A campus infrastructure supports wireless clients via Cisco Aironet AG Series 1230, 1240,
and 1250 access points. With DNS and DHCP configured, the 1230 and 1240 access points
appear to boot and operate normally. However, the 1250 access points do not seem to
operate correctly. What is the most likely cause of this problem?
A.
DHCP with option 150
B.
DHCP with option 43
C.
PoE
D.
DNS
E.
switch port does not support gigabit speeds
Explanation:
Cisco Aironet 1250 Series Access Point can be powered locally by the 1250 DC power
module or an IEEE 802.3af compliant Power-over-Ethernet (PoE) power source. However, if
the access point is powered by an 802.3af source, only one radio is supported because the
two radio operation requires 18.5 watts. Two radio operation is supported only by the 1250
series power injector and an 802.at compliant PoE switch.
