Connecting the components
Note 1: Your IP Phone 1140E supports both AC power and Power
over Ethernet options, including IEEE 802.3af standard power. To
use local AC power, the optional AC adapter can be ordered
separately. To use Power over Ethernet, where power is delivered
over the CAT-5 cable, the LAN must support Power over Ethernet,
and an AC adapter is not required.
Note 2: You must use CAT-5e (or later) cables if you want to use
gigabit Ethernet.
3. Install the handset. Connect the end of the handset cable with the
short straight section into the handset. Connect the end of the
handset cable with the long straight section to the back of the phone,
using the RJ-9 handset jack marked with the symbol
bend in the cable, and then thread the handset cord through the
channels in the stand so that it exits behind the handset on the right
side, in the channel exit in the stand base marked with the symbol
as shown in Figure 6A.
