Magnum 6K25e Gigabit Fiber Switch Installation and User Guide (10/07)

In an eight-port SFF fiber port module, all of the fiber ports are of the same speed (100Mb), mode, and connector type. Models are available with Small Form Factor

	2	4		6		8			6K25e’s normally are set (factory

default) to operate in full-duplex mode for best fiber distance and performance. Using the 6K25e’s MNS software, the user may select full- or half-duplex mode per-port through set-up of the software (See Magnum 6K25e 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.

(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
