Planning a Stack
Here are the guidelines to planning a stack:
 A stack can have up to four x310 Series switches.
 A stack can have different models of x310 Series switches.
 Any x310 Series switch model can be the master switch of a stack.
 Switches connected with AT-StackXS/1.0 stacking cables should
be installed in a standard 19-inch equipment rack and not more
than one meter apart, the length of the stacking cable. The end
switches cannot be more than one meter apart if you want to
create the ring topology, shown in Figure 18 on page 52 and
Figure 19 on page 53.
 The wiring topology of the stack may be either linear or ring. Both
topologies offer the same in terms of speed, but the ring topology
adds wiring redundancy.
 The x310 Series stack may not contain other stacking switches,
such as x600 and x610 Series switches.
 The x310 Series switches do not need any additional software for
stacking. However, they do need stacking transceivers.
 All the switches must have the same licenses of optional features.
If you install an optional feature on one switch, you must install it
on all switches before assembling the stack.
