ES42 Series Edge Switches
Installation and User Guide (05/05)
* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed
over long distances (i.e., over approx. 400 meters) can be achieved
only
if the following
factors are both applied:
•
The 100Mb 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)
3.8.6
Connections to NICs which support Auto-Negotiation, RJ-45 ports
The copper ports of Magnum ES42-Sereis Edge Switches will function properly
with NICs (Network Interface Cards) which support Auto-Negotiation, and the Fast Link
Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to the
ES42-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 100BASE-TX (such as 10BASE-T).
When 100Mb operation is agreed and in use, the 10/100 LED is illuminated steady ON and
is OFF, if 10 Mbps traffic.
