TRANSCEIVER Messages
Error Message TRANSCEIVER-3-LAYER_CHANGE_ERROR: Error changing layer for port [char]
Explanation
The TRANSCEIVER subsystem encountered an internal software error while changing
the layer for this port.
Recommended Action Contact your technical support representative.
Error Message C4K_TRANSCEIVERMAN-3-BADSEEPROM: Port [char]: Transceiver's seeprom is
bad, try reinserting: vendor: [char], p/n: [char], s/n: [char]
Explanation
A transceiver with a serial EEPROM has been detected in the port referred to in the
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 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.
Error Message C4K_TRANSCEIVERMAN-3-INCOMPATIBLE: Port [char]: New transceiver (speed
[char]) is in compatible with this module
Explanation
The inserted transceiver is an incompatible type for this module. Please check
documentation on supported transceivers for this module. Please make sure the speed of the inserted
transceiver matches with the port speed and it is of a supported type for this module.
Recommended Action Remove this transceiver from the port if it is found to be of incompatible type
for this module.
Error Message C4K_TRANSCEIVERMAN-3-MDIOERROR: Mdio bus error while looking for
changed x2s on port [char]: [char]
Explanation There was an internal communication error when reading transceiver control data.
Recommended Action Remove and re-insert the transceiver. It may not be properly seated.
Error Message C4K_TRANSCEIVERMAN-3-S2WERROR: S2w bus error while looking for changed
transceivers on port [char]: [char]
Explanation
Internal communication error when reading transceiver control data.
Recommended Action Remove and re-insert the transceiver. It may not be properly seated.
