Note The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.
This document describes the Cisco Aironet AIR-ANT2535SDW-R and AIR-ANT2535SDW-RS antennas and provides electrical specifications and mounting instructions. The antenna operates over the 2.4 GHz and 5 GHz Wi-Fi bands and is designed for indoor use with the Cisco Aironet 1600, 2600, 2800, 3600, 3700, 3800, and Cisco Catalyst 9120AXE series access points. The antenna utilizes an omnidirectional radiation pattern to achieve a broad coverage area.
The AIR-ANT2535SDW-RS antenna includes circuitry to enable self-identification of the antenna by the Cisco access points. The antenna has a built-in EEPROM that can be read by the AP to automatically configure the antenna type and gain in the wireless controller.
Note The antenna’s self–identifying feature (SIA) functions with Cisco Catalyst 9120AXE AP only.
The AIR-ANT2535SDW-RS antenna has an purple marking indicating that it is a self identifying antenna (SIA), where as an orange marking on the antenna denotes that it is a non-SIA, AIR-ANT2535SDW-R antenna.
This antenna is designed for use with Cisco access points having dual-band antenna ports. These include the Cisco Aironet 1600, 2600, 3600, 3700, and Cisco Catalyst 9120AXE series access points. The antenna is intended solely for indoor deployments.
The Self Identifying Antenna model AIR-ANT2535SDW-RS= is supported only on Cisco Catalyst 9800 Series Wireless Controllers running an IOS-XE 17.4.1 release or a later release. This antenna model is not supported on Cisco AireOS Wireless Controllers.
For your safety, read and follow these safety precautions:
1. Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the size and type of antenna that you are about to install.
2. Find someone to help you—installing an antenna is often a two-person job.
3. Select your installation site with safety, as well as performance, in mind. Remember that electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
4. Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.
5. Plan your installation carefully and completely before you begin. Each person involved in an installation should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
6. When installing your antenna, follow these guidelines:
b. Do not work on a wet or windy day.
c. Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
7. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer.
8. If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company to have it removed safely.
9. If an accident should occur with the power lines, call for qualified emergency help immediately.
The antenna is designed to connect to a dedicated antenna connector on the access point. No special tools are required to install the antenna.
The antenna radiates an omnidirectional pattern in the plane of the access point. To achieve this pattern, the access point should be mounted clear of any obstructions to the sides of the radiating element. If the mounting location is on the side of a building or tower, the antenna pattern is degraded on the building or tower side.
No tools are required to mount the antenna to the access point. For information about tools required to mount the access point, see the appropriate access point documentation.
To connect the antenna to the access point, follow these steps:
Step 1 Align the antenna’s RP-TNC connector with the appropriate antenna port.
Step 2 Gently push the antenna into the port.
Step 3 Hand tighten the antenna to the port using the metal knurled ring only.
Warning Do not use the plastic body to tighten. This may damage the antenna.
