MRXI with an EPIM-A, the following requirements must be met:
•
The transceiver or Ethernet Device to which the module will be
connected must meet IEEE 802.3 standards, and/or Ethernet Version

connected must meet IEEE 802.3 standards, and/or Ethernet Version
1.0 or Version 2.0 standards.
•
The Signal Quality Error (SQE) test function on the transceiver must
be disabled if you connect it to a repeater or to an Ethernet Version 1.0
device. In addition, some Version 2.0 equipment does not support the
SQE test. Devices that do not support SQE test interpret the SQE test
pulse as a collision.
