Signal Margin
Direct Communication Devices: The amount that the signal
is greater than the noise level at the device in decibels (dB).
Proxies: The amount that the signal is greater than the noise
level at the hop in decibels (dB).
Failure History Provides a historical list of the 45-minutes intervals since the
SmartServer was rebooted in which a device failure (if any)
was reported.
For example, if failures are recorded for the device on
Monday at 14:30, Tuesday at 15:00, Wednesday at 16:00, and
Saturday at 16:15, this property would display the following
text:
Failure 14:15-15:00
Failure 15:45-16:30
The device failure history is cleared when a device has no
failures during a 7-day period.
Last Time
Reached
Displays the time at which the device last responded to a
network message.
Note: The number of proxies displayed in this dialog might differ
from the number shown in the Power Line Repeating Analysis Web
page as the SmartServer updates cached data. To view an updated
list of available proxies in this dialog, close this dialog, click Refresh
in the Power Line Repeating Analysis Web page, right-click the
device, and then select Show Available Proxies in the shortcut menu.
d. You can click Refresh to get the latest cached signal strength and
signal margin measurements.

page.
Adding Devices
After you install a power line repeating network, you can use the SmartServer to
add new devices to the network. The process for adding new devices to an
existing network is the same as initially installing the network. See
Manually
Installing a Street Lighting Network
on page 48 for more information about
installing devices with the SmartServer.
When you add the device to the network, the SmartServer attempts to
commission the new device. The commissioning succeeds if the SmartServer can
communicate with the device either directly or though a repeating chain.
Upgrading Devices
You can use the SmartServer to upgrade a Neuron-hosted device that has
writeable application memory (EEPROM or flash). An upgrade might be needed
to improve the device’s capabilities or to repair a damaged device application.
You can upgrade devices one at a time, or you can perform a batch upgrade.
