VTrak J300s Quick Start Guide
The arrangement requires J300s units with dual I/O modules and Host PCs with
dual SAS HBA cards in each PC.
Connect the SAS HBA cards in the first Host PC to the table-routed ports (CN1)
on the I/O modules of the first J300s unit.
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.
Connect the subtractive-routed port (CN3) on the I/O modules of the first J300s
unit to the table-routed ports (CN1) on the I/O modules of the next J300s unit.
Connect the remaining J300s units in the same manner.
Use a SFF-8470 4X to 4X external SAS cables with thumbscrew connectors.
Step 5: 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 11. A serial connector is located on each 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 left I/O module.
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 "Step 4: Set Up Data Cable Connections" on page 6 for an explanation of
which I/O module is the default primary. To verify which I/O module is the default
primary, see Chapter 3 of the Product Manual .
