TRANSCEIVER Messages

Error Message TRANSCEIVER-3-LAYER_CHANGE_ERROR: Error changing layer for port [char]
Explanation
the layer for this port.
Recommended Action
Error Message C4K_TRANSCEIVERMAN-3-BADSEEPROM: Port [char]: Transceiver's seeprom is
bad, try reinserting: vendor: [char], p/n: [char], s/n: [char]
Explanation
message, and the read of the serial EEPROM's contents succeeded, but the contents are not valid
(perhaps there was a bad checksum). The message tells the vendor, part number and serial number
it read from the transceiver's serial EEPROM. This event could possibly happen because the
transceiver is not seated correctly.
Recommended Action
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.
