Recovery After Power Failure
CAUTION:
To help prevent the loss of system data during power outages, plug the AC power plug into an
Uninterruptible Power Supply (UPS).
To restore the system after an AC power failure:
Figure 28. Synchronized Screens
Allow at least 30 seconds for the Gateway to boot up again after a power
failure. The following power-up initialization sequence occurs:
a. About twenty seconds after applying power to the Gateway, the
POWER
LED
turns on, and the Initializing message displays on the screen a few
seconds later.
b. When the Gateway connects to the network, the Synchronizing screen
displays briefly to indicate that the Gateway is in the process of detecting
and synchronizing with other devices on the network.
c. Once the Gateway has successfully finished synchronizing with the rest
of the system, the Idle screen displays the time, date and the IP Address
as shown in Figure 28.
All devices in the system may power up simultaneously, depending on the
power arrangement of your site. In a large installation, the DHCP server
may take several minutes to respond. This delay may be especially long
after restoration of AC power.
NOTE:
The time and date may not be correct. The time and date
are set using the WEBUI
“Basic Settings” on page 63
.
