3.5 Antennas
The radome on top of IBR houses transmit and receive antennas that face outward through
the flat sides of the radome. The direction in which the antennas are pointed can be changed
only by changing the orientation of the IBR itself. The CLI-based pointing tool can be used as
an aide to orient IBR for best link performance.
IBR is not designed to be used with external antennas.
3.6 Gigabit Ethernet Ports
IBR is a 4-port Ethernet switch. Three Gigabit Ethernet ports are exposed externally, and one
is connected internally to the radio. Beginning with the port nearest the LEDs, the external
Gigabit Ethernet ports are numbered 0, 1, and 2 (ge0, ge1, ge2).
The Gigabit Ethernet port that is connected to the radio (not externally available) is identified
as Gigabit Ethernet 3 (ge3). Radio parameters are configured through the radio 0 interface,
while switching parameters that apply both to the physical Gigabit Ethernet ports and the
radio port, such as VLAN, QoS, and CoS, are configured through the Gigabit Ethernet interface.
3.7 Interfaces
Ethernet interfaces, including loopback interfaces, can be created, as discussed in the CLI
Guide, and each port can be assigned to one or more interfaces.
3.8 External Ethernet connectors
o All three of the Ethernet connectors on the bottom of IBR can be used for traffic and
IBR management data, but only the one nearest the LEDs (ge0) can accept PoE
+
.
o There are two variants of IBR: one has three RJ-45 connectors and the other has one
RJ-45 (for ge0) and SFP

connectors for ge1 and ge2.
o The RJ-45 connectors will accept shielded and bonded RJ-45 type mating connectors
with a weatherproof seal. It is essential that only weatherproof connectors be
connected to IBR.
3.9 LEDs
Two weatherproof LEDs that are mounted adjacent to ge0 provide a visual means for an
operator to determine the status of IBR. Both LEDs can be deactivated via CLI command.
See the CLI Guide for detailed information. When the LEDs are active (the default condition):
o The upper LED (when the LEDs are on the left from the viewer’s perspective) will be
green when an active Ethernet link is established between IBR and another device.
This LED will be dark if no Ethernet link has been established.
o The lower LED will turn green when power is applied to IBR.
4. Preconfiguring IBR
The following procedure is for preconfiguring a pair of IBRs prior to installation.

CAUTION: When power is applied, the radios automatically will begin transmitting.
