Attaching Media

Use multi-mode fiber optic cable with short-wave SFP+ transceiver, use singe-mode fiber optic cable

with long-wave SFP+ transceiver, that adheres to the following specifications:

Note: The HBA will not allow normal data transmission on an optical link unless it is

connected to another similar or compatible laser product (that is, multimode to

multimode.)

Note: The HBA will not automatically downgrade to the required FC speed based on cable

length. You must downgrade the speed with the appropriate utility or link errors may

occur.
