few minutes to read these installation instructions in order to obtain the maximum performance from
this product.
FUNCTIONAL DESCRIPTION
The MXR4-1000TX series combines four copper Ethernet ports. MXR4-1000TX units allow

The MXR4-1000TX series is configured to auto negotiate the data ports to either 10Base-T, 100Base-
TX, or 1000Base-TX Ethernet data at full or half duplex. The auto negotiate feature also selects the

This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation.
The detachable terminal block, RJ45 Ethernet data connector, and LED indicators provide for easy
installation and monitoring of data and dc power. The MXR4-1000TX is designed for rack mounting in
the MXRC-1 subrack. For mounting as a modular stand alone unit see the MX4 series.
