Aruba IAP-175 Outdoor Instant Access Point
Installation Guide
The Aruba IAP-175 is a resilient, environmentally hardened, outdoor rated, dual-radio, dual-band IEEE
802.11 a/b/g/n wireless access point. This outdoor access point is part of Aruba’s comprehensive wireless
network solution. The IAP-175 can operate as an Aruba virtual controller or as a member of an Aruba
Instant wireless network.
The IAP-175 requires Aruba 3.0 Instant or later.
There are three versions of the IAP-175, which mainly differ in the way they receive power.

IAP-175P: PoE+ powered (802.3at)

IAP-175AC: AC powered (100 - 240 VAC)
The IAP-175AC can function as a Power Sourcing Equipment (PSE) device by providing power through its Ethernet
port in compliance with the IEEE 802.3af standard.

Grounding Point
Antenna Interface
The IAP-175 requires the use of detachable outdoor-rated antennas. Select the correct antenna type to
support the required frequency band (2.4 or 5 GHz) and the desired coverage pattern.
The IAP-175 is equipped with four, female N-type antenna interfaces; two on the top of the AP and two on
the bottom. The interfaces are grouped into diversity pairs, one pair is marked R0 (Radio 0) and the other
pair marked as R1 (Radio 1). R0 supports the 5 GHz frequency band and R1 supports the 2.4 GHz radio
band.

USB Console Interface
A USB serial console port is provided for connection to a terminal, allowing direct local management. Use
the included USB console cable to connect to the AP. You can download the necessary driver for USBUART adapter from support.arubanetworks.com under the Tools & Resources tab.
Use the following setting to access the terminal:

Power Interface
The type of power interface on your IAP-175 depends on which model you have purchased.

IAP-175P: This version does not include a power interface since it is only powered by PoE+ (802.3at).

IAP-175AC: 1x AC power connector
For the IAP-175AC, only use the AC power cord with model number CBL-AC-INTL.
Ethernet Interface
The IAP-175 is equipped with a 10/100/1000Base-T Gigabit Ethernet port for wired network connectivity. On
the IAP-175P, this port also supports IEEE 802.3at Power over Ethernet (PoE), accepting 48 VDC as a
standards-defined powered device (PD) from a power sourcing equipment (PSE) device, such as a PoE
midspan injector. Inversely, the IAP-175AC can act as a PSE device to provide IEEE802.3af PoE power to
devices connected to the Ethernet port.
Grounding Point
Always remember to protect your IAP-175 by installing grounding lines. The ground connection must be
complete before connecting power to the IAP-175 enclosure. Ensure that the resistance is less than 5 ohm
between the ground termination point and the grounding tier.
IAP-175P LED Status Indicators
The IAP-175 include visual indicators for power, link, and radio status. Additionally, each radio has a fourLED array that indicates received signal strength (RSSI).
The RSSI LED indicators represent varying degrees in the RSSI level. The absence of a signal is indicated by no
LED response, and full signal strength is indicated when all four LEDs are active and lit.

IAP-175AC LED Status Indicators
The IAP-175 include visual indicators for power, link, heat and radio status. Additionally, each radio has a
four-LED array that indicates received signal strength (RSSI).
The RSSI LED indicators represent varying degrees in the RSSI level. The absence of a signal is indicated by no
LED response, and full signal strength is indicated when all four LEDs are active and lit.
