2.2.3Eight-Port Copper Module, 6K8-RJ45

The 6K8-Series’s 8-port Copper port module, model 6K8-RJ45, provides eight 10/100Mb switched RJ-45 ports. The 10/100Mb switched ports normally (as a default setting) are independently N-way auto-negotiating, and auto-crossover(MDIX) for operation at 10 or 100Mb speed in full- or half-duplex mode, i.e., each independently selects a mode and speed to match the device at the other end of the twisted pair cable.

(See Section 4.3 for auto-negotiation and MDIX details). The auto-crossover feature will automatically determine the other side of connection to make the connection, and eliminate the need of cross-over cable.

On the model 6K8-RJ45 module, there are four LEDs for each port, two in the connector and two separate. The LK (Link) LED indicates “ready for operation” on that port when lit. The blinking ACT (Activity) LED indicates receiving Activity on that port when lit. The 10/100 LED indicates operation at 100Mb speed when ON and at 10 Mb speed when OFF (when auto-negotiation is not disabled). The FDX/HDX LED is ON to indicate full-duplex operation

and OFF to indicate half-		1	3	5		7
duplex mode. A twisted pair	10/100						LK

(LK) indicator for that port
	10/100						LK
must be ON (indicating there

order for a LK LED to provide valid indications of operating conditions on that port.

Using the 6K8-Series (MNS-6K) management software, the user may disable auto-negotiation and fix the desired operation of each RJ-45 port. User may select 10Mb or 100Mb speed and full- or half-duplex mode per-port as per user requirement. (See Magnum MNS-6K Software Manual for details info.).

The combo six-port modules are combinations of copper and fiber media, available as four 10/100 switched RJ-45 copper ports and two 100Mb switched multi-mode fiber in either ST, SC, single mode SC or Long Reach SC ports. For port numbering, ports 1,3,5,7 are copper, ports 2 and 6 are fiber, and ports 4 and 8 are not present.

The four RJ-45 ports operate just like the 8-port copper module with auto-cross
