Chapter 2 Installing the Access Point
Powering the Access Point
Step 2
Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied
grounding lug.
Note
The grounding lug and hardware used must comply with local and national electrical codes.
Step 3
Open the anti-corrosion sealant (supplied), and apply a liberal amount over the metal surface where the
ground strap screw holes are located (see
Step 4
Connect the grounding lug to the access point grounding screw holes (see
) using the supplied
two Phillips head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to
22 to 24 lb-in (2.49 to 2.71 Nm).
Step 5
If necessary, strip the other end of the ground wire and connect it to a reliable earth ground, such as a
grounding rod or an appropriate grounding point on a metal streetlight pole that is grounded (see
Figure 2-3
).
Powering the Access Point
Warning
Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Warning
This equipment must be externally grounded using a customer-supplied ground wire before power is
applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available.
Statement 366
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
The 1572 access point supports these power sources:
•
DC power – 24- 57 VDC
•
Power-over-Ethernet (PoE)
The 1572 access point can be powered via the PoE input from an in-line power injector or a suitably
powered switch port. Depending on the configuration and regulatory domain, the required power for full
operation is UPoE. For the 1572E, 802.3at power is sufficient for all regulatory domains and full 2x2
MIMO operation on both 2.4 and 5 GHz radios. Either the AIR-PWRINJ4= or the AIR-PWRINJ1500-2=
power injector can be used.
For the 1572I, UPoE powered switch port or the AIR-PWRINJ1500-2= power injector is required for
full operation of the 3x3 MIMO on the 2.4 GHz radio in the regulatory domains that allow for high 2.4
GHz transmit power (Regulatory domains -A, -D, -F, -K, -N, -Q, -T, -Z). If the 1572I is powered by a
PoE+ (802.3at power) switch port or the AIR-PWRINJ4= power injector, then the access point will
automatically disable one of the 2.4 GHz transmitters and the radio will operate in 2x3 MIMO mode.
