About Access EtherLinX/4
Access EtherLinX/4 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 , Access EtherLinX/4 provides a VLAN-based
Layer 2 entry point to the MAN fiber network, trunking, differentiating and separating
customer traffic. Featuring SNMP management, bandwidth control, QoS, traffic priori-
tization and multicast pruning (using IGMP v1, v2), it is an ideal solution for delivering
Ethernet-based services to customers quickly and cost-effectively. Access EtherLinX/4
also features Telnet, and firmware upgrading through serial configuration or Telnet via a
TFTP server. Access EtherLinX/4 includes one Uplink port (either 100Base-FX fiber or
10/100 twisted pair), four secure 10/100 twisted pair Ethernet downlink ports
necting users/LANs) and an internal AC power supply.
Installing Access EtherLinX/4
Access EtherLinX/4 comes ready to install. To install Access EtherLinX/4, make sure the
unit is placed on a suitable flat surface.
EtherLinX/4 and each device that will be interconnected, then plug the unit into a reli-
able, filtered power source. All features, such as FiberAlert and Auto-Negotiation, are
software-configurable. Refer to the help file for configuration information.
About FiberAlert
Access EtherLinX/4 includes the advanced troubleshooting feature, FiberAlert, which
minimizes the problems associated with the loss of one strand of fiber. If a strand is
unavailable, Access EtherLinX/4 notes the loss of link. The device will then stop trans-
mitting 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 go out indicating a fault some-
where 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. Please refer to the Help File
for FiberAlert configuration information.
Auto-Negotiation, Duplex Mode and Speed
The twisted pair ports on Access EtherLinX/4 auto-negotiate for speed and duplex
mode. This device also provides the option of selectively advertising or forcing the speed
and duplex mode. If the device has a fiber Uplink port, it does not auto-negotiate; it
always operates at 100 Mbps Full-Duplex. Configure features via the management soft-
ware. Please refer to the help file for more information.
Auto-N N egotiation
Access EtherLinX/4 ships from the factory with Auto-Negotiation enabled on the twist-
ed pair ports. In this mode, the twisted pair port negotiates for speed and duplex.
1 Downlink ports are isolated from one another (i.e. there is no communication between downlink ports).

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

Make sure the cable length is under 50 ft. (15.24 m). Plug one end of the cable into the DB-9 connector on Access EtherLinX/4 and the other into the appropriate port on your computer/terminal. Set your computer/ter- minal for VT-100 emulation. -
Page 4: Creating Community Strings
The purpose of community strings is to add a level of security to a network. The default community string is named “public” and has read/write access. IMC Networks recommends deleting Public, then adding necessary custom communities strings such as one with read-only access (for general use), the... -

Access EtherLinX/4 is VLAN compatible; it has the ability to accept traffic containing 802.1q VLAN tags on the Uplink port and direct that traffic to the twisted pair downlink ports or to manage- ment basedon VLAN ID.
- Page 7 D H C P B O U T There is a DHCP client in the Access EtherLinX/4. By default, the DHCP client is disabled. If a DHCP server is present on the network, the DHCP client will initiate a dialogue with the server during the boot up sequence. The server will then issue an IP address, Default Gateway and Subnet mask to the Access EtherLinX/4 chassis.
