Quick guide
1. Product
RAy3 microwave units work as a wireless Ethernet point-to-point link in a full duplex setting with
transfer speeds of up to 1010 Mbps. The link is formed by two RAy units, each equipped by its own
parabolic antenna and accessories to be fully operational.
1.1. Main characteristics
Supported are several license-free bands and several licensed bands, all in the identical aluminum
box. Bandwidth can be configured from 3.5 up to 112 MHz for standard bands (all models up to 42
GHz) and from 62.5 up to 2000 MHz for E-band (71-86 GHz). Modulation can be fixed or adaptive and
for standard bands it can be adjusted from QPSK to 4096QAM. In the case of E-band modulations
range from 2PSK up to 128QAM. The lowest modulation on each model could be on the fly (without
data loss) strengthened for higher receiver sensitivity by extremely robust FEC – such modulation is
marked as QPSK_S or 2PSK_BW/4_S (where 'S' means a strong FEC and 'BW/4' means a narrower
channel used in E-band only). RAy3 microwave links operating in 17 and 24 GHz bands can also be
operated as a Short Range Device (SRD).
Fig. 1.1: RAy3 – Microwave link
1.1.1. Hardware concept
RAy product line has been designed to have minimum possible number of hardware variants. Function-
ality of the unit is upgraded according to the "pay-as-you-grow" concept only by activating the relevant
software feature keys and does not require any on-site hardware changes. For details see Section 1.7,
“Ordering codes” and Section 5.6.1.2, “SW feature keys”.
HW models are determined only by frequency bands and in the case of licensed bands (i.e. 10, 11 and
18 GHz) also by sub-bands. Additionally in 10, 11, 18 and 80 GHz bands units forming a link differs in
HW duplexer which ensures the proper frequency separation of transmitting and receiving channels.
This is marked on each unit as Lower (L) or Upper (U) in Production code according the position of
transmitting channel.
11© RACOM s.r.o. – RAy3 Microwave Link
Product
Units for 17 and 24 GHz does not have any HW difference between L and U units, because transmitting
and receiving channels are freely defined by software and technically separated from each other by
cross polarization.
Cross polarization means that one side of the link uses one polarization for transmission (e.g. hori-
zontal) and the opposite polarization for receiving (e.g. vertical). The other side of the link is turned by
90°. Therefore it transmits and receives using opposite polarization with respect to the second unit.
Practical result for users is that units for 17 and 24 GHz must be mounted with reverse polarity on both
ends of the link.
Note
All units for 17 or 24 GHz band are hardware identical. Default factory settings in the pair use
different channels for L and U unit, so the link could be established by using default radio
parameters.

Product
1.1.3. SW concept
RAy is a typical Software Defined Radio product line, where all possible technical features are defined
by the internal software (SW). This internal software is distributed to users in a form of unit firmware
(FW) developed by RACOM to optimally manage all hardware inside the unit.
The strategy is to have one common FW version to support all RAy3 models for all bands and sub-
bands. It ensures that every advance in the SW development (i.e. every new feature or every bug-fix)
is immediately available on all RAy3 units. Temporary exceptions (like a separate FW version for 10
and 80 GHz units) are sometimes necessary, due to the complexity of SW development.
1.1.4. Network concept
RAy links support only the Ethernet type of traffic and they are transparent for IP and UDP packets.
Practically all protocols pass through unmodified including MPLS, RSTP (BPDU frames) and many
others, except following:
• Management packets targeted for RAy units itself
• Special packets for protocols explicitly mentioned in this manual, which are somehow processed by
RAy units (like PTP)
• Packets, which did not went through and were discarded due to capacity limitation and/or policy rules
(e.g. PIRL, QoS, EGRES shaping ...)

1.2. Mechanical interfaces
This chapter describes basic properties of each RAy unit, which are important for its mechanical install-
ation: antenna waveguide, unit fixing (screws, etc.) and unit grounding (screw + cable). Other interfaces
(for data, power and service purposes) are described in next chapters Ethernet + power interfaces and
Service interfaces.
1.2.1. Antenna waveguide
Antenna waveguide flange on RAy unit (located across the holder) ensures perfect microwave connection
between the unit and the antenna. All RAy units are equipped with identicaly sized round flange (with
the outer diameter 50 mm and the inner diameter 28 mm). The only visible mechanical difference
between RAy models are the diameters of the round waveguide hole in the middle of the flange. Those
diameters differs according frequency ranges and are following:
19.00 mm10-11 GHz
11.00 mm17-18 GHz
8.00 mm24 GHz
3.18 mm70-80 GHz
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 antennas1from different producers are available.
Fig. 1.2: Waveguide pivot and flange
Important
Each antenna has to be equipped by a corresponding RACOM RAy antenna waveguide inter-
face - the metallic pivot (28 mm diameter) with a rubber O-ring on it, otherwise the signal
to/from the unit can not be transmitted from/to the antenna and such a link would not work.

