• The Down LED for Unit 2 and the Up LED for Unit 4 turn off indicating a connection error
occurred.
• The Stack remains operating with half of the normal bandwidth for Unit 2 and 4, Unit 1
has full bandwidth.
Rear port mode
By default, the Fabric Interconnect (FI) ports on the rear of the VSP 7000 Series are configured
for Stack-mode Distributed Top-of-Rack deployments, leveraging the Flexible Advanced
Stacking Technology (FAST) protocol. Enabling a Rear port mode reboots the unit and re-
configures the FI ports as multiple 40 Gbps Avaya interface ports for use with other protocols.
You can use rear port mode to interconnect multiple stand-alone VSP 7000 units using FI
cables. Depending on the rear port mode of operation either seven or eight 40 Gbps interfaces
are available over the four FI ports on the rear of the switch.
The following table provides detailed information about the FI ports and rear port modes:
FI port Rear port mode Bandwidth Port interface
UP 1 (right top
connector) Standard (Raw-
mode) 120 Gbps 34, 35, 36
UP 2 (right bottom
connector) Standard (Raw-
mode) 40 Gbps 33
DOWN 1 (left top
connector) Standard (Raw-
mode) 120 Gbps 38, 39, 40
DOWN 2 (left bottom
connector) Standard (Raw-
mode) 40 Gbps 37
UP 1 (right top
connector) SPB (Fabric-mode
DToR) 120 Gbps 34, 35, 36
UP 2 (right bottom
connector) SPB (Fabric-mode
DToR) 40 Gbps 33
DOWN 1 (left top
connector) SPB (Fabric-mode
DToR) 80 Gbps 38, 39
DOWN 2 (left bottom
connector) SPB (Fabric-mode
DToR) 40 Gbps 37
On the rear of each VSP 7000 Series unit is a pair of FI-up and FI-down ports. In each FI port
pair there is a top and bottom connector. In rear port mode, each top connector can provide
up to three 40 Gbps ports, and each bottom connector can provide one 40 Gbps port.
You can enable a rear port mode and connect the FI ports between standalone VSP 7000
Series units to deploy in a Fabric-mode Distributed Top-of-Rack (DToR) or Raw-mode
configuration. Fabric-mode DToR leverages the Shortest Path Bridging (SPB) protocol.
