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
1
(for con-
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. Attach the cables between the
Access
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
Negotiation
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.

Downlink ports are isolated from one another (i.e. there is no communication between downlink ports).
