A. RACK-MOUNT INSTALLATION
Notes: • The HX 2.5 GHz TDD unit requires 4U rack
height availability.
• Rack nuts and screws not provided (depend
on rack type)
• For installations with MA1000/MA2000
remote:
• The EPM (1U) should be installed
beneath the HX 2.5 GHz TDD unit in
order to facilitate the connections
• A 2U separation distance between the
EPM and the top of the MA1000/
MA2000 remote unit is required
Step 1: Determine the location of the HX 2.5
GHz TDD in the rack. See Figure 2 for rack
installation example.
Step 2: Secure the unit to the communication racks’
vertical uprights as follows (see Figure 3):
• Insert two screws halfway into the rack
frame.
• Lift the unit using the side handles and
position the bottom half slots of the rack
ears onto the screws.
• Secure the unit in the rack via the
remaining applicable six bracket holes
using the appropriate rack nuts and screws.
B. WALL-MOUNT INSTALLATION
IMPORTANT!
• The wall-mount installation procedures in this
section are for concrete/brick walls. For other wall
types, installer is responsible for following standard
practices using the appropriate tools and materials.
• When selecting the installation location, make sure
that there is enough clearance distance from the
bottom to open the HX 2.5 GHz TDD chassis door.

B. WALL-MOUNT INSTALLATION (CONTINUED)
Step 1: Remove the factory-assembled rack ears from
the sides of the unit.
Notes: • If the HX 2.5 GHz TDD is to be installed in
conjunction with the EPM, the latter must be
assembled to the HX unit before mounting
the unit on the wall - refer to Steps 2 and 3.
If not, continue to Step 4.
• Additional required tools and materials:
• Phillips/electric screwdriver
• Six UNC 6-32, 5/8-in (15.8 mm) screws
used for mounting EPM onto HX 2.5 GHz
TDD
• Four anchors for mounting brackets on
wall (anchor type depends on surface
type).
Step 2: Six xed holes on top of the EPM are used for
mounting the unit onto the 2.5 GHz TDD. See
Figure 4.
Step 3: Place the EPM onto the top of the HX 2.5 GHz
TDD unit and using six UNC 6-32, 5/8 (15.8
mm) screws, assemble the EPM onto the HX
2.5 GHz TDD unit. See Figure 5.
Step 4: Using ten UNC 6-32, 11 mm screws for each
bracket (provided in HX kit), assemble the
wall-mount brackets to the sided of the HX
2.5 GHz TDD as shown in Figure 6 Step.
Step 5: Referring to bracket hole dimensions in
Appendix A: Wall-Mount Bracket Dimensions
(units in mm), prepare the appropriate
anchors and mount as follows:
• Mark four holes (minimum of two on per
bracket) on the wall for drilling the anchors.
• Drill four holes, using a hammer drill.
• Fill the holes with silicon to help weather-
proof the drilled holes and to prevent
erosion.
• Tap in expanding lead shield anchors.
Step 6: Insert two bolts in top anchors and tighten
until bolt head is 0.5-in from surface of wall.
See Figure 7.

Step 7: Hang the unit and bracket assembly onto the
two bolts using the key holes.
Step 8: Insert remaining bolts (two on each side)
through remaining bracket holes into anchors.
Step 9: Tighten all four bolts.
Step 10: Verify that HX 2.5 GHz TDD unit is tightly
secured and does not shake.
Refer to Figure 8 for wall-mount examples
with additional MA2000 remote.
. GROUNDING CONNECTIONS
Required tools and components:
The following additional (not supplied) tools and components are
required for connecting the system ground:
• Grounding wire - grounding wire should
be sized according to local and national
installation requirements. The provided
grounding lug supports 14 AWG to 10 AWG
stranded copper (or 12 AWG to 10 AWG solid)
wire conductors.
Note: The length of the grounding wire depends on
the proximity to proper grounding facilities.
• Phillips-head screwdriver
• Crimping tool to crimp the grounding wire
to the grounding lug.
• Wire-stripping tool to remove the insulation
from the grounding wire
Step 1. Use a wire-stripping tool to remove
approximately 0.4-in (10.9 mm) of the
covering from the end of the grounding wire.
Step 2. Insert the stripped end of the grounding wire
into the open end of the grounding lug.
Step 3. Crimp the grounding wire in the barrel of the
grounding lug. Verify that the ground wire is
securely attached to the ground lug by holding
the ground lug and gently pulling on the
ground wire.
Step 4. Prepare the other end of the grounding wire
and connect it to an appropriate grounding
point at the site to ensure adequate earth
ground.

