Cisco TelePresence SX20 Quick Set  Administrator Guide
Connecting the Touch 10 user interface
In order to use Touch 10 as user interface for the SX20 
codec, Touch 10 must be paired to the codec via the network 
(LAN). This is referred to as remote pairing.
Connecting Touch 10 to the codec via LAN
Connect Touch 10 and the codec to the network wall socket 
or network switch as illustrated.
Touch 10 set-up 
Once Touch 10 is connected to power, the set-up procedure 
begins. Follow the instructions on screen.
When the Select codec to pair with dialog appears, note the 
following:
•  A list of codecs signalling that they are available for paring 
will show up in the dialog. Tap the name of the codec you 
want to pair to followed by Start Pairing. 
Note that the following must be fulfilled for a codec to 
show up in the list:
•  The codec and Touch 10 must be on the same 
subnet.
•  The codec must have been restarted within the last 
10 minutes. If your codec does not appear in the list, 
try restarting the codec.
•  If your codec does not appear in the list of available 
codecs, you can pair the devices manually. Click Select 
codec manually..., enter the IP address or host name of 
the codec, and tap Start Pairing.
•  You have to enter the codec’s administrator username 
and password for the paring to commence.
If Touch 10 needs software upgrade, new software will 
be downloaded from the codec and installed on the unit 
automatically as part of the set-up procedure. Touch 10 
restarts after the upgrade.
You can verify that Touch 10 is successfully connected to the 
codec by checking that the codec address is displayed in the 
top banner.

  If the network infrastructure provides 
Power over Ethernet (PoE), you do 
not need a PoE injector; Touch 10 
should be connected directly to the 
wall socket (Ethernet switch) with a 
PoE rated Ethernet cable.
  For safety, the PoE source must be 
in the same building as Touch 10. 
The PoE rated Ethernet cable can be 
up to 100 m (330 ft).
