I bought this Switch to upgrade my core network to Gigabit. Which it does superbly. Its plug and play and designed to work with both 10/100/1000 devices. Some of my network (The router/firewall and wireless access point) still uses 100mbps ports and it shows them as an orange light, and the gigabit as green so you can easily see which devices are attatched where, and what speeds they are running at. Mine came with the rackmount kit, which makes it easy to attatch into any rack unit. Netgear make great products and the whole thing is sturdy, and powder coated blue. This is what netgear classify as an enterprise product, and their support system reflects that.
