Cisco IW-PWRADPT-MFITHZ= Power Supply Unit Installation Guide
This document describes the Cisco IW-PWRADPT-MFITHZ= Power Supply Assembly (referred to as the power supply or PSU in this document) and provides instructions for its assembly and mounting.
Overview
The Cisco power supply model IW-PWRADPT-MFITHZ= is an outdoor, single-phase AC/DC PSU with a 60-Watt output. It delivers a DC voltage output of 48V and operates within the input range of 100–240 VAC. The protective case encloses the AC/DC power unit to ensure safe operation in hazardous locations. The PSU must be used with ½" NPT cable glands that comply with IECEx certification standards.
Mount the PSU individually on each supporting Cisco AP.

Regulatory Information
The following information is for FCC compliance of Class B devices:
The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
-
Turn the television or radio antenna until the interference stops.
-
Move the equipment to one side or the other of the television or radio.
-
Move the equipment farther away from the television or radio.
-
Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
