COM Port Pinout Assignments
Matrix DFE-Platinum Series Module Installation Guide A-3
Table 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 Table A ‐ 4 meet or exceed the IEEE 802.3ae ‐ 2002 standard.
COM Port Pinout Assignments
The COM port is a serial communications port for local access to Local Management. Refer to
Table A ‐ 5 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.
