Stacking Cable Redundancy

You can connect two units with two stacking cables as shown in, in case of a stacking port, module, or

cable failure. Removal of only one of the cables does not trigger a reset.

LED Status Indicators on an S-Series Stack

The stack unit is displayed in an LED panel on the front of each switch. Each panel displays the stack unit

ID — from 0 through 7 — and:

• A for the management unit

• Bfor the standby management unit

• 0 for stack members

Add a Unit to an S-Series Stack

If you are adding units to a stack, you can either:

• allow FTOS to automatically assign the new unit a position in the stack, or

• manually determine each units position in the stack by configuring each unit to correspond with the

stack before connecting it
