Galaxy A16F-R2422 Installation and Hardware Reference Manual
When the DIP switch 5 is manually switched to the up and 6 to the down
position for FC-AL loop running at 4Gbps speed, firmware that is running
in the subsystem must also be adjusted accordingly. You may access the
firmware by the LCD in front of the subsystem, RS-232C hyper terminal
screen, telnet and RAIDwatch management program. Without changing
the Fibre loop speed options in firmware may eventually slow down the
running speed and cause system error.
4.4 Sample Topologies
Depending on the internal hub activation by the DIP switch, the FC ports
can be used to connect the A16F-R2422 to the hosts, external devices and/or
daisy chain other A16F-R2422 subsystems. The subsystem will
automatically validate the dual-loop configuration, and the RAID controller
will activate the enclosure monitoring service accordingly.
Rather you are going to connect the A16F-R2422 to hosts, external
devices or daisy chain other subsystems, be sure to have SFP transceivers
and Fibre cables ready. You may purchase the SFP transceivers and
Fibre cables from your subsystem vendor. See Appendix C for the
available accessories list.
4.4.1 Direct Connection to Single Host
As shown in Figure 4-3, one (1) A16F-R2422 is directly connected to
single host computer. Multiple logical drives or multiple partitions can be
created and made available separately through different ID/LUN's on the
host ports.
Configuration:
Connect one of the left FC port on the host connection module to single host
computer. This topology does not support controller redundancy.
