3Com 3C17511TAAUS 1 x Port 10Base-X (Xenpak) Expansion Switch Module

Product Description

The 3Com 3C17511TAAUS is an expansion module designed to add a single 10 Mbps Ethernet port, utilizing the 10Base-X standard and a Xenpak transceiver interface. The Xenpak form factor was an early standard for high-speed network interfaces, primarily used for 10 Gigabit Ethernet, but in this context, it's specified for a 10 Mbps connection, suggesting a specific legacy application or module type within the 3Com ecosystem. This module is intended to be installed in compatible 3Com network switches or chassis that support Xenpak-based expansion modules. The 10Base-X designation refers to Ethernet operating at 10 Mbps over specific types of cabling, often copper. The inclusion of 'TAAUS' in the part number might indicate specific compliance or regional variations, possibly related to TAA (Trade Agreements Act) requirements. Given the 10 Mbps speed and Xenpak interface, this module likely served a purpose in older network infrastructures or for specific management functions where a basic 10 Mbps connection was sufficient. It represents a component for extending the port density of 3Com switches with a legacy Ethernet interface, catering to environments that may still have older equipment or require dedicated low-speed connections.
