In an eight-port SFF fiber port module, all of the fiber ports are of the same
speed (100Mb), mode, and connector type. Models that are available with Small Form
Factor (SFF) are multi-mode MT-RJ or LC-type connectors, and single-mode LC-type
connectors.
The 100Mb fiber eight-port modules for the Magnum 6K32T & 6K32TRC
normally are set (factory default) to operate in full-duplex mode for best fiber distance
and performance. Using the 6K32T & 6K32TRC’s MNS software, the user may select
full- or half-duplex mode per-port through the set-up of the software (See the Magnum
6K32T & 6K32TRC MNS Software Manual for the flexibility to adapt to any FDX or
HDX type of Fast Ethernet devices).
There are three LED’s per fiber port. The Link (LK) LED indicates “ready for
operation” on that port when lit, the F/H LED indicates operation in full-duplex mode
when ON (half-duplex when OFF), and the blinking ACT LED indicates receiving
Activity on the port. A fiber cable must be connected into a SFF 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.
2.2.3 Eight-Port Copper
Module, 6K8-RJ45 (MDIX)
The 6K-Series’s 8-port Copper
port module, model 6K8-RJ45,
provides eight 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.
(See Section 4.3 for auto-negotiation and MDIX details). The auto-crossover feature will
automatically determine the other side of connection to make the connection, and
eliminate the need of cross-over cable.
