MC74 Installation Guide

MC74 Overview

The Cisco Meraki MC74 is an enterprise class collaboration endpoint designed for ease of management and remote administration. It is ideal for administrators who want to quickly and easily deploy and manage distributed phone systems. The MC74 provides the following hardware features:

  • A 7" full color touch screen display
  • Two Ethernet ports for connecting the phone and an additional device such as a PC
  • Two USB ports and a 3.5mm jack for headsets
  • One RJ9 port for connecting the included handset

Ethernet ports

The MC74 features two Gigabit Ethernet RJ45 ports. One of these ports is used as an uplink and accepts 802.3af power over Ethernet (PoE). This port should connect to your internal network (LAN). The second port is a passthrough port that provides Gigabit connectivity to a second device such as a PC.

Power Source Options

The MC74 can be powered using a Meraki MC AC adapter (MA-PWR-18W), PoE injector, or a PoE switch.

LED Indicators

The MC74 is equipped with a single multi-color LED in the top right corner of the unit in addition to the touch screen display. This LED will display a rainbow pattern while the unit is booting up, flash green when a new VM has been received and flash red when a call has been missed.

Pre-Install Preparation

You should complete the following steps before installing the MC74 in its final location.

Configure your Devices in Dashboard

The following is a brief overview only of the steps required to add an MC74 to your network.

 

  1. Login to http://dashboard.meraki.com. If this is your first time, create a new account.
  2. Under Organization -> Create network, create a new Phone network.
  3. Add your phones to your network. You will need the serial number of each phone, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the stand attached to the unit.
  4. Optionally, go to the map / floor plan view and place each phone on the map by clicking and dragging it to the location where you plan to deploy it.
  5. Please go through the configuration steps listed in our Onboarding Service Providers page to receive phone numbers.
  6. Please go through the configuration steps listed on our Creating and Managing Extensions page to assign these devices to contacts and numbers.

Upgrade your Devices

The first time an MC74 unit is powered on, it will reach out to the Meraki Cloud to download the latest firmware updates. To ensure that this process completes successfully, please follow the steps below.

  1. Ensure that the device has been added to a Dashboard network as described above.
  2. Configure your firewall as described in the Network Configuration article.
  3. Plug the phone into an Ethernet cable connected to your LAN using the rightmost Ethernet port.
  4. Your phone will power up and display the phrase "Starting Dialer". Once this message appears, leave the phone online for 10-30 minutes while it completes the upgrade process. The exact duration of the upgrade will vary based on your internet connection.
  5. Once the phone has finished upgrading, it will display a dial pad on screen. Once you reach this screen, the upgrade process is complete and the phone can be deployed.

Assigning IP Addresses

At this time, the MC74 does not support static IP assignment. MC74 units must be added to a subnet that uses DHCP and has available DHCP addresses to operate correctly.

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

  1. Plug the Ethernet cable that will be used to provide network access to the MC74 into the rightmost RJ45 Ethernet jack.
  2. 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.
    1. Call the number "*###" using the newly installed MC74.
    2. You should be able to hear yourself using both the handset and speaker.
    3. When you are finished testing, simply hang up.

 

The phone will indicate connectivity status in the top status bar where the time is located. Connectivity status indicators are explained below:

 

Network Status

Possible Causes

Phone Indicator Behavior

Phone is unable to retrieve a DHCP IP address.

  • The phone is not receiving a response to DHCP DISCOVER messages which could indicate a problem with the local DHCP server

  • The upstream switch port could be configured on a VLAN where DHCP is not present

 

 

The phone is unable to register with the Cisco Meraki cloud platform

  • The phone has retrieved a local IP address but cannot contact the MC platform

  • Ensure that outbound firewall rules have bee established as per the Firewall Info document located in Dashboard Help.

 

 

The phone has successfully connected to the MC platform

After this setup has been completed, your phones should be online, associated with phone numbers, and assigned to contacts.
