COM Port Pinout Assignments

Matrix DFE-Platinum Series Module Installation Guide A-3

 provides the input/output specifications for each XFP version as specified in the IEEE 

802.3ae‐2002 standard.

The following XFP specifications in 

 meet or exceed the IEEE 802.3ae‐2002 standard.

The COM port is a serial communications port for local access to Local Management. Refer to 

 for the COM port pin assignments.

1. The limiting factor is saturation of the receiver by the transmitter. When presented with a signal at a strength

above the saturation point, the receiver cannot distinguish between pulses, though no hardware damage
occurs.
