standard distances as per mentioned on 5.2.8. and the LEDs also acts similarly as

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 module is 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 cross-over 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 6K25. 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 6K25 passes the 1613specifications
for zero packet loss with fiber ports & with RJ45 ports used as indicated here.
