STACK-CAB-50CM is the Cisco 50CM Stacking Cable, a 0.5 m StackWise stack cable for Catalyst 2975 switches with 32 Gbps stack bandwidth. The 0.5 m length is the edge over STACK-CAB-1M when adjacent switches need less cable slack. This 0.5 m cable stacks Catalyst 2975 switches, and same-length Catalyst 3750 StackWise runs take CAB-STACK-50CM instead. As a Cisco Catalyst 2975 stack cable, it belongs with the dedicated stacking ports on that switch family. Dedicated stacking ports and special stacking cables form the single stack. StackWise gives the buyer one IP address, one configuration file, master and backup master roles, and up to 9 members.

32 Gbps of stack bandwidth links the Catalyst 2975 members through StackWise. 0.5 m of cable reach suits adjacent switches in the same rack, while the 1 m and 3 m stack cables cover longer paths. 9 switches is the Catalyst 2975 StackWise member limit. Full-ring cabling keeps redundant StackWise connections, and an incomplete cable path runs at half bandwidth without redundant connections. STACK-CAB-50CM carries data stacking only and does not carry StackPower or RPS power. The cable has no module slot, no stack-port count of its own, and no uplink role. The Cisco 50CM Stacking Cable is a replacement part for the cable link, not a switch or stack adapter.
STACK-CAB-50CM is offered new sealed and certified refurbished. Certified refurbished testing checks connectors, pins, latches and housing inspected, connected between two compatible switches, and stack link up at the rated bandwidth. Confirm 0.5 m reach before the PO; a full ring needs one cable per Catalyst 2975 member. Cisco service ended on 30 April 2022, so ORM's warranty is the cover that applies. New warranty is up to 3-year extended; certified refurbished is up to 1 year; returns are 30 days on every condition, terms apply. Regional stock and RMA with advance replacement cover UK, EU, US and MEA; PO accepted and Net-30 for government apply.

The buyer is maintaining Catalyst 2975 access stacks after Cisco service ended on 30 April 2022. STACK-CAB-50CM replaces a failed 0.5 m link without changing the stack technology. Count one cable for each ring link before the PO.
The buyer has a Catalyst 2975 stack with one damaged short cable and needs the same 0.5 m StackWise reach. STACK-CAB-50CM matches the original adjacent-switch length. Measure the rack path and order one cable for each failed link.
The buyer is closing a Catalyst 2975 StackWise ring after a chain build. A full ring uses one cable per member and keeps redundant StackWise connections. Count the stack members, confirm 0.5 m reach between neighbors, and match every open ring link.
Catalyst 3750 stack ports
STACK-CAB-50CM fits Catalyst 2975 StackWise ports. Catalyst 3750 StackWise ports take CAB-STACK-50CM for the same 0.5 m reach because the cable families differ.
Longer rack spacing
STACK-CAB-50CM is 0.5 m. Spaced switches need STACK-CAB-1M or STACK-CAB-3M when the cable path exceeds adjacent-switch reach before ring completion.
Non-halogen material requirement
STACK-CAB-50CM is the standard 0.5 m cable. A non-halogen lead-free requirement points to STACK-CAB-50CM-NH for the same Catalyst 2975 length.

STACK-CAB-50CM is the Cisco 50CM Stacking Cable for Catalyst 2975 StackWise stacks. The STACK-CAB segment identifies the Catalyst 2975 stack-cable family, and 50CM marks the 0.5 m length. The cable carries 32 Gbps stack bandwidth between dedicated StackWise ports.
STACK-CAB-50CM fits Catalyst 2975 switches. It does not fit Catalyst 3750 StackWise ports; Catalyst 3750 uses CAB-STACK-50CM for the same 0.5 m reach. Same length does not mean the same stack-cable family, so match the switch family before replacing a failed link.
A Catalyst 2975 uses STACK-CAB-50CM for 0.5 m StackWise links. The same Catalyst 2975 cable family also has 1 m and 3 m lengths, plus non-halogen lead-free versions. Match the required run length and keep every cable in the Catalyst 2975 StackWise family.
STACK-CAB-50CM carries the Catalyst 2975 StackWise stack bandwidth of 32 Gbps. StackWise presents the stack through one IP address and one configuration file, with master and backup master roles inside the stack. An incomplete cable path runs at half bandwidth and loses redundant connections.
A Catalyst 2975 full ring needs one STACK-CAB-50CM cable per stack member when every adjacent link uses 0.5 m reach. A chain needs one fewer cable than the member count. Count the switches first, then confirm each neighbor-to-neighbor path fits 0.5 m.
STACK-CAB-50CM serves Catalyst 2975 StackWise stacks of up to 9 switches. A full ring keeps redundant stack connections, while an incomplete cable path runs at half bandwidth and loses redundant connections. Count the members and cable every ring link before adding the last switch.
STACK-CAB-50CM connects between the dedicated StackWise ports on two Catalyst 2975 switches. Seat each end in the StackWise port and secure the cable screws. Use Cisco-approved StackWise cabling for this stack technology, then check the stack LEDs and stack-member view.
No Cisco replacement PID was given for STACK-CAB-50CM. Cisco stopped selling the cable on 30 April 2017, and Cisco service ended on 30 April 2022. If the stack remains Catalyst 2975, match the same cable family, length, and material requirement before ordering.
STACK-CAB-50CM is the 0.5 m Catalyst 2975 StackWise cable, and STACK-CAB-1M is the 1 m Catalyst 2975 StackWise cable. Choose STACK-CAB-50CM for adjacent switches with short rear cable paths. Choose STACK-CAB-1M when the rack spacing needs more reach.
STACK-CAB-50CM gives 0.5 m of Catalyst 2975 StackWise reach, while STACK-CAB-3M gives 3 m of reach in the same cable family. Use the 0.5 m cable for adjacent members. Use the 3 m cable for longer rack paths that still use Catalyst 2975 StackWise.
STACK-CAB-50CM is the standard 0.5 m Catalyst 2975 stack cable, and STACK-CAB-50CM-NH is the non-halogen lead-free 0.5 m version. The fit and length match the same Catalyst 2975 StackWise family. Choose the NH part when the site requires that cable material.
Cisco stopped selling STACK-CAB-50CM on 30 April 2017. Cisco service ended on 30 April 2022 for the affected stack accessories, and Cisco has retired the Catalyst 2975 and no longer supports it. The cable is a post-support spare for installed Catalyst 2975 stacks.
ORM supplies STACK-CAB-50CM new sealed or certified refurbished, with new warranty up to 3-year extended and certified refurbished warranty up to 1 year. Cisco service ended on 30 April 2022, so ORM's warranty is the cover that applies. Returns are 30 days on every condition, terms apply.
