GENERAL INFORMATION
1. THE MxU supports the 2.5 GHz TDD band and is installed in conjunction with the mid-power remote unit (MRU) (ordered
and installed separately), expanding the number of supported services to eight.
2. The MxU is installed at the remote site and interfaces the MRU.
3. Depending on the model (including AC or DC power supply module), the unit requires a 100-240 VAC or
48 VDC (30-60 VDC).
4. The MxU is intended for connection to a TN power system and IT power system of Norway only.
5. Unit is provided with two mounting options:
• 19-in rack – preassembled rack ears
• Wall-mountable – mounted onto MRU mounted on a wall (wall-mountable brackets ordered separately)
This document describes the installation and connection procedures for the Corning® optical network evolution (ONE™) solutions
mid-power expansion unit add-on (MxU).

. ADDITIONAL REQUIRED ITEMS
(NOT PROVIDED)
• Four rack-mount nuts and screws for securing unit in
communication rack (type depends on rack)
• Torque wrench for RF connectors (i.e., QMA, 4.3-10 DIN)
• Grounding tools and components:
– 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 of the switch 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
. INSTALL UNIT IN -IN RACK
Note: MxU requires 1U rack height availability
Step 1: Determine the location of the MxU in the rack
while considering additional units
(e.g., MxU, power supply). Refer to Figure 1.
Step 2: Install the unit in the rack and secure to rack
frame via applicable bracket holes using
appropriate rack nuts and screws.

. GROUND UNIT
The grounding connection is performed via a two-hole, standard barrel
grounding lug located on the left of the front panel (see Figure 2).
Prise de terre du châssis MxU
La mise à la terre est réalisée en utilisant une cosse deux trous a œillet
standard, située à gauche de la face avant (voir Figure 2).
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.
. RF AND MANAGEMENT CONNECTIONS
Refer to Figure 3 and connect the RF cables according to the
following table.
IMPORTANT!
• Keep the cable straight or adhere to the bend radius of the cable when
tightening the nuts:
– Minimum bend radius (one time): 8 mm
– Minimum bend radius (repetition): 40 mm
• Screw torque > = 5 Nm
• Make sure that the cable is not stressed when tightened
. MANAGEMENT CONNECTION
Referring to Figure 3, connect the MxU “MGMT” port to the MRU RJ45
“Exp.” Port using an RJ45 Ethernet cable.
Connect MxU Port To MRU Port Using the Provided
“UL” “Exp. UL” QMA/QMA RF cable
“DL” “Exp. DL” QMA/QMA RF cable
“Antenna Port” “2.5 GHz Input Port” 4.3-10 DIN RF Cable

. POWER UP
Notes: • The MxU PSM is located on the bottom right of the
front panel.
• The PSM type (AC/DC) is model dependent.
• Refer to section 7A for AC models.
• Refer to section 7B for DC models.
A. AC MODELS
ATTENTION!
1. Approved power cable – the entire length of the power cable (or
exible cord) and the insulation must be intact. The cable must be
rmly connected to both the electrical plug and the unit itself.
2. Standard plug – the use of a standard plug is mandatory. The use of
a non-standard power plug can cause electrocution! Also, plugging a
non-standard plug into a standard socket that does not correspond
to the plugs’ shape, can damage the socket making it a safety hazard.
Connect the MRU power connector to the AC power source using the
provided AC power cable (P/N 705900007):
• Power input: 100-240 VAC/50-60 Hz
• Power consumption: 128 W (maximum)
• Maximum AC current consumption: 2.5 A
See Figure 4 for AC connector location.
A. MODÈLES ÉLECTRIQUES AC
ATTENTION!
1. Câble d’alimentation qui est approuvé - la totalité de la longueur du
câble d’alimentation (ou cordon souple ) et de l’isolation doit être
intact. Le câble doit être bien connecté à la fois à la prise électrique
et l’appareil.
2. Prise électrique standard - l’utilisation d’une che standard est
obligatoire. L’utilisation d’un cordon d’alimentation non standard
peut entraîner l’électrocution!
De meme, brancher une che non-standard sur une prise standard ne
correspondant pas à la forme de de la che, peut endommager la Prise,
ce qui en fait un danger de sécurité.
Branchez la prise d’alimentation du MRU à la source d’alimentation
secteur à l’aide du câble d’alimentation secteur fourni:
• Alimentation: 100-240 VAC / 50-60 Hz
• Consommation d’énergie : 128 W (maximum)
• La consommation de courant maximale: 2.5 A
Voir Figure 4 pour l’emplacement du connecteur AC.

B. DC MODELS
Note: DC models include one four pin terminal block connector
which supports both NEC CLASS1 and CLASS2
• CLASS2 (default) – supported by the four pins of the DC
terminal block connector for remote feed supporting two DC
wiring pairs
• CLASS1 – supported by the rst two pins (LT-to-RT) of the DC
terminal block for local plant feed. To use CLASS1 – user must
change default connector mode from CLASS2 to CLASS1 (see
“Local plant feed – CLASS1 connector” description).
Remote feed – CLASS2 connector (default)
DC CLASS2 connector specs:
• Supported wire AWG:
– Conductor cross-section, solid (AWG/mm²):

– Conductor cross-section, exible (AWG/ mm²):
30~12/0.2~2.5
• Wire strip length: 9~10 mm
DC Power input: 30-60 VDC
Power amplier consumption per pair:
• First pair: 50 W
• Second pair: 78 W

Maximum current consumption:
• First pair: 2.1 A
• Second pair: 3.3 A
Local plant feed – CLASS1 connector:
Step 1: Open PSM captive screws and pull-out module
from chassis.
Step 2: Remove PSM-DC top panel by unsrewing the three
screws on each side panel, as shown in Figure 6.
Step 3: Disconnect DC input source type connector
and reconnect with the arrows pointing to the
“CLASS1” setting. See Figure 7.
Step 4: Close top panel and insert PSM-DC in chassis
slot.
Step 5: Route DC pair from the rst two DC CLASS1
