Emergency switch module replacement: srv1917 - srv1964 inclusive

We're preparing to replace a switch module for this stack on an emergency basis, as the switch module keeps losing connection with the management module, where the management module then forces a reboot of the switch module. srv1949 through srv1964 inclusive will experience short downtime as the module for these servers is replaced, however all servers srv1917 through srv1964 will experience port flapping as the stack member ring is re-established. We are providing this advance notice so that you may temporarily shift workloads to other nodes as needed. We will update this posting when the switch module replacement work starts.

Work is commencing. We'll post updates here as we have them.

The module has been replaced and configured, and we're monitoring for stability.

We're considering this stable at this time, and closing out the case.
