16 Installation Precautions To keep the IEEE 802.11n Wireless Access Point well while you are installing it, please read and follow these installation precautions. 1. Users MUST use a proper and well-installed grounding and surge arrestor with the IEEE 802.11n Wireless Access Point; otherwise, a random lightening could easily cause fatal damage to IEEE 802.11n Wireless Access Point. EMD (Lightning) DAMAGE IS NOT COVERED UNDER WARRNTY. 2. Users MUST use the “Power cord & PoE Injector” shipped in the box with the IEEE 802.11n Wireless Access Point. Use of other options will likely cause damage to the IEEE 802.11n Wireless Access Point. 3. Users MUST power off the ZAC Access Point first before connecting the external antenna to it. Do not switch from built-in antenna to the external antenna from WEB management without physically attaching the external antenna onto the unit; otherwise, damage might be caused to the ZAC Access Point itself. Product Package The product package you have received should contain the following items. If any of them are not included or damaged, please contact your local vendor for support. IEEE 802.11n Wireless Access Point × 1  Detachable 5dBi Antennas × 2  Pole Mounting Ring × 2  24VDC Power Cord & PoE Injector × 1  Ferrite Suppression Core × 1  Grounding Wire × 1  Product CD × 1 Product CD contains Quick Installation Guide and User Manual. Note: 4. This device is for indoor use only.
17 Pole Mounting Ring Ferrite Suppression Core 24VDC Power Cord & PoE Injector Users MUST use the “Power cord & PoE Injector” shipped in the box with the IEEE 802.11n Wireless Access Point. Use of other options will likely cause damage to the IEEE 802.11n Wireless Access Point. Warning:
18 Hardware Installation Connect up 1. The bottom of the Access Point is a movable cover. Grab the cover and pull it back harder to take it out as the figure shown below. 2. Plug a standard Ethernet cable into the RJ45 port. 3. Slide the cover back and press down the lock button to seal the bottom of the Access Point.
19 Using the Grounding Wire The IEEE802.11n Wireless Access Point is equipped with a grounding wire. It is important that the Access Point, cables, and PoE Injector must be properly connected to earth ground during normal use against surges or ESD. 1. Remove the screw on the grounding point at the bottom of the Access Point.2. Put the grounding wire on the grounding point at the bottom of the Access Point. Then screw thegrounding wire to tighten up.Install External Antennas The Access Point provides two reverse SMA antenna connectors for connecting external antennas. 1. Connect external antennas that came with the package to the SMA-type connectors on top of the Access Point.
20 Users MUST power off the Access Point first before connecting the external antenna to it. Do not power on the device for a certain of time without physically attaching the external antenna; otherwise, damage might be caused to the unit itself. 2. Bend the antennas to 90 degree or 45 degree. 3. You may turn one antenna 45 degrees to the left and the other 45 degrees to the right. The tilted antennas are a reasonable way to operate and the best way if the antennas are fairly close together since they couple together much less than if they are both pointed in the same direction (parallel). Warning:
21 The polarization of antennas should be properly aligned. Maximum signal strength between bridges occurs when both bridges are using identical polarization. 4. Tighten up the connector joint clockwise to fix the antennas. 5. To adjust antennas, loose the connector joint counterclockwise first, then adjust antenna to the desired position. DO NOT bend or turn the antennas without loosening the connector joint, otherwise, damage might be caused to the antennas. Note:
22 6. Antenna installation is complete. Mount the AP on a Pole 1. Turn the Access Point over. Put the pole mounting ring through the middle hole of it. Note that you should unlock the pole mounting ring with a screw driver before putting it through the device as the following right picture shows.
23 2. Mount the Access Point steadily to the pole by locking the pole mounting ring tightly. Power Up 1. Connect power cord to the PoE injector as the following right picture shows. P.S. This device is for indoor use only.
24 2. Connect the Ethernet cable that connects the Access Point to the “POE” port of the PoE injector as figured below. 3. Connect the power plug to a power socket. The Access Point will be powered up immediately. Connect to the Access Point To be able to configure and manage the Access Point, please do the followings: 1. Open the ferrite core by unsnapping the connector latches. The core will open, revealing a concave surface. 2. Lay the Ethernet cable into the core, usually within 2 to 3 inches of the connector. You may have to experiment with the final location depending on the effectiveness of the high frequency abatement.
