In case of the usage of an Optical Pass Through Module, it is necessary to
change the transfer rate that is set, per default, to Auto Negotiation on the 4 GB
host bus adapter to a fixed value of 2 GB. The Optical Pass Through Module can
only handle transfer rates up to 2 GB. Auto Negotiation will not work with 4 GB
host bus adapters. To change the transfer rate, verify the current settings of the
HBA first. Use the command show-settings as shown in Example A-10 on
page 514.
Example: A-10 Settings of the QLogic HBA

The show-settings command also shows the firmware and FCode versions as
well as node and port names. Data rate is shown as well. The adapter is currently
configured for Auto Negotiation. To change the data rate to a fixed data rate of 2
Gb, use the command set-data-rate as shown in Example A-11.
Example: A-11 Change the data rate of a QLogic HBA

Example A-11 shows that the data rate is changed from auto negotiation to a
fixed value of 2 Gb. Enter the number in front of the value that you want defined
here. The example uses 1. The changed value will be returned.
