Adaptec XHub7 Quick Start Guide - Page 12

Note: To stack your hubs without joining them (not pictured), remove the face plates from all but the top hub, and then just pile one hub on top of the other. Align the ports of each hub on one side of the pile for easy access; the LEDs will then be visible on the other side. Then follow Steps 3 and 4 below. 3 Connect a power adapter to each hub. (See Plugging in Your Hub on page 6.) 4 Connect your hubs to each other using a USB 2.0 cable, following the connection suggestions in the diagram below. XHub4/XHub4 Plus Use any USB port to connect to another XHub XHub7 Plus For maximum performance, use USB port 1, 3, or 5, especially when stacking more than two hubs. Making the Most of Your Daisy-Chain You can connect up to five XHub4s, or up to four XHub7s. The maximum number of hubs on a daisy-chain will vary if you use a combination of XHub4s and XHub7s. (This is a USB limitation.) 11
