Logical Port FAQs
Q.
Which logical ports on my DMPs should my firewall ever allow?
A.
As of November 2010, these are the only ports that a DMP might ever use.
Power-over-Ethernet FAQs
Q.
What will happen if I try to use AC power and PoE simultaneously on a DMP?
A.
When both PoE power and AC power are detected, AC power overrides PoE and disconnects the
PoE circuit.
Q.
Does my use of PoE affect the operation of any other DMP feature?
A.
A DMP 4310G has two USB interfaces on its chassis. When you use PoE to power a DMP 4310G,
we recommend that you use no more than one of these USB interfaces at a time. IEEE 802.3af PoE
is limited in its capacity and might not be sufficient to power your DMP and two USB peripherals
simultaneously.
Remote Control FAQs
Q.
How can I improve the effectiveness of a DMP remote control?
A.
Compensate for known factors.
