Figure 3. Connecting the SL4050/10 SIP Phone
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
Plug one end of the Ethernet cable included with the VoIP SIP phone into the LAN port on the SIP
phone (see figure 3 for SL4050/10 or figure 4 on page 23 for SL4050/2). Plug the other end of the cable
into the xDSL modem or cable modem (or into an optional router or hub).
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
If you will not be connecting a PC to the phone, go to step 3. Otherwise, connect an Ethernet cable into
the PC port of the SIP phone (see figure 3 for SL4050/10 or figure 4 on page 23 for SL4050/2). Plug the
other end of the cable into the Ethernet port on the PC.
