Description
Topology You should be sure that the topology setting is correct for your configuration. You can set the
topology to:
• LOOP—Use this option for all configurations except when the SM module is connected
to a switch F-port. You must use this option if the internal hubs are enabled.
• .POINT-TO-POINT—Use this option only when you connect the SM module to a switch
F-port. If you change from Loop to Point to Point mode after already establishing a
public loop connection, the switch may ignore subsequent attempts to perform point to
point initialization. To resolve this, see 7.9, ”Host Fibre Channel Problems”, on page 67
Link Speed You can set the speed to: 1 GB or 2 GB. When you change the link speed, the other host
channel on this I/O module changes speed to match.
