26 Field Replacement for an ECN 7000 Series Device
Overview
The ECN 7000 Series of products is designed to allow you to easily replace an
ECN unit in the field after installation. For ECN units with the backup battery
option, you can also easily replace the battery in the field.
Although an ECN is designed for a 10 year operational life, because an ECN is
typically installed in a location that exposes it to weather and other hazards, you
might need to replace ECN units from time to time. In addition, you might want
to replace a working unit with one that includes additional or different expansion
cards to provide additional services for your customers.
Because the ECN’s cover is not designed to be removed in the field (the cover is
secured with one-way screws), you generally cannot perform in-field service for
an ECN. If an ECN becomes non-operational, you should replace it in the field
with a similarly equipped model to maintain operational service for your
customers. You can return the non-operational ECN to your service center for
maintenance; see the
Edge Control Node 7000 Series Hardware Guide for
additional information about performing service.
Replacing a Pole-Mounted ECN
Important: Before replacing an ECN in the field, visually inspect the unit and its
surroundings to ensure that the unit is not damaged and that it is safe to handle.
You do not need to reinstall the Pole Mounting Bracket to replace an ECN unit.
To remove a pole-mounted ECN:
1. If possible, use the ECoS system software to shut down the unit
remotely, before beginning field replacement.
2. Remove all network connections from the bottom of the unit.
3. Remove the power connection from the unit.
4. Remove the screws at the bottom of the unit. These screws will remain
attached to the ECN.
5. Lift the ECN from the Pole Mounting Bracket.
6. Attach a rope to the ECN carry loop to safely transport it to the ground.
To install a replacement pole-mounted ECN:
1. Attach the ECN to the Pole Mounting Bracket, as described in

ECN to Pole Mounting Bracket
on page 6.
2. Secure the ECN to the Pole Mounting Bracket using the screws at the
bottom of the unit, as described in
