(for auto-negotiation and MDIX details, see Section 4.2 in the 6KQE User Guide).
On the model 6KQE4-RJ45 module, there are four LEDs for each port, two
integrated into the connector, and two below the connector. The LK (Link) LED
indicates “ready for operation” on that port when lit. The blinking ACT (Activity) LED
indicates receiving Activity on that port when lit. The 10/100 LED indicates operation at
100Mb speed when ON and at 10 Mb speed when OFF (when auto-negotiation is not
disabled). The FDX/HDX LED is ON to indicate full-duplex operation and OFF to
indicate the half-duplex mode. A twisted pair cable must be connected into an RJ-45 port
and the Link (LK) indicator for that port must be ON (indicating there is a powered-up
device at the other end of the cable) in order for a LK LED to provide valid indications
of operating conditions on that port.
Using the 6K (MNS-6K or MNS-6K-SECURE) management software, 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 per user
requirements. (See Magnum MNS-6K Software Manual for additional info)
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 6KQE. 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 6KQE passes the
1613specifications for zero packet loss with fiber ports and with RJ-45 ports
used as indicated here.
5.1.4 6KQE4-1MMRJ, 1 x MTRJ / 3 x RJ45 (Slot C)
The 6KQE4-1MMRJ 4-port Fiber / Copper module provides one 100Mb
Multimode MTRJ Fiber port and three 10/100Mb switched RJ-45 ports.
The 6KQE4-1MMRJ fiber port is a Small Form Factor (SFF) MTRJ
Multimode connector. The MTRJ’s small size and ease of connection make it a good
choice for 100Mbps “fiber-to-the-desktop” Ethernet connectivity. When installed in a
Magnum 6KQE Series Switch, it supports fiber optic cable distances up to the IEEE-
