Figure 4.3 : Up-link on RJ-45 Port#1X
Magnum 4K24's each have one Up-link port, port # 1X, which can be used
when regular port #1 is not connected. The Up-link port allows non-node (switch-to-
repeater, switch-to-switch, etc.) connections without a special cross-over cable. It
works the same for 10Mb or 100Mb connections.
Use port #1 (or ports 2 thru 24) for straight-through twisted pair cabling
from the 4K24 switched port to a user device, or the "1X" port for cross-over or up-
link segment connections from the first 4K24 port to a repeater or hub or switch.
Verify proper port connection by noting the port's LINK/ACT status, which is
illuminated when a proper link is made, and is blinking when there is activity.
Note: Port # 1 and Port # 1X, both RJ45 ports, are logically one port. Only one
of these ports, either # 1 or # 1X, may be used at any one time.

Auto-negotiation for RJ-45 (copper) ports
The 4K24 Switch's RJ-45 copper ports are N-way auto-negotiation. There are
4 different speed and F/H modes selection depending on what the other device supports.
These are: (1) 100Mb full-duplex, (2) 100Mb half-duplex, (3) 10 Mb full-duplex and (4)
10 Mb half-duplex.
The auto-negotiation logic will attempt to operate in descending order and will
