Magnum 6KQE Managed Edge Switch Installation and User Guide | 02/09 |
(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-
