. 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 moduleswith 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

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

The grounding connection is performed via a two-

hole, standard-barrel grounding lug located on the

HEU rear panel (see Figure 4).

- For use with stranded copper wire conductors

- 10-14 AWG

- Holes –1/4 in

. 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

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

RIM’s simplex or duplex QMA connectors. See

Figure 7.

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.

. 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.

• 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.

. 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

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.

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!
