Port VLAN
The Port VLAN mode allows you to configure the Managed Media Converter to accept only
data tagged with one specific VLAN ID. This mode can be configured for either the OPTICS
(or UPLINK) port or the DATA port.
Configuring DATA port VLAN
To configure this mode, perform the following:
1.
From the Main Configuration Screen, press the space bar and type
config
. The
Configuration Screen displays:
2.
Enter
N
in the Transparent Mode field and press any key (except S or Q) to open the
VLAN screen:
3.
Enter
Y
in the Tags column of the Data row and enter a VLAN ID in the VLAN IDs
Current column of the OPTICS row (for example, 13).

Valid Vlan IDs are between 1 and 4094. Valid priorities are between 0 and 7.
Type S or F3 to save the changes. Type Q or F4 to quit and cancel changes.
Transparent Mode – with either (not both) Data and Optics Mgmt dipswitches
set to on, all traffic passes between Optics and Data port EXCEPT what has
been defined as the Management Domain. The Management Domain can either be
defined as untagged traffic or traffic with a specified VLAN ID.
In Transparent Mode with BOTH Optics and Data Mgmt dipswitches set to off,
all traffic passes between the Optics and Data Ports.
Default Mode – the unit passes only Untagged Packets.
The unit is currently

FX/TX LinkLoss and FiberAlert
During normal operation, link integrity pulses are transmitted by all point-to-point Ethernet
devices. When a Managed Media Converter receives valid link pulses, it knows that the
device to which it is connected is up and sending pulses, and that the copper or fiber cable
coming from that device is intact. The appropriate “LNK” (link) LED is lit to indicate this.

Normal operation with no faults
The Managed Media Converter also sends out link pulses from its copper and fiber
transmitters, but normally has no way of knowing whether the cable to the other device is
intact and the link pulses are reaching the other end. The combination of FiberAlert and
LinkLoss allows this information to be obtained, even when physical access to a remote device
(and its link integrity LED) is not available.
