About the Giga-AccessEtherLinX-II

The Giga-AccessEtherLinX-II 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, Giga­AccessEtherLinX-II provides

a VLAN-based Layer 2 entry point to the MAN fiber
network, trunking, differentiating and grooming customer traffic. Featuring remote
SNMP management,
prioritization and

port bandwidth control, QinQ support, QoS, traffic

multicast pruning (using IGMP v1, v2), it is an ideal solution for

delivering Ethernet-based services to customers quickly and cost-effectively.

Giga-AccessEtherLinX-II offers configuration access via Telnet, console, secure IP-Less,
and SNMP management channels. Software upgrades can be initiated via any one of
these access methods.

The Giga-AccessEtherLinX-II includes
10/100/1000 twisted pair) and

four 10/100/1000 Mbps twisted pair Ethernet

one Uplink port (either 1000Base-FX fiber or

Downlink Ports for connecting users/LANs, and supports jumbo frame sizes of up to
9600 bytes.

The Giga-AccessEtherLinX-II offers various wavelengths for SM and MM fiber at
gigabit speed; single-strand and SFP versions are also available. As a standalone unit,
it is available in an internal AC or DC version.

Installing the Giga-AccessEtherLinX-II

The Giga-AccessEtherLinX-II comes ready to install; there is no hardware
configuration required. All features, such as management access, qualified VLAN
tags, Link Fault Pass-Through and Auto Negotiation are software configurable.

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

INSTALLATION TIP

Single-strand fiber products use optics that transmit and receive on two different
wavelengths. Single-strand fiber products must be deployed in pairs, connecting two
compatible single-strand fiber products. Connect the 852-10310 (1310 xmt and 1550 rcv),
for example, to a product with 1550 xmt and 1310 rcv, e.g., 852-10311 (1550 xmt and
1310 rcv.) The two connected products must also have the same speed and distance
capabilities (i.e. both are single-mode [20 km] or both are single/PLUS [40 km]).

Features

Two Layer Qualified Q-in-Q Support

Each drop port can be assigned two different VLAN tags to incoming frames based on
the frames PRI or DSCP priority value and IP or Non-IP Frames types. In this way,
incoming traffic to the network can be groomed into different VLAN tributaries before
entering the network.

AutoCross Feature for Twisted Pair Connection

All twisted pair ports on the Giga-AccessEtherLinX-II include AutoCross, a feature
which automatically selects between a Crossover workstation or Pass-Through
connection depending on the connected device.

Software Configurable Features

The Link Fault Pass-Through, Selective Advertising, as well as Qualified VLAN tags
and Bandwidth Control features are all configurable via the SNMP IP-Less
management, DB-9 console configuration or Telnet session.

2

IP-Less Management in HOST/REMOTE configurations

A proprietary, secure management communication channel is supported whenever
the Giga-AccessEtherLinX-II unit is connected directly to an iMcV-GigaFiberLinX-II
unit over the Fiber Uplink. This secure communication channel does not require any
pre-configuration or IP address assignment. It automatically establishes an integrated
Host-Remote management connection between these units, allowing them to be
managed as a single unit, as long as the iMcV-Giga-FiberLinX-II unit is set to a unit via
the DIP Switch setting.

Priority Queuing and Flow Control

The unit supports two different priority queuing schemes. In all modes that do not
allow frame qualification, Priority Queuing is set globally for all ports as a Unit
Control Setting. For modes supporting Qualification, high priority is set individually
per port by the Qualification setting. Frames qualified as high priority will be given
preference over low priority frames to egress the unit.

When internal congestion occurs and the unit is low on internal buffer space, only
high priority frames will be allowed to enter the unit. If Flow Control is enabled,
PAUSE frames will be sent to all ports causing the congestion. If PAUSE frames are
received on a port, that port will not transmit frames until the PAUSE condition has
expired.

Auto Negotiation, Duplex Mode and Speed

The twisted pair ports on the Giga-AccessEtherLinX-II Auto Negotiate for speed and
duplex mode. This device can also selectively advertise or force the speed and
duplex mode. If the device has a fiber Uplink port, it always operates at 1000 Mbps
full-duplex and supports Auto Negotiation on the fiber segment.

Forcing the Speed and Duplex Mode

The twisted pair Downlink Ports on the Giga-AccessEtherLinX-II can also be manually
set for 10, 100, or 1000 Mbps operation and for half- or full-duplex mode (note:
1000 Mbps only supported in full 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 a Force Mode, when connecting to devices that ONLY auto negotiate.

Bandwidth Control

The Giga-AccessEtherLinX-II includes bandwidth control functionality. A maximum
bandwidth can be set independently on each port for both receive and transmit
directions.

About iView² Unit Management

iView² is a network management application for IMC Networks’ intelligent
networking devices. It features a GUI, which provides network managers the ability
to monitor and control IMC Networks’ products. The application is available in
several versions including Web-Server version 3.0 and can also function as a snap-in
module for HP OpenView Network Node Manager.

iView² supports the following platforms:

• Windows NT

• Windows 2000

• Windows XP

• Windows 7

• Windows Vista

Utility iConfig

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

The iConfig feature allows the following to be performed:

• Set an IP address, subnet mask and default gateway

• Define community strings and SNMP traps

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

Default Username/Password

The default user ID and password for both iConfig and Telnet are the following:

User: admin / Password:admin

4

SNMP, Telnet and Console Management

SNMP, Telnet, and iConfig management channels are always supported through the
Giga-AccessEtherLinX-II Uplink Port. This provides a higher level of security so end
users cannot access management, alter settings, etc. Management through other
ports can be supported through unit configuration.

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

• Using iConfig (IP-Less on same Ethernet Domain)

• Host-Remote IP-Less from an iMcV-GigaFiberLinX-II

• Using the console DB9 port located on the back of the unit

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

through the console configuration or Telnet

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

In addition to assigning an IP Address and subnet mask, the end user can create
community strings, assign access rights, and configure traps for total remote
management.

About Console Port Configuration

Use the console DB-9 port on the back of the unit to access the internal Command
Line Interface (CLI).

To connect the Giga-AccessEtherLinX-II to a terminal/computer, use a straight­through (pin-to-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
shown below 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

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

About Console Port Configuration

for more information
about Enabling/Disabling DHCP. When there is no DHCP server on the network, use
iConfig or console 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.
