Software Upgrade Procedure

Refer “Updating the software version and

using CNUT” in the

PTP 450 Configuration

and User Guide

Resetting to Factory Defaults (2

options)

1. On the radio GUI, navigate to

Configuration, Unit Settings and

select Set to Factory Defaults

2. On the radio GUI, navigate to

Configuration, Unit Settings and

enable and save option Set to Factory

Defaults Upon Default Plug

Detection. When the unit is powered

on with a default/override plug (see

section “Acquiring the Override Plug”

in the

PTP 450 Configuration and User

Guide

) the radio is returned to its

factory default settings.

pmp-0815 (August 2015)

Safety and regulatory information

This section describes important safety and regulatory guidelines that must be

observed by personnel installing or operating PTP 450 equipment.

Important safety information

To prevent loss of life or physical injury, observe the safety guidelines

in this section.

Power lines

Exercise extreme care when working near power lines.

Working at heights

Exercise extreme care when working at heights.

Grounding and protective earth

PTP 450 units must be properly grounded to protect against lightning. It is the

user’s responsibility to install the equipment in accordance with national

regulations. In the USA, follow Section 810 of the

National Electric Code,

ANSI/NFPA No.70-1984

(USA). In Canada, follow Section 54 of the

Canadian

Electrical Code

. These codes describe correct installation procedures for

grounding the outdoor unit, mast, lead-in wire and discharge unit, size of

grounding conductors and connection requirements for grounding electrodes.

Other regulations may apply in different countries and therefore it is

recommended that installation of the outdoor unit be contracted to a

professional installer.

Powering down before servicing

Always power down and unplug the equipment before servicing.

Primary disconnect device

The BHM or BHS unit’s power supply is the primary disconnect device.

External cables

Safety may be compromised if outdoor rated cables are not used in connections

for those exposed to the outdoor environment.

PTP 450 Configuration and User Guide

pmp-0815 (August 2015)

RF exposure near the antenna

Radio frequency (RF) fields are present close to the antenna when the

transmitter is on. Always turn off the power to the PTP 450 unit before

undertaking maintenance activities in front of the antenna.

Minimum separation distances

Install the BHM or BHS so as to provide and maintain the minimum separation

distances from people.

Important regulatory information

The PTP 450 product is certified as an unlicensed device in frequency bands

where it is not allowed to cause interference to licensed services (called primary

users of the bands).

Radar avoidance

In countries where radar systems are the primary band users, the regulators

have mandated special requirements to protect these systems from interference

caused by unlicensed devices. Unlicensed devices must detect and avoid co-

channel operation with radar systems.

Installers and users must meet all local regulatory requirements for radar

detection. To meet these requirements, users must set the correct region code

during commissioning of the PTP 450. If this is not done, installers and users

may be liable to civil and criminal penalties.

Contact the Cambium helpdesk if more guidance is required.

USA and Canada specific information

The USA Federal Communications Commission (FCC) has asked manufacturers

to implement special features to prevent interference to radar systems that

operate in the 5250-5350 and 5470-5725 MHz bands. These features must be

implemented in all products able to operate outdoors in the UNII band. The use

of the 5600 –5650 MHz band is prohibited, even with detect-and-avoid

functionality implemented.

Manufacturers must ensure that such radio products cannot be configured to

operate outside of FCC rules; specifically it must not be possible to disable or

modify the radar protection functions that have been demonstrated to the FCC.

In order to comply with these FCC requirements, Cambium supplies variants of

the PTP 450 for operation in the USA or Canada. These variants are only

allowed to operate with region codes that comply with FCC/IC rule.
