Expanded Routers — Multiple Frames
NV5256, NV7256-Plus, NV7512, NV8256-Plus, NV8288-Plus and NV8576-Plus router frames can
be interconnected with like frames to form an expanded router with a larger switching matrix.
For example, two NV8256 frames (nominally 256 × 256) can be connected to create a 512 × 512
switching matrix.
When router frames are connected, one frame is designated the master frame. All configuration
and crosspoint information is copied from the master frame to all connected slave frame. This
ensures synchronization of all connected frames. After a frame is designated a slave frame in
UniConfig, any change made to the master frame’s configuration is automatically copied to the
slave frame’s control cards. Slave frame configurations cannot be updated. Their configurations
display in the ‘Configuration’ window, but are inactive. All their partition data are greyed out.
S It is prudent, but not necessary, to configure the main frame before you configure the slave
frames.
How to Set Up Partitions for a Main Router Frame
1 Select the primary control card on the router acting as the master router.
2 From ‘Window’ menu, select ‘Configuration’. The ‘Configuration’ window appears:
Fig. 7-5: Configuration Window (Sample, NV8288-Plus, Master Frame)
If the window does not show an ‘Expansion Configuration’ section, the router frame cannot
be part of an expanded router.
3 Click Read All. UniConfig populates the window with the control card’s current partition
data and Ethernet settings.
4 Choose the ‘Main - Expanded’ radio button in the ‘Expansion Configuration’ section.
Doing so designates the control card as belonging to the master (or main) router frame.
Because of the router’s frame interconnection, the master frame controls all the router’s
