MA-CBL-40G-50CM is a Stack Cable for the Meraki 40GbE QSFP Cable, 0.5 Meter, a 40 Gbps Meraki Stacking passive Twinax cable for MS425 switches. The 0.5 m reach is its edge over the 1 m and 3 m cables when adjacent stack members share the same rack. This Meraki MS stack cable fits MS425, MS410, MS350, MS250, MS225 and MS210 switches. The cable uses dedicated stack ports on MS210, MS225, MS250, MS350 and MS410, and configured front QSFP+ stack ports on MS425. MS210 and MS225 can share one stack; the other named families stack only with like models. A full ring closes the path from the bottom switch to the top switch.
MA-CBL-40G-50CM price is $101.85, a 26.7% saving from the Cisco list price of $138.92. MA-CBL-40G-50CM is in stock and available for free next-day delivery. (terms applied)

40 Gbps data rate matches the 40GQSFP+Cu Meraki Stacking cable class used by MS210, MS225, MS250, MS350, MS410 and MS425 switches. 0.5 m length serves adjacent members, and the other available lengths in the same family are 1 m and 3 m. Eight switches can form one physical or flexible stack when the model rules allow the members. Full-ring cabling uses one cable per switch; a four-switch full ring needs four cables. MA-CBL-40G-50CM uses a QSFP+ passive Twinax cable assembly with no stack module, slot count or power-sharing role. Initial physical stack builds use powered-off switches and disconnected links before the ring is cabled.
MA-CBL-40G-50CM is offered in new sealed and certified refurbished conditions. Certified refurbished units have connectors, pins, latches and housing inspected, then are connected between two compatible switches with the stack link up at the rated bandwidth. Confirm the measured 0.5 m path and the full-ring cable count before the PO. New sealed carries up to 3-year extended warranty, and certified refurbished carries 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 buyers; PO accepted and Net-30 for government apply.

A buyer replacing one failed 40 Gbps QSFP+ stack link keeps the same Meraki Stacking cable class and the same 0.5 m reach. The stack model must be MS210, MS225, MS250, MS350, MS410 or MS425, and the replacement count is one cable per failed link before the PO.
A buyer building a rack-local full ring counts one cable per stack member. A four-switch full ring needs four 0.5 m cables when every cable path is within 0.5 m. The PO must match the stack family, member count and measured rear or front-port path.
A buyer combining MS210 and MS225 switches can build one shared stack with the 40 Gbps Meraki Stacking cable class. The same exception does not extend to MS250, MS350, MS410 or MS425. Count every member for a full ring before the PO.
100 Gigabit Meraki stack
MA-CBL-40G-50CM is a 40 Gigabit cable for MS210, MS225, MS250, MS350, MS410 and MS425. MS150, MS355 and MS450 take MA-CBL-100G-50CM instead.
MS390 data stack
MS390 uses 120 Gigabit Meraki Stacking, so MA-CBL-40G-50CM does not fit that stack. Order MA-CBL-120G-50CM for a 0.5 m MS390 link.
Cross-family stack mix
MS250 does not stack with MS350; only like-model stacks are allowed, except MS210 with MS225. Match the cable to a valid family stack.

MA-CBL-40G-50CM is the Cisco Meraki 40GbE QSFP Cable, 0.5 Meter. It is a 40GQSFP+Cu Meraki Stacking cable with a QSFP+ passive Twinax cable assembly, 0.5 m length and 40 Gbps data rate for Meraki MS stack links.
MA-CBL-40G-50CM fits MS210, MS225, MS250, MS350, MS410 and MS425 switches. MS210 and MS225 can share one stack; the other named families stack only with like models. MS150, MS355 and MS450 use MA-CBL-100G-50CM for 0.5 m 100 Gigabit Meraki Stacking.
A Meraki MS425 uses MA-CBL-40G-50CM, MA-CBL-40G-1M or MA-CBL-40G-3M for the 40 Gigabit Meraki Stacking cable class. MS425 flexible stacking uses front ports configured as stack ports, and the 0.5 m cable suits adjacent members in the same rack.
MA-CBL-40G-50CM carries a 40 Gbps data rate in the Meraki Stacking cable class. The cable is a 40GQSFP+Cu passive Twinax assembly. MS210, MS225, MS250, MS350, MS410 and MS425 stacks use that 40 Gigabit cable class, with full-ring topology for redundancy.
A full ring needs one MA-CBL-40G-50CM cable per stack member when every cable path is within 0.5 m. Two switches need two cables, four switches need four cables, and eight switches need eight cables. A chain uses one fewer cable and leaves an open path.
MA-CBL-40G-50CM serves Meraki switch stacks of up to eight members. The model rules still control the members: MS210 can stack with MS225, but MS250 cannot stack with MS350. MS425 uses flexible stacking, while MS210, MS225, MS250, MS350 and MS410 use dedicated stack ports.
MA-CBL-40G-50CM is installed with powered-off switches and disconnected links for an initial physical stack build. The connector must align with the stack port, the screws must be finger-tightened, and stack LEDs move from cable-detected status to good stack status when the link forms.
MA-CBL-40G-50CM can be used in a stack that mixes MS210 and MS225 switches. That exception is limited to those two families. MS250, MS350, MS410 and MS425 follow like-model stacking, so the same cable does not override a family mismatch.
MA-CBL-40G-50CM is the 0.5 m cable, while MA-CBL-40G-1M is the 1 m cable in the same 40GQSFP+Cu Meraki Stacking family. Both serve the same 40 Gigabit switch families. Choose the 0.5 m cable for adjacent members and 1 m for a longer measured path.
MA-CBL-40G-50CM serves 40 Gigabit Meraki Stacking for MS210, MS225, MS250, MS350, MS410 and MS425. MA-CBL-100G-50CM serves 100 Gigabit Meraki Stacking for MS150, MS355 and MS450. Both are 0.5 m passive Twinax cables, but the switch families and data rates differ.
MA-CBL-40G-50CM is the 40 Gigabit cable for MS210, MS225, MS250, MS350, MS410 and MS425. MA-CBL-120G-50CM is the 120 Gigabit stack cable for MS390 and C9300 stacks. Choose by switch family first, then match the 0.5 m cable length.
Cisco stopped selling MA-CBL-40G-50CM on 29 October 2026. Cisco service ends on 31 October 2031 for the legacy switching accessory, and Cisco named no replacement available at that time. The cable serves MS210, MS225, MS250, MS350, MS410 and MS425 stacks.
ORM offers MA-CBL-40G-50CM new sealed and certified refurbished. New sealed 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 Meraki accessories carry 1 year, and Cisco service ends on 31 October 2031.
