Connect the SAS HBA cards in the second Host PC to the other table-routed
ports (CN2) on the I/O modules of the first J300s unit.

Set Up Serial Cable Connections

The RS-232 Serial connection enables your PC to monitor and control the J300s
unit through the Command Line Interface (CLI).
Figure 13. A serial connector is located on the I/O module
Connect a null-modem cable (supplied with the J300s unit) to the DB-9 connector
on the I/O module. If your J300s unit has two I/O modules, connect the null-
modem cable to the I/O module on the left.
Connect the other end of the cable to the DB-9 COM port on the Host PC.
If your PC has a second DB-9 COM port and your J300s unit has two I/O
modules, you can connect a second null-modem cable to the DB-9 connector on
the I/O module on the right.
See "Set Up Data Cable Connections" on page 15 for an explanation of which I/O
module is the default primary. To verify which I/O module is the default primary,
