your IT department regarding setting DCHP
active or inactive.
3) Use the SNMP Configuration submenu page to
enter up to three destination device addresses.
These are addresses where the SNMP feature
will send trap messages whenever a qualifying
event takes place. Qualifying events include the
following;
A) Down Converter LO Lock Fail
B) UP Converter LO Lock Fail
C) ADC Overflow
D) DAC Overflow
E) General Alarm - over current, over temp,
and oscillation.
4) Setup the SNMP format using the SNMP Con-
figuration submenu page. Items that need to be
configured include Authentication Type, User
Name, Password, and Encryption Type. Consult
with your IT specialist for assistance.
5) Load the SNMP manager software into the des-
tination computer and configure the manager so
that it will be able to receive the SNMP traps.
6) Download MIB files from the Bird Technologies
website (www.birdrf.com) and load the MIB files
into your SNMP manager software. The MIB
files allow the SNMP manager software to sort
out the trap messages into an understandable
message format.
The signal booster supports several SNMP Config-
uration validation checks which help ensure the
configuration is setup in a logical format. The vali-
dation checks include;
A) If encryption is enabled but authentication is not
enabled a popup window will appear stating that
you must enable authentication when encryp-
tion is enabled.
B) If Authentication and/or Encryption is enabled
and a password is entered which is < 8 charac-
ters long an error message will be displayed.
C) If an IP address is entered but a User Name is
not entered a popup warning will appear but the
changes will be submitted.
D) If a User name is entered but an IP address is
not entered a popup warning will appear but the
changes will be submitted.
SNMP MANAGER EXAMPLE
SNMP manager software is designed to provide a
GUI style interface for the user so that traps sent
from the booster can be received and displayed for
viewing. The SNMP manager software chosen and
used by the customer is up to the customers dis-
cretion and as such may not exactly match the
example shown in this discussion. SNMP manager
software packages will need to be properly config-
ured in order to successfully receive messages
from the booster. Refer to the SNMP configuration
setup discussed earlier in this manual and ask your
IT specialists for assistance.
When a qualifying event occurs in the booster a
trap is formulated and sent to the destination com-
puter. A typical trap is shown in Figure 19. In the
example shown the trap messages are shown at
the top of the screen display. Three trap messages
have been received by this manager from a signal
booster. In this particular SNMP manager software
package if a trap message is selected the details of
that message are displayed in the lower portion of
the screen. The details show the raw message as it
was received by the manager while the upper box
shows the message after it has been interpreted by
the MIB files.
Creating an Alarm for Testing Purposes
In the example shown in figure 19 an alarm condi-
tion was generated in the booster in order to create
the trap messages shown. The booster was told to
generate its oscillator clock signals using an exter-
nal reference source but no external source was
connected to the booster. This is a quick and easy
way to create a temporary alarm for testing pur-
poses. This is accomplished via the Link Page dis-
cussed earlier in the manual. Select the ON radio
button labeled EXT 10 MHz Reference then click
the Submit button. Do not connect a signal source
to the external osc port on the control module. This
will cause the downlink and uplink oscillators in the
channel to shutdown and the booster will enter an
alarm condition. Please note that on-air signals will
be interrupted during this time. To clear the alarm
select the OFF radio button then click the Submit
