Cisco Meraki MA-CBL-SPWR-150CM MS390 Series 1.5m StackPower Cable

The Cisco Meraki MA-CBL-SPWR-150CM is a 150cm (59.1-inch) StackPower cable for Meraki MS390 switches. StackPower joins the power supplies of the switches in a stack into one shared pool, so a switch that loses a power supply can draw from its neighbors, and spare capacity can feed PoE where it is needed.

StackPower is separate from data stacking. Data stacking joins the switches into one logical switch over their 120G stacking cables, while StackPower cables join only their power. A closet can use both at once, and each StackPower cable is run between two switches in the stack.

The 150cm length reaches across a tall stack or between switches that are spaced apart, and it is the usual choice for closing a power ring from the bottom switch back to the top. For switches mounted directly above each other, the 30cm MA-CBL-SPWR-30CM is the shorter option. This listing is for one cable; switches and power supplies are sold separately.

The cable fits all MS390 models, including the MS390-48P-HW 48-port PoE+ switch. For the data stack, see the MA-CBL-120G-1M 1m stacking cable. It is a passive cable with no configuration.

This seller refurbished Cisco Meraki MA-CBL-SPWR-150CM StackPower cable is tested, working, and covered by the NetworkTigers one-year warranty.
