C2960S-F-STACK is a Stack Module, Cisco's Catalyst 2960S Flexstack Stack Module (FE), for FlexStack 20 Gbps stacking in Catalyst 2960-SF switches. 2960-SF Fast Ethernet fit separates it from C2960S-STACK for Catalyst 2960-S gigabit models. A Cisco Catalyst 2960-SF stack module fits the rear stack-module slot and uses FlexStack cables between module ports. FlexStack gives the stack a unified data plane, one configuration and one IP address for management. Full-bandwidth cabling keeps redundant connections; an incomplete ring drops the stack to half bandwidth. Catalyst 2960-S and 2960-SF LAN Base switches can share one FlexStack stack when each switch carries its own matching module.
C2960S-F-STACK price for new stock is $624.75. C2960S-F-STACK refurb price is $84.00. C2960S-F-STACK is in stock and available for free next-day delivery. (terms applied)

20 Gbps of stack bandwidth applies to the FlexStack technology, not to each module port. Four switches is the stack limit, so order one C2960S-F-STACK for every Catalyst 2960-SF stack member and count FlexStack cables separately. Two stack ports on the module create redundant full-ring cabling when the last switch is cabled back to the first switch. Half-ring cabling removes redundant connections and leaves half bandwidth. The FlexStack module is hot-swappable, and a switch must be powered off before that switch is added to or removed from an existing stack. The rear slot uses a blank cover before module installation.
C2960S-F-STACK is offered in new sealed and certified refurbished condition. Certified refurbished units are inspected and bench-tested between two compatible switches; module seats and locks in the rear slot and is recognized by the switch. Cisco service ended on 30 November 2020, so ORM's warranty is the cover that applies. Match one module to each 2960-SF member before the PO. New carries up to 3-year extended warranty, certified refurbished carries up to 1 year, and returns are 30 days on every condition; terms apply. UK, EU, US and MEA stock, RMA with advance replacement, PO accepted and Net-30 for government.

The buyer is replacing a failed rear-slot module after Cisco service ended on 30 November 2020. Match the 2960-SF switch model and keep one module per stack member, because a four-member stack needs four installed modules before cables are counted for the PO.
The buyer is adding another Catalyst 2960-SF LAN Base switch to an existing FlexStack stack. Count one rear-slot module for the added switch and one additional cable path to maintain the ring, then keep the stack at the four-member maximum.
The buyer is mixing Fast Ethernet and Gigabit 2960 access switches in one stack. Fit C2960S-F-STACK to each 2960-SF member and the matching 2960-S module to each 2960-S member, then hold the FlexStack count to four switches.
Catalyst 2960-S gigabit models
C2960S-F-STACK is the FE FlexStack module. Catalyst 2960-S Gigabit LAN Base switches take C2960S-STACK, so match the module to the switch sub-series before ordering.
Catalyst 2960-X stacks
Catalyst 2960-X LAN Base switches use FlexStack-Plus, not this FlexStack FE module. The replacement PID named for the migration is C2960X-STACK.
LAN Lite stack builds
LAN Lite 2960-S models have no FlexStack stacking in the ordering table. Choose a LAN Base stacking-capable switch before selecting the module.

C2960S-F-STACK is the Cisco Catalyst 2960S Flexstack Stack Module (FE), a rear-slot FlexStack module for Catalyst 2960-SF Fast Ethernet stacks. The F segment marks the FE module variant. The spare form C2960S-F-STACK= carries the same product description. The stack technology is FlexStack at 20 Gbps.
C2960S-F-STACK fits Catalyst 2960-SF LAN Base Fast Ethernet switches that use the rear FlexStack slot. Catalyst 2960-S Gigabit LAN Base switches take C2960S-STACK instead, and Catalyst 2960-X LAN Base switches take C2960X-STACK. LAN Lite 2960-S models have no FlexStack stacking.
A Catalyst 2960-SF stack uses C2960S-F-STACK for the rear FlexStack module. The same FlexStack cable family supplies CAB-STK-E-0.5M, CAB-STK-E-1M and CAB-STK-E-3M lengths. A full four-member ring needs four installed modules and four stack cables.
C2960S-F-STACK provides FlexStack stacking at 20 Gbps of stack throughput. FlexStack gives one data plane, one configuration and one management IP address across the stack. Cross-stack features cover EtherChannel, SPAN and FlexLink, and the 2960-SF fit is the module edge.
C2960S-F-STACK count is one module per Catalyst 2960-SF stack member. A two-switch stack needs two modules, and a four-switch stack needs four modules. Count the FlexStack cables separately; a full ring uses one cable per switch. A chain uses one fewer cable.
A FlexStack stack contains four switches. Full-bandwidth cabling uses redundant connections, while incomplete cabling or a failed link leaves half bandwidth and no redundant connection. A bad link can partition the stack, so count cables to close the ring before the PO.
Yes, C2960S-F-STACK is hot-swappable in the rear stack-module slot. Remove the blank cover, slide the module until it snaps into place and secure the screws finger-tight. Power off a switch before adding it to or removing it from an existing stack.
Yes, C2960S-F-STACK can sit in the 2960-SF members of a mixed FlexStack stack. The 2960-S members use C2960S-STACK. The stack combines Fast Ethernet and Gigabit ports in one switch stack, with the four-member FlexStack limit still applying.
The replacement for C2960S-F-STACK is C2960X-STACK, the Catalyst 2960-X FlexStack Plus Stacking Module. The replacement moves the buyer to Catalyst 2960-X LAN Base hardware and FlexStack-Plus. Confirm the switch family, because C2960X-STACK does not fit the 2960-SF rear slot.
C2960S-F-STACK is the FE FlexStack module for Catalyst 2960-SF switches, while C2960S-STACK is the FlexStack module for Catalyst 2960-S Gigabit LAN Base switches. Both use FlexStack cables, so the difference is the switch sub-series rather than cable length.
C2960S-F-STACK is the Catalyst 2960-SF FlexStack FE module, while C2960X-STACK is the Catalyst 2960-X FlexStack-Plus module and the replacement PID. C2960X-STACK serves 2960-X LAN Base switches; choose by switch family before comparing stack bandwidth or cables.
Cisco stopped selling C2960S-F-STACK on 6 November 2015. Cisco service ended on 30 November 2020 for the Catalyst 2960-S and 2960-SF hardware in the same lifecycle set. The replacement PID for the module is C2960X-STACK for migration.
ORM Systems offers C2960S-F-STACK in new sealed and certified refurbished condition. New carries up to 3-year extended warranty, and certified refurbished carries up to 1 year. Returns are 30 days on every condition; terms apply. Cisco service ended on 30 November 2020, so ORM's warranty is the cover that applies.
