We assume that the user is familiar with IP settings and already knows his own system to connect the
unit to. If you use the Output Streaming feature: We recommend using 2 separate Switches! At least a
100BaseT for the Management NMS RJ45 port and a second one with Gigabit Ethernet
10/100/1000BaseT with at least Layer 2+ with IGMP V2 features. Otherwise you might flood your
IP-Streaming network with unnecessary Data, which might overload connected IPTV STB's because they
almost have only 100BaseT capacity (Never ones use 1GbE ports) but too many inputs into a STB can
result in side effects. If you need to select a Switch, we recommend HP Procurve 2530 24G or 48G which
are cost effective, easy to configure, can be trunked and supporting IGMP V2. If the switch needs routing
functions, the bigger brother of this series might be the right choice.
Because to not accidently put DATA and NMS port in the same sub-network the data – port setting does
not allow this by default. Usually the DATA GbE Port needs an IP address- otherwise the Switch or the
receivers (i.e. IPTV STB's) cannot locate the source of the streams.
APPLY and better to
Safe & restore, Backup & load configs:
We highly recommend to safe the configuration to be able to restore it at all time just in case the unit
was accidently w/o power or any other interruptions happened.
This method is only temporary so we recommend to use the Backup and Load function instead:
