DMPs use electrical power to run. Your DMP model and geographic locale might both affect which
power plug your DMP uses.

DMP 4310G Notice Regarding Power over Ethernet (PoE)

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.
