You must enable a rear port mode, and then connect the rear FI ports between multiple stand-alone
VSP 7000 Series units. Due to the different bandwidth support of the FI ports, connect the top FI
port to the top FI port of another unit, and connect the bottom FI port to the bottom FI port of another
unit.
Figure 21: Fabric-mode DToR cabling example
LACP and VLAN tagging is automatically enabled for the rear ports. Rear port mode allows the VSP
7000 Series to automatically aggregate multiple connections between adjacent units in Fabric-mode
DToR or rear port Raw-mode without additional configuration.
Installing FI cables
Deploying in a Stack-mode DToR, Fabric-mode DToR, or rear port Raw-mode requires the
installation of FI cables to interconnect VSP 7000 Series units. The length, routing, and number of FI
cables required varies depending on your FI configuration. For Stack-mode DToR configurations or
vertical Stack configurations, Avaya recommends that you use the redundant FI-down cable
configuration.
Use the following procedure steps to install Fabric Interconnect cables onto VSP 7000 Series units.
Before you begin
You must have enough FI cables to interconnect the units. See Fabric Interconnect on page 39.
Note:
For Stack configurations, consider each pair of FI ports on a unit as a single connection. Each
pair of FI ports requires two FI cables. Ensure to order a minimum of two matched FI cables for
each unit. For a redundant configuration, you require one matched pair of longer FI cables to
complete the loop from the bottom unit to the top unit.
About this task
Procedure
1. Choose and configure the Fabric Interconnect configuration for your deployment.
2. Connect each FI cable to an FI port. Route the cables between units to support your chosen
FI configuration.
Important:
You must orient each cable so that the alignment slot on the FI cable connector is facing
up and aligns with the alignment tab on the FI port. Verify that the cable is inserted
