  To connect the WAN copper GbE port: 
1.  Connect one end of a straight-through RJ-45 Ethernet cable to the RJ-45 port labeled 
WAN (located on the front panel).

2.  Connect the other end of the cable to the Ethernet WAN network (e.g., ADSL or Cable 
modem). 
 
 
 
 
 
6.2.2  Fiber-Optic Gigabit Ethernet Cabling 
The device supports up to two pairs of 1.25 Gbps optical small form-factor pluggable (SFP) 
transceiver modules.  
Note that SFP modules and fiber-optic cables are not supplied. It is recommended that you 
purchase the SFP modules from AudioCodes. For a list of orderable SFP modules, see 
Appendix  A on page 61, or contact your AudioCodes sales representative. 
 
 
Caution Laser 
This device contains a Class 1 LED/Laser emitting device, as defined by 21CFR 
1040 and IEC825.  Do  not  stare directly into the beam or into fiber optic 
terminations as this can damage your eyesight. 
 
 
Care in Handling Fiber Optic Cabling: 
1.  Excessive bending of the Fiber Optic Cable can cause distortion and signal losses. 
2.  Ensure the minimum bending radius recommended by the Fiber Optic Cable supplier. 
3.  Incoming optic cabling from the network infrastructure can originate from the top of 
the rack or from another shelf within the rack. Preserve the minimum-bending ratio 
indicated by the cable manufacturer. 
4.  To ensure full high-availability capabilities, the configuration of the interface to the IP 
backbone must include certain redundant features from which two separate fiber optic 
cables are entering the device. 
 
 
Note: This AudioCodes device has been evaluated with the laser transceiver modules 
(SFP) listed in Appendix  A  on page 61.  If other SFP  modules are used, the person 
installing the device is solely responsible for the usage of correct SFP modules to comply 
with local, applicable laser safety requirements and certification. AudioCodes will not be 
held responsible for any damage to human body or equipment caused as a result from 
the usage of SFP modules that are not listed in Appendix  A on page 61.
