Scope
Scope
The purpose of this document is to describe how to prepare the indoor–to–
outdoor or device-to-device cables used for the BreezeMAX Extreme Base
Transceiver Station (BTS) unit.
Two power feeding options are available for the BreezeMAX Extreme BTS:

PoE (Power over Ethernet) - This feeding option is relevant only for
BreezeMAX Extreme models with up to 21dBm Tx power. In this case, a
PoE indoor-outdoor cable is required as detailed in section1 below.

Direct 48V DC - This feeding option is relevant for all BreezeMAX
Extreme models. A DC Cable is required as described in section 3.
DATA Cable is also required to connect the BTS to the backhaul as
described in section 2.
2
PoE Cable
To prepare a PoE cable, use either the cable kit available from Alvarion or
one of the authorized indoor-outdoor CAT 5E cables listed in Table 3 below,
and follow the wiring and assembly instruction as detailed herein. The
Alvarion’s cable kit includes an RJ-45 connector and a protective cover for
the connector.
1. Check that the O-ring is mounted on the sealing gland. Release slightly
the top nut on the sealing gland until the sealing gland can be moved
freely on the cable.
2. Connect the cable to the Ethernet connector of the outdoor unit.
3. Attach the sealing gland to the outdoor unit. Verify that the O-ring is in
place and tighten the screws to ensure proper sealing.
4. Tighten the top nut of the sealing gland.
5. Route the open end of the cable to the location intended for the indoor
unit.
6. Insert the protective RJ-45 cover on the cable.
7. Use a standard crimp tool to prepare the wires. Insert them into the
appropriate pins of the RJ-45 connector, and use the tool to crimp the
connector. Figure 1 shows the wire pair pin-to-pin connections required
for the indoor-to-outdoor cable (see the drawing on the back of this
page). Make sure you take back the shield drain wire before inserting
the cable into the RJ-45 connector, to ensure a good connection with
the connector’s shield after crimping.

IMPORTANT
At the BTS side there is no boot, therefore you must use just the sealing gland as stated
above; however at the LAN side there is one boot present so you must use it according to the
connector assembly procedure described below.

Data Cable
To prepare a Data cable, use either the cable kit available from Alvarion or
one of the authorized indoor-outdoor CAT 5E cables listed in Table 3 below,
and follow the wiring instruction as detailed herein. The Alvarion’s cable kit
includes an RJ-45 connector and a protective cover for the connector. This
cable should be used when the power is fed through the DC 48V connector.

DC Cable
To prepare a DC cable, use one of the authorized DC connectors listed in
Table 5 or Ethernet cables for DC power listed in Table 7 below. The power
cable is supplied with a specially designed sealing gland that should replace
the existing gland provided with the BreezeMAX Extreme BTS. Cables are
available either open-ended at the Power Supply side or with a crimped DType connector.
Follow these steps to connect the DC power cable:
1. Remove the existing gland from the 48V connection on the BTS.
2. Attach the DC power cable with the already assembled gland to the 48V
connection on the BTS.
3. Separate the sealing gland nut from the gland body.
4. Use the dedicated tool to fasten the gland to the BTS.
5. Use the dedicated tool to fasten the sealing gland's nut on the gland
body.
6. Connect the other end of the power cable to the high power AC/DC
power supply. Use a recommended power cable to connect the BS to
48V DC power source.

CAUTION
ONLY experienced installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate government regulatory
authorities should install outdoor units and antennas. Failure to do so may void the equipment
warranty and may expose the end user or Service Provider to legal and financial liabilities.
The manufacturer and its resellers or distributors are not liable for injury, damage or regulation
violations associated with the installation of Outdoor Units or antennas.

GPS Chaining Cable
To prepare a GPS chaining cable, use one of the authorized Ethernet cables
as for DATA detailed in Table 7 above. Cables are available either openended at one side or with a crimped RJ45 connector in the pricelist. The
GPS chaining cable should be crimped as straight (pin-to-pin).
Follow these steps in order to connect the GPS chaining cable
7
Grounding the Ethernet Cable
1. Remove the existing gland from the GPS master BTS device from the
GPS OUT port. This should have the external GPS receiver antenna
connected and more than 4 satellites discovered.
2. Insert the crimped cable through the gland and fasten using the
fastening tool provided with the BTS to prevent water ingress.
3. Remove the gland from the first GPS slave BTS device and insert the
other crimped connector. Fasten the gland properly to ensure water
ingress. Verify if the GPS and 1PPS LEDs lights up. Please refer to the
system manual for more information regarding the GPS chaining
configuration guidelines.

The following paragraphs describe one method for grounding the outdoorrated Category 5E Ethernet cable through its drain wire. The actual
connection method employed is left to the professional installer.
Follow these steps to ground the Ethernet cable:
1. Strip back about one inch (2.4 cm) of the Ethernet cable jacket to
expose the drain wire.

Figure 8: Exposing the Drain Wire
2. Attach a grounding cable to the drain wire and then connect it to
protective earth.
3. Use weatherproof tape to cover and seal the attachment area of the
Ethernet cable.
