2.2.3Eight-Port Copper Module, 6K8-RJ45 The 6K25-Series’s8-port

Copper port module, model	10/100	1		3		5	7		LK
6K8-RJ45, provides eight
10/100Mb switched RJ-45								ACT
	F/ H
ports. The 10/100Mb switched	10/100		2		4	6	8		LK
ports normally (as a default	F/H
setting) are independently N-								ACT

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-		1	3	5	7
negotiation is not disabled).
	10/100					LK
The FDX/HDX LED is ON						ACT
to indicate full-duplex	F/ H	2	4	6	8
operation and OFF to indicate	10/100					LK
half-duplex mode. A twisted	F/H					ACT

pair cable must be connected

into an RJ-45 port and the Link (LK) indicator for that port must be ON (indicating there is a powered-up device at the other end of the cable) in 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.).
