..
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 6K25e. 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 6K25e passes the
1613specifications for zero packet loss with fiber ports & with RJ45 ports used
as indicated here.
5.2.10 New PoE(Power Inside), model PI6KP8-45RJ (MDIX), 10/100Mb 8-port
The PoE RJ-45 ports act similar to regular RJ-45 ports, except they have
capability of providing power on each port to power up the PD devices, per the
IEEE802.3af PoE
standard. Only 4 x RJ-
45 (10/100) ports
maxm. support
POE(Power Inside)
option in one 6K-unit.
In this Fig. the top 4-
RJ45 ports are
enhanced with POE
option whereas as
bottom 4- RJ-45 are
normal MDIX ports.
The 4-RJ45 POE
module are also
available with mix –n-
match with fiber modules. Please check the ordering information Sec.1.2. for all the
various PI6K PoE modules option.
