Figure 4-5: RS-232C Connection
Two SCSI ports on the six channel models (ES U16UG4010-62-0030 and ES U16UG4010-65-0030) can be used for capacity expansion to c ascade a RAID system with a JBOD. Connect the SCSI ports on the controller box’s face plate (marked as CH4 and CH5) to ports on a J BOD. No termination setting is necessary, and there is no limitation as to which expansion port should be connected with which po rt on a JBOD. To be able to monitor the status of different JBOD components it is necessary to use a JBOD that can be connect ed to the I2C port on the ES U16U subsystem. See Error! Reference source not found..
