1. Form a small bend in the cable.
2. Thread the adapter cord through the channels in the stand.
To use PoE, your connected LAN must support PoE. A PoE-enabled LAN
delivers power to your IP Deskphone over the CAT-5 network cable and
an AC adapter is not required.
To use gigabit Ethernet, you must connect to the LAN through CAT-5e (or
later) cables.
Connecting the handset
Use the following procedure to connect the handset to the IP Deskphone.
1. Connect the end of the handset cable with a short straight section to
the handset.
2. Connect the end of the handset cable with the long straight section,
into the RJ-9 handset jack marked with the
+ symbol on the back of
the IP Deskphone.
3. Form a small bend in the cable.
4. Thread the handset cord through the channels in the stand so that it
exits behind the handset on the right side, using the handset cord exit
in the stand base marked with the
+ symbol as shown in Figure 11 on
page 54.
WARNING
If you are connected to a PoE connection do not use the
AC power adapter
