General Safety Precautions

1 PRODUCT DESCRIPTION

1.1 General Description

The Enhanced High density (EHD) Panel is a fiber optic connector panel intended for

use in large data centers in a direct connect or interconnect environment. The EHD

Panel mounts in a 19-inch (48.26 cm) or 23-inch (58.42 cm) equipment rack with a 3-

inch or 6-inch channel. The EHD Panel will also mount in 19-inch or 23-inch cabinet.

The EHD Panel is available in 1RU, 2RU, or 4RU size. In each 1RU of rack space, a

fully loaded panel provides 144 LC (72 Duplex) terminations and/or 72 MPO ports. The

panel features slide out blades (three per 1.75 inches (4.44 cm) of rack space)

accessible from front or rear and providing full hand access to adapters and

connectors. Each blade can accommodate two adapter packs or modules.

1.2 Major Components

Figure 2 shows the main components of the EHD Panel. They are as follows:

•Blade—holds two LC-MPO modules or two MPO adapter packs; slides out toward

front or rear of the panel. There are three blades per 1RU of rack space. The

blade has a first and second position. The first position is used to plug in

connectors to the front of an adapter pack or module. The second position (further

removed from the front of the panel) is used install adapter packs and modules,

and for access to clean the rear connectors when using adapter packs.

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.

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.

Caution: This equipment is to be installed only in Restricted Access Areas (dedicated

equipment rooms, equipment closets, etc.).

Note: In this figure, the 2RU panel is shown. Main components are analogous for

other RU sizes. For comparative views of the three panel sizes, refer to Section

1.3 on Page 4.

TECP-91-008 • Rev C • January 2019

Figure 1. EHD Panel Main Components (2U Model Shown)

•Rear Cover—can be removed to allow a blade to be removed from the rear of the

panel. It is also removed to route in and secure fiber cables on the rear of the

panel.

•Grounding Location—is where a two-hole lug (not provided) and ground wire

are attached to connect the panel ground PEM nuts to office ground. The two-hole

lug to be used requires a spacing between holes of 0.625 inch (1.59 cm).

•Mounting Brackets—can be flipped around to provide either front- or rear-facing

mounting on a channel rack. The mounting brackets can be mounted with a

recess of either 3 inches (7.62 cm) or 6 inches (15.24 cm).

•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 to move the door

into its lower position allowing the lowest blade to open freely.

•Designation Label—provides physical space for recording fiber designations.

1.3 Comparative View of 1RU, 2RU, and 4RU Panel

The figures below provide comparative views of the different sizes of the EHD Panel,

as follows: 1RU panel (Figure 2); 2RU panel (Figure 3); 4RU panel, front view

(Figure 4); 4RU panel, rear view (Figure 5). Figure 6 shows the rear of the 4RU panel

with rear cover removed. The 4RU panel has a removable mid-shelf, also shown in

Figure 6.

1.4 Specifications

Table 1 lists specifications for the EHD Panel.

Note: The 4RU panel comes with a rear midshelf, shown in Figure 6. This

midshelf can be removed for easier access to the bottom blades when cabling or

for high count cables that will be terminated on both lower and upper blades. The

midshelf should be used when many trunks are terminated in the panel. The

midshelf prevents the weight of the trunks terminated on the top blades from

weighing down on the trunks terminated at the bottom of the panel thus impeding

their movement.

1.5 Transportation and Storage

Products packaged in cartons may be stacked two high in transportation and storage.

Some products packaged in spools may be stacked two high in transportation and

storage. See product packaging labels for designation.

2 UNPACKING 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 Section 7 on Page 26 if you need to contact CommScope.

3 PANEL INSTALLATION

3.1 Overview

The EHD Panel, shown in Figure 7, is mounted in a 19 inch (48.26 cm) channel rack or

cabinet. When mounting into a cabinet, it is recommended that the rear mounting rails

be 24 inches back (60.96 cm) from the front mounting rails. Trunk breakouts are

intended to come into the rear right or left side of the panel. CommScope trunks with

standard breakouts and gland adapters are the preferred method.

If required per local standards, the panel can be grounded as described in Section 3.3

on Page 10. Ground lugs and ground cables are not provided with the panel.

Caution: This equipment is to be installed only in Restricted Access Areas (dedicated

equipment rooms, equipment closets, etc.).

3.2 Mounting the Panel

The panel can be installed in a 19-inch (48.26 cm) or 23-inch (58.42 cm) equipment

rack with a 3-inch or 5-inch channel, as shown in Figure 7. Use the following procedure

to mount the panel:

1. Obtain the following tools and equipment:

• Phillips #2 screwdriver;

• Mounting hardware provided.

Figure 8. EHD Panel as Shipped

2. Select the mounting position to be used referring to Figure 7, and if required

remove and re-install the mounting brackets on the panel using the screws

holding the brackets when shipped.

3. Once the mounting brackets are located in the correct position (Figure 10):

a. Select two mounting screws from the accessory pack, and screw the two

screws into the rack bottom mounting position on each rail approximately 1.5

turns (so most of the screw shank is still out).

b. Place the open slots on the bottom of the mounting brackets onto these

screws.

c. Secure the brackets with mounting screws at higher points on the bracket.

Use the first full mounting hole for the top screw.

d. Tighten the bottom screws.

Note: The panel is shipped with the 19-inch mounting brackets at the 3-inch

recess position, as shown in Figure 8. The two 23-inch mounting/shipping

brackets mounted further back can be removed and discarded. To ease

installation, the back cover and side plate/gland adapters assemblies should also

be removed. See Section 4.5 on Page 16.
