Cisco FlexStack Stacking
Cisco FlexStack stacking with the hot-swappable
stack module and Cisco IOS
true stacking as all switches in a stack act as a
single switch unit. The Cisco FlexStack provides a
unified data plane, unified configuration, and single
IP address management for a group of switches.
The advantages of true stacking are lower total
cost of ownership through simplified management
and higher availability. Cisco FlexStack supports
cross-stack features including EtherChannel, SPAN
and FlexLink technology. A stack module can be
added to any Cisco Catalyst 2960-S switch with
LAN Base software to quickly upgrade the switch to
make it stack capable. Once a new switch is added
to a stack the switch will automatically upgrade
to the correct Cisco IOS
transparently become a stack member.
Software Features
• All Cisco Catalyst 2960-S Series Switches ship with the LAN Base image, with the exceptions of
WS-2960S-48TS-S and WS-C2960S-24TS-S.
• WS-2960S-48TS-S and WS-C2960S-24TS-S ship with the LAN Lite image and are not upgradeable to
LAN Base software.
• Some advanced features, like Cisco FlexStack, PoE+ and SFP+, require a the LAN Base image.

Power over Ethernet Plus
In addition to PoE 802.3af, the Cisco Catalyst
2960-S Series Switches support Power over
Ethernet Plus (PoE+) (IEEE 802.3at standard), which
provides up to 30W of power per port. The Cisco
Catalyst 2960-S Series Switches can provide a
lower total cost of ownership for deployments
that incorporate Cisco IP phones, Cisco Aironet
wireless LAN (WLAN) access points, or any IEEE
802.3af-compliant end device. PoE removes the
need for wall power to each PoE-enabled device
and eliminates the cost for additional electrical
cabling and circuits that would otherwise be
necessary in IP phone and WLAN deployments.
