iRM2249nn00-1 iRRH Product Description and Installation Guide
Physical description
The isolated input allows the iRRH to be connected with a 2-wire or 3-wire
supply. Altiostar recommends a 2-wire connection with the +ve connection
referenced to chassis ground at the power connector. This is indicated in Figure
3-7 –48 V DC 2-pin Rosenberger bulkhead jack on page 3-8. To facilitate the
2-wire connection, the supplied cable connector has the positive cable terminal
connected to the connector body.
The Rosenberger 99S73B-199N1 cable connector supports the 2-wire
connection. If an isolated supply (3-wire connection) is required, then an
alternative Rosenberger 99S73J-199N1 cable connector is available.
The mating plug (Rosenberger 99S73B-199N1) is fastened by turning the
coupling nut clockwise 1/4 turn by hand until it 'clicks' into the locked position.
To remove the power plug, twist the coupling nut counter-clockwise 1/4 turn.
The iRM2249 comes supplied with an unconnectorized Rosenberger plug
(99S73B-199N1) in a kit (Figure 3-8 Rosenberger –48 V DC power plug
(exploded view) on page 3-9). The Installer assembles the cable onto the plug.

The RET cable and connectors is a standardized AISG RET Control Cable
available from many vendors. Installer supplies and installs RET cables in
lengths according to site requirements.
The RET cable can be daisy-chained to other antennas served by the iRM42249
iRRH if the option is provided by the RET motor manufacturer. Antenna RET
control is facilitated within the EMS user interface.
The Installer is responsible for providing and pre-assembly of the standardized
RET cable and connector in a length according to site requirements.
3.2.6 Fronthaul connectors
Two Gigabit Ethernet (GigE) optical SFP fronthaul ports provide connection for
up to two duplex multi-/single-mode optical GigE cables. The GigE ports,
labeled FH1 and FH2, are located on the bottom of the iRM2249 iRRH (see
Figure 3-4 iRM2249 iRRH GPS and fronthaul connectors location on page 3-5).
Connector FH1 is intended for fronthaul support. FH2 is used to daisy-chain
sidehaul support to up to one other iRM2249.
NOTE
Altiostar recommends the use of MM SFP module from Finisar – 
PN: FTLF8519P3BTL or SM SFP module from Finisar – 
PN: FTLF1318P3BTL for the FH1 and FH2 GigE ports.
The macro iRRH is shipped with Rosenberger Fiber Enclosure (RFE) flange (PN
98Z405-K00)—a bulkhead connector with captive dust cover—installed. The
mate to the flange is the RFE ‘plug’ (Rosenberger PN 98Z105-S00) which
contain the two duplex optical GigE fiber cables and protects the fiber
connections. One (1) RFE plug is provided with the macro iRRH. They are
UL94-V0 and IP67 compliant at–40° to 158° F (–40° to 70° C).
To assemble the Rosenberger RFE plug, the threaded sealing nut is first routed
onto the fiber cable, followed by installation of a split grommet and clamping
claw onto the fiber itself (see Figure 3-11 Rosenberger RFE fiber-optic
enclosure on page 3-13 for the order of RFE assembly). The fiber cable/split
grommet/clamping claw assembly is then pressed and seated into the plug
body. Approximately 3–5 in (76–127 mm) of fiber cable, including the duplex
fiber plug, should extend beyond the outside after the RFE ‘plug’ assembly is
assembled.
The RFE plug is assembled by screwing the threaded sealing nut clockwise
until it seats into position, hand tight, on the plug body. This completes the
assembly of the RFE plug. The fiber connector is then inserted into the SFP
fiber module, which is recessed in the iRRH fronthaul port, until it ‘clicks’ into
position. Any slack fiber cable is stored inside the RFE plug. The RFE alignment
rails on the RFE plug are engaged now with the bulkhead connector. When
pushed in firmly, it ‘clicks’ into place and is locked onto the bulkhead connector
3-12
iRM2249nn00-1 iRRH Product Description and Installation Guide
Physical description
completing the installation. The RFE cannot be removed because the latch
function has been disabled by the obstruction at the latch pivot when seating
the threaded sealing nut.
To remove the RFE plug from the bulkhead connector, the plug housing must
be turned counter-clockwise until obstruction of the release latches on either
side of the plug body, has been cleared. Finally, pressing on both latches at the
same time and pulling the plug body removes the RFE from the bulkhead
connector.
For assembly instructions of the Rosenberger Fiber Enclosure, refer to
Assembly instructions for Rosenberger Fiber Enclosure on page A-4.

