About the IE-iMcV-MultiWay

The IE-iMcV-MultiWay is a CPE device, available as a modular device providing two
fixed 10/100/1000Base-T copper ports and 2 SFP ports. The SFP ports support fiber
or copper SFPs. As a plug and play device, the IE-iMcV-MultiWay provides several
distinct modes of operation to support a wide range of applications. The IE-iMcV­MultiWay provides OAM functionality with 802.3ah and 802.1ag supported on each
port. It also supports jumbo frame sizes of up to 10,240 bytes as well as AutoCross
on the copper ports. As an Industrial Ethernet device, it supports an extended
temperature range of -40°C to +85°C. A console port and a DIP Switch bay provide
configuration options.

The IE-iMcV-MultiWay module is a single-wide module.

It can be installed in the following chassis:

• MediaChassis series

• IE-MediaChassis series

The IE-iMcV-MultiWay requires two small form-factor (SFP) modules which provide
greater fiber flexibility in the network environment. The hot-swappable nature of the
SFPs, available in dual strand for Multi Mode and Single Mode, and single strand fiber
types for Single Mode, allow for easy configuration and future upgrading as network
demands evolve. The SFP modules must be MSA-compliant and both DDMI and
non-DDMI are supported. The fiber SFP can support 100Mbps or 1000Mbps; while
the copper SFPs support 10/100/1000Mbps and 1000Mbps.

SFPs are sold separately by IMC Networks and meet Class 1 Laser Safety Standard.

As a CPE device, the IE-iMcV-MultiWay or IE-MultiWay can behave as a remote to an
iMcV-Giga-FiberLinX-II host when:

1) The iMcV-Giga-FiberLinX-II:

• Is connected via the SFP ports on the IE-iMcV-MultiWay

• Is configured as a Host

• Uses firmware version A1 860-00D1 or higher

2) The SNMP card (if present):

• Uses SNMP firmware version 953-00C8 or higher

2

When using iView2, the IE-iMcV-MultiWay can be fully managed without an IP
address using a secure management channel. However, an IP address can be
assigned through iView2 (iConfig view), the CLI or Telnet using the default IP address
of 10.10.10.10.

Operations, Administration and Maintenance (OAM)

OAM is a general term used in network management and is typically applied to a
series of standard protocols for installing, monitoring, and troubleshooting
Metropolitan Area Networks.

When applied to Ethernet – OAM is typically assumed to refer to the layer 2 (MAC
layer), management protocols, specifically 802.3ah and 802.1ag. Layer 2
management protocols do not need higher level transport protocols to operate, OAM
data is transferred in standard multicast Ethernet frames.

802.3ah OAM: Is a point-to-point protocol designed to verify a specific link between
two directly connected devices (over copper or fiber), which support 802.3ah OAM.
One device must be configured to be an active OAM device, the other a passive
(typically the core switch would be the active device, the end device passive).

802.3ah OAM provides link status, remote fault detection and the ability to initiate a
loopback circuit.

802.1ag: Often referred to as Connectivity Fault Management (CFM), is an end-to­end protocol designed to verify a specific network path between two devices that
may well be in different geographical locations. CFM allows the network operator to
administer, monitor and debug the network using continuity check (a heart beat
message), link trace (similar to traceroot, but operating at the MAC layer) and finally
loopback (can be likened to a layer 2 ping).

About iView² Management Software

iView² is the IMC Networks management software that features a GUI and gives
network managers the ability to monitor and control manageable IMC Networks
products.

The IE-iMcV-MultiWay is supported by the standalone version 1.9.4 or higher for
Windows.

iView2 supports the following platforms:

• Windows 2000

• Windows XP

• Windows Vista

• Windows 7

3

About iView2 (iConfig view)

iView2 (iConfig view) is an in-band utility created by IMC Networks, used for SNMP
configuration for IMC Networks’ SNMP-manageable devices.

2

The iView

(iConfig view) feature allows the following to be performed:

• Set an IP address, subnet mask and default gateway

• Define community strings and SNMP traps

2

iView

(iConfig view) also includes an authorized IP address system and restricted
access to MIB groups which are supported by IMC Networks’ manageable devices.
These extra layers of security do not affect SNMP compatibility. iView

2

(iConfig view)
can upload new versions of the system software and new MIB information. It also
includes diagnostic capabilities for faster resolution of technical support issues.

Installing an IE-iMcV-MultiWay

IE-iMcV-MultiWay should be installed in IMC networks’ unmanaged MediaChassis or
IE-MediaChassis series.

To install an IE-iMcV-MultiWay

Remove the blank bracket covering the slot where the module is to be

1.
installed by removing the screws on the outside edges of the bracket.

Slide the iMcV-Modules into the chassis, via the cardguides, until the

2.
module is seated securely in the connector.

Secure the module to the chassis by tightening the captive screws.

3.

4.

Save any “blanks” removed during installation for future use if the
configuration requirements change.

NOTE

This module is not designed to be installed in an iMediaChassis series with SNMP support.

DIP Switch Selectable Mode Configuration

The IE-iMcV-MultiWay can be configured in one of the following ways via DIP Switch
settings (see page 6):

Configuration

Method

4-Port Switch
(default)

Dual Converter
mode

1+1 SFP
Protection
Non-Revertive
mode

Description

In this mode, the unit acts as a standard 4-port MAC-layer switch.

In this mode, the unit functions as two independent (SFP to TX)
media converters and traffic never passes between the two
converters.