25 3. Loop the cable around and through the core. This helps "lock" the core in place, and may be required in circumstances with severe interference. 4. Close the core and snap the halves back together. The ferrite is professionally installed and a shrink wrap has been put around the ferrite so the users CAN’T take the ferrite off. Note:
26 5. Connect the Ethernet cable with suppression core to the “Data In” port of the PoE injector. 6. Connect the other end of Ethernet cable to a PC or a switch hub. The hardware installation is complete. To configure the Access Point, please refer to Chapter 3 Basic Settings.

As you can see, this management interface provides five main options in the black bar above, which are Status, System, Wireless, Management and Tools. Figure 4 Main Page The username and password are case-sensitive, and the password should be no more than 19 characters! Note:
30 Basic System Settings For users who use the IEEE 802.11n Wireless Access Point for the first time, it is recommended that you begin configuration from “Basic Settings” in “System” shown below: Figure 5 Basic System Settings Device Name: Specify the device name, which is composed of no more than 15 characters with (0-9), (A-Z), (a-z) or (-). Country Region: For FCC domain, default country is United States only. Network Settings The Network Settings allows you to change network, IP address and configure few network parameters like spanning tree and management VLAN ID. Make configuration in “Network Settings” from “System”.
31 Figure 6 Network Settings Network Mode: Specify the network mode, including Bridge and Router. It is easy to configure parameters in Bridge Mode; however, users must pay extra attention to the way they configure the device when it is set to Router Mode. For details, please refer to TCP/IP Settings”. Spanning Tree: Spanning Tree Protocol (STP) is a link management protocol for AP which provides path redundancy while preventing loops in a network. STP allows only one active path at a time between the Access Points but establish the redundant link as a backup if the initial link fails. STP Forward Delay: STP Forward Delay is the time spent in detecting and learning network tree topology state before entering the forward state. Default time value is 1 sec. 802.1Q VLAN: To allow users on the VLAN to access the WEB page of the IEEE 802.11n Wireless Access Point, you need to enable “Enable 802.1Q VLAN” and assign a management VLAN ID for your device. Make sure the assigned management VLAN ID is identical to your network VLAN ID to avoid failures of accessing the Web page of the IEEE 802.11n Wireless Access Point. IP Address Assignment
32 Users may change the settings for IP Address, Subnet Mask, and DHCP Server. Obtain IP Address Automatically: If a DHCP server exists in your network, you can check this option, thus the IEEE 802.11n Wireless Access Point is able to obtain IP settings automatically from that DHCP server. When the IP address of the Access Point is changed, the clients on the network often need to wait for a while or even reboot before they can access the new IP address. For an immediate access to the bridge, please flush the netbios cache on the client computer by running the “nbtstat –r” command before using the device name of the Access Point to access its Web Management page. In case the IEEE 802.11n Wireless Access Point is unable to obtain an IP address from a valid DHCP server, it will fall back to default static IP address. Use Fixed IP Address: Check this option. You have to specify a static IP address, subnet mask, default gateway and DNS server for the Access Point manually. Make sure the specified IP address is unique on your network in order to prevent IP conflict. If the IEEE 802.11n Wireless Access Point configured as Router mode, you need to configure some additional TCP/IP parameters for accessing the Internet. Figure 7 TCP/IP Settings (Router) Note:
33 WAN Access Type: Specify the Internet access method to Static IP, DHCP or PPPOE. Users must enter WAN IP Address, Subnet Mask, Gateway settings provided by your ISPs. LAN Settings: When DHCP Server is disabled, users can specify IP address and subnet mask for the Access Point manually. Make sure the specified IP address is unique on your network in order to prevent IP conflict. When DHCP Server is enabled, users may specify DHCP IP Address Range, DHCP Subnet Mask, DHCP Gateway and Lease Time (15-44640 minutes). A DHCP relay agents is used to forward DHCP requests and replies between clients and servers when they are not on the same physical subnet. To enable the DHCP relay agent, check the “Enable DHCP Relay” checkbox and enter the IP address of the DHCP server. In AP mode, the IEEE 802.11n Wireless Access Point must establish connection with another wireless device before it is set to Router mode. To access the unit in Router mode via wired port, please type the WAN IP address to enter the web page for WAN is on wired port and LAN is on wireless port. Or, you can access device through the wireless device connected with the Access Point. In wireless client mode, users can access the Access Point via its wired port, for WAN is on wireless port and LAN is on wired port when device is set to Router mode. Bridge mode and AP Repeater mode are similar to AP mode when device is set to Router mode; WAN is on wired port and LAN is on wireless port. Thus users must also connect the Access Point with another wireless device before it is set to Router mode and access the Access Point via the connected wireless device. Time Settings Compliant with NTP, the IEEE 802.11n Wireless Access Point is capable of keeping its time in complete accord with the Internet time. Make configuration in “Time Settings” from “System”. To use this feature, check “Enable NTP Client Update” in advance. Warning:

NTP Server: Select the time server from the “NTP Server” dropdown list. Manual IP: Manually input the IP address of available time server. Hit “Apply” to save settings. RADIUS Settings RADIUS (Remote Authentication Dial-In User Service) is a server for remote user authentication and accounting; playing a central role in the network in providing the capabilities of authenticating, authorizing, accounting, auditing, alarming and etc. It allows an organization to maintain user profiles in a central database that all remote servers can share. Open “RADIUS Settings” in “System” to make RADIUS configuration.
