STACK-CAB-1M is a Cisco 1M Stacking Cable, a 1 m StackWise stack cable for Catalyst 2975 switches at 32 Gbps. Its edge is the middle cable length for Catalyst 2975 stacks, between the 0.5 m and 3 m options. The fit is Catalyst 2975 stack ports. This Cisco Catalyst 2975 stack cable links the high-speed stacking ports on each WS-C2975GS-48PS-L switch. A StackWise stack gives one configuration file, one IP address, and master and backup master roles. The 0.5 m cable suits adjacent units in the same rack. STACK-CAB-3M suits wider spacing; this 1 m StackWise cable keeps shorter runs between separated switches.

32 Gbps of StackWise bandwidth applies when the Catalyst 2975 ring is closed. A full ring of 4 switches needs 4 data stack cables; a chain needs 3 and loses the redundant path. STACK-CAB-1M uses the dedicated stack ports, not Ethernet or SFP uplink ports. Catalyst 2975 stacks support up to 9 members with member numbers 1 to 9. Master election uses stack priority, software image priority, and the lowest MAC address after the current master role. A single cable fault leaves a half-bandwidth connection until the ring is restored. All stack members must run the same Cisco IOS software version for stack protocol alignment.
STACK-CAB-1M is offered new sealed and certified refurbished. Certified refurbished units have connectors, pins, latches and housing inspected, then stack link up at the rated bandwidth between two compatible switches. Cisco service ended on 30 April 2022, so ORM's warranty is the cover that applies. Order 1 cable per stack member for a full ring and verify the 1 m path before the PO. Warranty is new — up to 3-year extended and certified refurbished — up to 1 year, with 30 days on every condition; terms apply. Regional stock/RMA: UK, EU, US and MEA; PO accepted, Net-30 for government and RMA with advance replacement.

An owner of installed Catalyst 2975 stacks needs sparing after Cisco service ended on 30 April 2022. The spare pool needs the same StackWise length already cabled in the ring. Count each 1 m cable position and order the matching replacement before the PO.
A failed stack link in a Catalyst 2975 ring leaves the stack on the remaining path at half bandwidth. The replacement must match the 1 m StackWise cable path and the dedicated stack ports. Count the failed link, inspect both connectors, and order one cable before the PO.
A stack expansion from 3 to 4 Catalyst 2975 switches needs the ring closed after the new member is added. A full ring uses 1 data stack cable per member. Count 4 cables for 4 switches and measure the return path before the PO.
Catalyst 3750 stack ports
Catalyst 3750 StackWise ports use CAB-STACK-1M for the 1 m cable. STACK-CAB-1M is a Catalyst 2975 cable, so the equal length does not make the port fit.
Three-metre switch spacing
A 3 m Catalyst 2975 path needs STACK-CAB-3M. STACK-CAB-1M gives a 1 m path, so it does not reach switches separated beyond that cable length.
Non-halogen material requirement
A non-halogen 1 m Catalyst 2975 cable uses STACK-CAB-1M-NH. STACK-CAB-1M is the standard 1 m cable and does not add that material designation.

STACK-CAB-1M is the Cisco 1M Stacking Cable for Catalyst 2975 StackWise stacks. The 1M segment marks the 1 m length, and STACK-CAB marks the Catalyst 2975 stacking-cable family. The cable carries the stack link between dedicated stack ports at 32 Gbps.
STACK-CAB-1M fits Catalyst 2975 switches, with the WS-C2975GS-48PS-L model using high-speed stacking ports. Catalyst 3750 uses CAB-STACK-1M for a 1 m StackWise cable. Equal length does not mean the same stack-port fit. Match the cable family before matching the length.
A Catalyst 2975 uses STACK-CAB-1M for a 1 m stack cable. The same Catalyst 2975 ordering set also has STACK-CAB-50CM for 0.5 m runs and STACK-CAB-3M for 3 m runs. Match the cable length to the measured stack-port path.
STACK-CAB-1M carries Catalyst 2975 StackWise at 32 Gbps when the ring is complete. The StackWise stack gives one IP address, one configuration file, master and backup master roles, and automatic member provisioning. A broken single link leaves the stack on a half-bandwidth path.
A full Catalyst 2975 ring needs 1 STACK-CAB-1M per stack member when every cable path measures 1 m or less. A 4-switch ring needs 4 cables, and a chain needs 3. The missing return link removes the redundant ring path.
A Catalyst 2975 stack using STACK-CAB-1M can have up to 9 members. Member numbers run from 1 to 9, and the ring operates at full 32 Gbps bandwidth when both stack paths are closed. A single cable fault leaves half bandwidth until the ring is restored.
Install STACK-CAB-1M between the dedicated stack ports on Catalyst 2975 switches, not between Ethernet or SFP uplink ports. Power off a switch before adding that member to an existing stack. After cabling, check that the stack ring reports full 32 Gbps bandwidth.
STACK-CAB-1M= is the spare form of STACK-CAB-1M for the Cisco 1M Stacking Cable. The fit, length and StackWise role are the same for Catalyst 2975 stacks. The equals sign is an ordering-form suffix, not a separate cable length or a refurb condition.
STACK-CAB-1M is the 1 m Catalyst 2975 stack cable, and STACK-CAB-3M is the 3 m Catalyst 2975 stack cable. Both serve the same StackWise stack ports and 32 Gbps stack technology. Choose 1 m for shorter measured paths and 3 m for wider spacing.
STACK-CAB-1M gives a 1 m Catalyst 2975 StackWise path, while STACK-CAB-50CM gives a 0.5 m path for adjacent switches. Both cables serve the same dedicated stack ports. Choose the 0.5 m cable for tight rack positions and 1 m for more separation.
STACK-CAB-1M is the 1 m stacking cable for Catalyst 2975. CAB-STACK-1M is the 1 m StackWise cable used by Catalyst 3750 stack ports. Equal length does not make the connectors or stack-port family interchangeable, so match the PID to the switch family.
Cisco stopped selling STACK-CAB-1M on 30 April 2017. Cisco service ended on 30 April 2022 for the affected accessories set that carries this PID. The cable serves Catalyst 2975 stacks, and Catalyst 2975 is a retired switch family. No replacement product was named for this PID set.
ORM offers STACK-CAB-1M new sealed and certified refurbished. Certified refurbished cables are inspected and bench-tested between two compatible switches. Cisco service ended on 30 April 2022, so ORM's warranty is the cover that applies: new — up to 3-year extended and certified refurbished — up to 1 year. Returns are 30 days on every condition; terms apply.
