About the AccessEtherLinX/4

The AccessEtherLinX/4 Series enables service providers to offer differentiated data
networking or

VPN services to multi-tenant building and business customers.
Residing at the customer premises or at the service provider POP, AccessEtherLinX/4
provides
differentiating and separating

a VLAN-based Layer 2 entry point to the MAN fiber network, trunking,

customer traffic. Featuring SNMP management,
bandwidth control, QoS, traffic prioritization and multicast pruning (using IGMP v1,
v2), it is an ideal

solution for delivering Ethernet-based services to customers quickly

and cost-effectively.

AccessEtherLinX/4 offers configuration access via Telnet, serial console and SNMP
software. Software upgrades can be initiated via any one of these access methods
using a TFTP server. Additionally IMC’s iConfig/ iView² can be used for software
upgrades as a single source solution.

The AccessEtherLinX/4 includes
twisted pair),

four 10/100 twisted pair Ethernet downlink ports (for connecting

one Uplink port (either 100Base-FX fiber or 10/100

users/LANs) and an internal 100 - 240 ±10% AC power supply.

Single-strand fiber versions of the AccessEtherLinX/4 are also available.

Installing the AccessEtherLinX/4

The AccessEtherLinX/4 comes ready to install; there is no hardware configuration
required. All features, such as FiberAlert and Auto Negotiation, are software
configurable.

Place the AccessEtherLinX/4 on a flat surface, prior to installation. Attach the cables
between the AccessEtherLinX/4 and each device that will be interconnected and then
plug the unit into a reliable, filtered power source.

INSTALLATION TIP

1

Single-strand fiber products use optics that transmit and receive on two different wavelength.
Single-strand fiber products must be deployed in pairs, connecting two compatible single­strand fiber products. Connect the 852-10133 (1310 xmt and 1550 rcv), for example, to a
product with 1550 xmt and 1310 rcv, e.g. 852-10134 (1550 xmt and 1310 rcv.) The two
connected products must also have the same speed and distance capabilities (i.e. both are
single-mode [20km] or both are single/PLUS [40km]).

Features

AutoCross Feature for Twisted Pair Connection

All twisted pair ports on the AccessEtherLinX/4 include AutoCross, a feature which
automatically selects between a crossover workstation or pass-through connection
depending on the connected device.

Software Configurable Features

The FiberAlert, as well as Auto Negotiation (Selective Advertising) and Bandwidth
Control features are all configurable via the management software or via serial
configuration or Telnet session.

Refer to the AccessEtherLinX/4 help file for additional information.

About FiberAlert

The AccessEtherLinX/4 includes an advanced troubleshooting feature, FiberAlert,
which minimizes the problems associated with the loss of one strand of fiber. If a
strand is unavailable, the AccessEtherLinX/4 notes the loss of link. The device will
then stop transmitting data and the link signal until a signal or link pulse is received.
The result is that the link LED on both sides of the fiber connection will extinguish,
indicating a fault somewhere in the fiber loop. Using FiberAlert, a local site
administrator is notified of a fault and can quickly determine where a cable fault is
located.

NOTE

FiberAlert is not available/applicable on single-strand fiber products.

NOTE

Enable FiberAlert on ONE side of a media conversion only; Enabling it on both sides would

keep both transmitters off indefinitely!

Auto Negotiation, Duplex Mode and Speed

The twisted pair ports on the AccessEtherLinX/4 Auto Negotiate for speed and duplex
mode. This device can also selectively advertise or force the speed and duplex

2

mode. If the device has a fiber Uplink port, it does not Auto Negotiate; it always
operates at 100 Mbps Full-Duplex.

Auto Negotiation

The AccessEtherLinX/4 ships with Auto Negotiation enabled on the twisted pair ports.
In this mode, the twisted pair port negotiates for speed and duplex mode.

Forcing the Speed and Duplex Mode

The twisted pair downlink ports on the AccessEtherLinX/4 can also be manually set
for 10 Mbps or 100 Mbps operation and for Half- or Full-Duplex (i.e. 10 Mbps Full­Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps Half- Duplex).

Selective Advertising

Selective Advertising, when used in combination with Auto Negotiation, advertises
only the configured speed and duplex mode for the twisted pair port.

If a specific speed and/or duplex mode is desired, use Selective Advertising, rather
than Force Mode, when connecting to devices that ONLY Auto Negotiate.

Bandwidth Control

The AccessEtherLinX/4 includes bandwidth control functionality. Bandwidth can be
set independently, in 32 Kbps increments, on each downlink port, or bandwidth can
be assigned to the entire unit via the uplink port. Refer to the help file for software
configuration information.

