, distribution cable is used with fiber adapter panels
or MTP® MPO-style connectors fiber trunk assembles are used for LGX cassettes.
LGX Style Cassettes
1. Open the front PLEXIGLAS door and slide the internal tray forward.
2. On an LGX-style cassette, pull back the two buttons for installation and choose
a location on the internal bracket where you want to install the cassette.
3. Load up to 6 LGX cassettes in the chassis depending upon your application.

4. Open the rear metal door with the two thumbscrews and let it hang
downward.
5. Connect the MTP MPO-style connectors trunk assembles to the cassette from
the rear of the chassis.

your MTP MPO-style fiber connectors trunk assemblies to the cassette from
the rear.
6. Organize your trunk assemblies with the supplied cable ties.
7. Attach the identification label sticker to the rear door on the inside of the
cabinet.
Distribution Style Fiber Cable

2. On the fiber adapter panels, pull back the two buttons for installation and
choose a location on the internal bracket where you want to install them.

Loosen the Kevlar clamp’s two screws and wrap the cable’s Kevlar yarn around
the clamp. Tighten the screws to secure the multi-strand distribution fiber to
the cabinet.
NOTE: The Kevlar clamp mounts on the left or right back of the cabinet.
7. Terminate the fiber optic connectors on the multi-strand distribution fiber cable,
or make the splice as needed. (See Figures 1 and 2 for a typical cable
