cOS Demo System
Quick Start Guide

Step 1: Connect The System To The AC Mains Power

The demo kit is shipped in a portable standard 19 inches wide 5 RU height telecommunications rack. All the components in the rack come pre-wired. No rewiring is necessary.

Note: Peak system consumption is ~1kW.

1. Let the demo kit sit indoors for at least 2 hours before connecting AC power to avoid condensation build-up inside the rack that could be caused by potential temperature differences between the indoors and outdoors.

2. After the rack has acclimated to the indoor temperature, open the front and the rear doors of the demo kit.

3. Locate the power distribution unit (PDU) at the rear of the kit.

4. Connect PDU to the main source of power.

Result: The demo system launches automatically.

5. Wait at least 30 minutes from power on for the cOS CLI to finish the launch.

Step 2: Connect The System To The Network

The router in the rack labeled NOMAD-GW-XX works as the system’s gateway to the network. It has NAT pre-configured on WAN interfaces, which conceals the internal cOS demo system networking from the operator's network for hassle-free networking integration.

Setup description: two SFP transceivers are pre-installed in router ports #1 and #2. You can use either SFP transceiver to connect the demo system to your network:

• Port #1 is 1Gbps copper SFP-T transceiver.
• Port #2 is 10Gbps SFP+ MMF (multi-mode fiber) transceiver.

Both interfaces are pre-configured with DHCPv4 clients to obtain the following IPv4 configuration from operator's network:

• IPv4 address.
• Network mask.
• Default gateway.
• DNS server IP address (optionally).
  • If DNS server IP is not provided by the DHCP server, the system will attempt to use publicly available DNS servers at 8.8.8.8 and 1.1.1.1.

Note: You can configure static IP address(es) on the router (see optional procedure below).

Optional Step: Configure Static IP Address On WAN Interface

To configure 10Gbps interface follow the instructions:

1. Connect your laptop to the OOB management port on the front panel of the router

2. Configure the static IP to 192.168.88.10/24 on your laptop.

3. Open your web browser and enter the URL http://192.168.88.1/.

4. Log in using the username and password printed on the label inside the front door of the cOS demo kit.

Example:

5. In the left-side menu, navigate to IP → Addresses

6. Click Add New.

7. Configure static IP address and netmask on the SFP28-1 or SFP28-2 interface and click "Apply" or "OK" button.

Warning: You may only configure the SFP28-1 or SFP28-2 interface. Do not change IP configurations of any other interfaces, which could result in breaking system functionality.

1. Add a default route by navigating to IP → Routes in the left-side navigation menu

2. Click Add New.

3. Enter a default route as shown in the example and click "Apply" or "OK" button (replace 10.99.0.1 with the default gateway accessible on the operator's network).

Result: At this point it should be possible to ping the IP address assigned to the WAN interface of the router from your network.

Step 3: Connect PON ONUs

The cOS demo kit comes with a pre-installed and pre-connected PLC splitter on the rear side of the rack.

• The cOS demo system’s optical budget is calculated to allow for directly connecting PON ONUs to the splitter (no additional attenuation is needed).
• Different PON modes for cOS demo kits:

• • Kits with a 1RU Pier-1 OLT shelf are preconfigured to support GPON and XGS PON on the same splitter ports (combo mode).
  • Kits with a Fin SFP-based R-OLT support XGS PON and 10G EPON. By default, Fin R-OLT is pre-configured for XGS PON. Please contact Harmonic if 10G-EPON configuration is needed.

1. Locate the fiber patch cords attached in a plastic bag inside to the rear door of the kit.

2. Connect the ONUs to the splitter using SC/APC-SC/APC fiber patch cords.

Optional Step: Connect DOCSIS CMs ONUs

Setup description:

• cOS demo kit comes without cabling and passives for 6 ft plant.
• The system is preconfigured to work in high split mode by default.
  Requirement: Please make sure your 6 feet plant provides ~40db of attenuation and can support high split spectrum.
  
  
• The demo kit is configured for internal DOCSIS provisioning (DHCP server, TFTP server, example basic binary CM configuration file).

Step 4: Connect CPE

• CPE will be provisioned automatically via DHCP
• System is configured to NAT CPEs to the Internet
