MA-CBL-SPWR-150CM is the Meraki MS390 150CM StackPower Cable, a 1.5 m StackPower cable for MS390 switches. The 1.5 m reach separates it from MA-CBL-SPWR-30CM for spaced chassis. It carries power sharing, not data traffic. This Cisco Meraki MS390 stack cable fits all MS390 models and uses the rear StackPower ports. StackPower pools input power across a full ring of up to 4 switches in power-sharing mode. The Meraki StackPower cable gives the stack a common power pool for PoE loads. MS390 data stacking remains a separate 120G cable plan, so the buyer matches power and data cables before the PO.

1.5 m of cable length gives reach for MS390 switches that are not adjacent in the rack. 4 switches is the power-stack limit, and an 8-switch data stack can be split into more than one StackPower setup. Full-ring topology treats all input power as one large supply for switch and PoE loads. MA-CBL-SPWR-150CM connects between rear StackPower ports, with the green-banded end on the first switch and the yellow-banded end on the next switch. Hand-tightened captive screws secure the connectors. StackPower ports have no data bandwidth figure. MS390 StackPower runs on MS/CS 15 or later and needs no dashboard configuration after the cabling is installed.
MA-CBL-SPWR-150CM is offered new sealed and certified refurbished. Certified refurbished units have connectors, pins, latches and housing inspected, and power sharing forms between the two switches. Confirm 1.5 m reach and count one StackPower cable per switch for a full ring of up to 4 switches. Cisco stopped selling this PID on 29 October 2026, and Cisco service ends on 31 October 2031. New carries up to 3-year extended warranty; certified refurbished carries up to 1 year. Returns are 30 days on every condition; terms apply. Regional stock/RMA covers UK, EU, US and MEA; RMA with advance replacement applies; PO accepted and Net-30 for government.

The buyer has a damaged 1.5 m StackPower link between MS390 switches. The replacement must match the StackPower ports rather than the data stack ports, because power sharing and data stacking use separate cables. Measure the path and order one cable for each failed link before the PO.
The buyer is building a four-switch MS390 power stack. StackPower uses ring topology with up to 4 switches, so the plan needs a closed cable path and one 1.5 m cable for each switch when the chassis spacing needs that reach. Count the members before the PO.
The buyer maintains MS390 access stacks after Cisco's 29 October 2026 sales stop. A spare cable pool keeps a power-sharing repair from becoming a cable-length mismatch. Separate 0.3 m and 1.5 m spare positions, then order the 1.5 m count before the PO.
Data stack bandwidth
MA-CBL-SPWR-150CM carries StackPower only and has no data bandwidth. MS390 data stacking uses 120G stack cables; choose MA-CBL-120G-1M for a 1 m data-stack link.
Adjacent chassis reach
MA-CBL-SPWR-150CM is 1.5 m for spaced chassis. Adjacent MS390 switches needing the shorter StackPower lead use MA-CBL-SPWR-30CM at 0.3 m.
Non-MS390 StackPower ports
MA-CBL-SPWR-150CM fits MS390 only. C9300, C9300X, C9300S and C9350 StackPower ports need the StackPower cable assigned to that switch family.

MA-CBL-SPWR-150CM is the Cisco Meraki MS390 Power-Stack Cable, 150 centimeter, also named the Meraki MS390 150CM StackPower Cable. It is a 1.5 m StackPower cable for MS390 power sharing. SPWR identifies StackPower, and 150CM identifies the 150 cm cable length.
MA-CBL-SPWR-150CM fits MS390 switches, and all MS390 models take this StackPower cable. The fit is the rear StackPower port, not the rear data stack port. A buyer with Catalyst or another Meraki family must match that switch family’s own StackPower accessory before ordering.
MS390 uses MA-CBL-SPWR-150CM for 1.5 m StackPower links and MA-CBL-SPWR-30CM for 0.3 m StackPower links. MS390 data stacking is separate and uses the Meraki 120G stacking cable family. Match the StackPower length to the chassis spacing and keep data-stack cables on the data stack ports.
MA-CBL-SPWR-150CM forms a StackPower link that pools and distributes input power across MS390 switches. The edge is the 1.5 m reach for spaced chassis. StackPower runs in power-sharing mode, treats the available input power as one pool and has no data bandwidth figure.
A full MS390 StackPower ring needs one cable per switch, with a maximum of 4 switches in one power stack. A four-switch ring needs 4 cables when every link needs 1.5 m reach. More than 4 data-stack members require more than one StackPower setup.
MA-CBL-SPWR-150CM uses StackPower ring topology on MS390. The power stack is limited to 4 switches, while an MS390 data stack can have up to 8 switches. A larger data stack must be divided into separate StackPower power stacks for power sharing.
MA-CBL-SPWR-150CM installs in the rear StackPower ports on MS390. The green-banded end connects to either StackPower port on the first switch, and the yellow-banded end connects to another switch. The captive screws are hand-tightened, and StackPower needs no dashboard configuration after cabling.
MS390 StackPower needs MS/CS 15 or later for the StackPower feature. MA-CBL-SPWR-150CM is a cable, so the firmware requirement belongs to the MS390 power-stack feature rather than the cable body. The Dashboard automatically enables power-sharing mode after correct StackPower cabling.
MA-CBL-SPWR-150CM is the 1.5 m MS390 StackPower cable, while MA-CBL-SPWR-30CM is the 0.3 m MS390 StackPower cable. Both fit MS390 StackPower ports and carry power sharing only. Choose the 1.5 m cable for spaced chassis and the 0.3 m cable for adjacent chassis.
MA-CBL-SPWR-150CM is a StackPower cable for power sharing, while MA-CBL-120G-1M is a 1 m MS390 120G data-stack cable. The StackPower cable has no data bandwidth figure. Choose the StackPower cable for power pooling and the 120G cable for MS390 data stacking.
Cisco stopped selling MA-CBL-SPWR-150CM on 29 October 2026. Cisco service ends on 31 October 2031 for this cable, and no replacement PID is provided. Cisco stopped selling the MS390 Series on 28 March 2025, and Cisco service ends on 28 March 2032.
