1 Product Overvi ew Thank you for using the ENH500. It is a powerful and enhanced business-class pr oduct with 4 multi-functions: Access P oint, Clie nt Bridge, WDS, and Client R outer . EnG enius’ E NH500 uses the latest wireless standa rd, 802.11n, which allo ws for faster wireless throughput.
d) Frequently alt ered environments Show r ooms, meeting r ooms, ret ail st or es, and manufacturing sites are prime examples where frequently r earranged workplaces are suited for wireless L ANs.
1.2 Benef its Access Point Mode Use this feature to setup the access point’ s conf iguration information. It supports transmit power and channel adjustment s. Clients can ac cess the network with differ ent regulat or y set tings and automat ically change to the local r egulations.
1.3 P ackage Content s Open the package car efully , and make sur e that none of the it ems listed below ar e missing. Do not discar d the packing materials; in ca se of r eturn, the unit must be shipped in its original pac ka gi ng . (1) Wireless Access Point / Client Bridge (ENH 500) (1) 24V/1.
1.6 Understanding the ENH500 LEDs The rear o f the ENH500 has two grou ps o f LEDs. One group, labeled INDICA T ORS , shows the status o f the device. The second group, LINK QU ALITY , shows the strength of the link between the ENH500 and the network .
2 Installation This chapter describes how to install the ENH500. Only experienced installation pro fessional s who are familiar with local building and safety codes and, wher ever applicable, are lic en sed by the appropriate gov ernment regulatory authorities should install the ENH500.
6. Turn ove r the ENH5 00. Then insert th e ma st strap through the middle hole of the ENH500. Use a s crewdriver to unlock the po le-mounting ring putting it through the ENH500. 7. Mount the ENH500 securely to the po le by locking the strap tightly. This completes the in stallation procedure.
client s that suppor t the IEEE 802.11a/n st andard s. S tations and client s mus t utilize the same SSID and Security P assword to a ssociate while wi thin range.
Not ever y Access Point suppor ts WDS in Access P oint Mode. It is recommended to use ENH500s if you would like to utilize this functionalit y . 3.3 Client Bridge Mode In the Client Bridge Mode, the ENH500 functi ons lik e a wir eless client, connecting t o an Access P oint wirelessly and enabling Internet co nnectivity wher ever you want.
3.4 WDS Bridge M ode In the WDS Bridge Mode, the ENH500 can wirelessl y connect different local area networks by conf iguring each device’ s MAC addr ess and se curity settings. The WDS Bridge Mode can bridge up to four local wired networks together as one l ogical network .
WDS Bridge Mode is un like Access P o int Mode. APs linked by WDS are using the same wireless channel, and connecti ng excessive numbers o f APs on the same channel may result in lower throug hput. Please be aware to avoid loop connections; other wise enable the Spanning T ree Function.
