Important Notes
•For the warranty to be honored, install the unit in accordance with the instructions in this
manual.
•Any changes or modifications of equipment not expressly approved by the manufacturer could
void the user’s authority to operate the equipment and the warranty for such equipment.
•PTP 820G is intended for installation in a restricted access location.
•PTP 820G must be installed and permanently connected to protective earth by qualified service
personnel in accordance with applicable national electrical codes.
General Equipment Precautions
Caution
To avoid malfunctioning or personnel injuries, equipment or accessories/kits/plug-in
unit installation, requires qualified and trained personnel. Changes or modifications
not expressly approved by Cambium Networks can void user's authority to operate
the equipment.
Caution
Where special cables, shields, adapters and grounding kits are supplied or described
in this manual, these items must be used to comply with the FCC regulations.
Caution
Use of controls, adjustments, or performing procedures other than those specified
herein, may result in hazardous radiation exposure.
Caution
When working with a PTP 820G, note the following risk of electric shock and energy
hazard:
Disconnecting one power supply disconnects only one power supply module. To
isolate the unit completely, disconnect all power supplies.
Caution
Machine noise information order: 3. GPSGV, the highest sound pressure level
amounts to 70 dB (A) or less, in accordance with ISO EN 7779.
Antistatic
Static electricity may cause body harm, as well as harm to electronic components
inside the device. Anyone responsible for the installation or maintenance of the PTP
820G must use an ESD Wrist Strap. ESD protection measures must be observed when
touching the unit. To prevent damage, before touching components inside the device,
all electrostatic must be discharged from both personnel and tools.

Caution
In Norway and Sweden:
Equipment connected to the protective earthing of the building installation through
the mains connection or through other equipment with a connection to protective
earthing –and to a cable distribution system using coaxial cable, may in some
circumstances create a fire hazard. Connection to a cable distribution system has
therefore to be provided through a device providing electrical isolation below a certain
frequency range (galvanic isolator, see EN 60728-11).
Utstyr som er koplet til beskyttelsesjord via nettplugg og/eller via annet jordtilkoplet
utstyr –og er tilkoplet et kabel-TV nett, kan forårsake brannfare. For å unngå dette skal
det ved tilkopling av utstyret til kabel-TV nettet installeres en galvanisk isolator
mellom utstyret og kabel- TV nettet.
Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via
annan utrustning och samtidigt är kopplad till kabel-TV nät kan i vissa fall medfőra risk
főr brand. Főr att undvika detta skall vid anslutning av utrustningen till kabel-TV nät
galvanisk isolator finnas mellan utrustningen och kabel-TV nätet.

Chapter 2: PTP 820G Hardware Description
PTP 820G is a compact unit that fits in a single rack unit, with a passive cooling system that
eliminates the need for fans. A PTP 820G system consists of a PTP 820G indoor unit (IDU) and one
or two radio frequency units (RFUs). A coaxial cable connects the IDU to each RFU, transmits
traffic and management data between the IDU and the RFU, and provides DC -48V power to the
RFU.
A PTP 820G IDU contains six Ethernet interfaces, one or two radio interfaces depending on the
hardware configuration, and optionally a 16 x E1/DS1 interface.
The IDU also includes two FE management interfaces, a DB9 dry contact external alarms interface,
an RJ-45 synchronization interface, and an RJ-45 terminal console interface for connection to a
local craft terminal.
PTP 820G receives an external supply of -48V, with an optional second power interface for power
redundancy.
The following hardware assembly options are available for the PTP 820G IDU:
•One or two radio interfaces
•With or without 16 x E1/DS1 interfaces

Ethernet Traffic Interfaces
phn-3967_005v000
Page 2-2
Ethernet Traffic Interfaces
The front panel of the PTP 820G contains four electrical and two optical GE Ethernet traffic
interfaces:
•2 x GE dual mode electrical or cascading interfaces (RJ-45) –GbE1/CS1, GbE2/CS2
•2 x GE electrical interfaces (RJ-45) –GbE3, GbE4
•2 x GE optical interfaces (SFP) –SFP5, SFP6
Ethernet Traffic Interface LEDs
Each electrical interface has the following LEDs:
•Port Status LED –Located on the upper left of each interface. Indicates the link status of the
interface, as follows:
oOff –The interface is shut down or the signal is lost.
oGreen –The interface is enabled and the link is operational.
oBlinking Green –The interface is transmitting and/or receiving traffic.
•Port Rate LED –Located on the upper right of each interface. Indicates the speed of the
interface, as follows:
oOff –100Base-TX
oGreen –1000Base-T
oBlinking Green –10Base-T
Figure 2 Electrical GE Interface LEDs
Each optical interface has the following LED:
•Port Status LED –A Port Status LED is located on the lower left of SFP5 and the lower right of
SFP6. Each LED indicates the link status of the interface, as follows:
oOff –The interface is shut down or the signal is lost.
oGreen –The interface is enabled and the link is operational.
oBlinking Green –The interface is transmitting and/or receiving traffic.
