Applications
The Xerox LAN/Fax Express 21 dates from the mid-1990s, an era when shared fax servers were a practical alternative to installing a fax modem in every workstation. Devices like this sat between a LAN and one or more fax lines, letting users send and receive faxes directly from their desktops through server software without monopolizing a dedicated PC. The AUI network interface was the standard LAN connection method of that period, and the included Fibermux FX6691EZ transceiver converts AUI to standard 10BASE-T twisted-pair — common in offices that had already moved to RJ-45 wiring. The RS-232 and parallel ports on the rear allowed direct connection to external fax modems or fax machines. Today these units are primarily of interest to legacy network administrators maintaining period-correct office infrastructure, collectors of 1990s office networking equipment, and technicians supporting older Xerox document environments.
This Xerox LAN/Fax Express 21 (Product Code 6L3) network fax server has been inspected and appears to be in good condition. The unit shows normal cosmetic wear consistent with prior office use — the top cover has light surface scuffing and the label area shows some wear, but the casing is intact with no cracks or major damage. The Fibermux FX6691EZ AUI-to-UTP transceiver is attached and included. Rear ports — including the two DB9 RS-232 serial ports, DB25 parallel port, and AUI connector — are present and appear undamaged. Please view our photo set and contact us if you have any questions.