35 Figure 9 RADIUS Settings Authentication RADIUS Server This is for RADIUS authentication. It can communicate with RADIUS through IP Address, Port and Shared Secret. IP Address: Enter the IP address of the Radius Server; Port: Enter the port number of the Radius Server; Shared Secret: This secret, which is composed of no more than 31 characters, is shared by the IEEE 802.11n Wireless Access Point and RADIUS during authentication. Global-Key Update: Check this option and specify the time interval between two global-key updates. Firewall Filtering The firewall is a system or group of systems that enforce an access control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an un-trusted network. IEEE 802.11n Wireless Access Point has capabilities of Source IP Filtering, Destination IP Filtering, Source Port Filtering, Destination Port Filtering, Port Forwarding as well as DMZ. This is available only under Router Mode. To make the Firewall Filtering page show up, select Router from System > Network Settings and it will appear under System menu. Tick Enable Firewall Filtering to enable firewall functions.
36 Figure 10 Source IP Filtering Filter Type: MAC Filtering: The MAC filtering gives users the ability to restrict packets from certain devices by entering MAC address. Source IP Filtering: The source IP filtering gives users the ability to restrict certain types of data packets from your local network to Internet through IEEE 802.11n Wireless Access Point. Use of such filters can be helpful in securing or restricting your local network. Destination IP Filtering: The destination IP filtering gives you the ability to restrict the computers in LAN from accessing certain websites in WAN according to specified IP addresses. Source Port Filtering: The source port filtering enable you to restrict certain ports of data packets from your local network to Internet through IEEE 802.11n Wireless Access Point. Use of such filters can be helpful in securing or restricting your local network. Destination Port Filtering: The destination port filtering enables you to restrict certain ports of data packets from your local network to Internet through IEEE 802.11n Wireless Access Point. Use of such filters can be helpful in securing or restricting your local network. Port Forwarding The port forwarding allows you to automatically redirect common network services to a specific machine behind the NAT firewall. These settings ne are only necessary if you wish to host some sort of
37 server like a web server or mail server on the private local network behind IEEE 802.11n Wireless Access Point’s NAT firewall. Figure 11 Port Forwarding DMZ A Demilitarized Zone is used to provide Internet services without sacrificing unauthorized access to its local private network. Typically, the DMZ host contains devices accessible to the Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. To enable it tick the Enable DMZ checkbox. Figure 12 DMZ Enable DMZ: DMZ Host IP Address: Type the IP address of the device you want to place under DMZ.
38 Basic Wireless Settings Open “Basic Settings” in “Wireless” as below to make basic wireless configuration. Figure 13 Basic Wireless Settings Disable Wireless LAN Interface: Check this option to disable WLAN interface, then the wireless module of IEEE 802.11n Wireless Access Point will stop working and no wireless device can connect to it. Operation Mode: Four operating modes are available in IEEE 802.11n Wireless Access Point. AP: The IEEE 802.11n Wireless Access Point establishes a wireless coverage and receives connectivity from other wireless devices. Wireless Client: The IEEE 802.11n Wireless Access Point is able to connect to the AP and thus join the wireless network around it. Bridge: The IEEE 802.11n Wireless Access Point establishes wireless connectivity with other APs by keying in remote MAC address. Please refer to the “WDS Setting” for detailed configuration. AP Repeater: The IEEE 802.11n Wireless Access Point servers as AP and Bridge concurrently.
