. ASSEMBLE CABLE MANAGEMENT TRAY

ONTO IHU AND CONNECT ERFC CABLE
TO RIX AND OIX MODULES

Refer to Appendix A of this document for instructions on how
to assemble the provided Cable Management Tray and connect

ERFC Cable (routed through tray).

. MOUNT CHASSIS IN -IN RACK

Notes: • IHU chassis requires 4U rack height
availability

• Rack nuts and screws not provided

Step 1: Determine the location of the IHU in the rack

while considering additional units (i.e., IHU, HEU,
OIU) and the lengths of the available ERFC cable.

Step 2: Referring to Figure 1, secure the units’ rack ears
to the rack frame as follows:

• Insert two screws halfway into the rack
frame (one on each side).

• Position the bottom half slots of the chassis
rack ears onto the screws.

• Secure the unit in the rack via all applicable
bracket holes using the appropriate rack
nuts and screws.

. INSTALL ALL MODULES

Note: For modules with ejectors (i.e., RIM, RIX, OIM, OIX,

and HCM/ACM) – verify that the ejectors are
completely open when inserting in dedicated slot
and then push in until the module clicks in to the
backplane. Figure 3 shows example of module type
captive screws and ejectors.

Step 1: Refer to Figure 2 for module locations. Remove
blank panel and slide in the relevant module
(chassis slots are 100 percent mistake proof):

• (One) HCM (for Standalone/Master IHUs)/
(One) ACM (for Auxiliary IHU)

• (One to two) PSM – for single-power-supply

installations, install the PSM in either (PSM) slot.

• (One) RIX module

• (One to eight) RIM – no need to terminate

unoccupied RIM slot.

• (One to eight) OIM

• (One) OIX module

Figure 2: Example of Occupied IHU
(Without Cable Management Tray)

Step 2: Referring to Figure 3, secure the modules to
backplane by:

• Closing the ejectors (for relevant modules)

• Tightening the captive screws

. GROUND HEU CHASSIS

hole, standard-barrel grounding lug located on the
HEU rear panel (see Figure 4).

The grounding connection is performed via a two-

. IHU EXPANSION CONNECTIONS TO
IHU, HEU, AND OIU UNITS

Notes: A single IHU supports expansion connections as
follows:

• To one additional IHU

• To one HEU and one OIU

For connections to additional IHUs or HEUs,

and OIUs:

Using the appropriate length ERFC cable

(according to distance of available OIX/RIX port)
connect remaining IHU RIX and OIX module
connectors as follows:

• Connections to additional IHU
(see Figure 5):

- IHU #1 RIX 9-Pin connector to the

corresponding IHU #2 OIX module

- IHU #1 OIX 9-Pin connector to the

corresponding IHU #2 RIX module

Figure 5: RIX to OIX Connections - Two IHUs

• Connections to additional HEUs and OIUs

(see Figure 6):

- IHU RIX 9-Pin connector to the corresponding

connector on the OIX module of the
additional OIU.

- IHU OIX 9-Pin connector to the corresponding

connector on the RIX module of the
additional HEU.

Note: The RIX and OIX modules of the additional HEU
and OIU units must also be connected.

. CONNECT RIMS TO RF SOURCE(S)

Step 2: Route the connected cables through the cable
management tray towards the right or left of the
tray (depending on the module location in
the chassis).

Step 3: Connect the RF coax cable from the RIM to the
corresponding external RF source.

Step 1: For each RIM – connect the RF coax cable to the

RIM’s simplex or duplex QMA connectors. See
Figure 7.

. RIX  MHz PILOT CLOCK CONNECTIONS

Notes: • This section is only relevant for congurations
with additional IHU or HEU and OIU units.

• The REF IN and REF OUT pilot clock ports
must be connected in a closed loop as shown
in Figure 8.

• Both RIX modules of each chassis must be

connected.

Figure 7: RIM RF Source Simplex/Duplex Interfaces

• The jumper cables are routed through the

sides of the cable management tray and door.

Referring to Figure 9, use the QMA/QMA jumper cable (PCKC47
provided with each RIX) to connect the REF OUT and REF IN ports
of each of the RIX modules in the HEU chassis.

. FIBER CONNECTIONS

Using the provided Corning MTP®-LC APC Harness Cable:

• Connect the cable MTP connector to the
OIM MTP connector.

• Remove the protective plastic covers and
connect the (3) LC APC connection bers to
the FMU Edge module LC APC connections.
See Figure 9.

Quick Installation Sheet | CMA-350-AEN | Page 6

. MANAGEMENT CONNECTIONS

Notes: • One RJ45/RJ45 management cable is

provided with each IHU.

• Refer to control nodule quick installation

sheet (CMA-348-AEN) provided with each
module for instructions on how to perform the
management connections.

• The management connections are routed to

the right via the cable management tray.

ATTENTION! Make sure there are no loop back connections to the
HCM or ACM modules! An HCM connected to an ACM cannot
have another cable connecting it back to the HCM – doing so may
cause alarm ooding resulting in a system freeze!

. POWER ON

Note: Max power consumption for fully loaded
chassis: 300 W

Figure 10: HCM LOCAL Port to ACM Port LOCAL
Management Connection

Step 1: • For PSM-AC modules – connect supplied

power cable (100-240 VAC) connector to the
PSM input connector and to the AC outlet and
switch on. See Figure 11.

• For PSM-DC modules – refer to Quick
Start Guide provided with module for

wiring pinout .

Step 2: Verify that the Power Status LED on each PSM
shows green. See Figure 11 for PSM-AC LED.

APPENDIX: ASSEMBLING IHU CABLE MANAGEMENT TRAY

Notes: • The IHU cable management tray is used for managing the unit connection cables.

• The IHU cable management tray includes a routed ERFC34 cable; Expander Cable — RF
interface cable between RIX and OIX modules; 9-pin SMP to SMP connector; L = 34 in.

• The tray can be assembled either before or after the IHU module cables are connected.

• A Phillips screwdriver is required.

Step 1. Attach Cable Management Tray to IHU Chassis

Figure A1: Assembling Cable Management Tray to IHU Chassis

Step 2. Connect ERFC cable to RIX (Slot 1) and OIX (Slot 14)
9-Pin Connector Connectors

ATTENTION! Make sure that ERFC cable is manipulated in such a
way that the 9-pin connectors properly connect to the RIX and OIX
modules and so that the cable does obstruct the module slots. Do
not remove the cable ties holding the cable in place!
