In this configuration the SCSI bus is split, with each of the connectors 
attached to a host.  If a host is disconnected from the enclosure, the 
CSM isolates the disconnected host from the internal storage and 
remaining hosts.  This allows a host to be taken offline without data 
disruption to the other hosts.  For left side CSM, the Bus A LED is on for 
top connector and Bus B LED is on for bottom connector.  For right side 
CSM, the Bus B LED is on for top connector and Bus A LED is on for 
bottom connector.  The ES LED is on for both CSM’s.
Note:  For information on the I/O module LED, see page 20.
