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.

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.
