2.2.3 Get the stackable cable and connect the cable to the stacking connector
on the hub, as shown in Figure 2-8. Connect "Down" SCSI port of the upper
hub to "Up" SCSI port of the lower hub. Any loose connection of the stackable
cable will cause problems with network performance and quality.

2.2.4 If you are trying to add more hubs in your office, you can follow the
procedures from 2.2.2 to 2.2.3 repeatedly. Be sure not to stack hubs more
than 5 (include 5) sets in one stack.
2.2.5 Plug the power cord into the outlet on wall and check if the power LED
lights up. The hub is ready for network connection if the power LED lights up,
as shown in Figure 2-9.