About iView²

iView² is a cross-platform network management application for intelligent networking
devices. It features a graphic user interface (GUI) and gives network managers the
ability to monitor and control devices from virtually any 32-bit Windows platform.
iView² can also function as a snap-in module for many SNMP applications. Refer to
the help files for iView² and AccessEtherLinX/4 for information regarding configuring
and managing the AccessEtherLinX/4.

About iConfig

iConfig is an in-band configuration utility that lets users quickly and easily complete
the first stages of SNMP configuration for SNMP-manageable devices. Tasks iConfig
can perform include:

3

• Setting the IP address, subnet mask and default gateway

Defining the community strings and SNMP traps.

•

In addition to the above functions, iConfig offers an authorized IP address system and
access restriction to MIB groups supported by manageable devices. These extra
layers of security are purely optional and do not affect SNMP compatibility in any
way.

iConfig can be used to upload new versions of the system software and new MIB
information. It also offers diagnostic capabilities for faster resolution of technical
support issues. iConfig version 1.3 or above MUST be used for PROM updates.
HubControl32 and previous versions of iConfig will not work.

iConfig works with the following platforms:

Windows NT

•

Windows 2000

•

Windows XP

•

Windows Vista

•

iView² can be downloaded from the website: www:imcnetworks.com

SNMP Management

SNMP management and iConfig are available through the AccessEtherLinX/4 Uplink
port. This provides a higher level of security so end-users cannot access
management, alter settings, etc.

In order for the AccessEtherLinX/4 to allow for SNMP-management, the unit must be
assigned IP configuration information (e.g., IP address, subnet mask, etc.) There are
four ways to do so:

• Using iConfig

• Using the last Downlink port (port 4, depending on the model)

• Using DHCP (Dynamic Host control Protocol); DHCP must be enabled

through the serial configuration or Telnet, via iConfig

• Telnet (Default IP=10.10.10.10; subnet mask=255.0.0.0.

Configuring

In order for the AccessEtherLinX/4 to allow for SNMP-management, the unit must be
assigned IP configuration information (e.g., IP address, subnet mask, etc.) using
iConfig via iView²; the unit’s serial port or DHCP (Dynamic Host Control Protocol),
and Telnet. In addition to assigning an IP address and subnet mask, the former two
methods will also allow users to create community strings, assign access rights,
configure traps and more. However, iConfig offers more options than serial port
configuration.

After assigning an IP address, use iView² or another SNMP-compatible Network
Management System (NMS) to remotely configure, monitor and manage the
AccessEtherLinX/4.

About Serial Port Configuration

Use a DB-9 to RJ-45 cable to allow for serial port configuration on the Downlink Port
4 of the AccessEtherLinX/4. (See Appendix)

To connect the AccessEtherLinX to a terminal/computer, use a straight-through (pin­to-pin) cable. (If the computer/terminal has a COM port using a connection not
compatible with a DB-9 connector, use the pin connection chart for reference in
making a cable.) Make sure the cable length is less than 50 feet (15.24m). Plug one
end of the cable into the DB-9 connector and the other into the appropriate
computer/terminal port. Set the computer/terminal for

38.4K baud, 8 data bits, 1 stop bit, no parity

and

no flow control

About DHCP

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 manually through iConfig, an RS-232 Serial session, or Telnet.
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

8

received, the SNMP Management Module will reboot so that the new IP address will
take effect. Refer to the Main Configuration

About Serial Port Configuration

for more
information about Enabling/Disabling DHCP. When there is no DHCP server on the
network, use iConfig or serial configuration to manually set the IP addresses. When
DHCP is enabled, the IP address (default 10.10.10.10 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.

Enter

to open the VLAN Definition screen (refer to the screen examples in the “dl_Open
Mode— Configuring Multiple VLAN IDs Per Port“ and “Configuring a VLAN ID for
Each Port” sections).

Users can define up to 15 VLAN IDs. Valid VLAN IDs are 1 to 4,094.

11

NOTE

SNMP can only be associated with one VLAN group. Tags cannot be enabled on SNMP
traffic. Users can assign each port plus SNMP a priority in the VLAN Definition screen. The
high and low priority is determined by the Base VLAN of the unit. Use iView² to set the Base
VLAN priority; this value is not configurable via a serial/Telnet session.

Configuring Multiple VLAN IDs per Port

Make sure to configure the unit for dl_open mode and reboot the unit. Upon
enabling VLAN functionality, the following screen will appear:

When using dl_open mode, define up to 15 VLAN IDs. Configure the Uplink port for
Tags in order for it to accept VLAN tagged traffic. In this mode, users can configure
Downlink ports as Members of various VLAN IDs.

When defining a VLAN ID for SNMP, the Uplink port should also be a member of
this VLAN ID. The Downlink port can be configured as a member of the SNMP
VLAN.

Configuring a VLAN ID for Each Port

Make sure to configure the unit for dlsecure mode and reboot the unit. Upon
enabling VLAN functionality, the following screen will appear.

