UFAST_MCAST_SW Messages
Error Message C4K_TRANSCEIVERMAN-3-SEEPROMREADFAILED: Failed to read transceiver
serial eeprom on port [char], try reinserting
Explanation
A transceiver with a serial EEPROM has been detected in the port referred to in the
message, but the read of the serial EEPROM's contents failed. It is necessary to read the serial
EEPROM to determine what sort of transceiver it is. Sometimes the read fails because the
transceiver is not seated correctly.
Recommended Action Try removing and reinserting the transceiver. If this message still appears after
that, try the transceiver in another port, to verify that the transceiver is bad, and not the port. If the
transceiver fails in another port, return the transceiver, as the transceiver must be reprogrammed for
it to work. If the transceiver succeeds in other ports, but not the original port, that implies that the
original port is bad, not the transceiver, and the module needs to be returned, to fix the port. As a
further test of the port, other transceivers could be tried in the suspected bad port. If these other
transceivers also fail in that port, it is very likely that the port is bad.
