Important safety admonishments are used throughout this manual to warn of possible
hazards to persons or equipment. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times.
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.
General Safety Precautions
Caution: When mounting equipment in the rack make sure mechanical loading is even
to avoid a hazardous condition, such as loading heavy equipment in the rack unevenly.
The rack should safely support the combined weight of all equipment it supports.

and 110-18 of the National Electrical Code, ANSI/NFPA 70.
1PRODUCT DESCRIPTION
1.1General Description
The SYSTIMAX Enhanced High Density (EHD) Panel is a pre-terminated fiber optic
connector panel intended for use in large data centers in a direct connect or
interconnect environment. The SYSTIMAX EHD Panel mounts in a 19-inch (48.26 cm)
equipment rack with a 3-inch or 5-inch channel. In each 1RU of rack space, a fully
loaded panel provides 144 LC terminations using duplex LC adapters.
The SYSTIMAX EHD Panel is designed for ease of installation and access. It is
available with either left- or right-side cable entry. The panel features sliding blades
(three per 1RU of rack space), providing full access to adapters and connectors. Each
blade can accommodate four adapter packs. The SYSTIMAX EHD Panel is available
with either a black or sky white baked enamel exterior.
1.2Major Components
Figure 1 shows the main components of the SYSTIMAX EHD Panel. They are as
Note: In this figure, the 2RU panel is shown. Main components are analogous for
other RU sizes.
• Blade—holds adapter packs or cabled modules; slides out to two front access
positions and is removable from front. There are three blades per RU rack space.

• Fiber Cover—holds down fibers on each blade to prevent them from being
inadvertently snagged or misrouted.
• Grounding Location—is where a two-hole lug and ground wire are attached to
connect panel ground PEM nuts to office ground. A two-hole lug is provided with
the product; the ground wire is not.
• Mounting Brackets—can be flipped around to provide either front- or rear-facing
mounting on a channel rack.
• Front Door—swings down to provide access to the interior of the panel. The door
features a double hinged design that allows users to open the door without
interfering with equipment below the panel on the same rack, or also to allow the
door to lay flat for easy access to the bottom blade.
• Designation Label—provides physical space for recording fiber designations.
• Duplex LC Adapter Pack—(shown for reference) mounts within the blade.
Product offerings for adapter packs include LC adapter packs in singlemode APC
or UPC style.

2UNPACKING AND INSPECTION
1. Inspect the exterior of the shipping container(s) for evidence of rough handling
that may have damaged the components in the container.
2. Unpack each container while carefully checking the contents for damage and
verify with the packing slip.
3. If damage is found or parts are missing, file a claim with the commercial carrier
and notify CommScope Customer Service. Save the damaged cartons for
inspection by the carrier.
4. Refer to Topic 7 on Page 22 if you need to contact CommScope.
5. Save shipping containers for use if equipment requires shipment at a future date.
3UNPACKING A PANEL WITH A PRETERMINATED CABLE
The pre-terminated panel is shipped with the panel mounted on top of a spool
containing the cable. The stub end of the cable is unwound to a splice vault or other
point of termination. To protect the panel and cable windings contained within the
upper cylinder of the shipping unit, It is critical to leave the foam packaging material
surrounding the panel in place until the unit has been transported to the final
installation location. Transporting the unit without the foam packaging in place may
result in damage to the panel and/or cable. To unpack and mount a fully loaded panel,
use the following procedure.
Caution: This equipment is to be installed only in Restricted Access Areas (dedicated
equipment rooms, equipment closets, etc.) in accordance with Articles 110-16, 110-17,
and 110-18 of the National Electrical Code, ANSI/NFPA 70.
4.1Overview
The SYSTIMAX EHD Panel is shipped on a spool, preterminated with 144 LC
connectors per rack unit (RU). It is available in both left- and right-cable-entry versions.
A blocking kit is provided for the purpose of splicing the provided cable into a splice bay
such as the OMX.
After mounting, the panel must be grounded. Use a #2 Phillips Screwdriver to tighten
the M4 screws through the ground lug (provided) into the panel ground PEM nuts, as
described in
Topic 4.4 on Page 15. Ground cables are NOT provided with the panel.
4.2Tools and Hardware Needed
Use a #2 Phillips Screwdriver and the supplied #12-24 screws to secure the panel to
the equipment rack.
4.3Mounting an Unloaded Panel
The panel is to be installed in a 19-inch (482.6mm) equipment rack with a 3-inch or 5inch channel. Use the following procedure to mount the 1RU/2RU panel.
1. Obtain the following tools and equipment:
• Phillips #2 screwdriver;
• Mounting hardware provided.
Note: The panel is shipped with the mounting brackets already installed in the
front position. If a rear position is desired, remove the brackets and install them in
the rear position.
2. Determine whether the panel will be installed on front or rear and whether on a 3inch or 5-inch channel. Install the mounting brackets provided in the locations
shown in the following figures (which are representative of other RU sizes, also):
• Figure 11 for 2RU mounting on a 5-inch channel;
• Figure 12 for 2RU mounting on a 3-inch channel;
• Figure 13 for 1RU mounting on a 5-inch channel; or

3. Hold the panel up to the assigned mounting space and align the holes in the
mounting brackets with the holes in the equipment rack as shown in
Secure the panel to equipment rack using the #12-24 screws provided. Torque
these screws to approximately 27 pound-inches (3.1 Newton meters).

4.4Grounding the Panel
A termination (for an M4 screw) is provided on the panel for a frame ground
connection. The connection must be made in accordance with local and national
electrical codes. Use the following procedure, referring to
1. Locate the ground location on the panel. At the grounding location, remove the
protective tape from the panel.
2. Using AWG 14 (1.6mm) solid copper wire, secure a crimp lug to one end of the
ground wire (installer provided). Secure the crimp lug to panel with two M4
screws. Torque the screws to approximately 15 pound-inches (1.7 Newton
meters).
Caution: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit.
3. Connect the other end of the ground wire to the earth ground conductor. Ensure
this connection is made using methods and hardware that meets all applicable
local and national electrical codes.
Pre-terminated SYSTIMAX EHD Panels use RBR G657.A1 reduced-bend-radius
singlemode fiber.
when testing and splicing the RBR G657.A1 fiber to the G.652 standard singlemode
fiber.
Please alert contractors to this fact.
The minimum cable bend radius is 10 inches (25.4 cm).
CommScope recommends the following type patch cords for use in the SYSTIMAX