Product
Before assembling RAy unit with antenna, always carefully lubricate both antenna waveguide
pivot and RAy waveguide flange with thin layer of silicone grease to prevent the damage of
O-ring and surfaces. Pivot fits smoothly in to the flange, if it is properly lubricated. A box with
silicone grease is packaged with each delivery of new units - see Section 1.6.3, “Packaging”.
Note
If O-ring is injured or damaged, please exchange it immediately for a new one (size 22x2 mm,
type 'FPM80'), otherwise moisture + dust can leak into the waveguide and emitter. It may
eliminate several dB of signal and cause a corrosion.
Antennas from Jirous, LEAX Arkivator and Shenglu ordered for RAy mounting are automatically
equipped by RACOM RAy waveguide interface and are ready for mechanical fixing of RAy
unit to the antenna.
Antennas from other vendors has to be equipped by a proper antenna adapter first. The adapter
must be mounted on the antenna before the RAy unit can be mounted on it.
All available antennas and adapters are listed on RAy web pages in section Accessories >

1.2.2. Unit mounting
RAy unit is mechanically fixed to the antenna by 4× M8 screws (one per each side of RAy unit).
Installation and basic adjustment of the antenna is described in the Section 4.2, “Antenna mounting”.
Attaching RAy unit to it by 4× M8×30 (Allen) screws delivered with each antenna or each mount kit is
described in the Section 4.3, “RAy Unit mounting”. For adjusting the exact antenna direction see Sec-
tion 4.7.2, “Directing antennas” .
Fig. 1.3: Antenna and RAy3 unit
Note
Antennas from Jirous, LEAX Arkivator and Shenglu ordered for RAy mounting are automatically
equipped for mechanical fixing of RAy unit (including the delivery of 4× M8×30 Allen screws).
Adapters for antennas from other vendors always contain proper mechanical fixing of RAy unit
(including the delivery of 4× M8×30 Allen screws). The adapter has to be mounted to the an-
tenna first, the RAy unit is then mounted on this adapter.
All available antennas and adapters are listed on RAy web pages in section Accessories >
Antennas3.
1.2.3. Grounding screw
Fig. 1.4: Grounding screw
Grounding screw is used for a proper grounding of the RAy unit, which
is necessary for its function (ensured by galvanic connection to the
grounded mast through a grounding cable).
One M8 screw (with standard 6-edge head) is delivered with each RAy
unit. Grounding screw has two possible positions (two holes) to be
mounted in. Those are located near the left and right fixing screws of the
RAy unit and both are marked by a yellow grounding symbol and both
are equivalent (second hole remains unused). For more information
about unit grounding see Section 4.3.3, “RAy unit grounding”.

Note
Grounding screw function is to ensure proper grounding of the RAy unit (by a grounding cable),
not for mechanical fixing of the unit.
1.2.4. Pressure equalization
Fig. 1.5: Pressure equalization screw
Pressure equalization between outside and inside of RAy
unit is an important technical requirement. It is realized by
a small plastic screw next to ETH2 label. It ensures the
pressure equalization without letting moisture or humidity
to enter the unit.
Important
Do not manipulate or remove this small plastic
screw. It is part of the cabinet and its manipulation
or a deformation can damage the water protection
of the unit.
Warranty does not apply for units with this screw
missing or deformed.

1.3. Ethernet + power interfaces
This chapter describes interfaces for user data transfer and power sourcing of the unit, as described
on the picture and characterized in the table below. Remaining interfaces for service purposes are
described in next chapter Service interfaces.
Fig. 1.6: Slots ETH1+POE, ETH2
FunctionSlot
Gigabit metallic Ethernet + Power over Ethernet (PoE) port
ETH1+POE This port is capable of powering the unit with active or passive PoE power source
or with direct DC.
Slot for user exchangeable SFP module
ETH2
A wide range of fibre optics Ethernet modules is available. Both single or dual
mode transceivers can be used. SFP module with metallic RJ45 interface can also
be used.
The SFP LED
Located on SFP, just next to connectors. It is controlled by SFP module. Its function
is specific for each SFP module. The typical behavior is an indication the received
signal from the optical or metallic link to be within operational range.
Note
A set of all necessary bushing parts are delivered with each RAy unit - see a description of
this standard basic accessory ACS-RAy34. Additional bushing options for installation of longer
connectors or other equipment are available as well. For bushings installation see Section 4.4,
“Connectors assembly and disassembly”.
Important
All bushings and plugs (including the original plugs in the flanges) must be fitted with O-rings
and carefully tightened. Otherwise, the unit is not protected against moisture intake through
connectors and cannot offer guaranteed functionality.

