16-361 IOT/ESS Communication Failure 1 (ExtPrt)
Incorrect parameter set
Initial Actions
Switch the power off, then on. If the problem continues, check the connections at the MCU
PWB and the I/F PWB. Check that the DDI cables from the Network Controller (NC) to the IOT
are secured and are free from damage.
Procedure
Switch off the power. Disconnect the DDI cables and the network cable from the NC to the IOT.
Switch on the power. The fault, or another DFE communications fault (16-361 through 16-
390) is still present.
YN
Reload DFE software. If the problem persists, Switch the DDI cables from the NC to the
IOT (switch both ends). If the problem changes, replace the cables.
If the problem continues, verify that the NC is functioning correctly. Refer to the NC ser-
vice documentation.
