Edge Control Node 7000 Series Installation Guide 9
Complete the Installation
After the installation is complete, perform the following tasks:
1. Inspect the connection of the ECN to the Pole Mounting Bracket.
2. Inspect the connection of the Pole Mounting Bracket to the utility pole.
3. Inspect the cabling connections to the ECN.
The completed installation should look similar to the views depicted in
Figure 2
on page
7. Note that the figure does not show the cabling connections to the
ECN.
Verifying Successful Installation
Because the ECN has no external lights or displays, it uses an internal audio
buzzer to provide indications of important installation-related states. The
buzzer’s audio frequency is 2.4 kHz (as a 1/2 duty cycle square wave) and outputs
85 to 92 dBA of sound pressure,
2
which should be audible from at least 10 m (30
ft).
Table 1 lists the sound patterns for the audio indicator. The audio indicator
outputs its audio indicator patterns once only.
Table 1. Internal Audio Indicator Sound Patterns
Sound Pattern
On (ms) Off (ms) Repeat
Description
1000 0 1 ECN first starts up
1000 0 1 ECN main processor starts running
1000 500 3 Successful direct WAN connection
1000 500 6 Successful indirect WAN connection
4000 500 2 No WAN connection made
As the table shows, a successful installation should include two 1 second sound
bursts and at least one repeated pattern (1 s on, 0.5 s off) to indicate a successful
network connection. If you receive the repeated pattern (4 s on, 0.5 s off) that
indicates unsuccessful network connection, check the network cable connection
and verify that the network is operational.
After installation is verified successful, use the ECoS Web page interface for the
ECN to verify additional functionality. You might also want to disable the
internal audio indicator so that subsequent resets or power events do not cause
the audio indicator to output its audio indicator patterns.

dBA measures sound pressure levels relative to 20 μPa (rms) at 1 m.
