and its connected device, whether
it’s a switch, a network interface
card (NIC), or another Layer 1
Gigabit Media Converter. To avoid
conflicts with devices connected
to the media converter, it senses
which mode is appropriate and
chooses either slave or master
mode.
To override the factory
defaults of duplex settings and
slave/master modes, you need
only to change an 8-position
DIP switch on the bottom of the
converter box and activate the
front-panel reset button.
Fault-detection features
The Layer 1 Gigabit Media
Converter has Link Integrity
features that prevent “silent
failures” on your network. What
this means is that the converter
identifies lost cable links. No more
time wasted searching for them! A
link can be checked by physically
observing the status of the media
converter’s Link LED.
One feature, FiberAlert™,
signals to you when a fault occurs
on one fiber strand and the link is,
in turn, incapable of carrying
bidirectional communications
between two fiber devices. If
a strand isn’t available and
you have FiberAlert enabled, the
device at the receiver end notes
the loss of the link and stops
transmitting data until it receives
a signal or link pulse.
Essentially, with FiberAlert, the
link status of one end is mirrored at
the opposite end. This means that
the link status can be seen at
both
ends
through the respective Link
LEDs, thus helping you to identify
and isolate faults anywhere in the
fiber loop. FiberAlert works even if
the fiber devices are separated by
great distances.
LinkLoss™ is a feature that‘s
similar to FiberAlert in that faults
on one port are mirrored on the
other. But in the case of LinkLoss,
a fault on the fiber port is mirrored
to an Ethernet twisted-pair port
rather than another fiber port.
So if the fiber link is lost at the
converter, the converter disables
the twisted-pair Link LED. With
LinkLoss enabled, the link status
of the fiber segment will always
be reflected by the twisted-pair
segment so you’re informed
quickly of fiber problems.
LEDs show activity, signal alerts
All selectable features on the
Layer 1 Gigabit Media Converter
are externally accessible, and
each port includes diagnostic
LEDs for easy monitoring of
activity on both connected cable
segments. In all, the box has seven
LEDs on its faceplate—four to the
right of the shielded RJ-45 UTP
jack and three to the right of the
fiber optic SC connectors.
The first set of LEDs signal
when data is detected on the
twisted-pair port, when you
establish a twisted-pair link,
when it’s operating in full-duplex
mode, and when the unit has
power.
The second LED set informs
you when the converter detects
data on the fiber port, when you
establish a fiber link, and when
FiberAlert is enabled.