1.3.1. RJ45 connector (ETH1+POE)
Fig. 1.7: RJ45 Ethernet connector
RJ45 socket connector marked „ETH1+POE“ is a standard
10/100/1000Mbps metallic Ethernet port.
This port is also used for power sourcing the unit by PoE
(Power over Ethernet) or direct DC power source. Both an
active PoE power supply (compliant with IEEE 802.3at re-
spectively IEEE 802.3bt standards known also as PoE+
respectively PoE++) and a passive PoE power supply (with
wider voltage range than PoE) are supported.
Supported PoE types of power sourcing are:
•Active PoE requires PoE power supply compliant with
standards IEEE 802.3bt or IEEE 802.3at (the second
one only for RAy3-17 and RAy3-24) and the reasonably
quality Ethernet cable, otherwise the proper function of
the unit can't be guaranteed. The norm defines supplied
voltage in the range 37-57V (for PoE+) respectively 51-
57V (for PoE++) and max current typically 0.55-2.0 A.
•Passive PoE can operate in extended voltage ranges
which depends on the maximum power consumption of
each model:
○20 to 60 V for 10, 17 and 24 GHz units (for unit boot at least 21 V to prevent booting with discharged
24 V battery)
○37 to 60 V for 11, 18 and 80 GHz units
○Any polarity of DC and PoE inputs are supported.
Note
Extended voltage ranges and polarities are identical with direct DC power sourcing described
in Section 1.3.3, “DC power (using ETH1+POE)”.
Maximum long-term voltage on the unit is recommended to be below 58 V (to ensure over-
voltage protection inside the unit stays deactivated).
RJ45 connector pins are wired according standards IEEE 802.3bt (utilizes 4 pairs = 8 wires) and
IEEE 802.3at (utilizes 2 pairs = 4 wires). All units support all PoE modes of operation:
• Mode A: pins 1,2 (V+) and 3,6 (V-)
• Mode B: pins 4,5 (V+) and 7,8 (V-)
• Mode A+B: all 8 pins with numbers identical to Mode A and Mode B
Note
Additionally to IEEE norm all units can be powered by PoE or DC with opposite +/- polarity.
PoE with 8-wires is strongly recommended for 10, 11, 18 and 80 GHz units due to their power
consumption >25 W. PoE with 8-wires is recommended also for other models to minimize the
energy lost in the Eth cable (it lowers the resistance of the Eth cable to half compared with 4-
wires PoE).

Product
Galvanic separation: All contacts of RJ45 connector are galvanically separated from RAy unit. It
ensures galvanic separation for any kind of PoE power supply as well as for DC power sourcing
(made through OTH-DC/RJ455).
Important
The shielding of the Ethernet cable has to be properly grounded near the unit to ensure
proper unit connectivity and resistance against over-voltage. Suitable grounding kit (for example
items GND-CAT7 or GND-CAB-UNI6or similar) has to be applied and connected to the mast
or to the Grounding screw on the well grounded unit chassis (for example by the item GND-
RAy7).
More information about usage and installation of available power options can be found in
Section 4.6, “Power supply” and Section 4.5, “Grounding and overvoltage protection”.
Note
One plastic RJ45 plug for CAT5e and CAT6 cables is delivered with each unit (within item
ACS-RAy38), ready to be punched to an Ethernet cable.
Higher quality and CAT7 compatible RJ45 plugs are available to be purchased as well (for
example item CON-RJ45-CAT79).
1.3.2. SFP slot (ETH2)
Fig. 1.8: SFP slot
„ETH2“ is a standard SFP slot for 10/100/1000 Mbps Eth-
ernet SFP modules, user exchangeable. In the case of 80
GHz unit the SFP slot supports also SFP+ standard, so
2.5/5/10 Gbps SFP+ modules can be used as well. Both
fibre optic and metallic Ethernet SFP modules are suppor-
ted. For optical both single and dual mode fibre optics
Ethernet modules (= 2 or 1 fibres) can be used. CSFP
modules are not supported. RACOM offers all mentioned
types of SFP and SFP+ modules, tested to be RAy com-
patible as a standard accessory10.
The SFP/SFP+ status LED is located just next to the slot.
It is controlled the SFP/SFP+ module and its function is
specific for each such a module. The typical behavior is
an indication the received signal from the fibre optic or
metallic link to be within operational range.
Note
It is strongly recommended to use a high quality SFP/SFP+ module with industry temperature
range. All SFP/SFP+ modules listed in Accessories11 are thoroughly tested by RACOM and
are guaranteed to function with RAy units. It is possible to use any other SFP/SFP+ module
