Installation Notes

Caution

Cisco Aironet power injectors are designed for use with Cisco Aironet access points and bridges only.
Do not use the power injector with any other Ethernet-ready device. Using the power injector with other
Ethernet-ready devices can damage the equipment.

Use Only One Power Option

You cannot provide redundant power to 1100 and 1200 series access points with both DC power to its
power port and inline power from a patch panel or powered switch to the access point’s Ethernet port. If
you apply power to the access point from both sources, the switch or power patch panel might shut down
the port to which the access point is connected.

Figure 2

shows the power configuration that can shut

down the port on the patch panel or powered switch.

Improper Power Configuration Using Two Power Sources

Using the AC Power Adapter

If you use the AC power adapter to provide power to the access point, you do not need to adjust the access
point configuration.

Using a Switch Capable of IEEE 802.3af Power Negotiation

If you use a switch to provide Power over Ethernet (PoE) to the access point and the switch supports the
IEEE 802.3af power negotiation standard, select Power Negotiation on the System Software: System
Configuration page.

Using a Switch That Does Not Support IEEE 802.3af Power Negotiation

If you use a switch to provide Power over Ethernet (PoE) to the access point and the switch does not
support the IEEE 802.3af power negotiation standard, select Pre-Standard Compatibility on the
System Software: System Configuration page.
