Configuration Cabling
After you place IP gateway cards in your router frame and assign their IP addresses, connect the
Ethernet ports of the IP gateway cards to an Ethernet switch using Ethernet cable. The configu-
ration PC on which you use the browser application must be able to access the subnet used by
the frame sync cards your are configuring.
It is not necessary for all IP gateway cards to be on the same subnet.
It is not necessary for IP gateway cards to be connected unless you are configuring them.
There is no relationship between the network(s) used by the IP gateway cards and the network
used by the router’s control cards.
There is no relationship between the network(s) used by the IP gateway cards for configuration
and the network used by the IP gateway cards for I/O.
Browser Application
There is a browser application built into the IP gateway input card. There is a quite similar
browser application built into the IP gateway output card.
The main purpose, but not the only purpose, of the browser applications is to specify the
mapping of the IP addresses of packetized video streams to the video port numbers of the card.
The configuration of the output card also specifies the destinations of the downstream inputs.
To view or change the configuration of any IP gateway card, enter its IP address in the address
line of your browser (Internet Explorer, Firefox, Chrome, or other).
Background
At present, the mapping of video streams to video ports is relatively fixed and relatively simple.
Fixed Relationships
For the NV8140, NV8144, NV8280, and the upper bays of the NV8576 and NV8576-Plus,
SFP 1 is assigned to video ports 1–3,
SFP 2 is assigned to video ports 4–6,
SFP 3 is assigned to video ports 7 and 8
For the lower bays of the NV8576 and NV8576-Plus, in which cards are installed “upside down,”
the ordering of the SFPs is reversed, to keep SFP 1 at the top. With that ordering, the port assign-
ments are similar to the port assignments for the upper bays.
SFP 1 is assigned to video ports 1–3,
SFP 2 is assigned to video ports 4–6,
SFP 3 is assigned to video ports 7 and 8
In all cases, both upper bays and lower bays, port ordering proceeds from top to bottom.
Because the IP gateway cards are disembedder (input) and embedder cards (output), the actual
video port numbers for the slot in which the IP gateway card resides are determined by the slot.
(For reference, you can refer to the port numbering drawings that you received with the router.)
