The new Catalyst 3560-X and 3750-X switches are business class models of standalone (3560X) and stackable(3750X) switches for the aggregation and access network layers. Cisco’s latest innovations deliver new features like full Power over Ethernet (POE+), redundant power supplies, and Cisco StackPower on the 3750-X, features which are unavailable on the 3560-E, 3750-E and 3560G, 3750G models.
The Basics
Power over Ethernet Plus
The Catalyst 3750-X and 3560-X switches deliver PoE+ for a maximum power of 30W per port. The switches support both PoE standards, 802.3af and 802.3at, which define power maximums for an Ethernet a port.
Redundant Power and Fans
The Cisco 3560-X and 3750-X support dual redundant power supplies and fans. Redundant fans come standard. Four power supply options are available including a DC power supply for PoE. Only one power supply is required to run a single switch except when full PoE+ is deployed on a 48-port switch.
Power sharing capabilities
The Cisco StackPower can be deployed in three configurations: power-sharing mode, redundant mode, and RPS mode. Power-sharing mode aggregates and shares power within the switch stack. Redundant mode sets aside power from the stack for a 1+N redundancy. RPS mode is a one to one (1:N) redundancy with a designated power supply as backup. StackPower is limited to four switches in a ring topology.
StackWise Plus
Like StackWise technology, StackWise Plus enables the configuration of up to nine 3750 and 3750-X switches into a single logical switch. The stack promotes a single switching unit managed by a main switch which automatically works and updates all optional routing tables and switching. This feature is not available in 3560X
One surprising difference is that the 3750-X switch provides only 64 Gbps of backplane throughput whereas the older 3750-E delivers 128Gbps. As an alternative, the Juniper EX4200 has 128Gbps performance and can have ten switches in a virtual switch configuration for a total of 480 ports.
The 3560-X and 3750-X are standard Layer 2 switches which can be upgraded to Layer 3. This licensing option represents a cost.
3560-X and 3750-X models have a strong limited lifetime warranty that includes next business day replacement and 90 day access to Cisco TAC. Most competitive switch offerings have the NBD replacement as a chargeable support option.

hi, i have one switch 3750G 24 port & another 3750X 24 port.its can support the stacking or not..

Hi Dinesh, This is a actually a very good question which most of people dont know. Stackwise Plus is fully backward compatible and works with all sort of mixed stack on the same train.It will work !!!

Hi Pawan,thanks for your reply..which IOS is required in both the switches for stacking 3750G or 3750X.can we stack 12 port switch with 24 or 48 port
Pawan Sharma said:
You can use any IOS and any switch…
