Omnitron Systems Technology 10T/2 プリント

to the slot on its left using the “A” link and to the slot on
its right using the “B” link.

In this example, the module on the left is an NMM and
it connects via its “A” link to the 10T/2 facilitating
In-Band management. The module on the right is an

 10/100 module and it connects via its “B”

link to the 10T/2 facilitating a 2-port 10/100 Ethernet
hub/switch with a 10BASE-2 port and a fiber uplink. This
3-module configuration provides an effective
10BASE-2 to 10/100 managed switch with a fiber uplink.

This example shows how the 10T/2 can be used either
as a traditional managed or unmanaged media converter
or to create flexible and effective network hub/switch
configurations.

DIP-Switch is in the “OFF” position, the 

10T/2 module’s A backplane Ethernet port will be isolated
from the backplane.

When the Backplane B Enable “B-EN” DIP-Switch is in
the “ON” position, the 

 10T/2 module’s B

backplane Ethernet port is enabled. This port allows
connectivity to adjacent modules and facilitates
In-Band management of the Network Management
Module (NMM). When the Backplane B Enable “B-EN”
DIP-Switch is in the “OFF” position, the 

10T/2 module’s B backplane Ethernet port will be isolated
from the backplane.

This switch is reserved for factory use, and should be
left in the “OFF” position.

The 

10T/2 converter supports the IEEE

802.3 standard and converts 10BASE-T cabling (UTP)
to 10BASE-2 coax cabling. The 

supports

Half-Duplex 10Mbps Ethernet and provides a crossover
UTP switch for easy attachment to hubs, switches and
workstations. It also features a termination switch for
easy coax termination.
The 10T/2 can be used as a standard two-port UTP to
fiber converter. It can also use its two additional
10/100 backplane Ethernet ports to connect to adjacent
modules and accommodate flexible network
configurations like In-Band management and multi-
module configurations. The 

19-Module,

5-Module or 2-Module Chassis have backplanes that
facilitate connectivity between adjacent modules.

The 10T/2  can be used in an unmanaged or managed
fashion. When unmanaged, it can be installed in a
chassis without a Network Management Module (NMM).
To be managed, a NMM module must be installed in the
same chassis.

Fig. 1 depicts a chassis with three modules plugged
into three of its adjacent backplane slots. The adjacent
slots are connected to the “A” and “B” backplane links
via the module’s “A” and “B” backplane Ethernet ports.
In this example, the 10T/2 in the center slot connects

Front Plane RJ45 Crossover “= / X” Switch:
When connecting to a workstation, set this DIP-Switch
to Straight-Through “=” (factory setting). When
connecting to a hub or switch, set to Crossover “X”.

When the Coax Termination “T-IN” DIP-Switch is in the

DIP-Switch setting when this coax port is at the end of
the network.

Backplane A Enable “A-EN” DIP-Switch:
When the Backplane A Enable “A-EN” DIP-Switch is in
the “ON” position, the 

10T/2 module’s “A”

backplane Ethernet port is enabled. This port allows
connectivity to adjacent modules and facilitates
In-Band management of the Network Management
Module (NMM). When the Backplane A Enable “A-EN”

modules are hot-swappable and can be

installed into any chassis in the 

family.

1. Carefully slide the 

module into the

installation slot, aligning the module with installation
guides, and secure using the front panel fastener
screw. NOTE: Ensure that module is firmly seated
against the backplane.

2. Secure module by securing panel fastener screw

(attached to module) to chassis front.

3. Attach the 

10T/2 RJ45 connector via a

category 5 cable to a 10Base-T Ethernet device.

4. Attach the 

10T/2, via a coax cable to a

10BASE-2 Ethernet device.

5. If using the 

10T/2 at the end of a coaxial

network, set Coax Termination “T-IN” DIP-Switch to
the “ON” position.