39 In other words, the IEEE 802.11n Wireless Access Point can provide connectivity services for ACCESS POINTs under Bridge mode. Wireless Network Name (SSID): This wireless network name is shared among all associated devices in your wireless network. Keep it identical on all those devices. Note that the SSID is case-sensitive and cannot exceed 32 characters. Broadcast SSID: Under AP mode, hiding network name is necessary when you are in a wireless environment that may have potential risk. By disabling broadcast SSID, the STA can not scan and find IEEE 802.11n Wireless Access Point, so that malicious attack by some illegal STA could be avoided. 802.11 Mode: The IEEE 802.11n Wireless Access Point can communicate with wireless devices of 802.11b/g or 802.11b/g/n. (For ZAC-1023-5-13 it’s 802.11a or 802.11n) Channel Mode: Four levels are available: 5MHz, 10MHz, 20MHz and 40MHz. The last one can enhance data throughput, but it takes more bandwidth, thus it might cause potential interference Channel: Channel varies much as the available band differs from country to country. Select a proper operating channel in the drop-down list according to your situation. Extension Channel: Only applicable to AP, AP Repeater, and 40MHz channel width) indicates the use of channel bonding that allows the IEEE 802.11n Wireless Access Point to use two channels at once. Two options are available: Upper Channel and Lower Channel. Data Rate: Usually “Auto” is preferred. Under this rate, the IEEE 802.11n Wireless Access Point will automatically select the highest available rate to transmit. In some cases, however, like where there is no great demand for speed, you can have a relatively-low transmit rate for compromise of a long distance. HT Protect: Enable HT (High Throughput) protect to ensure HT transmission with MAC mechanism. Under
40 802.11n mode, wireless client can be divided into HT STA and Non-HT STA, among which the one with HT protect enabled gets higher throughput. Antenna Gain The antenna gain calculates the TX power back off needed to remain in compliance with regulations. You should use the default detachable antenna and adjust the antenna gain settings for the output power. Output Power (per chain): Specify the signal transmission power. The higher the output power is, the wider the signal can cover, but the power consumption will be greater accordingly. Enable MAC Clone Available only under wireless client mode, it hides the MAC address of the AP while displays the one of the device connected to the Access Point. Default is Auto MAC Clone. User may choose to enter the MAC address to be cloned manually. Site Survey Under wireless client mode, the IEEE 802.11n Wireless Access Point is able to perform site survey, through which, information on the available Access Points will be detected. Open “Basic Settings” in “Wireless”, by clicking the “Site Survey” button beside “Wireless Mode” option, the wireless site survey window will pop up with a list of available AP in the vicinity. Select the AP you would like to connect and click “Selected” to establish connection.

42 Figure 16 VAP Profile Settings Profile Name: Name of the VAP profile SSID: Assign a network name for the VAP Broadcast SSID: In AP mode, hiding network name is necessary when you are in a wireless environment that may have potential risk. By disabling broadcast SSID, the STA cannot scan and find the IEEE 802.11n Wireless Access Point, so that malicious attack by some illegal STA could be avoided. Wireless Separation: Wireless separation is an ideal way to enhance the security of network transmission. Under the mode except wireless client mode, enable “Wireless Separation” can prevent the communication among associated wireless clients. WMM Support: WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a priority limit on the basis of data type under AP mode only, thus those time-sensitive data, like video/audio data, may own a higher priority than common one. To enable WMM, the wireless client should also support it Max. Station Number: By checking the “Max. Station Num” the Access Point will only allow up to 32 wireless clients to
43 associate with for better bandwidth for each client. By disabling the checkbox the Access Point will allow up to 128 clients to connect, but it is likely to cause network congestion or poor performance. IGMP Snooping: Available in AP/Router mode, IGMP snooping is the process of listening to IGMP network traffic. By enabling IGMP snooping, the AP will listen to IGMP membership reports, queries and leave messages to identify the ports that are members of multicast groups. Multicast traffic will only be forwarded to ports identified as members of the specific multicast group or groups. Security Setting: To prevent unauthorized radios from accessing data transmitting over the connectivity, the IEEE802.11n Wireless Access Point provides you with rock solid security settings. For detailed information please go to Chapter 4 Wireless Security Setting.

Short GI Under 802.11n mode, enable it to obtain better data rate if there is no negative compatibility issue. RTS Threshold The IEEE 802.11n Wireless Access Point sends RTS (Request to Send) frames to certain receiving station and negotiates the sending of a data frame. After receiving an RTS, that STA responds with a CTS (Clear to Send) frame to acknowledge the right to start transmission. The setting range is 0 to 2346 in byte. Setting it too low may result in poor network performance.
