Simplex Mode (NexStor 4911F/4912F/4931F/4932F)
The basic simplex (Stand-Alone) operating mode provides a single enclosure
with a single RAID Controller solution. This mode provides solutions for single or
multiple host environments to achieve a fault-tolerant disk storage solution. It has
provisions for drive channel expansion through daisy-chaining of NexStor 4000F
JBOD enclosures, and/or upgrading to a dual RAID Controller model by adding
an additional controller for duplex operations.
CAUTION:
The bus speed must be set to the same setting between the disk
drives and the Disk I/O card(s), and the host system HBAs (BIOS
setting) and the Host I/O cards. For example, if you are using 2 Gb
drives, the Disk I/O cards must be set to 2 Gb mode. If your host
system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must be set
to 1 Gb mode.
NOTE:
Split-bus mode is not supported when a RAID Controller is installed.
Stand-Alone Dual Port Single Host Configuration

Set the jumper (JP4) on the Disk I/O card to configure the bus speed mode.
Loosen the two captive fastener screws on the Disk I/O card and pull it from
the enclosure using the fastener screws. Locate the jumper JP4 and position it
for the desired speed setting, (installed on one pin only for 2 Gb mode and
on both pins for 1 Gb mode).
