The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

DMPs use electrical power to run. Your DMP model and geographic locale might both affect which power plug your DMP uses.
Starting in 2009, a handful of Cisco StadiumVision customers participated in a special program to receive DMP 4310G endpoints whose hardware design was not yet utterly final. During this limited, pre-release program, we manufactured such units under the Cisco product ID "DMP-4310G-SE-K9." Partway through the limited release, we changed one physical component in the hardware design to improve the Power over Ethernet (PoE) performance of a DMP 4310G.
Is even one of these statements true for you?
When even one of these statements is true, your DMP 4310G uses the improved PoE component. Nothing further about this topic applies to you or your DMP.
Otherwise, when even one statement is false, your DMP 4310G uses the original PoE component. We have identified a corner case in which these DMPs might not receive full PoE power. Suppose that a very long Ethernet cable connects the DMP 4310G to a network switch from the Cisco 3560 Series. And suppose also that the Ethernet cable length is so great that the level of PoE power becomes noticeably diminished after traveling its full distance to the DMP. In this scenario, your DMP cannot compensate for the degraded power because switches in the Cisco 3560 Series do not permit adjustments to their PoE power output.
We recommend that you do not obtain power for such DMPs from network switches in the Cisco 3560 Series. When you must do so, then take care to use the shortest possible Ethernet cord. Alternatively, you might use network switches from the Cisco 3750 Series, which offer configurable PoE power output.
Warning Use ONLY the power adapter, power cord, and plugs that we supply for your DMP model explicitly.
DO NOT USE OTHERS, even if they appear identical or appear to work with another DMP model.
Step 1 If your DMP power cord must be assembled, assemble it.
a. Identify the correct snap-on plug for your region.
b. Snap that plug onto the AC adapter.
Step 2 Connect the DMP power cable to the AC adapter.
Step 3 Connect the DC barrel connector to the DC power supply on the DMP chassis.
Step 4 Connect to an AC electrical outlet that you know is grounded. It must use the correct voltage level for your locale. Supported levels range from 100V to 240V.
Note To protect your DMP from electrical surges, we recommend that you use a surge protector or an uninterruptable power supply from a reputable manufacturer.
Step 5 Stop. You have completed this procedure.
Note ● You can power a DMP 4310G through its Ethernet cable. Other DMP models do not support this feature.
Step 1 Use the On/Off power button on the DMP chassis to verify that your DMP is turned Off.
Step 2 Connect a standard, Category 5 Ethernet cable to your DMP.
Step 3 Attach the other end of the Ethernet cable to a PoE-enabled network switch that operates inside your network.
Step 4 Use the On/Off power switch on the DMP chassis to turn your DMP On.
Step 5 Stop. You have completed this procedure.
