* Note: The use of either multi-mode or single-mode fiber to operate at 1000Mbps speed
over long distances (i.e., over approx. 400 meters) can be achieved
only if the following
factors are both applied:
• The 1000Mb fiber segment must operate in full-duplex (FDX) mode, and
• The worst-case OPB of the fiber link must be greater than the fiber cable’s
passive Attenuation.
(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)
3.8.7 Connections to NICs which support Auto-Negotiation
The copper ports of Magnum CSG14 Series Converter Switches will function
properly with NICs (Network Interface Cards) which support Auto-Negotiation, and the
Fast Link Pulse (FLP) coding for the 1000BASE-T signaling system. When connecting a
NIC to the CSG14 Series, it may be necessary to reload the NIC drivers on the user device
if the NIC has been communicating with a protocol other than 1000BASE-T (such as
100BASE-TX). When 1000Mb operation is agreed and in use, the Gb LED is illuminated
steady ON and is OFF, for 10 or 100Mbps traffic.
