investment, as the quality of mains power may have a direct impact on the device operation,
performance and/or reliability. Many users will deploy an Uninterruptible Power Source (UPS)
or other form of battery-backed system, to protect against brown-out and black-out conditions, as
well as to condition the power being presented to the adapter.
It is also important to evaluate the opportunity for lightning or other similar surges to become
present on the powering system, including the ability for surges to couple to the power wiring
system. If an evaluation indicates that there is a potential likelihood for these conditions to occur,
additional surge protection may be recommended for the input power wiring, especially for the
CAT5 cable running from the injector to the radio.
The above statement is similarly true for every wired connection to the device. While the
configuration for surge suppression or line conditioning is of a different type for each kind of
signal interface, the opportunity for damage to the device, loss of communications and property
can be significant. In some cases, there can also be a risk to human life by not protecting against
lightning entering a building through wiring or improper grounding. If you do not have
experience in this type of installation practice, it is strongly suggested that a qualified electrician
and/or telecoms professional is consulted during the installation of the equipment and wiring.
4.2.3 DC Power
The injector accepts direct DC power within the voltage specifications stated (48 Volts, nominal)
and with enough current delivery capacity, also per the specifications stated. Using the proper
DC connector and polarity (as shown on the injector), DC power may be directly connected to
the injector. There are different system grounding considerations depending on the nature of the
DC supply grounding, and your qualified electrician or telecoms professional should be
consulted on the proper wiring and grounding process. Often, the injector housing should be
properly grounded, and the DC source can be floating.
4.2.4 Reset to Critical Factory Settings
If necessary, the radio terminal may be reset to critical factory settings. This may be necessary if
the IP address and/or passwords for the system are not known. All other configurations are left at
their current settings. If a complete default factory configuration is desired, the Default
Configuration File may be loaded into the system, as described in sections 5.10 and 5.11.
The following parameters will be configured after a reset to critical factory settings:
• IP Address = 10.0.0.1
• IP Mask = 255.0.0.0
• IP Gateway = 0.0.0.0
• Administration password = admin
• User password = user
• Endpoint Identifier = Radio B (unless temporary hardware configuration key is
installed)
To perform a reset to critical factory settings:
