Host I/O Card - NexStor 4900F Series User Manual

Also located on the Disk I/O card is a jumper, (JP3), which allows the enclosure's
internal hubs to be configured for split-bus operations. The NexStor 4900F Series
Storage System only supports "single-bus" mode. The setting should be offset.
The jumpers JP1 and JP2 provide hardware failure detect signals. Both jumpers
should be installed in the on position (placed on both pins).
NOTE: The Disk I/O cards are universal and can be interchanged.

Host I/O Card

The Host I/O card provides the fibre connectivity from the host computer(s) to
the Fibre Channel RAID controller 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 controller's port
0 (C0P0 and C1P0) of both RAID controllers, and the left card provides
connectivity to controller's port 1 (C0P1 and C1P1) of both RAID controllers.
LEDs on the card's face plate will illuminate to indicate 2 Gb mode, host link
status, and activity.
