Power Supply Modules Overview
The switch operates with either one or two active power supply modules. A switch that is part of a StackPower
stack operates with power that is supplied by other stack switches.
You can use two AC modules or one module and blank cover. All power supply modules have internal fans.
All switches ship with a blank cover in the second power supply slot.
The following table describes the supported internal power supply modules. It lists the Platinum certified
power supply modules and the default modules that are shipped with the switch. In a switch, a mix of Platinum
certified and non-Platinum certified power supply modules is supported.

Installing a Power Supply Installing a DC Power Supply Installing a DC Power Supply Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122 Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. -
Page 9: Grounding The Switch
Installing a Power Supply Grounding the Switch • Four fork-type terminals from the DC power supply accessory kit. The terminals must be the proper size for M3 screws in a Dinkle DT-35-B25-style terminal block. • M5 screws for 12 AWG wire connection for NEBS installations. Grounding the Switch Follow these steps to install either a single-hole ground lug or a dual-hole ground lug on the switch. - Page 10 Installing a Power Supply Grounding the Switch Figure 7: Stripping the Ground Wire Step 3 Slide the open end of the ground lug over the exposed area of the wire. Step 4 Using a Panduit crimping tool, crimp the ground lug to the wire. Figure 8: Crimping the Ground Lug Step 5 Use the ground screw to attach the single-hole ground lug to the switch rear panel.
