UTP Full/Half Duplex “FDX/HDX” DIP-Switch:

When the UTP “AN/Man” DIP-Switch is in the “Man” position, the UTP Full/Half-Duplex DIP-Switch determines the duplex operation mode for the UTP port.

Setting the UTP Full/Half-Duplex DIP-Switch to UTP Full-Duplex “FDX” (factory setting) position forces the UTP port to operate in Full-Duplex. Setting this DIP-Switch to UTP Half-Duplex “HDX” forces the UTP port to operate in Half-Duplex. Adjust the UTP Half/Full-Duplex DIP-Switch to match the connecting device.

When the UTP “AN/Man” DIP-Switch is in the Auto Negotiate “AN” position, and the UTP Full/Half Duplex DIP-Switch is in the Full-Duplex “FDX” position, the UTP port auto-negotiates to Full or Half-Duplex. When in the Half-Duplex “HDX” position, the UTP port functions only in Half-Duplex.

A Port Backplane Enabled “A EN” DIP-Switch:

When the “A EN” DIP-Switch is in the left position (factory default), the 10/100VT module’s Backplane Ethernet A port is isolated from the backplane. When the “A EN” DIP-Switch is in the right position, the 10/100VT module’s Backplane Ethernet A port is enabled. This port allows connectivity to an adjacent module.

BPort Backplane Enabled “B EN” DIP-Switch: When the “B EN” DIP-Switch is in the left position (factory default), the 10/100VT module’s Backplane Ethernet B port is isolated from the backplane. When the “B EN” DIP-Switch is in the right position, the 10/100VT module’s Backplane Ethernet B port is enabled. This port allows connectivity to an adjacent module.

Link Propagate/Link Segment “LP” DIP-Switch:

This DIP-Switch controls the selection of Link Propagate

OVERVIEW:

The iConverter 10/100VT provides 100BASE-FX fiber to 10BASE-T or 100BASE-TX UTP conversion, as well as rate conversion between 10BASE-T and 100BASE-TX. Models are available for multimode (MM) and single-mode (SM) dual fiber, and single-mode single-fiber (SF).

The 10/100VT supports Half-Duplex and Full-Duplex modes and features an automatic crossover mode for easy attachment to hubs, switches and workstations.

The 10/100VT can be used as a standard two-port UTP to fiber converter. It can also use its two additional 10/100 backplane ports to connect to adjacent modules and accommodate flexible network configurations like in-band management and multi-module configurations. The iConverter 19-Module, 5-Module and 2-Module Chassis have backplanes that facilitate connectivity between adjacent modules.

The 10/100VT can be used in an unmanaged or managed fashion. When unmanaged, it can be installed in an iConverter chassis without a Network Management Module (NMM). To be managed, an NMM module or an iConverter module with integrated management, such as the 10/100M, must be installed in the same chassis as the 10/100VT.

Advanced Features:

The 10/100VT features Port VLAN and Tag VLAN, which allow complete control of traffic flow between the fiber port, UTP port, and the chassis Backplane Ethernet ports on a module. Other advanced features include Port Access Control, which facilitates enabling and disabling of individual ports, individual Port Bandwidth Control and reporting of MIB statistics.

Note that using the Advanced Features listed above require the use of the NMM (or an iConverter module with integrated management) and the NetOutlook™ Management Software, third-party SNMP management software or Telnet.

For more information on using and configuring the Advanced Features, please refer to the NetOutlook Management Software user manual.

or Link Segment modes. When this DIP-Switch is in the left “LS” position (factory setting), Link Segment mode is enabled. When this DIP-Switch position is in the right “LP” position, Link Propagate “LP” mode is enabled. In this mode, the iConverter propagates the presence or absence of an incoming “Link” signal from one port to the other.

Note that for Link Segment mode, the “LP”, “RFD” and “SFD” DIP-Switches must be in the Left or “Off” position (factory default).

