Connecting a Hybrid System

To follow this guide, your system must be running OneView software version 4.7.0-268 or newer.

Supported Aggregation Switches

These Optigo Edge Switches are the supported for use as the aggregation switch in a Connect Hybrid system:

• ONS-C401i
• ONS-C801pi
• ONS-C810p
• ONS-C2401p
• ONS-C4801p
• ONS-CR2420GT
• ONS-CR2440XP
• ONS-CD0840GP

In all images below, grey ports are RJ45, whereas black ports are SFP slots.

Connecting Edge Switches

Daisy Chain

You can daisy chain edge switches off of the aggregation switch from any SFP port or any port configured with the "discovery" mode VLAN. On the ONS-C810p, port 10, which is an RJ45 port without PoE, can also be used for the daisy chain. When adding a new edge switch to the daisy chain, you must use the OPT port on the newly added edge switch. You can use any free SFP or discovery port to connect from the previous to the newly added edge switch. See the example below.

Ring

Rings are similar to daisy chains, but you connect two daisy chains together at the ends. To make the final ring connection, you can use any free SFP ports or 'discovery' VLAN mode ports (see notes at the bottom) at the ends of the daisy chains. The final ring connections are in red in the example below.

IMPORTANT:
You must not plug in the final connection until all edge switches are registered successfully and spanning tree is enabled in your system.

In the examples shown for rings, edge switches are of the same model for clarity. There is no such limitation in the Connect system - you are free to use any edge switch model, regardless of topology.

Example - ONS-C810p aggregation switch + 2 x ONS-C2401p edge switches

Example - ONS-C401i aggregation switch + 4 x ONS-C401i edge switches

Other Topologies

In version 4.7.0 or newer, OneView also supports arbitrary Hybrid topologies with a mix of RJ45 ports (configured with 'discovery' VLAN mode) and/or SFP ports.

When connecting topologies other than those shown in the examples above, keep the following in mind:

• Using the ONS-C401i, ONS-C801pi, and ONS-C1601pi with 'discovery' VLAN mode is not officially supported, due to their 100 Mbps max link speed on non-SFP ports.
  
  
• When connecting a new Edge Switch, one that has never been connected to the system, the switch's 'OPT' port must be used to register it with OneView.
  
  
• If the design has any redundant connections (e.g. ring or mesh topology), do not connect any redundant connections until all Edge Switches have successfully registered with OneView (i.e. all switches are listed with the correct model name and are "online", not in the "failed" state). RSTP might not be enabled on Edge Switches before they register with OneView, which can cause a network loop if the redundant connections are made too early.
