•
Do not mount a DAP to a metal surface.
•
Do not roll up the extra cabling behind a DAP.
•
Position DAPs upright on walls. DAPs must be at least 30 cm from the
ceiling.
•
Position DAPs at least 1 meter (m) from large concrete or stone
columns and from major building structural members such as support
beams or columns.
•
Position the DAPs high enough to clear obstructions between the
DAPs and the cell edge close to the ceiling.
•
Mount the DAPs clear of obstacles such as pipes or ducts.
To install the DAPs outdoors, see
275).
DAP power configuration
DAPs are powered using one of the following methods:
•
Locally using an RJ-11 connector. The AC voltage must be 40V (+ or
--10 percent). Use an AC adaptor that provides at least 10 Watts. For
part numbers of available AC adaptors, see
(page 27).

•
Through Power over Ethernet (PoE) as defined by IEEE802.3af
specifications. The DAPs support both phantom power and power over
spare wires. The following specifications apply to PoE power.
—
Minimum 36 Volts and maximum 60 Volts of voltage at the DAP
—
Standard RJ-45 connector, using the spare wires pins (wires)
—
Maximum cable length of 100 meters
Both phantom power and power over spare wires are provisioned on the
same DAP to provide system redundancy. The power input providing the
highest voltage is active. If one power input fails, the other takes over
without service interruption.
