Which of the following statements is correct about connecting a Cisco TelePresence Touch 8″ directly to a
codec?
A.
Direct pairing must be enabled on the Touch 8″.
B.
Pairing visibility mode must be enabled on the Touch 8″.
C.
The Touch 8″ must be connected to the codec’s first Ethernet connector.
D.
The Touch 8″ must be connected to the codec’s second Ethernet connector.
Explanation:
The Touch 8″ must be connected to the codec’s second Ethernet connector. You can connect a Cisco
TelePresence Touch 8″ to a codec over the LAN or by a direct connection to the codec. To directly connect to a
codec, perform the following steps:
1. Connect the codec’s first Ethernet port to the LAN.
2. Enable direct pairing on the codec, and then reboot the codec to activate direct pairing.
3. Connect the touch screen cable to the power adapter.
4. Connect the Ethernet cable between the power adapter and the codec’s second Ethernet port.
5. Connect the power cable between the power adapter and the wall socket. The touch screen will initialize
and then download and install software from the codec, if necessary.
6. Verify that the codec address appears in the top banner.
To connect to a codec over the LAN, perform the following steps:
1. Restart the codec in order to activate pairing visibility mode.
2. Connect the touch screen cable to the power adapter.
3. Connect the Ethernet cable between the power adapter and the LAN.
4. Connect the power cable between the power adapter and the wall socket. The touch screen will initialize
and obtain IP addressing information from Dynamic Host Configuration Protocol (DHCP).
5. Select the codec name in the list, and then select Start Pairing. The touch screen will download and install
software from the codec, if necessary. If the codec is password-protected, you must enter a valid user name
and password.
6. Verify that the codec address appears in the top banner.
If the codec does not appear in the list of codecs, you should perform the following steps:
1. Ensure that pairing visibility mode is active on the codec.
2. Ensure that the codec and the touch screen are on the same subnet.
3. Select the codec manually by entering the codec’s IP address or host name.
Direct pairing must be enabled on the codec, not on the Touch 8″, when connecting a Touch 8″ directly to the
codec. Pairing visibility mode must be enabled on the codec, not on the Touch 8″, when connecting a Touch 8″
to the codec over the LAN. The codec’s first Ethernet port should be connected to the LAN, not to the Touch 8″.Cisco: Cisco TelePresence Touch 8″ Installation Guide (PDF)
