Chapter 1 - Getting Started
The following table defines the function of each switch:
Each card contains Port Bypass Circuits (PBC) that allows for hot swapping,
improved signal quality and valid FC signal detection. An onboard Clock
Recovery Units (CRU) is provided to improve the signal quality, determine
whether the input is a valid FC signal, and amplification and jitter removal for
optimum quality signals.
Cabling diagrams are provided in the Installation chapter for each supported
topology. To ensure proper connectivity, failover and failback operations, and
LUN presentation, follow the cabling diagram for your selected topology.
SFP Transceiver
The Host I/O and Disk I/O cards incorporate SFP cages which support optical
hot-swappable Small Form-Factor Pluggable (SFP) transceivers.
The optical SFP transceiver is Class 1 Laser safety compliant and conforms to
Class 1 eye safety standards.

Function
Sets the FC Loop speed to 1 Gb or 2 Gb. An LED on the
card will illuminate to indicate 2 Gb mode. The "up"
position sets 2 Gb mode and the "down" position will set
the loop to 1 Gb mode.
Sets the enclosure for a specific controller model. This
switch must be set to the "up" position for the
"imageRAID" Controller. The "down" position is not
applicable.
This switch is not used.
This switch when enabled, "up" position, provides the
link between the Host I/O card H0 and H1 ports. This
switch should be set to the "down" position when Switch
6 is enabled ('up' position).
This switch is not used.
This switch is enabled (up position) when dual
controllers are installed. It is used to enable automatic
internal hub failover during a controller failure.
This switch is not used.
This switch is not used.
