Operation/Reference Guide

When all systems are down, you can safely proceed without negatively impacting the operation of the IPTV
system. Once complete, the information which follows will provide the recommended startup procedure to
return the system to operation.
Startup/Restart
The order of startup is critical to the proper operation of the IPTV system following a network or power
outage. Several of the system components provide configuration or status details to each other, and the absence
of that information can cause components to malfunction.
A short wait period between powering up each device is recommended to ensure that each has a chance to
initialize before the next, to provide any needed configuration or status data in the proper sequence.
In addition, if the network has been offline during an outage, the first requirement before bringing the IPTV
system back into service is to ensure the network switches are in operation.
If the servers or management appliances come online without network present, they may default to local
loop-back addressing, which would impair or stop necessary services within those devices.
The recommended order for restoration of the system components, and their tasks is:
1. Switch on network switches, routers and any other network infrastructure e.g. DNS servers.
2. Switch on TV Headend RF/Cable/Satellite.
3. DTV-TX03 Transmitters - connect the power cord to the transmitters. Verify power and network
connectivity by looking at the lights on network interface at the rear of the unit.
4. DTV-MA01 TDS Management Appliance - press the power button on the front face until the power and
activity lights illuminate and flash. Verify network connectivity by looking at the indicator lights on
network interface at the rear of the unit.
5. V2 Master Server. Your master server must be fully started and online. Check that the Vision

Server
and VLC Server applications are up and running.
6. Check that all slave servers are up and running. Check that the Vision
2
Server and VLC Server
application are up and running.
7. STB-04 Vision

Set-Top Box - connect the power cord to the Set-top box. Verify power and network
connectivity by looking at the lights on network interface at the rear of the unit.
If you see a message on screen "unable to load web page" then place the unit into standby using the amino
remote control, press STB then the power button, wait a few seconds then press the power button again
and ensure that the correct web page is loaded.
It may not be necessary to power down every Amino throughout the facility in the
event of a planned network or power outage, but it is a recommended practice. When
network and power are restored, it may be necessary to select a program to be
played on each Amino. This can be accomplished by using the hand-held Amino
remote, or through the Vision

UI in the Manage System > Manage STB screen
IMPORTANT! - Restarting the DTV-MA01 causes it to beacon out to all attached
Transmitters. These units will then respond back to the DTV-MA01 and will
re-create the list of units found, refreshing the list of channels and re-sending
requests to transmitters to stream the requested channels.
