Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. These warnings are flagged by use of the triangular alert icon (seen below) and are listed in descending order of severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.
1 DESCRIPTION
Note: The Fiber Panel Next Generation is designed to be installed in an environmentally controlled network telecommunications facility such as a Central Office, Controlled
Environmental Vault, or Data Center.
The FPX 1RU and 2RU panels can accommodate up to 48 and 96 terminations, respectively.
Typically, the panel ships empty. The panel may also be ordered with adapter packs, Multifiber
Push-On (MPO) cassettes, splice trays, or pigtails. The panel can be configured for termination only (without splice trays) or for termination/splice.

2 BASIC INSTALLATION
Basic installation consists of procedures done for every type of FPX fiber panel, selecting the mounting bracket location and reconfiguring the brackets if desired, installing the panel on an equipment rack, installing the vertical cable guides, and grounding the panel. Instructions for these procedures are provided below.
Additional procedures, after basic installation, are required for specific types of panels. For a
table summary of these procedures, see Table 1 on Page 10
.
Warning: Never install equipment in a wet location or during a lightning storm. When installing or modifying communication lines, disconnect lines at the network interface before working with uninsulated lines or terminals.

Mounting Bracket Options
The 1RU and 2RU panels are shipped with mounting brackets installed for a 23-inch EIA/
WECO rack with a 2-inch recess. The mounting brackets can be reconfigured for a 5- or 8-inch recess. A 19-rack mount with a 2-, 5-, or 8-inch recess is also possible. 19-inch mounting
brackets are provided. Figure 5

Panel Grounding
Each FPX fiber panel has a grounding location on each side of the panel marked by a standard grounding symbol as indicated in
The lug may be mounted in either a horizontal or vertical orientation. Secure the lug using the two #10-32 ground screws and two #10 star washers provided. Route a a #6 copper grounding cable from the lug to office ground.
Note: Ground the unit to the local facility CBN (Common Bonding Network) or IBN
(Isolated Bonding Network) per local practice.
If installing an armored OSP cable, use the internal grounding stud (shown in

Installing Pigtail Adapter Pack Assemblies and Splice Trays
This section describes how to install pigtail adapter pack assemblies and splice trays in an empty panel or as an addition in a termination/splice panel where some of the adapter pack positions were left vacant at installation.
The 1RU panel accepts up to two adapter packs pigtail assemblies. The 2RU panel accepts up to four assemblies. Either stranded or ribbon pigtails may be installed. The illustrations in this section show stranded pigtails.
Use the following procedure.
1. If splice trays are present in the panel, remove them and set them aside to be re-installed in a subsequent step of this procedure.
2. Install the pigtail adapter packs as follows:
Note: “Left” and “right” directions here are as viewed from the rear of the panel.
Note: As a rule of thumb, begin with the lowest number positions in the adapter bulkhead and route to the lowest splice tray in the stack; however, when splicing ribbon adapter packs, not all of the splice trays will be required and the lowest splice tray can be used for slack, if desired. Pigtails from the right side of the adapter bulkhead should be routed around to the left in a counterclockwise direction, pigtails from the left side of the adapter bulkhead should be routed around to the right in a clockwise direction.

Installing IFC/OSP Cable and Preparing for Splicing
Allow a fiber service loop of at least 126-inches (3.5 meters) when stripping the cable sheath.
This provides sufficient length for routing the buffer tubes within the panel and for splicing.
After entry, the buffer tubes are routed to the splice tray. Use the following procedure to secure the IFC/OSP cable at the fiber entry point and to route the optical fibers into the panel.
1. Route the IFC/OSP cable to the selected entry opening at the side of the panel.
Note: Cables may enter the panel from either the top or bottom and may be clamped to either the left or right side.
2. Strip back OSP cable buffer tube approximately 66-inches (167.64 cm) to expose optical fibers. Follow cable manufacturer's recommendations when stripping the sheath.
3. Break out the OSP cable corresponding to the dimensions given in Figure 27
. Follow cable manufacturer's recommendations when stripping the sheath.

Performing a Ribbon Fiber Heat Fusion Splice
Note: In this procedure, the splice trays and splice chips are assumed to have been loaded as described in the previous sections of this user manual.
Use the following procedure to perform a splice.
1. Unwind the splice tray from the panel and set it on an adjacent flat surface.
2. Remove the splice tray cover.
3. Unwind the splice chip from the splice tray to the full extent of the fibers, and set the splice chip on an adjacent flat surface.
4. Ensure that the bare fiber lengths of the distribution and feeder fibers are as shown in
Figure 32 (distribution fiber on top) or Figure 33 (feeder fiber on top). Note that the
lengths are different for the distribution and feeder fibers.
5. Perform the splice per local guidelines.
6. For the configuration being used, wind the splice chip back into the splice tray as shown in
.
7. Replace the splice tray cover.
8. If there is an additional splice tray with a splice to be performed, set the first splice tray to the side and repeat the above steps for the additional splice tray.
9. When done with all splice trays, wind the splice trays back into the panel so that they wind up stacked in the same order as at the beginning of this procedure.

4 OPERATION
4.1
Sliding the Drawer In and Out
The panel has a tray release button and tray retainer clips designed to ensure the drawer is opened carefully and remains open until work in the drawer is competed. These items look the same and operate the same on the 1RU and 2RU panels. To release a closed drawer, press the
release button down, as shown in Figure 35 , and slide the drawer out to the retainer clip (one on
each side).
