2.4 DRU Mounting Procedure
The DRU may be mounted on any flat vertical or horizontal surface. Aslot is provided in each
of the four mounting feet for inserting afastener. The fasteners must be provided by the
installer. Use the following procedure to mount the DRU:
Warning:Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically-powered equipment. To prevent electrical shock, never install
or use electrical equipment in a wet location or during a lightning storm.
Note: To insure that all optical connectors and transceivers remain dust-free during installation,
leave all dust caps and dust protectors in place until directed to remove them for connection.
1. Obtain the appropriate fasteners (lag bolts, screws, wall anchors, etc.) for securing the
DRU to the mounting surface.
2. Position the DRU on the mounting surface in the specified location (per the system
design). Make sure the LED will be visible when the unit is mounted.
Note:To ensure there is adequate air circulation for cooling, provide aminimum of 3
inches (76 mm) of clearance space on all sides of the DRU (except the bottom). In
addition, at least one surface of the DRU installation area must be open to the building’s
interior air space. If aportable/flexible antenna will be installed, allow aminimum of 9
inches (229 mm) clearance along the surface with the antenna.
Note:In mounting situations where fiber, power, and coaxial cable pass-through holes
are planned, it is critical that these holes be placed far enough away from their respective
connectors to avoid forming overly tight bend radii. Tight bend radii can damage fiber
optic cable and reduce RF signal levels. The DRU mounting template (part # 1154319)
provides the clearances for the following cable types:
Power cable (cat 3 and 5): 0.2 inch (5.2 mm) diameter
Fiber optic cable (twin lead): 0.12 inch (3.0 mm) diameter
Antenna coaxial cable: 0.16 inch (4.0 mm) diameter
If planned cable diameters are greater than those listed, please consult with the cable
manufacturer to determine the cable’s recommended minimum bend radii.
3. Mark the location of the mounting holes and of any pass-through holes that may be
required for fiber, power, or coaxial cables. Observe any additional instructions that may
be printed on the template such as the recommended fasteners and clearance
requirements.
4. Drill appropriately sized holes in the mounting surface for the mounting screws or wall
anchors and for the fiber, power, or coaxial cables (if pass-through holes are required).
5. Place the DRU in position for mounting and then install the fasteners as shown in Figure 7.
6. Securely tighten each fastener.

2.7 Optical Connection
The optical interface between the DRU and the DHU or DEU is supported by a small form
factor LC-type optical transceiver which is mounted on the DRU front panel. One side of the
transceiver provides the optical fiber connection for the forward path (downlink) signal. The
other side of the transceiver provides the optical fiber connection for the reverse path (uplink)
signal. Use the following procedure to connect the forward and reverse path optical fibers to
the DRU:
Danger:This equipment uses aClass 1Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do
not look directly into the optical transceiver of any digital unit or exposure to laser radiation
may result. An optical power meter should be used to verify active fibers. Aprotective cap or
hood MUST be immediately placed over any radiating transceiver or optical fiber connector
to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents
dirt particles from entering the transceiver or connector.
1. Locate the forward and reverse path optical links that were routed to the DRU from the
DHU or DEU.
Note:The procedures for routing the forward and reverse path optical links from the

2.8 DC Power Connection
The DC power interface for the DRU is supported by an RJ-45 female connector located on
the DRU front panel. The DRU is powered by nominal 48 Vdc power which may be provided
by the DHU, DEU, or by an AC/DC converter (accessory item). Use whichever of the
following procedures is appropriate for the installation.
2.8.1 Power Provided by the DHU or DEU
Use the following procedure to connect the DC power cable when the DRU is powered by the
DHU or DEU.
1. Locate the DC power cable that was routed to the DRU from the DHU or DEU.
Note:The procedures for routing the DC power cable from the DHU or DEU to the DRU
are covered in either the Digivance ICS Installation and Operation Manual (ADCP-75-
110), which is provided with the DHU, or the Digivance ICS Digital Expansion Unit
Installation Instructions (ADCP-75-111) which is provided with the DEU.

2. Connect the DC power cable to the 48 Vdc connector on the DRU (see Figure 16).
3. Locate the AC power cord which is provided with the AC/DC power converter. Use only the
AC power cord provided with the power converter or an equivalent UL/CUL listed and
certified 3-conductor, 18 AWG cord terminated in amolded-on plug cap rated 125 V, 15 A
with amaximum length of 6feet (1.8 m).
Note:The AC/DC converter is intended to be used with a 3-wire grounding type plug
which has a grounding pin. Equipment grounding is to ensure safe operation. Do not
defeat the grounding means. Verify converter is reliably grounded when installed.
4. Connect the receptacle end of the power cord to the AC connector on the AC/DC
converter (see Figure 17).
5. Route the plug end of the power cord to the specified AC outlet (per the system design)
and connect plug to outlet.
Warning:Be sure to check the nameplate rating of the AC/DC converter to avoid overloading
circuits which may cause damage to over-current protection devices and supply wiring.
6. Verify that the STATUS LED on the DRU turns red or blinking red. This indicates that
the DRU is powered but not receiving a forward path optical signal.
Note:Early versions of the DRU use asteady red LED to indicate all major fault
conditions including no optical signal received. Later versions of the DRU use ablinking
red LED to indicate no optical signal received.
7. Dress and secure both power cables per standard industry practice.
8. When the installation of the DRU is completed, refer to Section 4of the Digivance ICS
Installation and Operation Manual (ADCP-75-110) for the system turn-up and test procedures.
