1 Safety instructions
Do not open the casing. Warranty shall be void if the warranty seal has been
tampered with.
Don't use or install the device in an explosive atmosphere!
Don't touch any contacts with metallic or pointed items.
This device has no power switch. Please disconnect the power before any
operational work.
In case of any damage to the device, it must not be put into operation.
Do not install the device during a thunderstorm!
Protect the device from heat sources and direct sunlight.
Protect the device from aggressive fluids and vapors.
The router emits electromagnetic waves. To prevent other devices from
being disturbed and to protect other people, install the router only as
described in this document and make sure to comply with safety distances.
Unauthorized persons must not get nearer than 60cm to the
GSM/UMTS/LTE antennas.
Unauthorized persons must not get nearer than 7cm to the WLAN
antennas.
Depending on the router type, the antenna and configured networks the
safety distances may be smaller. Use the calculations in the Annex to
calculate the minimum safety distance of your router.
Remove the power connector before performing any maintenance or
cleaning work near to the antennas or directly at the router.
Read these safety instructions before handling or installing
the device.
Risk of burns! The device can operate in surroundings of
more than 70 °C, so the surface can get very hot. Install the
router inaccessible for unauthorized personnel. Before
touching the router, remove the power supply and wait for
10 minutes for the router to cool down or wear protective
gloves.

The router type can be identified by the serial number of the router. The type is coded
into the first 5 characters of the serial number.

There are 2 variants of the router casing:
Routers without xDSL modem are delivered with a 44.5mm high 2 piece
aluminum die cast casing.
Routers with xDSL modem are delivered with an 80.5mm high 3 piece
aluminum die cast casing.
If not otherwise indicated, the following document will be written
based on the xDSL variant of the casing, as the smaller casing
mainly contains a subset of the xDSL router’s components.

3 Hardware
3.1 Installation
The Garderos R-7700 has an integrated DIN rail mounting clip. Mount the router at a
DIN rail as shown in the following drawing. The DIN rail clip has a spring that will
automatically close the clip when the router fits to the rail.
For unmounting the router, use a screw driver with a long metal point and open the
DIN rail clip as shown in the following drawing. Then push the router up to remove it
from the DIN rail.

3.2 Grounding
Grounding is not required for router operation but it improves the EMI characteristics
and is mandatory to comply with the standard IEC 61850-3. For grounding crimp a
1.5mm² ground cable to the grounding lug that is included in the router delivery. Fix
the grounding cable with the washer between the M4 screw and the cable lug to any
of the screw holes in router case. See the following picture for an example:
3.3 Status LEDs
The Garderos R-7700 has up to 10 LEDs on the front, showing its operational status.
All LEDs, except from the Ethernet LEDs that are integrated into the RJ-45 Ethernet
sockets, are clearly marked on the casing:
P (green) Shows the status of the router’s power supply and is lit
during the entire period of operation.

© 2019 Garderos GmbH 8/23
S (green) Shows the current state of the router operating system.
The LED blinks during fetching and executing the router
configuration and is permanently lit when the configuration
of the device has been completed.
W1 (green) Depending on the type of the WWAN link this LED signals
the state of the link. The LED is off when no WWAN
connection is active and is lit while at least 1 WWAN
connection is active.
W2 (green) Is lit when the integrated WLAN interface is active.
Sync (yellow) Shows the xDSL modem synchronization status. The LED
is off after boot, blinks when the modem tries to
synchronize and is lit while the modem is synchronized.
Power (green) Shows the power state of the xDSL modem. The LED is lit
during the entire period of operation.
Eth link (green) Is lit when an Ethernet link was detected.
Eth activity (orange) Blinks during Ethernet activity.
In normal operation mode the LEDs Power, Pand Sare on, as well as the green
LEDs of all connected Ethernet ports.
3.4 Connectors
Depending on the type, the Garderos R-7700 routers have different connectors on
the front. All possible connectors are described below; the image shows the front
panel of an R-7731 as an example. The R-7700 routers have 2 SIM card slots on the
back:

3.4.4 Antenna connectors
Depending on the router type the antenna connectors M1, A1, M2, A2 and M3 are
used for different antenna connections, e.g. a 3G or a WiFi card. The connectors are
always SMA female when being used for 2G/3G/4G/CDMA radio networks and RP-
SMA female when being used for WiFi. Login to the router and use the command:
R7700# show hardware connector
to show the assignment of the antenna connectors.
3.4.5 Optional RS-232 connector
The R-7700 series routers can be equipped with an additional fully allocated DSUB-9
connector for RS-232. This must be ordered as a special option and will result in less
antenna connectors.
