Standard-N Male Plug 8 ZyAIR G-5100 3 Wrap a waterproofing strip around the base of each of the antenna connectors on the top of the ZyAIR 4 Connect the supplied antennas to the top antenna connectors (these are for the ZyAIR's WLAN 1 adapter). When facing the rear of the ZyAIR, the left antenna (main antenna) transmits and receives, the right antenna (receive diversity antenna) only receives. Transmitting (Tx) Receiving (Rx) Note: Securely fasten the antennas. 5 Connect the antenna cable to the bottom antenna connector (for the WLAN 2 adapter). This WLAN adapter is recommended for use with bridging applications. Note: Securely fasten the antenna cable. 5. 2 Grounding A safe grounding system is necessary to protect your ZyAIR from lightning strikes and the build-up of static electricity. Direct grounding of the antenna mast, ZyAIR and surge arrester are very important. The ZyAIR's frame ground (see Section 2) should be connected to the same grounding system as the antenna mast and the AC wall outlet. The grounding system must comply with the National Electrical Code and safety standards that apply in your country. Always check with a qualified electrician if you are in doubt as to whether your ZyAIR is properly grounded. 5. 2. 1 Additional Lightening Protection 9 ZyAIR G-5100 Lightning can still damage the ZyAIR, even with the built-in protection. This can occur for any number of reasons, such as an improperly grounded installation or if the amount of transient energy from nearby lightning exceeds what the devices can handle. An external, reverting protection device can provide a higher level of protection, and greater probability of surviving lightning strikes without damage to the ZyAIR. 5. 3 Mounting the ZyAIR Mount the ZyAIR on an antenna mast or a wall. A wall mount may be convenient for AP applications when the roof overhang is not excessive and/or the location is high enough to provide a clear line of sight. In most bridge applications, a wall mount will not allow you to properly align the antenna with the corresponding antenna at the opposite end of your wireless link. As poor alignment will typically result in poor performance, it is advised that you mount the ZyAIR to a mast. Use the included mounting hardware when installing the ZyAIR. Note: The mast or wall-bracket must be free from any substance that may prevent a good electrical connection with the antenna, for example, paint. 5. 3. 1 Mounting Hardware 1 Wall Mounting Bracket 2 Mast Mounting Bracket 3 Installation Tool (wrench) 4 U Bolt 5 Anchor Bolt 6 Screw 7 Washer 8 Split Lock Washer 9 Nut 5. 3. 2 Mast Mounting To accommodate the ZyAIR, the mast must satisfy the following requirements: · The construction of the mast must be of a sturdy, weatherproof and non-corrosive material, for example, galvanized or stainless steel construction pipe. · Typical diameter of the mast should be between 37. 5mm ~ 62. 5mm (1. 5" ~ 2. 5"). Subject to the type of mast that you intend to install, other diameters are possible. · The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1. 5 m (5') above the peak of the roof (or at least 3m (10') if the roof is metal. 10 ZyAIR G-5100 Do the following to mount the ZyAIR on a mast. 1 Insert the U-bolt into the mast-mounting bracket and attach it using two washers, two split lock washers and two nuts. 2 Align the top two holes in the back of the ZyAIR with the holes in the first mastmounting bracket. [. . . ] If all of the power injector LEDs are off, check the cables between the ZyAIR and your computer or hub. Make sure the wireless adapter on the wireless client is working properly. Check that both the ZyAIR and wireless client(s) are using the same SSID, channel and WEP keys (if WEP encryption is activated). 12 ZyAIR G-5100 Problem Cannot access the ZyAIR from the LAN. Corrective Action Check the cable connections between the ZyAIR, the power injector and your computer or switch. [. . . ]