Connect from… To…
HX 2.5 GHz TDD “WB RU” N-Type
duplexed port
HX4 (ANTENNA PORT) “Port 1”
N-Type duplexed port
Note: • For SISO installations, the connections are
from HX 2.5 GHz TDD ANT 1 (MUX) “WB
RU” port to the HX4 “ANTENNA PORT 1”
• For MIMO installations, the MIMO 2 Stream
connections are performed between the HX
2.5 GHz TDD ANT 2 (MUX) “WB RU” port
and the HX4 “‘ANTENNA PORT 2”
Step 2. Connect broadband antenna coax to the HX-2.5
GHz TDD MUX module “ANT” port (two for MIMO
models) and to broadband DAS antennas. Refer
to Figure 11.
ATTENTION! Terminate any unused RF ports with a

. RF CONNECTIONS TO HX WCS
Step 1. Perform the WCS service connections as follows:
Connect from… To…
HX 2.5 GHz TDD “WCS RU” mini
DIN 4.3-10 type
duplexed port
HX WCS “ANT” mini DIN 4.3-10

Notes: • For SISO installations, the connections are from
HX 2.5 GHz TDD ANT 1 (MUX) “WCS RU” port to
the HX WCS ANT 1 (MUX) “ANT” port.
• For MIMO installations, the MIMO 2 Stream
connections are performed between the
HX 2.5 GHz TDD ANT 2 (MUX) “WCS RU” port
and the HX WCS ANT 2 (MUX) “ANT”port.
Step 2. Connect broadband antenna coax to HX-2.5 GHz
TDD MUX module “ANT” port of (two for MIMO
models) and to broadband DAS antennas. See

REMOTE
Notes: • The RF connections between the HX 2.5 GHz
TDD unit and an MA1000/MA2000 remote
require an EPM unit (interfaces MA1K/
MA2K SCU).
• Two EPM units are required for MIMO
installations.
Step 1. Connect the HX 2.5 GHz TDD MUX “ANT” mini
4.3-10 type duplexed RF port to the EPM front
panel high-band mini DIN 4.3-10 input port, as
shown in Figure 13.
Step 2. Connect the four rear panel EPM low-band
N-type input ports to the corresponding SCU
N-type ANTENNA PORTS”. See Figure 14.
Notes: The location of the SCU “ANTENNA PORTS” differs
depending on model:
• SCU-4/SCU-8 units - antenna ports located on
rear panel
• SCU-F/SCU-FT - antenna ports located on
front panel
Step 3. Connect the four EPM rear panel Mini DIN 4.3-10
“ANT” output ports to the wideband antennas.
See Figure 14.

connections and interfaces to the OCH-WDM
located at the headend via the ber patch
panel.
• HX 2.5 GHz TDD supports connections to
OCH-WDM, whereas the HX4 and HX WCS
support connections to BUs.
Open cabinet door to access HX 2.5 GHz TDD module(s) with the
ber optic interface, route the DL and UL bers through the front
door slot (see Figure 15) and connect the ber optic cable pigtails
from splice box, leading from the OCH port, to the corresponding
HX 2.5 GHz TDD module SC APC “Optic Port” (MIMO models include
two service modules with ber connections).

. POWER UP
WARNING! Before connecting or disconnecting ground or power wires
to the chassis, ensure that power is disconnected from the DC circuit.
To disconnect power, locate the circuit breaker on the panel board
that services the DC circuit, and switch the circuit breaker to the OFF
position. Verify zero voltage at the power terminals on the chassis
before proceeding.
DC power specications
• Power source rating: 34-48 V DC
• Max. Consumption: SISO = 90 W; MIMO = 150 W
• Compatible wire size for plug: 30~12 AWG
• No. of required pairs: Minimum of three pairs (up to four)
• Max. current consumption for connector:
for 20 AWG = 4.5 A; (max. 5A)
Step 1: Make sure power switch is OFF!
Step 2: Open cabinet door, if not already open, to access
power supply unit (PSU).
Step 3: Connect the DC wires leading from the power
source to the Dinkle 2ESDFM terminal block plug
according to indicated pin out on the PSU DC
