Magnum 6K8-Series Industrial Field Switch Installation and User Guide (04/07)

The default setup on the 10Mb fiber module is half-duplex, which allows the

Magnum 6K8-Series Switch to connect to any 10Mb hub or media converter or almost

any other device with a 10Mb fiber Ethernet port. The default setting of the 100Mb fiber

module is full duplex. User mode-control per port through the MNS “port settings”

software is the same as the other 6K8-Series modules.

The fiber ports support fiber-cabling distances according to the 10BASE-FL

and 100BASE-FX standards, i.e., 2km distance for multi-mode fiber. (Single-mode for

up to greater distance may be available as a special order, request quote).

2.2.7 Gigabit (1000Mbps) port modules

The Magnum 6K8-Series offers a wide range of optional Gigabit modules and

one or two Gigabit ports can be configured in one modular slot. The Gigabit modules are

the two ports GBPMV-2OTX, the 6KP5V-G4RJ (single Gigabit+4 10/100 RJ-45 ports)

or the 6KP3V-G2SC (single Gigabit+2 100Mb fiber ports) as shown below in the figure.

The 6K8-Series Modules provide a GBIC opening for insertion of industry-standard

GBICs to provide Gigabit media flexibility. GBIC models are available for both multi-

mode (550m) and single-mode (10, 25, 40, 70) km fiber options. Gigabit copper is also

available with new models appearing often.

The 1000Mb Gigabit fiber-port modules on the Magnum 6K8-Series are

normally set (factory default) to operate at AUTO mode for best fiber distance and

performance. The 1000Mbps SC fiber-optic module on the Gigabit -SX and Gigabit-LX

transceivers are compatible with the IEEE 802.3z Gigabit standards.

There are two LEDs mounted on each Gigabit port module. The Gigabit fiber

port is by default configured to AUTO mode, and can be fixed at 1000Mbps speed full-

duplex mode at any time. The Gigabit fiber port has LEDs that indicate LK (Link status)

and ACT (receiving activity) on that port when lit.
