LLCF is enabled when the LLCF switch is in the ON position. The fiber-to- fiber repeater is shipped with LLCF disabled. On the fiber-to-fiber convert- ers (2151-AD-, 2125-xx- and 2135-34-01), LLCF is always enabled and cannot be disabled. Sliding the LLCF switch up and down on these models has no effect. LLCF is not applicable to the copper-to-fiber repeaters. For more information, refer to Link Loss Carry Forward in the User Guide section of this manual.
Copper Loss Carry Forward (CLCF) Switch
The copper-to-fiber repeater provides Copper Loss Carry Forward to assist in identifying a lost copper link. When CLCF is enabled and the repeater loses link on its copper port, the card prevents its fiber port from transmit- ting link pulses. CLCF has no effect on the copper port, which continually transmits link pulses, even if the fiber port loses link.
CLCF is enabled when the CLCF switch is in the ON position (down). The unit is shipped with CLCF disabled. For more information, refer to Copper Loss Carry Forward in the User Guide section of this manual.
