How to stack Cisco 2960-S and Cisco 2960X?

Is there an easy way to stack Cisco 2960-S and Cisco 2960X switches? If you have no idea, follow this:

1. Stacking is not supported on switches running the LAN Lite image. All switches in the stack must be running the LAN Base image.
2. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, the number of supported stack members is reduced from eight to four.
3. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, full stack bandwidth is reduced from 80 Gbps to 40 Gbps.
4. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, stack convergence time is increased from milliseconds to 1 to 2 seconds.

NAME
SNMP::Info::CiscoStats - Perl5 Interface to CPU and Memory stats for Cisco Devices AUTHOR
Eric Miller, Max Baker, Sam Stickland SYNOPSIS
# Let SNMP::Info determine the correct subclass for you. my $ciscostats = new SNMP::Info( AutoSpecify => 1, Debug => 1, # These arguments are passed directly on to SNMP::Session DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost. "; my $class = $ciscostats->class(); print "SNMP::Info determined this device to fall under subclass : $class "; DESCRIPTION
SNMP::Info::CiscoStats is a subclass of SNMP::Info that provides cpu, memory, os and version information about Cisco Devices. Use or create in a subclass of SNMP::Info. Do not use directly. Inherited Classes None.