Note that setting both “LP” and “SFD” link mode DIP-Switches (or setting both “RFD” and “SFD” link mode DIP-Switches) to the Right position on the same module is an illegal mode that will result in Link Segment behavior.

Remote Fault Detection “RFD” DIP-Switch:

When in the right switch position, the Remote Fault Detection “RFD” mode is enabled. In RFD mode, the 10/100VT propagates the presence or absence of an incoming “Link” signal from a Fiber port receive side to the transmit side of the Fiber port.

When this DIP-Switch is in the right “RFD” position and the “LS/LP” DIP-Switch is in the right “LP” position, Remote Fault Detection + Link Propagation mode is enabled. In “RFD+LP” mode, the 10/100VT propagates the presence or absence of an incoming “Link” signal from a Fiber port receive side to the transmit side of both the Fiber and the UTP ports.

Connecting two converters with both set to RFD mode is illegal and will cause a “deadly embrace” lockup.

Symmetrical Fault Detection “SFD” DIP-Switch:

When in the right switch position, the Symmetrical Fault Detection “SFD” mode is enabled. In this mode, two 10/100VT media converters can be deployed in tandem so that the absence of an incoming “Link” signal to any port on either media converter forces the absence of a “Link” signal on all other ports of both media converters.

Factory Test “TEST” DIP-Switch:

This DIP-Switch is for factory use only and must always be left in the left position (factory default).

PORT STRUCTURE:

Using a 4-port switch design, the 10/100VT features one front-plane 100Mbps fiber port, one front-plane 10/100Mbps UTP port and two 10/100Mbps Ethernet Backplane ports (“A” and “B”). The Backplane ports can connect to adjacent modules within the same chassis.

When the 10/100VT “A” and “B” Backplane ports are enabled (using the board-mounted “A EN” and “B EN” DIP-Switches), they connect via the chassis’ backplane to the slots on the left and right sides of the 10/100VT module. When another switch-based module with Backplane port connections such as a second 10/100VT or an NMM is installed in an adjacent slot, it can be connected via the backplane to the 10/100VT to facilitate a multi-module configuration.

Fig. 1 In-Band Managed 10/100VT Application

Fig. 1 depicts a chassis with three modules plugged into three of its adjacent backplane slots. The adjacent slots are connected via the backplane using the “A” and “B” 10/100 links. In this example, the 10/100VT 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 Network Management Module (NMM) and it connects via its “A” Backplane port to the 10/100VT facilitating in-band management (via the fiber uplink). The module on the right is a 4-port 10/100 switch module (4Tx) and it connects via

RJ45 Crossover “=/X” Switch (not shown):

Although the 10/100VT features auto-crossover, some devices may have problems completing the link. When connecting the UTP to a hub or switch, set this switch to SWITCH “X” (factory setting). When connecting to a workstation, set to CROSSOVER “=”.

MOUNTING AND CABLE ATTACHMENT:

iConverter modules are hot-swappable and can be installed into any chassis in the iConverter family.

1.Carefully slide the iConverter module into the installation slot, aligning the module with the installation guides. Ensure that the module is firmly seated against the backplane.

2.Secure the module by securing the panel fastener screw (attached to module) to chassis front.

3.Attach the UTP port via a category 5 cable to a 10BASE-T or 100BASE-TX Ethernet device.

4.Attach the fiber port via an appropriate multimode or single-mode fiber cable to a 100Base-Fx Fast Ethernet device. The iConverter transmit (Tx) must attach to the receive side on the other device; the receive (Rx) must attach to the transmit.

5.When using single-fiber (SF) media converter models, the Tx wavelength on one end has to match the Rx wavelength on the other. Note that based on this guideline the SF media converter models must be used in pairs, such as the 8810-1 matched with the 8811-1.

Note that when hot-swapping a 10/100VT module (removing it from the chassis and reinserting it), a period of three seconds must pass between removing and reinserting the module.

