WARNING

Use your IP Phone 1120E with the approved Nortel

global power supply (model number NTYS17xxE6).

The IP Phone 1120E supports both AC power and

Power over LAN options, including IEEE 802.3af

Power Classification 3. To use Power over Ethernet,

where power is delivered over the CAT5-e cable, the

LAN must support Power over Ethernet, and a global

power supply is not required. To use local AC power,

the global power supply can be ordered separately.

You must use CAT5-e (or later) cables if you want to

use Gigabit Ethernet.
