Getting Started

Setting up the proNX Optical Director to control and manage devices in your network consists of a set of basic steps.

Before using the proNX Optical Director, ensure that the devices in your network have been installed and that they can be reached from the proNX Optical Director. At a minimum, assign each device an IP address and connect it to the management network. As part of installation, you should also connect up the physical fibers that make up your optical network so that you do not have to return to connect them at a later date.

When you log in to the proNX Optical Director for the first time, you will find no devices under control or management. The first step you need to do is to discover the devices that make up your network. You can discover one device at a time or, more typically, you can discover multiple devices based on your discovery selection criteria. As part of device discovery, you will assign the device to a site. This allows the proNX Optical Director to accurately place the discovered device on the map. The proNX Optical Director supports a flexible set of discovery criteria to allow you to discover your devices and assign them to sites quickly and efficiently.

Devices are shipped from the factory with pre-loaded software. If the software version in the devices is not the software version that you want to run, then upgrade the software on the devices after you discover them.

Some devices such as optical multiplexer/demultiplexers are passive, which means the devices are not powered and do not run any software. Multiplexer/demultiplexers are modeled as modules that you explicitly configure and add to ROADM devices. Because multiplexer/demultiplexers are passive, they are not directly discoverable. The proNX Optical Director only becomes aware of their presence when you configure and add them to a ROADM device (or if you discover a ROADM device to which you had previously configured and added a multiplexer/demultiplexer).

Once you have discovered (and/or added) all your devices and assigned them to sites and upgraded the device software if needed, you can then configure the device links in your optical network. Device links represent the physical fibers connecting the devices together. In releases lower than release 2.2, you are required to configure all the device links manually. In releases 2.2 and higher, the proNX Optical Director supports automatic learning of all line spans in the network, so you are only required to configure the device links that are not line spans. It is important that you perform this step correctly because the proNX Optical Director uses the device links to build the ROADM topology of the network. If the constructed topology does not match the actual topology, unexpected behavior can occur.

After the device links are configured and/or learned, the proNX Optical Director constructs an accurate view of the topology and can start supporting optical service creation. If the service you want to create includes the tail facility, then configure the tail facility endpoint before you create the service. The tail facility refers to the connectivity between the endpoint transponder and the optical network. The proNX Optical Director allows you to configure the tail facility endpoint if the tail facility endpoint resides on a supported port on Juniper Networks equipment. See Supported Tail Facility Endpoints for information on supported tail facilities.

Once the tail facilities are configured, you can create the optical services.

The following steps summarize this workflow:

  1. Install the hardware and connect it to the management network. See the TCX1000 Programmable ROADM Hardware Guide and the TCX1000 Inline Amplifier Hardware Guide.

  2. Discover the devices (including the devices at the tail facility endpoints) and add them to sites. See Discovering a Device.

  3. Upgrade the software on the devices as necessary. See Upgrading the Software on a Device for information on upgrading the software on TCX Series devices. To upgrade the software on other devices, refer to the documentation for those other devices.

  4. Add multiplexer/demultiplexers to ROADM devices as needed. See Adding a Multiplexer/Demultiplexer to a Shelf.

  5. Configure the device links. See Creating a Link.

  6. Configure the ports at the tail facility endpoints if you are creating services to supported tail facility endpoints. See Configuring a Port.

  7. Create the optical services. See Creating a Single Path Service and Creating a Protected Service.
