It is safe to swap the cables to the correct RS232 port. The RS232 cable is used to monitor the SPS status.
I get the fowwoing warning after upgrading diks and adding a new rack to existing DMX-3:  The following errors occurred in Battery Test:-xxx - SPS 3B in Disks Bay 2B (AC121xxx)     - CABLE_NOT_OK xxx - SPS 4A in Disks Bay 2B (AC121xxx)     - CABLE_NOT_OK   I checked SPS physically and found that the ethernet cables of the two SPS are connected wrongly with each other, which means SPS 3B cable is connected to where SPS 4A must connect and vise versa.  Now my question is that how can I reseat the cables in their correct position? is it possible to change the cables while SPS are on? or we shall take another safe approach?
