Switch Protocol Error Messages

These error messages indicate errors in communication between SWCI and the

attached switch module. A poor serial connection between the server and the switch

module or an incompatibility between SWCI and the SCC firmware can be the source

of these errors.

Cause. A response message was received from the SCC, but the length of the

message was shorter than the minimum expected response message size.

Effect. SWCI does not work properly.

Recovery. Do the following:

1. Check the configuration of the switch module device and reconfigure if necessary.

2. Check the version of SWCI installed.

3. Power the switch module device off then back on again.

Cause. A response message received from the SCC did not start with an ASCII STX

character (required to indicate the start of any command/response message).

Effect. SWCI does not work properly.

Recovery. Do the following:

1. Check the configuration of the switch module device and reconfigure if necessary.

2. Check the version of SWCI installed.

3. Power the switch module device off then back on again.

Cause. The message length field in a response message received from the SCC was

not a valid numeric value.

Effect. SWCI does not work properly.

***PROTOCOL ERROR*** SCC response message: length too short.

***PROTOCOL ERROR*** SCC response message: frame error.

***PROTOCOL ERROR*** SCC response message: invalid length

field.
