Step 1: Remove the stand cover. Pull upward on the center catch as indicated in Figure 3, 
and remove the stand cover. The cable routing tracks are now accessible.
Step 2: Connect the AC power adapter (optional). Connect the adapter to the AC adapter 
jack in the bottom of the phone. Form a small bend in the cable, and then thread the adapter 
cord through the channels in the stand. 
Warning: Use your IP Phone 1140E with the approved Nortel AC adapter (model 
#N0023000) for this model of phone only.
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.
Step 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 +. Form a 
small 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 Handset cord exit marked with the 
symbol +in the stand base, as shown in Figure 3.
Step 4: Install the headset (optional). If you are installing a headset, plug the connector 
into the RJ-9 headset jack marked with the symbol )on the back of the phone, and thread 
the headset cord along with the handset cord through the channels in the stand, so that the 
headset cord exits the channel marked with the symbol ).
Step 5: Install the Ethernet cable. Connect one end of the supplied Ethernet cable to the 
back of your phone using the RJ-45 connector marked with the symbol %, and thread the 
network cable through the channel marked with the symbol %. 
Step 6: Install the Ethernet cable connecting the PC to the phone (optional). If you are 
connecting your PC Ethernet through the phone, connect one end of the PC Ethernet cable 
to your phone using the RJ-45 connector marked with the symbol (, and thread it through 
the channel marked with the symbol (. Connect the other end to the LAN connector on the 
back of your PC.
Step 7: Install additional cables. If applicable, plug in optional USB devices. Connect the 
Ethernet cable to the LAN Ethernet connection. If you are using an AC power adapter, plug 
the adapter into an AC outlet. 
Step 8: Wall-mount your phone (optional). Your IP Phone 1140E can be mounted either 
by: (Method A) using the mounting holes on the bottom of the phone stand, or (Method B) 
using a traditional-style wall-mount box with RJ-45 connector and 15-cm (6-inch) RJ-45 cord 
(not provided).
Complete steps 1-7, as needed, before you wall-mount your phone:
Method A: Press the wall-mount lever, and pull the phone away from the stand, as shown in 
Figure 5.Using the stand cover (the part you removed in step 1), mark the wall-mount holes 
by pressing the bottom of the stand cover firmly against the wall in the location where you 
wish to install the phone. Four small pins on the bottom of the stand cover make marks on 
the wall. Use the marks as a guideline for installing the wall-mount screws (not provided). 
Install the screws so that they protrude 3 mm (1/8 inch) from the wall, and then install the 
phone stand mounting holes over the screw heads as indicated in Figure 4 (Method A). You 
may need to remove the phone from the wall to adjust the lower screws. When the lower 
screws are snug, install the phone on the mounting screws, and then tighten the top screws.
Method B: Attach the 15-cm (6-inch) CAT5e cable, position the stand over the mounting 
rivets, and slide the phone down the wall so that the rivets fit into the slots on the stand, 
indicated in Figure 4 (Method B).
Step 9: Replace the stand cover. Ensure that all cables are neatly routed and press the 
stand cover into place until you hear a click.
Step 10: Put the phone in the wall-mount position (optional). If you wall-mounted your 
phone, put it in the wall-mount position by holding the Tilt lever and pressing the phone 
towards the base until the phone is parallel with the base. Release the Tilt lever and 
continue to push the phone towards the base until you hear an audible click. Ensure the 
phone is securely locked in position.
