Antenna waveguide flange on RAy unit (located across the holder) ensures perfect microwave connection between the unit and the antenna. RAy3 link requires use of external parabolic antenna for each RAy unit – both for physical mounting as well as for the wireless transmission itself. Parabolic antennas from different producers are available.

It is possible to use any other SFP module with power consumption up to 1.25 W, but RACOM cannot guarantee their complete compatibility with RAy units. Important SFP module has to be inserted to out-of-power unit, otherwise its function is unpredictable and the module and/or the RAy unit can be damaged.
Page 20: Dc Power (Using Eth1+Poe)
Product 1.3.3. DC power (using ETH1+POE) Direct DC power source can be used to power the RAy3 unit. Instead of standard DC connector the DC cable is mounted to a terminal block on DC/RJ45 adapter (item OTH-DC/RJ45 The adapter is then fitted in to the RJ45 connector in slot ETH1+POE.
Page 21 Other valid possibility how to power the unit using DC power source is to use passive PoE in- jector or active PoE power supply with DC input and deliver the power to RAy3 unit over PoE through Ethernet cable with RJ45 connector plugged in to ETH1+POE slot as described in Section 1.3.1, “RJ45 connector (ETH1+POE)”.

RACOM always tries to ship all ordered accessories together with RAy units and antennas. Accessories are mostly small items, so typical RACOM packaging is that all accessories are shipped on the same palette with other material (within one additional RAy box).

RAy units. There are only a very few accessories which has to be purchased from RACOM to work properly - e.g. WiFi adapters (the reason is limited set of WiFi drivers in RAy FW). Such an information is always part of accessory description. With most types of accessories it is possible to use other components with same or similar functionality and temperature range, but RACOM cannot guarantee they will be completely compatible with RAy units.

Default settings for L and U units are chosen to allow delivered units to automatically establish a link without unpacking RAy3 units from the box. It is enough to open the boxes and power both RAy units up (by PoE or DC power supplies). It allows users to comfortably set up basic parameters necessary for the installation in the lab and thus shorten the time on the tower or roof to a minimum.
