6KL4-RJ45, 4 x 10/100Mb RJ45 (Slot C)

The 6KL4-RJ45 4-port Copper module provides four 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).
(for auto-negotiation and MDIX details, see Section 4.2 in the 6KL User Guide).
On the model 6KL4-RJ45 module, there are three LEDs for each port, two
integrated into the connector, and one below the connector. The LK/ACT LED indicates
LK (Link) "ready for operation" on that port when lit. The ACT (Activity) LED indicates
receiving Activity on that port when blinking. 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 F/H LED is ON to indicate full-duplex operation and OFF to indicate the
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 6K (MNS-6K or MNS-6K-SECURE) management software, the
user may disable auto-negotiation and fix the desired operation of each RJ-45 port. The
user may select 10Mb or 100Mb speed and full- or half-duplex mode per-port as per user
requirements. (See Magnum MNS-6K Software Manual for additional info)
NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 ports are intended for
connectivity to other communication equipment such as routers or
telecommunication multiplexers installed in close proximity (i.e., less than 2
meters or 6.5ft) to the 6KL. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce high (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6KL passes the 1613specifications
for zero packet loss with fiber ports and with RJ-45 ports used as indicated
here.
