For first time installation, attach the SCSI devices first to ensure the router and its assigned
devices are working properly. You should connect all SCSI devices to the router and
power them on. Then power the router on. After proper operation is established, you can
proceed to connect the FC host and the RS-232 or Ethernet ports.
