I do not think would be your suppervisor card, read bellow. As for the compact flash try reseating it.

1. %C4K_TRANSCEIVERMAN-3-SEEPROMREADFAILED: Failed to read transceiver serial eeprom on port [char], try reinserting

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.
