This page provides a graphical representation of controller host port status and port details. 2. Review the graphical representation of host port status. ■ Green - Host link is up ■ Red - Host link is down ■ White - Port is unused and does not contain an SFP An indication of link down can be caused by one or more of the following conditions: ■ A faulty HBA in the host ■ A faulty Fibre Channel cable ■ A faulty SFP ■ A faulty port in the host interface module ■ A disconnected cable 3.
