Installation manual

Attach the cable to the media port

NOTE

Peripheral Component Interconnect (PCI) computers

automatically detect and configure PCI-compliant adapters

while booting. The AT-2560FX 100 and AT-2560TX 10/100

PCI adapter interrupt request (IRQ) number and I/O memory

address are automatically set each time you start your

computer.

In some mixed ISA/PCI PCs you must make sure the AT-

2560’s PCI slot has a unique IRQ level assigned. Allocation of

interrupts is controlled by the PCI computer’s Basic Input/

Output System (BIOS). Usually PCI IRQs are accessed

through menus of “CMOS Setup,” ISA Configuration Utility

(ICU), or “BIOS Setup” available when booting the computer.

See the PCI computer manual(s) for setup access and

instructions.

Attach the cable to the media port

AT-2560FX 100 PCI

The AT-2560FX 100 PCI provides the choice of either SC- or ST-

type duplex (transmit and receive) connectors for 100BASE-FX

Fast Ethernet. Figures 2 and 3 show the connector options.

WARNING

Hazardous light emissions may exist in fiber optic systems.

Severe eye damage may result if precautions are not taken.

Never look into a transmitting fiber optic device, transceiver,

repeater, or cable.

100BASE-FX wiring considerations.

Use either 50/100

m or 62.5/

125

m multimode fiber cables. For full-duplex operation, the

maximum cable run distance is two-kilometers, and for half-

duplex operation, the maximum distance is 412 meters.
