Workaround
The correct workaround depends on the Cisco switch platform that the DMP is

If there is ample PoE power available in the switch‟s
power budget, apply the power inline static max 15401 interface-level
command to each access switch port connected to a DMP-4310.

The
use of “power inline static max 15401” command requires “power inline port
max 15401” be configured first.
On an ePoE-capable switch platform, specifying a maximum power level greater
than the 802.3af maximum of 15.4W has a side effect of causing the switch port
to bypass the optional power class negotiation phase.

to bypass the optional power class negotiation phase.
The use of the static keyword is suggested in order to reserve the required
power from the switch‟s power budget at configuration time. If for some reason
the switch‟s remaining power budget cannot accommodate the port‟s configured
power requirement, the port is placed into error disable state at point of
configuration, rather than point of need.

Non-ePoE Capable Platforms
– Because non-ePoE capable switch platforms
cannot be configured to deliver more than the 802.3af maximum of 15.4W/port,
the suggested workaround is to insert a PoE splitter between the switch port and
the DMP 4310G. Generally, a PoE splitter is used to strip the PoE power from a

PoE-capable switch port and provide it to a non-
PoE capable device in lieu of it‟s
usual “power brick”. In this case, the PoE splitter is used to circumvent the DMP
4310G PoE class negotiation issue, since the PoE splitter does not attempt to
negotiate the PoE class with the switch and simply passes through the available
power it receives over the cable run.

DMP Reboot Behaviour
If you reboot a DMP during an event script, expect the following behavior:
If the event is not running or the event script does not control the DMP, you will
be brought back to full screen video of defaultVideoUrl from the registry.
If the DMP is controlled by the event script, then you should see the following
behavior:
During the reboot, you will lose all video / templates / etc.
After the reboot has recovered, the DMP will take a few seconds to recover.
After recovery has completed, you should see the template from the script.
(Full screen / 3 region / etc.), and the non-video playlists will be correct.
