7.5 Power Adaptor Card Installation
The upper right of the MS-7206’s front panel contains two slots for MPC-7202 PoE power
adaptor cards. A MPC-7202 power adaptor card sends power from a MP-7202 power injector,
through the back plane to PoE interface modules like the MI-7248PWR.
• You need one MP-7202 power injector for each PoE interface module.
• One power adaptor card can connect up to two MP-7202 power injectors to PoE interface
modules.
• Install the MP-7202 power injector(s) above the MS-7206 in the rack.
• Connect MP-7202s to a power adaptor card in the left slot to power PoE interface modules
in slots 3 and/or 4.
• Connect MP-7202s to a power adaptor card in the right slot to power PoE interface
modules in slots 5 and/or 6.
• Leave the slot covers on unused slots.
Refer to the following graphic and instructions to install power adaptor cards.
1 Grasp the center of the front panel of the power adaptor card with one hand and place
your other hand under the power adaptor card to support it.
2 Slide the power adaptor card into the slot until it makes contact with the backplane.
3 Use a screwdriver to tighten the two screws.
