FORCING THE SPEED AND DUPLEX MODE
Manually set the twisted-pair ports on the iMcV-Giga-FiberLinX-III for 10 Mbps or
100, or 1000 Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps Full-Duplex,
10 Mbps Half-Duplex, 100 Mbps Full-Duplex, 100 Mbps Half-Duplex, 1000 Mbps
Full-Duplex, 1000 Mbps Half-Duplex). The Optics Port operates at 1000Mbps
Full-Duplex for fixed fiber transceivers, and can support 100Mbps as well as
gigabit fiber SFPs.
SELECTIVE ADVERTISING
Selective Advertising, when used in combination with Auto Negotiation,
advertises only the configured speed and duplex mode for the twisted pair port.
If a specific speed and/or duplex are desired, B&B Electronics recommends using
Selective Advertising, rather than Force Mode, when connecting to devices that
only use Auto Negotiation.
BANDWIDTH CONTROL
The iMcV-Giga-FiberLinX-III includes bi-directional bandwidth control
(configurable via iView
2
). This allows the bandwidth limit to be set independently
from the DATA Port to the OPTICS (or UPLINK) Port and vice versa in a single
iMcV-Giga-FiberLinX-III application. In a Host/Remote iMcV-Giga-FiberLinX-III
application, it can be set from the Host unit to the Remote unit and vice versa
(i.e., the bandwidth on the DATA ports on both the Host and Remote modules
can be limited independently).
LINK FAULT PASS THROUGH (LFPT)
Link Fault Pass Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end-user to visually detect that the Link
and the LNK LEDS will extinguish on the front faceplate of the module, when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.
The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and Ext Management.
LFPT can be enabled between any two ports. For example, if LFPT is configured
as “from” the Optics port “to” the Data port, when a fault occurs on the Optics
port,
both LEDs for those ports will extinguish. The end-user can decide which
