Redundant Power Supply
The AT-TQ1402 Series Access Point offers a redundant power supply
system. In addition to the power supply through the DC-IN jack, the access
point has one PoE-capable LAN port (LAN). The external power supply
connected to the DC-IN jack is the primary power source for the unit. If the
power supply unit on the access point fails, power is supplied to the
access point via the PoE port. Table 1 shows power source for the
AT-TQ1402 Series Access Point under specific conditions.
