Success.
Network Setup:
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
:
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 Ports needing at least own and free IP
addresses- otherwise the Switch or the receivers (i.e. IPTV STB's) cannot locate the source of the
streams.
Note: For the GBE 1 and GBE 2 ports a security mechanism is installed to avoid setting
them in the same IP-range like you have done for the NMS- port.
On GbE 1 the Gateway can be changed. GbE 2 would follow it automatically:
