Installing the iRM4451
6-10 iRM4451 RRH Product Description and Installation Guide
To connect GigE optical fronthaul cables:
1. Remove the captive dust cover of the FH1 fiber optic cable entry port by turning
counterclockwise.
2. Remove the captive dust cover from the Huber + Suhner Q-XCO fiber optic cable
connector by simultaneously squeezing the lock latches on either side of the
quick-lock mating connector and turning the dust cover counterclockwise just past
where the arrows come into alignment and pull, gently but firmly.
3. Remove the four (4) dust plugs on each of the duplex fiber ends and retain for
future use.
4. Align the red arrow on the FH1 cable gland of the iRM4451 with the arrow on the
cable’s quick-lock connector and insert the Q-XCO fiber optic connector into the
FH1 bulkhead connector.
5. Twist the quick-lock connector clockwise until an audible ‘clicks’ is heard and the
arrows on the bulkhead connector and the cable connector are in alignment
indicating the connector is in the locked position.
6. If required, repeat step 1 through step 5 for the FH2 fiber optic cable entry port if
two Q-XCO fiber optic cables are used to daisy-chain or sidehaul to another
iRM4451.
NOTE
The fronthaul connections must be waterproofed using a self-fusing tape
made for that purpose. The application of the tape will vary by Operator,
so local practice will determine how the tape is applied. Refer to
Required tools on page 4-1.
6.1 Connecting the –48 V dc power cable
This section provide the procedure for connecting the –48 V dc power cable, with TE
CPC Series 5,
3-wire, circular power plug to the iRM4451 power input connector.
Recommended use type SOOW, 8/2, stranded copper conductor, indoor/outdoor,
round cable, wire rated at 600 V, or equivalent.
NOTE
Power to the –48 V dc power supply cable should be switched off at the
breaker before connecting to the iRM4451 power input connector.
To connect the dc power cable:
1. Plug the power cable plug into the power input receptacle labeled POWER located
on the bottom of the .
2. Secure the connection by hand tightening the coupling nut until you feel it ‘click’
into the locked position.
