Network Cables User Manual

8 Installation Guide

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.

The “twister” offers the ease of plug-and-play installation.

Twisted-Pair Interface (2152-1x-01 only)

The twisted-pair port provides an auto-sensing RJ-45 connector that

supports a maximum segment length of 100 meters. Use Category 5e

cables. Because the port is auto-sensing, crossover cables are not needed.
