Cisco Catalyst IW9165E - Powering the Access Point

Step 4 If necessary, strip the other end of the ground wire and connect it to a reliable earth ground such as a grounding rod or
appropriate ground point on a grounded pole. Length of the ground cable should not exceed 1 meter, and 0.5 meter is
preferred. Use supplied oxide inhibitor on the grounded interface.
Powering the Access Point
The AP supports these power sources:
• DC power – 24–48 VDC
• Power-over-Ethernet (PoE)
The AP can be powered via the PoE input from an inline power injector or a suitably powered switch port.
Depending on the configuration and regulatory domain, the required power for full operation is 802.3bt or
UPOE.
For more information, see Power Sources.

Connecting a Power Injector
The AP supports the following power injector:
Table 2: Supporting Power Injectors
DescriptionPower Source
60W rated outdoor power injector, 5GEIW-PWRINJ-60RGDMG=
The power injector provides DC voltage to the AP over the Ethernet cable and supports a total end-to-end
Ethernet cable length of 100 m (328 ft) from the switch to the AP.
When an optional power injector powers your AP, follow these steps to complete the installation:
Step 1 Before applying PoE to the AP, ensure that the AP is grounded (see Grounding the Access Point, on page 9).
Step 2 Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