12

When using dlsecure mode, configure the Uplink port for Tags in order for it to
accept VLAN tagged traffic. Assign up to 15 VLAN IDs to the Uplink port and then
assign one of those VLAN IDs to each Downlink port and SNMP.

Base VLAN Priority

The Uplink port has two outgoing queues; one for high priority traffic and one for low
priority traffic. iView² can set a Base VLAN Priority to designate what will be high
priority and low priority; the default value is 4. If the Base VLAN Priority is 4, 0-3 are
low priority and 4-7 are high priority. If the Base VLAN Priority is 3, 0-2 are low
priority and 3-7 are high priority. In the VLAN Configuration screen (shown above), a
Priority (0 - 7) can be entered for each port and SNMP.

Port Configuration

The AccessEtherLinX/4 ports can be configured via serial configuration. Type

Enter

and press

to be taken to the Port Configuration screen. From this screen, users

ports

can enable/disable ports, configure FiberAlert and Auto Negotiation, etc. (This can
also be performed via iView².)

Using iView²

iView² is a network management application for IMC Networks’ intelligent
networking devices. It features a Graphic User Interface (GUI) and gives
network managers the ability to monitor and control products from a variety
of platforms.

Using iView² with HP OpenView

During the installation, the iView² application will ask if HP OpenView is
installed on the management PC. Click Yes to integrate the appropriate files.
Within Open View, select the IMC Networks on the Navigation toolbar. A
drop down list of IMC Products will display, and can be individually selected
for management and monitoring.

Other NMS Applications

If using an application other than iView² for management, integrate the
SNMP vendor MIBs, which can be found in the MIB directory on the CD or
the subdirectory of iView² installed on the chosen hard drive of a
workstation: MCIMCV2c.MIB.

Refer to the application's documentation for information on how MIB files
are integrated.

14

Update Manager

iView² offers the option of scheduling an update search for IMC Networks’ devices
listed in the Network outline. Within iView², select
navigation toolbar. Select

Update Manager Options

Tools/SNMP Options

, and a dialog box will be

from the

displayed, in which you can select when to run the update search. This option
enables the end user to determine if they have the latest firmware, and download the
latest if they do not. It does not automatically run the download, so the end user can
review the release notes included with the binary file, and decide whether to
download it or not.

UMA (Unified Management Agent)

Centralized management makes practical sense for networks of all sizes,
especially service provider networks that must monitor and upgrade large
quantities of devices. The Unified Management Agent (UMA) allows
operators to manage all IMC modules with on-board logic (FiberLinX-II
series) installed in an IMC Networks iMediaChassis series, with a single IP
address from a central location. In addition, UMA allows users to centrally
manage and administer firmware upgrades over multiple devices.

Requirements:

•

iView² ver 1.8 or higher AccessEtherLinX/4 firmware ver C3 or higher

For example, install 20 iMcV-FiberLinX-II devices in a 20 slot iMediaChassis
at the Central Office (CO) then connect each to a remote AccessEtherLinX/4
unit installed at the customers premise (CPE); UMA will then allow users to
manage all 41 devices (including the chassis at the CO) via a single IP
address. Users may still assign IP addresses to each iMcV-FiberLinX-II and
AccessEtherLinX/4, and manage them independently.

With the Unified Management Agent

When an SNMP request for an iMcV-FiberLinX-II comes in, the SNMP
Management Module in the iMediaChassis series passes the request to the
SNMP agent in the specific module. The SNMP agent in the iMcV­FiberLinX-II provides the relevant management information, which is then
routed via the SNMP Management Module and supplied to the client GUI,
as well as the serial port and Telnet.

File Management for Upgrading

The following screen, located in the iConfig utility of iView², shows the File
Management functionality of the Unified Management Agent. Operators can

15

easily upload and store new firmware versions for upgrading multiple devices
with on-board logic installed in, or connected to, an iMediaChassis series.

Using Telnet

Assign the AccessEtherLinX/4 an IP Address or use the default IP Address

10.10.10.10, subnet mask 255.0.0.0 before using a Telnet session. All configurations
done via the serial port can also be performed using Telnet. Use only one Telnet
session at a time. Do not use an RS-232 serial session and a Telnet session at the
same time.

Use Hyper Terminal to access the CLI (Command Line Interface). The manual will
describe how to do this.

vendor files (a.k.a. MIBs) into the application. The SNMP agent uses the following
Enterprise-specific MIB file and standard MIBs, which can be found in the MIB
directory on the CD included with the iMediaChassis/3: MCIMCV2C.MIB Enterprise
specific information for the agent. For example, configuration information, port type
information, link status, etc.

Using the IMC MIBs

Refer to the MIBs folder located with the iView² software for product-related MIBs.

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.

3.

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

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!

Integrated circuits and fiber optic components are
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.
