Site-Specific Conditions
Site-Specific Conditions
Assess each location where you might want to use this equipment.
Adequate Shelter
Install and use this equipment indoors — or outdoors in a covered area.
• Never install or use it in a wet environment.
• Never install or use it near radiators or other heat sources.
Supported Voltage
There are — at most — only two supported methods to power this equipment.
• Use the standard electrical power cord that came with the equipment. Cord length determines
the maximum possible distance from the equipment to any AC electrical outlet that it can use. The
outlet itself must use standard voltage for your locale, within the range from 100V to 240V. We
r
ecommend that you use a surge suppressor, line conditioner, or uninterruptable power supply
(UPS). Please position all cables and power cords carefully. Route all cables, the power cord, and
the plug so that they cannot be stepped on or tripped over. Never allow anything to rest on
eq
uipment cables or cords.
OR
• Use 802.3af power over Ethernet (PoE), assuming that your equipment model supports
this feature. We describe PoE setup elsewhere in this guide. To learn if your equipment model
su
pports this feature, see its datasheet at http://cisco.com/go/dms/dmp/datasheets.
DHCP Access
Each new DMP (and each DMP on which you restore factory-default settings) uses DHCP to obtain its
first IP address. Therefore, a DHCP server must be reachable from the site where you set up a DMP.
Later, after your DMP is fully configured, it can use either static or dynamic IP addressing.
Signal Integrity
When physical cables are too long, the signals that they carry can degrade. Signal loss can also affect
wireless connections —
including the infrared connection between a DMP and its remote control. When
signal integrity suffers, equipment performance suffers.
