Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

    Introduction

    This document describes how to bypass the Dynamic Host Configuration Protocol (DHCP) requirement when DHCP server is unavailable on MX700/MX800/SX80 that runs CE software.

    Contributed by Ramon Hernández López, Cisco TAC Engineer.

    Problem

    When a newly install MX700/MX800/SX80 or after a factory reset to the codec, the device looks for IP settings via DHCP but if the DHCP option is disabled and you try to insert the IP settings manually, the device rejects the settings and shows a message that states DHCP server cannot be found.

    From the release notes:

    Endpoints always use option 150 in the DHCP request. This is not configurable.

    Solution

    Components needed:

    • Laptop with Putty (or similar software)
    • RS232(DB9)-USB Cable

    Procedure

    Step 1. Connect to the COM port on the codec.

    Step 2. Get the COM port number and set the baud rate to 115200 bps.

    Step 3. Open Putty, select Connection type: Serial, set speed to 115200 and type the COM port number.

    Step 4. Login with the username as admin, and password is not required.

    Enter these commands with the complementary information.

    xConfiguration Network IPv4 Assignment: Static

    xConfiguration Network IPv4 Address: x.x.x.x

    xConfiguration Network IPv4 SubnetMask: x.x.x.x

    xConfiguration Network IPv4 Gateway: x.x.x.x

    After these commands are entered, the device will accept the IP address and moves to the next steps to finish the initial configuration.
