Catalyst 2940-8TT Switch - Quiet

by Nelson on 2/3/2009

I needed a fan-less switch, so there would be no vibration or noise around the unit. It is part of a conferencing system and it was mounted "hidden" on the foot of the conference table - so any noise would be amplified by the system. It works perfectly and is the second unit I own, with similar performance and durability / reliability.

Product Overview

The Cisco Catalyst 2940-8TT switch is small, standalone, managed switch with eight Fast Ethernet ports and a single integrated Fast Ethernet or Gigabit Ethernet uplink. The switch is designed to be used outside the wiring closet in the end-user workspace, and feature a durable metal shell, no fan for silent operation, easy wall or under-the-desk mounting, a security lock slot to prevent theft, and an available cable guard to secure the Ethernet cables and switch.
