ZIP4x4 User’s Manual
4.1.2.3 Dual Power Sources
If the phone receives power from both the Ethernet port and an ac adapter, it consumes power
only from the ac adapter. You can see what power is applied to the ZIP4x4 using the menu. See
section 9.4.3 on page 117.
If the ac power fails, the phone can take power from a LAN power source and continue to operate.
The length of time that the phone will operate with the power from the LAN is dependent on the
capacity of the battery connected to the power source and the number of phones drawing power.
Using the phone to make a call does not materially change the power used by the phone.
4.1.2.4 When Power is Applied
When you apply power, the phone starts to operate. The ZIP4x4 does not have any power switch.
After the phone is powered up, it displays a message on the screen as shown in section 4.2 on page
26.
4.1.3 Wall or Desk Mounting
You can mount the phone on a wall or on a desk. Install the rear platform that has the two back
feet if you are putting the phone on a desk. Remove this platform (as shown in figure 1-2) if you
want to mount the phone on the wall, and mount it in the lower position.
4.1.4 Connecting to the Network
You normally connect the ZIP4x4 to a LAN or directly to a call control system. The call control
system manages many function for the phone including the ability to originate and terminate a
call, and provides a storage for voice mail. This section briefly describes the process of connecting
the phone to a network.
Section 8.2.9 on page 79 describes the method of directly connecting two ZIP4x4 phones, either
outside of a LAN or isolated within a network.
4.1.4.1 Auto MDI/MDI-X and Auto Negotiation
Each of the four Ethernet circuits on the ZIP4x4 has automatic sensing to determine on which
pins of the RJ45 connector it should transmit data and on which pins of the RJ45 connector it
should receive data. This is referred to as auto MDI/MDI-X.
With this function in the phone, you can use a straight or cross wired cable to connect the phone
to any other device. If you connect the phone to a device that itself has auto MDI/MDI-X, the
devices resolve the appropriate pins to use through random selection.
Also, each of the four Ethernet circuits on the ZIP4x4 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.
4.1.4.2 Single Circuit
Connect the LAN circuit on the back of the phone to the LAN, as shown in figure 4-1.
