About This Manual Organization The H3C WA2200 Series WLAN Access Points Installation Manual is organized as follows: Chapter 1 Product Overview 2 Installation Preparations 3 Installation of Indoor APs Contents Introduces the hardware configuration, appearances, and interfaces of the WA2200 series. [. . . ] The neutral line of the power cord should not be connected with the PGND of other communications equipment. The L and N lines cannot be connected In plain areas, the protection angle of the lightning rod should be less than 45 degrees. In mountainous areas or lightning areas, the protection angle should be less than 30 degrees. The lightning protection grounding (for example, the grounding of the lightning rod) should be connected to the earthing conductor of the equipment room. The antenna support is already prepared according to the design requirements. A feeder lightning rod is already installed and grounded according to the design requirements. Power lightning arrester, port lightning protector, and feeder lightning arrester are recommended for outdoor installations. The power lightning arrester and the feeder lightning arrester should be near the AP, and the network interface lightning arrester should be near the peer device of the AP. The network interface lightning arrester should be installed where the network cable is just led out of the room. Use a shielded twisted pair cables for an AP used outdoors. Ensure that the devices at the two ends of the cable are well grounded. 4 5 Lightning arrester 6 Feeder 7 Outdoor lightning arrester 8 Network cable After you have completed the preparations, you can start installing the AP. The installation of indoor models is different from that of the outdoor models. For details, refer to 3 "Installation of Indoor APs" on page 3-1 and 4 "Installation of Outdoor APs" on page 4-1. 2-4 3 Installation of Indoor APs You can directly place an indoor model (including the enhanced model) on a desk. The rubber feet on the bottom of the AP help you to place it horizontally. Or you can fix it onto a wall by using the wall-mounting bracket. The following introduces the wall-mounting procedure of the indoor models and enhanced model in detail. Installation Flowchart Figure 3-1 shows the installation flowchart of the indoor models and enhanced model. Figure 3-1 Installation flowchart of an indoor AP Start Determine the installation position Install the AP Connect the power supply and network End Determining the Installation Position Determine the installation position by observing the following principles: Leave as few obstacles (such as wall and ceiling) as possible between the AP and stations. Keep the AP far away from electronic devices (such as microwave oven) that may generate RF noise. Install the AP in a place where it will not hinder people's daily work and life. Do not install the AP in a place where water seeping, water soaking, and condensing occur. Prevent water or moisture from entering the AP. Ensure the intensity and structure of the ceiling meet the requirements for ceiling mounting of the AP. You are recommended to reinforce the ceiling using boards if it is not strong enough. [. . . ] The SFP modules provided by H3C can be used outdoor. These SFP modules use single-mode optic fibers and have a transmission distance of 15 km (9. 32 miles). You need to configure an SFP module and a waterproof cover when connecting the AP to an uplink device through a fiber cable, as shown in Figure 4-20. Figure 4-20 Connect a fiber cable Follow these steps to connect a fiber cable: Step1 Insert an SFP module into the Ethernet optical interface on the AP. Step2 Insert the LC connectors with a waterproof cover into the two optical interfaces on the SFP module. [. . . ]