In this mode, the "SFP A" port (fiber or copper) is connected
through the switch to the drop ports as the main link. The "SFP B"
port (fiber or copper) is active into the MAC switch, but no
connection inside the switch is made; in this way, the "SFP B" line
is held as the standby line. The "SFP B" line is held in the LINK
state for testing and line verification, but does not actively carry
user data.

When a fault is detected on the active line, all customer traffic is
switched to the “SFP B” port. With non-Revertive mode data is
not resumed by “SFP A” port until SFP B fails or is disconnected.

1+1 SFP
Protection
Revertive
mode

In this mode, the "SFP A" port (fiber or copper) is connected
through the switch to the drop ports as the main link. The "SFP B"
port (fiber or copper) is active into the MAC switch, but no
connection inside the switch is made; in this way, the "SFP B" line
is held as the standby line. The "SFP B" line is held in the LINK
state for testing and line verification, but does not actively carry
user data.

When a fault is detected on the active line, all customer traffic is
switched to the “SFP B” port. Once the “A” port is no longer in a
fault condition, data is resumed on that port.

NOTE

Revertive and Non-Revertive modes can only operate on the ports with Gigabit SFPs, not the
fixed copper ports.

DHCP Disable (Static IP Addressing)

DHCP is disabled in the default configuration. Initially, modules are assigned a Static
default IP Address of 10.10.10.10. Changes to the Static IP Address can be added

2

manually through iView

(iConfig view) or a Console session. The changes will be

initiated following reboot of the module.

DHCP Enable (Dynamic IP Addressing)

If a DHCP server is present on the network and DHCP is enabled, the DHCP client
will initiate a dialogue with the server during the boot up sequence. The server will
then issue an IP address to the management card. Once the new IP address is
received, the SNMP Management Module will reboot so that the new IP address will
take effect. Refer to About Serial Port Configuration for more information about
Enabling/Disabling DHCP.

When there is no DHCP server on the network, use the serial configuration to
manually set the IP addresses.

When DHCP is enabled, the IP address (default 10.10.10.10 or a previously used IP
address, or user-configured) is saved. When DHCP is disabled, the saved IP address
will be reinstated and the device will reboot.

DHCP servers give out lease times: devices renew their leases based on the
administrator-specified time. If a device cannot renew its lease, and the lease expires,
the device will be given the IP address 10.10.10.10 and will reboot.

22

VLAN Configuration

The ports can be assigned as a trunk or access port.

When configuring a trunk port, an Ethertype can be user-defined (a trunk port is also
defined as a provider port based on 802.1ad). If an Ethertype value comes in a trunk
port and is different than the user-defined Ethertype, it will be treated as an
unrecognized value and discarded. If configuring the port as an access port, enter a
VLAN ID between 1 and 4,094. Possible priority settings are 0 (lowest priority)
through 7 (highest priority).

NOTE

When an Ethertype or VLAN ID is assigned, the same values need to be configured at the end
device (router, etc) to avoid network configuration problems.

Configuration File Save/Restore Function

Requirements

The Configuration File Save/Restore Function allows a user the ability to backup all
the configuration settings of a unit. With this backup, a user can restore settings to a
unit if necessary or use this backup to apply the same settings to a different unit.

All configurable managed objects are saved in a configuration file that is stored in the
unit’s Large File Area. This includes all configurable settings such as VLAN
configurations, IP Address configuration and SNMP agent settings. The configuration

2

file can be transferred from the unit to a PC and saved to disk through the iView
(iConfig view) protocol. The configuration file can be transferred from a PC to a unit
of the same type through iView

2

(iConfig view) or TFTP into the unit’s Large File Area.

After the transfer is complete, the unit copies the configuration to flash and reboots.

The configuration file’s contents is device-type specific and can be identified by

Troubleshooting

If a fiber connection cannot be established, perform the following to make sure that
the fiber transceivers on the IE-iMcV-MultiWay are not over/under driving the fiber
receivers:

Make sure the fiber wavelength on both connected devices match (i.e. both are

1.
1310 nm single-mode fiber).

Make sure the twisted-pair port speed on the IE-iMcV-MultiWay matches that of

2.
the end devices connected to the IE-iMcV-MultiWay. Configure the IE-iMcV­MultiWay and its link partner to Auto Negotiation or, if using Force mode, be
sure speed and duplex match.

IE-iMcV-MultiWay allows you to assign a VLAN tag to all management traffic

3.
(SNMP and telnet). It is important that you understand that IF you are using
telnet or iView2 to assign a VLAN tag to management traffic, then as soon as this
setting is saved you will lose connectivity to the device until the PC you are using
becomes a member of the VLAN you assigned to management traffic.

If you have assigned a VLAN tag to management traffic and cannot re-establish a
connection to the device via iView2 or telnet, you will need to directly connect a
PC to the device via the serial cable and review/modify the changes you made
(reference section on serial port config).

Fiber Optic Cleaning Guidelines

Fiber Optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector ferrules.

Use fiber patch cords (or connectors, if you terminate your own fiber) only from

1.
a reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.

Dust caps are installed at IMC Networks to ensure factory-clean optical devices.

2.
These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.

Store spare caps in a dust-free environment such as a sealed plastic bag or box

3.
so that when reinstalled they do not introduce any contamination to the optics.

If you suspect that the optics have been contaminated, alternate between

4.
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

52

Electrostatic Discharge Precautions

Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units, containing electronic components. Always observe the following
precautions when installing or handling these kinds of products

Do not remove unit from its protective packaging until ready to install.

1.

Wear an ESD wrist grounding strap before handling any module or component.

2.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.

Hold the units by the edges; do not touch the electronic components or gold

3.
connectors.

After removal, always place the boards on a grounded, static-free surface, ESD

4.
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.

WARNING!

extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
