How many switches can be stacked in Cisco?
Cisco StackWise technology unites up to nine switches. The master switch manages each of these devices. Any member within the stacked unit can be the master switch. StackWise links Cisco Catalyst 3750 series switches into stacked units that are more easily deployed and managed.
How many switches we can add in stack?
You can add up to nine individual switches in a stack. Only the switch which has a special stacking module can join the stack. To connect stacking modules, a special stacking cable is used. All member switches of the stack select a master switch.
How do you tell if a switch is in a stack?
A switch stack is identified in the network by its bridge ID and, if it is operating as a Layer 3 device, its router MAC address. The bridge ID and router MAC address are determined by the MAC address of the stack master. Every stack member is identified by its own stack member number.
What is special about stackable switches?
A so-called stackable switch means that a switch generally has both “UP” and “DOWN” stack ports. When multiple switches are connected together, they act like a modular switch, and the stacked switches can be managed as a single unit.

How does Cisco stackpower work in a Cisco switch?
Cisco Stackpower technology is a new feature introduced in the Cisco catalyst 3750-X series switches that aggregates all of the available power in a stack of switches and manages it as one common power tool. The catalyst 3750X has two power supplies per system which allows the power load to be split between them.
How many Watts Does a catalyst 3750x need?
The catalyst 3750X has two power supplies per system which allows the power load to be split between them. This system increases the maximum power per port to 30 Watts to meet the POE+ standard (802.3at). Wih POE+, a 48 port system would need 1440 Watts to provide 30 Watts per port per powered device.
How many switches can be in a power stack?
A power stack can not contain more than four switches and Power Supplies of these switches can be managed as one large Power Supply that provides power to all switches. In this way, any faulty Power Supply in a single switch can be replaced without taking that switch offline.
