Power Options

With a Gigabit Ethernet (10/100/1000) interface, the Cisco Aironet 1250 Series offers the flexibility of inline as well
as local power options. The Cisco Aironet 1250 Series Access Point can be powered by a Cisco Ethernet switch, a
power injector, or a local power supply. The number of radio modules determines which Cisco Ethernet switch can
power the Aironet 1250 Series Access Point.

Powering the Aironet 1250 Series Access Point with 802.3af Power over Ethernet

The Aironet 1250 Series Access Point with one RM1252 radio module installed requires 12.95W, which is within
the 802.3af Power over Ethernet (PoE) standard. Any Cisco switch supporting 802.3af may be used to power the
Aironet 1250 Series Access Point with one RM1252 radio module installed. This is ideal for businesses that chose
to only deploy on a single frequency (2.4 GHz or 5 GHz). A single radio provides optimum performance with
approximately 300 Mbps maximum PHY data rate. Customers who deploy dual-band, 802.11n radios and power
the 1250 Series using standard 802.3af will have more reliable and predictable coverage than that provided by
traditional 802.11a/g networks; however, operation will be limited to a single transmitter per radio with maximum
PHY data rates of 150 Mbps instead of 300 Mbps per radio. Customers with a significant investment in 802.11
a/b/g client devices that have low-to-medium bandwidth needs but high-reliability requirements will benefit the most
from this type of deployment scenario.

Powering the Aironet 1250 Series Access Point with Cisco Enhanced PoE

Cisco Enhanced PoE was designed for customers who want to install new PoE-enabled technologies that require
greater than 15.4W per port to function at full capability, such as wireless technology based on the IEEE 802.11n
standard. Cisco Enhanced PoE provides the full power requirements for dual-radio modules and eliminates the
need to run an additional cabling drop or insert a separate power injector. Support for Enhanced PoE is currently
available on a variety of Cisco Catalyst® switching platforms. For more information on Enhanced PoE, visit
