The front panel includes the following features:
•
A power LED located below the part number
•
Eight mini-RJ21 connectors, each supporting six 10/100/1000 Mbps Ethernet ports
The eight mini-RJ21 connectors support six 1 Gbps Ethernet ports each. You can connect a patch
panel with a mini-RJ21 connector to a mini-RJ21 connector on the interface module. The patch
panel provides RJ45 connectors. You can also use a cable with a mini-RJ21 connector on one end
that connects to the mini-RJ21 connector on the interface module. The other end of the cable splits
into six cables with RJ45 connectors on each cable.
The NI-MLX-1Gx48-T-A module ships with two cable cinches. Each cable cinch consists of a plastic
part and a velcro strap. For instructions on using the cable cinches, see
