CAB-STK-E-0.5M is a Cisco FlexStack 50cm stacking cable for 0.5 m FlexStack-Plus links at 80 Gbps on Catalyst 2960-XR and 2960-X switches. Its 0.5 m reach is the short option for adjacent rear stack ports; CAB-STK-E-1M gives 1 m for spaced switches. The Cisco Catalyst 2960-X stack cable also serves Catalyst 2960-S/SF FlexStack and FlexStack-Extended hybrid copper ports. Catalyst 2960-XR IP Lite stacks with IP Lite members, and Catalyst 2960-X LAN Base stacks with LAN Base members or the 40 Gbps, 4-member Catalyst 2960-S/SF mix. Rear STACK 1 and STACK 2 ports form a full ring with redundant connections for full bandwidth.
CAB-STK-E-0.5M price for new stock is $57.75, a 56.4% saving from the Cisco list price of $132.41. CAB-STK-E-0.5M refurb price is $50.40. CAB-STK-E-0.5M is in stock and available for free next-day delivery. (terms applied)

80 Gbps of stack bandwidth applies to Catalyst 2960-XR and 2960-X FlexStack-Plus stacks with 8 members. 40 Gbps applies to FlexStack-Extended stacks with 8 members, and 20 Gbps applies to Catalyst 2960-S/SF FlexStack stacks with 4 members. CAB-STK-E-0.5M connects STACK 1 to STACK 2; the connector tab faces up on STACK 1 and down on STACK 2. A half ring keeps the stack running at half bandwidth without the redundant connection. Catalyst 2960-X mixed with Catalyst 2960-S/SF runs at 40 Gbps with 4 members, and Catalyst 2960-XR does not join that mix. FlexStack-Extended needs Cisco IOS 15.2(6)E or later.
CAB-STK-E-0.5M is offered new sealed and certified refurbished. Certified refurbished cables have connectors, pins, latches and housing inspected, connected between two compatible switches, and stack link up at the rated bandwidth. Order one cable per member for a full ring, or one fewer cable for a chain; measure rear-port spacing. New warranty is up to 3-year extended, certified refurbished warranty is up to 1 year, and returns are 30 days on every condition; terms apply. Regional stock and RMA cover UK, EU, US and MEA, with RMA with advance replacement, PO accepted and Net-30 for government.

A buyer has a failed rear FlexStack link in an existing stack and needs the same 0.5 m reach. The replacement cable must match the STACK 1 and STACK 2 path already in place, and the PO should count one cable for each failed link.
A buyer has a chain where one closing FlexStack link is missing, leaving half bandwidth and no redundant connection. A full ring needs one cable per switch, so a 4-member stack needs 4 cables and the PO should cover the missing link.
A buyer is building a short stack with switches directly above each other in a rack or on a table. The 0.5 m cable is the measured reach to verify, and the PO should count 2 cables for a 2-switch full ring.
Spaced rear stack ports
CAB-STK-E-0.5M is limited to 0.5 m links; use CAB-STK-E-1M for 1 m or CAB-STK-E-3M for 3 m between rear stack ports.
2960-XR mixed stack
CAB-STK-E-0.5M does not make Catalyst 2960-XR stack with Catalyst 2960-X or Catalyst 2960-S. The mixed mode is Catalyst 2960-X LAN Base with Catalyst 2960-S/SF LAN Base.
Long-distance fiber links
CAB-STK-E-0.5M uses the copper FlexStack port, not the SFP+ fiber port. FlexStack-Extended distance links use C2960X-FIBER-STK with SFP+ ports and optics.

CAB-STK-E-0.5M is the Cisco FlexStack 50cm stacking cable for 0.5 m rear stack links. The cable is a data stack cable, not a power cable or module. It serves FlexStack, FlexStack-Plus and FlexStack-Extended hybrid copper stack ports on named Catalyst access switches.
CAB-STK-E-0.5M fits stack-capable Catalyst 2960-XR, Catalyst 2960-X LAN Base, Catalyst 2960-S and Catalyst 2960-SF stacks. Catalyst 2960-XR does not mix with 2960-X or 2960-S. LAN Lite models and WS-C2960X-24PSQ-L do not take this cable. Catalyst 2960-S does not stack with 2975, 3550, 3560 or 3750 switches.
A Catalyst 2960-X uses CAB-STK-E-0.5M, CAB-STK-E-1M or CAB-STK-E-3M FlexStack cables on FlexStack-Plus modules. C2960X-STACK supplies the copper module, and C2960X-HYBRID-STK supplies one copper FlexStack-Plus port plus one SFP+ fiber port. Use length to match rear-port spacing.
CAB-STK-E-0.5M provides FlexStack at 20 Gbps, FlexStack-Plus at 80 Gbps and FlexStack-Extended copper hybrid links at 40 Gbps. The stack acts as one switching unit with a unified data plane, unified configuration and one management IP address. A complete ring keeps redundant connections.
A full-ring stack needs one CAB-STK-E-0.5M per switch, so 4 switches need 4 cables. A chain uses one fewer cable, so 4 switches use 3 cables. Choose 0.5 m only when adjacent rear stack ports reach without strain.
CAB-STK-E-0.5M stacks have 8 members on Catalyst 2960-XR or 2960-X FlexStack-Plus, 8 members on FlexStack-Extended, and 4 members on Catalyst 2960-S/SF FlexStack. A full ring gives full bandwidth and redundant connections. A half ring has half bandwidth and no redundant connection.
CAB-STK-E-0.5M inserts between rear stack ports until the connector snaps into place. STACK 1 uses the connector tab above the port, and STACK 2 uses the tab below the port. Power off a switch before adding it to or removing it from an existing stack.
CAB-STK-E-0.5M can be used in a Catalyst 2960-X LAN Base and Catalyst 2960-S/SF LAN Base mixed stack at 40 Gbps with 4 members. Catalyst 2960-XR does not join that mixed stack. The Catalyst 2960-X stack speed must be set to 40 for the mix.
CAB-STK-E-0.5M needs Cisco IOS 15.2(6)E or later for FlexStack-Extended use with the fiber or hybrid modules. FlexStack-Plus and FlexStack copper modules use the stack software already running on the member switches, and new members join the stack software version.
CAB-STK-E-0.5M= is the spare ordering form for the 0.5 m FlexStack cable, while CAB-STK-E-0.5M is the base PID. The equals sign does not change the 0.5 m length or FlexStack role. Certified refurbished condition is separate from any Cisco spare-form PID.
CAB-STK-E-0.5M is the 0.5 m FlexStack cable for adjacent stack ports, while CAB-STK-E-1M is the 1 m length for wider spacing. Both serve the same FlexStack cable family. Choose the 0.5 m cable for close switches and the 1 m cable when rear ports do not reach.
CAB-STK-E-0.5M is the 0.5 m FlexStack cable, while C2960X-STACK is the FlexStack-Plus hot-swappable stacking module for Catalyst 2960-X switches. Each stack-capable 2960-X switch needs the module, and the module still needs FlexStack cables for the links between switches.
Cisco stopped selling CAB-STK-E-0.5M on 31 October 2022. Cisco service ends on 31 October 2027 for the Catalyst 2960X Product Family. The cable serves Catalyst 2960-XR, Catalyst 2960-X, Catalyst 2960-S and Catalyst 2960-SF stacks named for this FlexStack cable family.
ORM offers CAB-STK-E-0.5M new sealed with up to 3-year extended warranty and certified refurbished with up to 1 year warranty. Returns are 30 days on every condition; terms apply. Cisco service ends 31 October 2027, so Cisco service remains dated separately from ORM's cover.