UPDATING 10/100VT FIRMWARE:

Updating the 10/100VT firmware requires an NMM to be installed in the same chassis. The new 10/100VT firmware is uploaded to the NMM’s FTP server and then installed in the 10/100VT.

For more information on updating the 10/100VT firmware, please refer to the NMM user manual.

its “B” backplane port to the 10/100VT facilitating a 5-port 10/100 Ethernet switch with a fiber uplink configuration.

This example shows how the 10/100VT can be used as a managed or unmanaged media converter to create flexible and effective network switch configurations.

To find out about individual chassis “A” and “B” backplane links, refer to the specific chassis’ user manual.

LINK MODES:

In order to accommodate different user needs, the 10/100VT supports several different linking modes.

In “Link Segment” (LS), sometimes referred to as the “Normal” mode, a port transmits a “Link” signal independently of any received “Link” at any other port. For example, the UTP transmits a “Link” regardless of the fiber receiving a “Link” [Fig. 2(a) & (b)].

In “Link Propagate” (LP), sometimes referred to as “Link Loss Carry Forward”, a port transmits a “Link” signal only when receiving a “Link” at its other port. For example, the UTP transmits a “Link” only when receiving a “Link” at the fiber port [Fig. 2(c)].

In “Remote Fault Detection” (RFD), the fiber port transmits a “Link” signal only when receiving a “Link” at the fiber port. As a result, fiber faults (no “Link” received at the fiber) are looped-back and can be reported to the network core [Fig. 2(d)].

In “Remote Fault Detection + Link Propagate” (RFD+LP), the UTP port transmits a “Link” signal only when receiving a “Link” at the fiber port. The fiber port transmits a “Link” only when receiving “Link” signals both at the fiber port and the UTP port. As a result, fiber faults (no “Link” received at the fiber) are looped-back and can be reported to the network core [Fig. 2(e)].

Note that connecting two converters with both set to RFD mode is illegal and will cause a “deadly embrace” lockup.

In “Symmetrical Fault Detection” (SFD), the UTP port transmits a “Link” signal only when receiving a “Link” at the fiber port. The fiber port transmits a “Link” only when receiving a “Link” signal both at the fiber port and the UTP

DIP-SWITCH SETTINGS:

Front Panel DIP-Switch Settings:

Fig. 3 Front Panel DIP-Switches

Fiber Full/Half-Duplex “FDX/HDX” DIP-Switch:

Setting this DIP-Switch to Full-Duplex “FDX” facilitates connecting to a switch or a workstation that supports Full- Duplex operation. Setting this DIP-Switch to Half-Duplex “HDX” facilitates connecting to a hub (with a shared/non- switched fiber port) or a workstation that supports only Half-Duplex.

UTP Auto/Manual “AN/Man” DIP-Switch:

Setting this DIP-Switch to UTP Auto-Negotiate “AN” (factory setting) enables the UTP port to determine the speed and duplex mode automatically. If the connected device cannot provide the proper signal to indicate its own mode of operation, the UTP Manual “Man” DIP-Switch setting should be used. This feature allows connections with devices that do not auto-negotiate properly.

UTP 10/100 DIP-Switch:

When the UTP “AN/Man” DIP-Switch (described above) is in the “Man” position, the UTP 10/100 DIP-Switch determines the speed of operation for the UTP port.

Setting the UTP 10/100 DIP-Switch to UTP 100Mbps “100” (factory setting) forces the UTP port to operate at 100Mbps. Setting this DIP-Switch to UTP 10Mbps “10” forces the UTP port to operate at 10Mbps. Adjust the UTP 10/100 DIP-Switch to match the speed of the connecting device.

When the UTP “AN/Man” DIP-Switch is in the Auto Negotiate “AN” position, and the UTP 10/100 DIP-Switch is in the “100” position, the UTP port auto-negotiates to 100Mbps or 10Mbps. When in the “10” position, the UTP port only operates at 10Mbps.