The dust covers over the FH1 and FH2 flanges should remain in place until the
GigE optical Ethernet cables are connected and on any unused port. The dust
covers are keyed to ensure proper installation. To remove the dust cover, just
pull it off. The dust covers are re-installed in the opposite manner.
The recommended GigE fiber optic cable (x2) is OM1 62.5/125, military fiber
cable, with dual LC/dual LC termination, 10.0 m in length and is provided by
L-Com (part no. FODLCMIL-10, or equivalent).
NOTE
Remove the dust cap only when ready to connect the cable to the iRM2249.
The GigE optical fronthaul cables are supplied and pre-installed at the site by

4.2 Required site equipment
This section describes the additional interconnecting equipment required for the
installation of the Altiostar Networks iRM2249. These are essentially cables,
connectors and fixing arrangements. The specification of these items may need to
be customized on site by the Installer (specifically the type and length of cables).
Refer to Table 3-2 iRM2249 iRRH connectors on page 3-6 when ordering and
customizing the following items:
•
Grounding cable between the iRRH and the local grounding point. Altiostar
Networks provides the two-hole lug for crimping onto the cable.
•
Power cable between the iRRH and local DC supply. Installer must provide
suitable lightning and surge suppression devices on the power line to the unit
(minimum 20 kA-rated device recommended). We recommend one lightning
and surge suppressor be installed close to the iRRH on the tower/pole/wall and
one on the cable entrance just before it enters the facility.
•
Optical fiber cables between iRRH and transport network.
Other than lightning and surge suppression devices, Table 4-2 iRM2249 iRRH
Installer-supplied parts list on page 4-4 provides a list of the Installer-supplied
interconnection equipment required to install the iRM2249.
NOTE
Some parts have an order lead-time of up to 10 weeks. It is important that

6 Installing the iRM2249
This section provides the procedure for installing the iRM2249 macro iRRH in remote
locations such as on towers, poles, masts, walls, roofs, or other structures utilizing a
universal mounting assembly.
Instructions for making connections to external interfaces, cabling, grounding and
power are also provided.
6.1 Assembling cables
The Installer will need to order, pre-assemble, and pre-install various cables to the
iRM2249. Refer to Required site equipment on page 4-3.
6.1.1 Verify Installer-supplied –48 V DC power cable
The Installer supplies and pre-assembles the –48VDC power connection cable.
Use an 8 AWG minimum, round, 2-wire shielded cable rated at 600 V
minimum. The power cable length should be decided based on the position of
the iRRH and the DC power supply. Ensure the voltage input at the iRRH power
supply connector to be in the range of -40VDC to -58VDC. The maximum
length of the power cable should not exceed 100m to minimize the voltage
drop across the cable.
The female plug (Rosenberger PN 99S73B-199N1), for assembly of the DC
power cable, is provided with the iRM2249 iRRH. The connection configuration
for the supply side of the power cable is determined by site specific
requirements.
6.1.2 Verify Installer-supplied GigE optical cable
The recommended GigE fiber optic cable is OM1 62.5/125, military fiber cable,
with dual LC/dual LC termination (L-Com PN FODLCMIL-xx, or equivalent,
where xx=length of cable in meters). The Installer is responsible for ordering
this cable in the appropriate length according to site requirements.
One (1) RFE plug (Rosenberger PN 98Z105-S00) is provided with the macro
iRRH. The fiber-optic cable and dual mode fiber connector is housed inside the
RFE plug. The RFE plug is essentially a shroud covering the connected fiberoptic connector and SFP optical module inside the bulkhead on the bottom of
the iRM2249 to conform to an IP67 standard, completing the weatherproof
seal.
The RFE plug is pushed firmly into the fronthaul port flange on the bottom of
the iRM2249 until it clicks into the locked position.

6.12 Weatherproofing cable connections
This section provides the procedure for additional weatherproofing of all cable
connections (power, RET, RF, fronthaul, and alarms) to ensure a weather-tight
cable connection is maintained.
Procedure 6-12 To weatherproof cable connections
1. Weatherproof all cable connections by completely wrapping the cable, the
connector on the cable, and the connector threads on the equipment itself with
self-fusing tape (refer to Required tools on page 4-1) as shown in Figure 6-10
Weatherproofing connections using self-fusing tape on page 6-14, or according to
local practice.
NOTE
To ensure a weather-tight connection, be sure to wrap the entire connection
with self-fusing tape. Refer to the recommended taping procedure in Section
6.12.

TIP: It can be hard to remove the self-fusing tape from the connection after it
has weathered over time. To make it easier to remove the self-fusing tape, first
wrap the connection with electrical tape, such as Scotch Super 33+ (or
equivalent) before wrapping the first layer of self-fusing tape.
