1.2.5 Miscellaneous
1.2.5.1 RSSI Alignment Cables
A digital voltmeter is used to measure the RSSI voltage changes of the receive signal level during
alignment. Two cables, one for each AireLink™ 60 radio unit, are provided with the shipment. The
cables are terminated on one side with a 2-pin female connector for attachment to the AireLink™ 60
waterproofed IP67 RSSI voltage connector located at the side of the radio enclosure. At the opposite
side the cable has banana plug connectors for attachment to a digital voltmeter (see Fig. 1-11).

1.2.5.2 Lightning/ Surge Protection
When using the PoE powering/management option and/or the copper data port rather than the fiber
data port option, we strongly recommend using a surge protector to protect networking equipment
attached to the radio to suffer from potential lightning strikes. In case of the PoE/management port, a
10/100 Mbps solution with built in PoE power protection will be sufficient. To protect the 1000 Mbps
copper data port connection, a GbE capable surge protector solution must be used. Figure 1-14 (left)
below shows examples of Ethernet surge protector in an outdoor rated and weather resistant enclosure
made
by Enable-IT http://www.ethernetextender.com/ethernet-extension-products/lightning-
protection/265LP.php .
The device in the left of Figure 1-12 is an outdoor rated GbE and PoE+ capable Ethernet lightning/surge
protector (LightPointe part number LM-SURGE-1). LightPointe recommend to install a lightning/surge
protector close to the AireLink radio head to prevent damage to the indoor networking equipment that
is connected to the radio head via CAT5/6 copper cable.
In case the direct two wire 48 Vdc powering option is used, we also strongly recommend using a surge
protector to prevent potential lightning strike surges to enter the in-building power plant. The device
on the right in Figure 1-12 is a 48 Vdc surge protector made by Transtector (
Transtector DCOD 48-2.5)