45 Leave it at its default of 2346 is recommended. Fragmentation Length Specify the maximum size in byte for a packet before data is fragmented into multiple packets. Setting it too low may result in poor network performance. Leave it at its default of 2346 is recommended. Beacon Interval Specify the frequency interval to broadcast packets. Enter a value between 20 and 1024. DTIM Interval DTIM, which stands for Delivery Traffic Indication Message, is contained in the data packets. It is for enhancing the wireless transmission efficiency. The default is set to 1. Enter a value between 1 and 255. Preamble Type It defines some details on the 802.11 physical layer. “Long” and “Auto” are available. Distance: To decrease the chances of data retransmission at long distance, the IEEE 802.11n Wireless Access Point can automatically adjust proper ACK timeout value by specifying distance of the two nodes. Traffic Shaping It allows the administrator to manage the traffic flow to ensure optimal performance.
46 Figure 18 Traffic Shaping Enable Traffic Shaping Check this box to control the overall bandwidth for a specific VAP network. Interface Selection: Select the VAP network you would like to enable traffic shaping. Outgoing Traffic Rate: To specify maximum outgoing bandwidth to a certain rate in kbit/s. Outgoing Traffic Burst: To specify the buffer size for outgoing traffic that can be sent within a given unit of time. The suggested value is 20KBytes. You may just leave the default value there, and then the connection will be bound to the traffic shaping rule at all times. You may decrease it to smaller value if the incoming traffic limit is smaller. Wireless Security Settings To prevent unauthorized radios from accessing data transmitting over the connectivity, the IEEE 802.11n Wireless Access Point provides you with rock solid security settings.

Legacy 802.1x: Available in AP/Wireless Client mode, it provides the rights to access the wireless network and wired Ethernet. With User and PC identity, centralized authentication as well as dynamic key management, it controls the security risk of wireless network to the lowest. To serve the 802.1x, at least one EAP type should be supported by the RADIUS Server, AP and wireless client. For first time users, if EAP type “TLS” is selected, you need to import valid user certificate given by CA in prior. To import user certificates, please refer to Chapter 5 Management/Certificate Settings for more details. . WPA with RADIUS: Available in AP/Wireless Client mode, with warrant (username, password and etc.) offered by user, this kind of authentication can be realized with specific RADIUS server. This is the common way to be adopted in large enterprise network. WPA2 with RADIUS: Available in AP/Wireless Client mode, as a new version of WPA, only all the clients support WPA2, can it be available. If it is selected, AES encryption and RADIUS server is required. It is only available in AP/Wireless Client mode. WPA&WPA2 with RADIUS: Available in AP mode, it provides options of WPA (TKIP) or WPA2 (AES) for the client. If it is selected, the data encryption type must be TKIP + AES and the RADIUS server must be set. WPA-PSK: It is a simplified WPA mode with no need for specific authentication server. In this so-called WPA Pre-Shared Key, all you have to do is just pre-enter a key in each WLAN node and this is the common way to be adopted in large and middle enterprise as well as residential network. WPA2-PSK: As a new version of WPA, only all the clients support WPA2, can it be available. If it is selected, the data encryption can only be AES and the passphrase is required. WPA-PSK&WPA2-PSK: Available in AP mode, it provides options of WPA (TKIP) or WPA2 (AES) Note:
48 encryption for the client. If it is selected, the data encryption can only be TKIP + AES and the passphrase is required. Data Encryption If data encryption is enabled, the key is required and only sharing the same key with other wireless devices can the communication be established. None: Available only when the authentication type is open system. 64 bits WEP: It is made up of 10 hexadecimal numbers. 128 bits WEP: It is made up of 26 hexadecimal numbers. 152 bits WEP: It is made up of 32 hexadecimal numbers. TKIP: Temporal Key Integrity Protocol, which is a kind of dynamic encryption, is co-used with WPA-PSK, etc. AES: Advanced Encryption Standard, it is usually co-used with WPA2-PSK, WPA, WPA2, etc. TKIP + AES: It allows for backwards compatibility with devices using TKIP. We strongly recommend you enable wireless security on your network! Only setting the same Authentication, Data Encryption and Key in the IEEE 802.11n Wireless Access Point and other associated wireless devices, can the communication be established!
