  • Plug-and-play installation makes network integration easy—even for amateurs!
  • 10-/100-Mbps autonegotiating and autosensing copper ports plus optional 100-Mbps fiber uplink ports make them a solid choice for migrating to Fast Ethernet.
  • Auto MDI/MDI-X on all copper ports eliminates the need for crossover cables.
  • Nonblocking switch architecture makes these units ideal for video and other data-intensive applications.
  • Store-and-forward switching technology reduces error packet propagation.
  • Get the 5-port model for smaller workgroups; get the 8-port model for larger workgroups.
  • Choose a 100–240-VAC external power supply or 110 VAC wallmount power supply.

    BLACK BOX® Palm-Sized Ethernet Switches are just what you need to get full-featured 10-/100-Mbps switching without breaking your budget or wasting space.

    Just look at all the big, big things this little switch can do!

    The 5-port and 8-port models each measure 1.1" high, 6.3" wide, and 3.2" deep. You can put them on a desk, on top of another box, even hide them behind your PC or Mac®. Wherever you put them, you'll save valuable space.

    All RJ-45 ports are autosensing and autonegotiating 10/100 Mbps, making Palm-Sized Ethernet Switches a perfect choice for networks running 10 Mbps, 100 Mbps, or a mixture of the two. Best of all, you don't have to configure any ports to match device speed—just plug the switches into your network.

    Choose a switch with a 100-Mbps fiber uplink port to connect a workgroup to a fiber backbone. Multimode fiber ports support distances of up to 2 km (1.2 mi.) and single-mode fiber ports support distances of 20 km (12 mi.). Multimode models are available with ST® or SC connectors; single-mode models have SC connectors.

    Both models use a nonblocking switching architecture that enables your network to handle almost any data-intensive application. Accounting office with spreadsheets? Video production company with imaging and multimedia applications? No problem for this switch!

    Don't worry about network efficiency or speed either. Store-and-forward switching technology eliminates error propagation, and wire-speed forwarding makes sure your network functions as quickly as you need it to.

    Save—don't sacrifice—with Palm-Sized Ethernet Switches from Black Box.
