When installed in a Magnum 6K8-Series Switch, it supports the standard distances as per
mentioned on 5.2.8. and the LEDs also act similarly as mentioned above.
5.2.9 6KP8-RJ45
(Twisted Pair),
10/100Mb 8-Port
The 6KP8-
RJ45 module supports
Ethernet twisted pair
segments of any standard
length. It is equipped
with an eight-port RJ-45
connector, and offers
10/100 full / half-duplex
auto-negotiating capability on each port. The RJ-45 connector is shielded to minimize
emissions and will allow both unshielded twisted pair (UTP) and shielded twisted pair
(STP) cable connections. The 6KP8-RJ45 modules are equipped with a Media Dependent
Auto-Crossover (MDI-X) switch, which controls all ports for cascaded connection. This
feature eliminates the need for a special twisted pair crossover cable when connecting to
a hub or another switch.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a
“10/100” LED indicating 100Mb when lit (or 10 Mbps when off).
Important Note: The 10/100 RJ-45 ports are supported with Auto-negotiation and
Auto-crossover (MDIX), which allow the RJ-45 ports to automatically Link with any RJ-
45 device and eliminate the use of crossover cable.
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 6K8. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6K8 passes the 1613specifications
for zero packet loss with fiber ports & with RJ45 ports used as indicated here.
