5.1.2
10K4-RJ45, four 10/100Mb RJ45 ports (use in Slots E-H)
The 10K4-RJ45 four-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 this User Guide)
There are two LEDs per RJ-45 port on the module; one for Link/Activity and
one for F/H Duplex. For the 10K4-RJ45 LED designations, see Section 5.1.1.
A twisted pair cable must be connected into an RJ-45 port and the Link (L/A)
indicator for that port must be ON (indicating there is a powered-up device at the other
end of the cable) in order for the L/A LED to provide valid indications of operating
conditions on that port.
Using the 10KG management software (MNS-6K or MNS-6K-SECURE), 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
required. (See the Magnum MNS-6K Software Manual for additional info)
A module similar to Model 10K4-RJ45 is also available with IEEE 1588v2
Timing Synchronization as Model #
10K4T-RJ45
.
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 10KG. 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 10KG passes the 1613
specifications for zero packet loss with fiber ports and with RJ-45 ports used as
indicated here.
