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.
