Adding the STH to a Stack

3.2.2Adding the STH to a Stack

STH hubs are star-wired to the intelligent hub. To add STH hubs to a stack, refer to Figure 3-1 and perform the following steps:

1.Attach an STH HubSTACK Interconnect cable to the "STACK" port on the rear panel of an STH.

2.Attach the other end of the cable to one of the numbered STACK ports on the back panel of the intelligent hub.

The port’s number determines the relative position of the STH hub in the network’s ring sequence and is used by the intelligent hub’s management system to identify the STH to the user.

3.Repeat steps 1 and 2 to attach up to four STH hubs in the stack.
