    Figure 2-3 Core Configuration Manager Create a Link-Group Before linking units together, one LQ device must first be designated as the Link- Master. This is accomplished by setting that device's role to Link-Master. Every other LQ device within the Link-Group will then be set into a Link-Member role which allows the linking of those units directly to the Link-Master.

  • Page 32: Linking

    Linking A Link-Group • A Link-Group can contain up to 6 LQ devices • A Link-Group must have one unit designated as Link-Master • The Link-Group performs a “best effort” approach to creating a mesh network between all the devices within the group. Once joined to the Link-Group, all devices attempt to connect to all other devices within the group.

  • Page 33: The Link-Member Role

    Note: The Link-Master must be reachable on TCP port 80 by all devices within the Link- Group. Reachability of the Link-Master on TCP/UDP port 655 facilitates the routing of audio to/from the Link-Master but is not mandatory when setting up a Link- Group.

  • Page 34: Linking Over Internet Or Wan

    Linking over Internet or WAN When linking over Internet or WAN, the IP addressing of the units becomes more complicated because the units use external addressing and port-forwarding to navigate firewalls.

    Internet connectivity LAN,WAN, Internet Link-Master Link-Member External (public) IP All devices within a Link-Group must have connectivity to the Link-Master on TCP port 80. When linking devices over the Internet, make sure that this connectivity is stable. Internet connection to an LQ device requires special configuration within your firewall (port-forwarding).

  • Page 42: How To Configure The Link-Master To Be Externally Reachable

    How to configure the Link-Master to be externally reachable Both the external IP address and the audio port forwarded within the firewall will need to be configured within the Link-Masters device configuration page. 7.3.1 Set Link-Master external IP address Navigate to the Link-Master's network configuration page by clicking on the Link-Master device in the Overview page and then the Network button.

  • Page 43: How To Configure Link-Members To Be Externally Reachable

    How to configure Link-Members to be externally reachable Clear-Com recommends that all units in a Link-Group are reachable over the Internet. In some cases this will mean external (public) addressing of the Link- Members in a group as well as the Link-Master. This prevents a loss of service if the master is unobtainable for any reason and creates more efficient audio routing.

    Link-local environments • Any networked device will enter link-local mode if it is set to DHCP and no DHCP server is detected on the network. Link-local mode • If both the laptop and the LQ device are in DHCP mode, they will revert to link-local when connected.

  • Page 46: Network Configuration

    Network configuration Dynamic host configuration protocol (DHCP) configuration The default method for LQ devices to obtain an IP address is DHCP and this is the preferred method when setting up a Link-Group over a LAN. Most networks allocate IP addresses using DHCP. The addresses provided are dynamic and will change from time to time.

    9.2.2 Gateway Entry of this setting is optional. You will use it if setting up a Link-Group to navigate across subnets. If it is not explicitly stated, the system will revert to the device IP address. Configuring an external IP address You will use an external or public IP address when routing LQ devices over firewalls (this will almost always be the case when connecting over the Internet).

  • Page 64: Upgrading Your Device

    In order to upgrade your device, you will need to import the upgrade file provided by Clear-Com into the device via the unit’s CCM (Core Configuration Manager). An LQ unit must be upgraded from the host device (the device that the browser is currently addressing).

  • Page 65: Faqs

    FAQs 14.1 How can I find the IP address or name of my LQ unit? The name and IP address of an LQ device can be found on the front panel display of the units and also in the Web GUI. The IP address and name of a unit can only be changed via the CCM (Web-based Core Configuration Manager).

  • Page 66: What Does A Persistent Flashing Green Light (More Than 2 Minutes) On The Front Panel Keypad Indicate

    2 minutes, and the display screen does not move beyond the Clear-Com splash screen, the most likely explanation is that the unit does not have enough power. This can happen if too many LQ devices are drawing power from the same PoE switch or network.

  • Page 74: Terminology/Glossary

    A 4-wire circuit gives a full-duplex interface which is often used to connect to 3 party devices. When used with the LQ Series, a 4-wire direct connection (as opposed to a channel) provides point-to-point and panel connections over IP. The 4-wire direct interface will pass panel data as well as audio.
