Chapter 2 Installing the Access Point
Powering the Access Point
Caution Do not place the power injector in an unprotected outdoor environment because water could get into the
power injector and cause a short circuit and possible fire.
Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV)
requirements in IEC 60950 based safety standards Statement 1033
Connecting a 1570 Series Power Injector
The 1570 Series Access Points support the following power injectors:
• AIR-PWRINJ1500-2= — 100-240 VAC input, indoor use only
• AIR-PWRINJ4= — 100-240 VAC input, indoor use only
The power injector provides (AIR-PWRINJ1500-2=) 56 VDC to the access point over the Ethernet cable
and supports a total end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the access
point.
When your access point is powered by an optional power injector, follow these steps to complete the
installation:
Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the “Grounding
the Access Point” section on page 2-27).
Step 2 Review Figure 2-2 to identify the components needed for the installation.
Note The 1500 power injector can only be used in an indoor environment, therefore, the cable from
the injector must travel from the protected location to the outside mounted access point.
Step 3 Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
