WARNING

Use your IP Phone 1140E with the approved Nortel

global power supply (model number NTYS17xxE6).

The IP Phone 1140E supports both AC power and Power over

Ethernet 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

optional global power supply can be ordered separately.

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

Ethernet.
