3Com Ethernet 100Base-TX transceiver - 0.15 m

Advantages: Simple, dual speed, small size
Disadvantages: Only 5 ports (?)

...Not much to say about this really. I bought this for a pound (!) on Ebay to connect to my router giving me 4 more ethernet ports to connect stuff to my network. That's all it does, gives you more connection; there's no firewall, DCHP, nothing, but then that's all in my router. Its 5 autosensing ports (Ethernet 10Base-T/100Base-TX - RJ-45)automatically detect the speed of the attached device to maximize network performance - with a data transfer rate of up to 100 Mbps. It really was a "plug-and-play" installation with no configuration needed, it connected straight into my network - I didn't even ned to read the manual ! The auto-sensing feature means that you can plug the "in" cable into any socket - another 3Com switch I have has a specific "in" port.

There's one (manually switched) MDI-MDIX port to provide simple "in" connection from a server, switch, or hub, and three other female RJ-45 ports to send the network signal out to 3 other items. The hub has an external power supply and a "CoolCurve" self-cooling design eliminating the need for a noisy fan. Its dimensions (height: 3.6cm, width: 23.1cm, depth: 13.6cm) allow it to fit nicely with other 3Com OfficeConnect units - special stacking clips are available. It's an "unmanaged" hub, so there...
