Harmonic MediaGrid Release 4.1
Configuring the Network Switches
Once you have configured your network switches, continue to
Getting Started with the Harmonic
MediaGrid Configuration Assistant
for instructions on running the Harmonic MediaGrid Configuration
Assistant, the on-screen method for configuring a Harmonic MediaGrid system.
The Configuration Assistant is a Q&A script that prompts you for Harmonic MediaGrid information
specific to your site. The Configuration Assistant files are located on the ContentDirectors. The
information you provide is used to populate the Harmonic MediaGrid configuration files with the
specific customer information.
NOTE:
The procedures outlined in this section are written for qualified technical personnel, skilled at
advanced networking procedures. If you have any questions, please consult with your facility’s network
administrator or contact Technical Support.
Configuring the Network Switches
Before configuring your Harmonic MediaGrid system, you must configure your network switches.
If you are using 1GbE switches provided by Harmonic for an all-1GbE network, you can use the
Network Configuration Assistant, a stand-alone utility, described in this section.
Note the following:
The Network Configuration Assistant cannot be used for any non-Harmonic MediaGrid-
qualified switches or for any 10GbE switches. For help with configuring those, contact
Technical Support or your network administrator.
The Network Configuration Assistant generates all switch configurations based upon a /24
(Class C) address-space. If you need any other address type, the IP/Netmask values must be
modified manually after the configuration file is generated. For assistance, contact Technical
Support or your network administrator.
The Network Configuration Assistant asks a number of configuration questions and uses the
information to populate switch configuration files located on the ContentDirector. These files can
then be copied to your switches.
Before you begin:
Make sure you have reviewed the
Harmonic MediaGrid Installation Planning Guide
and
completed the configuration worksheet included in that document before running the
Network Configuration Assistant.
Make sure the system is cabled completely.
Make sure you have a USB drive on hand.
To run the Network Configuration Assistant:
1. Connect a monitor and keyboard to the first ContentDirector.
2. Log on to the ContentDirector using the following user name and password:
User name: ovnuser
Password: OVN@SvCaUsa
3. Enter the following at the command prompt:
