4.1.3
Connecting to the Network
Connect the LAN socket on the top panel of your phone, shown in figure 4-2, to your Local Area
Network. Figure 4-2 displays the location of the LAN socket on the phone
The ZIP2 Ethernet circuit has automatic sensing to determine whether the circuit should operate
at 10 Mb/s or 100 Mb/s. The phone will always attempt to establish connection at the higher rate
and will fall back to the lower rate only if the device to which you have connected the phone
cannot operate at the higher rate.
4.2
Power On
4.2.1
Quick Flash of LEDs at Power Up
When you first provide power to it, the phone quickly flashes twice the red LED above the
keypad and the yellow LED below the keypad. Both LEDs turn off a few seconds after the power
stabilizes. You must ensure that the power plug is fully inserted into the phone. If the power plug
is not fully inserted, the LEDs may flash as normal, but the phone will not be operational and you
will not receive dial tone.
4.2.2
Dial Tone
If you hear dial tone when you pick up the phone, two conditions are true:
•
the phone has power
•
the phone has been assigned an IP address
If you do not hear dial tone and you have properly installed the power and Ethernet cables, ask
the network administrator for assistance.
After receiving dial tone, you will continue to hear dial tone even if the network subsequently fails
or if the Ethernet connection is subsequently removed. Hearing dial tone does not indicate that
the phone can properly communicate with a SIP server, so you cannot make a call unless the
phone can communicate with a SIP server.
4.2.3
Cannot Complete Call
If you hear dial tone, but receive a fast busy tone after you dial a number, the phone has not been
able to communicate with a SIP server.
