EtherLinX unit. Once you attach the brackets to the unit, install the Prisma
EtherLinX unit into the rack.
AutoCross Feature for Twisted-pair Connection
All twisted-pair ports on the Prisma EtherLinX unit include AutoCross, a feature
which automatically selects between a crossover workstation or pass-through
connection depending on the connected device.
Note: Since single-strand fiber products use optics that transmit and receive on two
different wavelengths, you must deploy single-strand fiber products in pairs, or
connect two compatible single-strand fiber products. 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)].

4008226 Rev B 19
Software Configurable Features
Introduction
The FiberAlert, Auto-Negotiation (Selective Advertising), and Bandwidth Control
features are all configurable via the management software or via serial configuration.
Refer to the Prisma EtherLinX unit Help file for software configuration information,
or refer to About Serial Port Configuration later in this document.
About FiberAlert
The Prisma EtherLinX unit includes the advanced troubleshooting feature,
FiberAlert, which minimizes the problems associated with the loss of one strand of
fiber. If a strand is unavailable, the Prisma EtherLinX unit notes the loss of link. The
device then stops 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 goes
out 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.
Auto-Negotiation, Duplex Mode and Speed
The twisted-pair ports on the Prisma EtherLinX unit 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 does not auto-negotiate; it
always operates at 100 Mbps Full-Duplex.
Auto-Negotiation
The Prisma EtherLinX unit ships from the factory 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 Prisma EtherLinX unit can also be manually
set for 10 Mbps or 100 Mbps operation and for Half- Duplex or Full-Duplex (i.e., 10
Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex, or 100 Mbps Half-
Duplex).
Continued on next page

20 4008226 Rev B
Software Configurable Features,Continued
Selective Advertising
Selective Advertising, when used in combination with Auto-Negotiation, advertises
only the configured speed and duplex mode for the twisted-pair port.
Note: If a specific speed and/or duplex mode are desired, it is recommended that
you use Selective Advertising, rather than Force Mode, when connecting to devices
that ONLY auto-negotiate.
Bandwidth Control
The Prisma EtherLinX unit includes bandwidth control functionality. You can
independently set bandwidth, in 32 Kbps increments, on each downlink port, or you
can set the bandwidth for the unit by assigning the uplink port a given amount.
Refer to the Help file for software configuration information.
