With the 802.11a, or with both the 802.11a and 802.11b radios installed, the
Cisco Aironet 1100 and 1200 Series
,
can be
powered over Ethernet with the optional inline power injector
, by a switch
with inline power
,
, by an inline
power patch panel
, or by a
universal power supply
. The 1100 can
also be powered by any of the same four options.
Keep in mind that the
powered switches, such as the powered blades for the Catalyst 4000, Cat6K, and
3550-pwr switches, can power Cisco IP Phones.

WARNING:
Never connect both the DC power to the AP power port and inline
power simultaneously
.

2.4 GHz and 5 GHz AP technologies use 48 volts. This allows the
power to be sent over the unused pairs of the Category 5 cable without
disrupting the data signal. Less hardware is required for the installation
.
Inline power further reduces the installation costs, as an
electrician is not required. Anyone qualified to run Category 5 cable can
install the cabling required to power a Cisco Aironet Access Point. Standard
Category 5 cable requirements still apply (maximum 328 feet or 100 meters).
2.4 GHz technology is compatible with the entire line of Cisco power
enabled devices. The 5 GHz technology is also compatible if utilizing only one
radio. Many of these devices already exist to power items such as the Cisco
VoIP phones.
A Power Injection module is shipped with every 350 Series
Access Point. The 350 Series Access Point can only receive power through the
RJ-45 port. There are no other means of powering the access point. With the
1100 and 1200 Series AP, an AC power brick is shipped with the access point
. If inline power
is needed, then a separate inline power injector is available
.
There are
five steps necessary to follow when connecting the access point:
- Plug the RJ-45 Ethernet cable into the Ethernet port on the back of the
access point.
- Connect the other end of the Ethernet cable to the 10/100 Ethernet LAN.
- Plug the power adapter into a suitable power receptacle.
- Plug the power connector into the back of the access point. At start-up,
all three LEDs on the access point slowly blink amber, red, and green in
sequence. The sequence takes a few minutes to complete. During normal
operation, the LEDs blink green.
- Follow the configuration steps to assign basic settings to the access
point. The access point does not have an on/off switch. Power is applied to the
unit when it is plugged in. Do not connect the Ethernet cable when the access
point is powered up. Always connect the Ethernet cable before applying power to
the access point.
