iRM4451 RRH Product Description and Installation Guide 3-3
3.1 iRM4451 boards and modules
The iRM4451 Remote Radio Head is an integral unit with no user accessible boards or
modules.
3.2 iRM4451 controls, indicators connectors and components
There are no controls on the RRH. The connectors are located on the bottom of the
unit. They are for Global Positioning System antenna (GPS), Power (–48v DC), RF
(ANT 1–4), Fronthaul (FH1/FH2), Ground ( ), and Remote Electrical Tilt (RET).
LEDs for Fronthaul 1 (FH1), Fronthaul 2 (FH2), STATUS, and POWER are located on
the side of the unit and are visible when the solar shield is installed.
Connector locations for RF input/output are shown in Figure 3-3. Connector locations
for –48V dc Power and Remote Electrical Tilt are shown in Figure 3-4. Connector
locations for GPS antenna and fronthaul are shown in Figure 3-5.
