Chapter 1 AP300 Series Introduction The Meru AP300 Access Point delivers high performance, full-speed, draft 2.0 compatible 802.11n connectivity while simultaneously supporting legacy 802.11a/b/g devices. The Meru Networks family of AP300 Access Points is supported by System Director Release 3.4.SR3 and later. A 2 L A N R F 1 R F 2 A 2 00207 A 2 Figure 1: AP300 Key product features include: z 802.11n support with channel bonding in both 2.4GHz and 5GHz frequency bands.
Each of these Access points may be powered by a standard 802.3af for 2x2 MIMO Mode. For 3x3 full channel mode, use either a power supply or a a 802.3at PoE device.
Safety Precautions Chapter 2 Installing the AP300 This chapter describes how to physically install the Meru AP300. It contains the following sections: z Safety Precautions z Unpack the AP300 z Determine Power Requirements z Installation Requirements z Install the Access Points z Configure AP300 Software z Check AP300 LED Activity z Configure AP300 Software z Troubleshooting Safety Precautions IMPORTANT—Read and follow the regulatory instructions in Appendix C before installing and operating this product.
Determine Power Requirements Determine Power Requirements Your power requirements will vary, depending on which AP300 radios are deployed and what mode is used. See Table 2. Table 2: AP300 Power Options AP300 Configuration Power Options 1 radio – b/g mode Either a power supply (included) or PoE 802.3af 1 radio – n-mode Either a power supply (included) or PoE 802.3af 2 radios – 1 b/g-mode, 1 n mode For 2x2 MIMO mode, use either a power supply (included) or PoE 802.3af.

There are holes for passing the PoE Ethernet or external power supply cable through the bracket if the bracket is mounted on a junction box. To complete this installation, you need the items listed in Table 3.

Install the Access Points z Access to wall outlet or a to a Power over Ethernet (PoE) connection to the network switch servicing the controller. Most installations receive the best coverage using the following guidelines: z Install APs toward the center of the building. z Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels. z Relative to the ground, orient the antenna up or down, not sideways. The previous guidelines are general guidelines.
Install the Access Points A 2 L A N R F 1 R F 2 A 2 00207 A 2 Figure 6: Horizontal AP300 Mount AP300 on a Wall If you are replacing AP150s, you can use the existing brackets: the AP150 and AP300 use the same bracket. If you are replacing AP200s, the AP300 bracket can be attached to the old bracket with shoulder screws (see Appendix A); you don’t have to remove the old brackets. Note: The AP300 ships with the mounting bracket attached. To mount an AP300 on a wall: 1.

Either connect an external power supply to the power connector and plug it into the wall, or connect an appropriate PoE power device to the Ethernet port (see Figure 7). Check AP300 LED Activity After the AP300 is connected, the LEDs should light (see Figure 8).

Configure AP300 Software — 802.3-af: Default power supply. Select this when using a traditional PoE. This power supply type only supports 2x2 MIMO mode. — 802.3-at: Select when using a higher-powered, next generation PoE. This power supply type supports 3x3 MIMO mode. — 5V-DC: Select when AP300 is plugged into a wall outlet. This power supply type supports 3x3 MIMO mode. — dual-802.3: Select when using a dongle that combines power from two traditional PoEs. This power supply type supports 3x3 MIMO mode.
Troubleshooting 9. Configure Channel Width by clicking the drop-down list and selecting either 40 MHz Extension channel above or 40 MHz Extension channel below. The ‘channel above’ and ‘channel below’ are relative to the value set in the Channel control setting (see Figure 11, the third setting from the top). This configures the channel bonding. 10.

Appendix A AP300 Brackets The AP300 is designed to be used with brackets supplied by other vendors. Meru APs are compatible with the Cisco 1230 series brackets, but the 1240 and 1250 series brackets are new and not compatible. If you reuse a Cisco 1230 series bracket, follow these steps: 1. Obtain three of the screws shown in Figure 12.
