Condition 4 – SFP not installed
• Unlike the primary (OPT - IN 1) indicator, this indicator will be extinguished when the
SFP used in the secondary (bottom) dock of the dual SFP cage is either faulty or not
installed correctly. This is to avoid any false indication when a Thunder System is
purchased without the redundant optical backup SFP installed.
Link
Indicates that proper communication has been established with the processing electronics
of the remote Thunder Chassis.
• Illuminates solid red when there is either no link, or excessive errors in the fiber optic
cable path are preventing proper communication with the remote Thunder Chassis.
• Illuminates solid green when error-free communication has been established with the
remote Thunder Chassis.
Data

mounted DB-15HD connector.
