Appendix A: Graceful Startup/Shutdown Procedure

Instruction Manual
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 the 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.
IMPORTANT:
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.
5.
V2 Master Server
-
The master server must be fully started and online. Check that the Vision
2
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
2
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 the "unable to load web page" message appears on screen, 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.
Troubleshooting
In the case that this procedure is followed, but does not return the system to functionality, there are several steps which may be
performed to verify which portion(s) of the system is not operating properly. For purposes of this document, these steps are
bulleted, with more detailed information referenced.
No TV signal on screen
Verify that the display is connected to power and to the STB-04.
Verify that the display is powered on.
Verify that the STB-04 is connected to power, network, and to the video display.
Verify that the STB-04 is powered on by checking the red LED on the front of the STB-04
Verify that the STB-04 has network connectivity by checking connectivity and activity lights on the rear of the unit.
Verify that the correct video display input is selected (check video connection from STB-04).
Verify that the STB-04 has a proper IP address and that the default browser page is configured.
No TV signal from Transmitter
Verify that network switch is operational, and that connectivity/activity lights are illuminated and flashing.
Verify that CATV connection/service is functioning, and that transmitters have power, coaxial (RF), and network
connections.
Verify that transmitters are powered on, or that power source (strip/UPS, etc) is working.
Verify that transmitters have active network connections with network activity lights on the NIC illuminated and flashing.
Verify that the transmitter is configured and has a saved channel list (refer to the
AMX TDS Television Distribution System
Operation/Reference Guide
for details on transmitter configuration).
Beyond these simple checks, the configuration of the V2 TDS gateway and the DTV-MA01 may need to be verified. For additional
details, consult the Operation Reference guides for these products, available at www.amx.com, or contact AMX Technical Support.
