We can also mix both modes (Direct and Appliance) but for backup purpose the best solution remains the
Appliance mode.

Since the Access Points can not benefit from the Inline Power capabilities of the OmniAccess Wireless
Switch, the Ethernet switch must be capable of supplying sufficient and standard format power (full 15W
limit of IEEE 802.3af.) In the event that this can not be achieved, several options are available:
•
The OmniAccess Access Point can be supported via a localized
external power supply. This AC/DC transformer is the same
type of device used to recharge batteries in PDAs, mobile
phones, and some laptop computers. While an available
option, the use of localized power is discouraged due to the
likely location of Access Point placement and this proximity to
AC outlets, fire-code safety concerns, and power autonomy costs.
•
Inline Power Injectors can be used to provide IEEE 802.3af power to
individual Access Points. These low-cost, single port (one in, one out)
injectors can be used in situations where only one or a few devices
require power. These devices require a local AC outlet
connection to produce IEEE 802.af power and then inject
this power along with the Ethernet traffic that pass
transparently through it.
•
Much like the above discussed Inline Power Injector, Inline Power
Patch Panels can be used to achieve the same effect when more than
a few devices require IEEE 802.3af power. Alcatel-Lucent
offers Power Patch Panels in 6, 12, and 24 port varieties.
