Perle Systems C-4GPT-DSFP, CM-4GPT-DSFP manual Fiber Fault Alert Switch, Rate Select Switch

Fiber Fault Alert (Switch 2)

Switch Position	Mode
Up (default)	Enabled
Down	Disabled

Enabled: If the media converter module detects a loss of fiber signal on its fiber receiver, it will disable its fiber transmitter on the same SFP. This, in effect, notifies the fiber link partner that an error condition exists on the fiber connection.

Disabled: The Protocol Transparent Media Converter module will not monitor for Fiber Fault.

Note: If 2 media converters are connected to each other, FFA should not be enabled on both since this could create a “dead- lock” state.

Rate Select (Switch 3)

Switch Position	Mode
Up (default)	High Speed
Down	Low Speed

High Speed – When a multi-rated SFP is inserted, it is enabled for its higher speed of operation.

Low Speed – When a multi-rated SFP is inserted, it is enabled for its slower speed of operation.
