2.2.3
Eight-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-
duplex mode. A twisted 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.).
2.2.4
Six-Port “4 + 2”Combo Modules, 4@ 10/100 RJ-45 and 2@100Mb
fiber
4@RJ-45 + 2@ 100Mb
ST or SC
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
