Black Box DFCS 4Tx/L2 User Manual

Description

The DFCS
Module that supports the IEEE 802.3 Ethernet standard
and allows connectivity between 10Base-T and 100Base-Tx
unshielded twisted pair (UTP) devices on any of its
front-plane ports. The 4Tx/L2 fits the DFCS module
standard and can be used in any DFCS chassis.
The 4Tx/L2 supports Half-Duplex and Full-Duplex modes
Dynamic Fiber Conversion System
and features an automatic cross-over UTP circuitry
4Tx/L2 User Manual
that facilitates easy attachment to hubs, switches and
workstations.
All four front-plane ports operate in an auto-negotiation
mode and can auto-sense the proper speed and duplex
mode for optimal operation. All four front-plane ports

can be set via the network management to any desired
speed and duplex mode. Two of the four can also be

10/100 switch. It can also use its two additional 10/100
backplane ports to connect to adjacent modules and
accommodate flexible network configurations such as
in-band management and multi-module configurations.
The 4Tx/L2 can be used in an unmanaged or managed
fashion. When unmanaged, it can be installed in a chassis

4Tx/L2 is a 4-port 10/100 Ethernet Switch
The four front-plane 10/100 ports are designated as P1-P4
where P1 is located at the top (closest to the power LED)
and P4 is at the bottom (closest to the fastener screw).
When the 4Tx/L2 A and B ports are enabled (using the "BP
A EN" or "BP B EN" dip-switches), they connect via the
chassis' backplane to the slots to the left and right of the
4Tx/L2 module. When another switch-based module with
backplane port connections such as a 10/100T-Fx or a
MGT is installed in an adjacent slot, it can be connected
via the backplane to the 4Tx/L2 to facilitate a multi-module
configuration.

converter with fiber port) in the center slot connects 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 a MGT Module
and it connects via its A backplane port to the 10/100T-Fx
facilitating "In-Band" management (via the fiber uplink).
The module on the right is the 4Tx/L2 4-port switch module
and it connects via its B backplane port to the 10/100T-Fx
facilitating a 5-port 10/100 Ethernet switch with a fiber
uplink configuration. This 3-module configuration provides
an effective 5-port 10/100 managed switch with a fiber
uplink configuration.
This example shows how the 4Tx/L2 can be used as a
managed or unmanaged switch.

When in "MAN" (Manual) "left" position, the port does
not auto-negotiate and operates in the mode selected
by the P1 "10/100" and "HD/FD" dip-switches.

When in "MAN" (Manual) "left" position, the port does
not auto-negotiate and operates in the mode selected
by the P2 "10/100" and "HD/FD" dip-switches.
Port 2 "10/100" Speed Selection Dip-Switch
When the "AN/MAN" dip-switch is in the "MAN" position,
the P2 "10/100" dip-switch selects the speed of the P2
port. When in the right "100" position (factory setting),
P2 operates at 100 Mbps. When in the left "10" position,
P2 operates at 10 Mbps.
Port 2 "HD/FD" Full/Half Duplex Dip-Switch:
When the P2 "AN/MAN" switch is in the "MAN" position,
the P2 "HD/FD" switch selects the duplex mode of the P2
port. When in the "FD" (Full Duplex) "right" position (factory
setting), P2 operates in full duplex. When in the "HD"
(Half Duplex) "left" position, P2 operates in half duplex.
Note that attaching an auto-negotiating UTP port to a
non-auto-negotiating (manual / forced / hard-coded)
UTP port may result in an unpredictable port setting
with excessive collisions and poor link performance.
When operating in manual mode, both mating ports
MUST be set manually to the same speed and duplex
mode.
"RJ45 Cross-Over" Slide-Switch:
When the P1 "AN/MAN" switch is in the "MAN" position,
the "RJ45 Cross-Over" slide-switch controls the "Straight-
Through" or "Crossed" wiring of the P1 port. When
connecting P1 to a hub or switch, set slide-switch to the
"Switch" (factory setting) position. When connecting to a
workstation, set to "Workstation".
