Disk I/O Card
Also located on the Disk I/O card is a jumper, (JP3), which allows the enclosure’s
internal hubs to be configured for a split-bus mode of operation. The NexStor
4200F Series Storage System only supports “single-bus” mode.
NOTE:
The jumpers JP1 and JP2 are unique for a specific model controller. They
are not applicable to this model and therefore both jumpers should be
installed in the offset position or installed on one pin only.
NOTE: The Disk I/O cards are universal and can be interchanged.
Host I/O Card
The Host I/O card provides the Fibre Channel connectivity from the host
computer(s) to the Fibre Channel RAID Controller host ports. This hot swappable
card is designed to support NCITS T11 Fibre Channel compliant devices at speeds
of 1.0625 Gb per sec or 2.125 Gb per sec. Each card has two SFP cages that
house optical or copper SFP transceivers and they are labeled “H0” and “H1.”
The Host I/O cards are installed at the rear of the enclosure, above the RAID
Controller slots. The right Host I/O card provides connectivity to host channel 0
of both RAID Controllers, and the left card connectivity to host channel 1 of both
RAID Controllers.
