Installation Instructions
Assembling the MC74
The MC74 ships with the handset detached from the rest of the unit. To place calls using the
handset, it will need to be connected to the MC74. To connect the handset, plug the RJ9
connector at the free end of the handset cable into the RJ9 jack located near the bottom of
the unit underneath the stand. Once connected, secure the handset cable using the
magnetic clip on the right hand side of the unit.
Powering the MC74 with an AC Adapter
5.
Plug the Ethernet cable that will be used to provide network access to the MC74 into the
rightmost RJ45 Ethernet jack.
6.
Plug one end of the AC adapter into the MC74 and the other end into a wall outlet.
Powering the MC74 with Power over Ethernet
Route the Ethernet cable from an active port on a 802.3af PoE switch or PoE injector to the
rightmost RJ45 Ethernet jack on the rear of the MC74. To maximize performance, a Gigabit-
capable switch should be used.
Connecting Additional Devices
The MC74 contains a second RJ45 Ethernet jack that can be used to provide network
access to an additional device. To use this port, ensure that the uplink Ethernet cable is
connected and connect the chosen device to the leftmost Ethernet port on the rear of the
MC74. This port does not provide PoE and does not support VLAN tagging.
Verify Device Functionality and Make a Test Call
1.
Verify that the screen displays the dial pad.
2.
If you have not done so already, assign an extension to the MC74.
3.
Make a test call.
6.
Call the number "5000" using the newly installed MC74.
7.
You should be able to hear yourself using both the handset and speaker.
