Figure 1-9. Switch Stack Using 40GbE Ports on Two Aggregators Use only QSFP transceivers and QSFP cables (separately purchased) to connect stacking ports; for example: 1 Insert a QSFP cable in the bottom base-module port on the rightmost Aggregator. 2 Connect the cable to the bottom base-module port on the next Aggregator to the left. 3 On the leftmost Aggregator, connect the top base-module port to the top base-module port on the rightmost Aggregator to create a loop. NOTE: The resulting topology allows the stack to function as a single switch with resilient fail-over capabilities. 30 Assembling a Switch Stack

Assembling a Switch Stack
Figure 1-9.
Switch Stack Using 40GbE Ports on Two Aggregators
Use only QSFP transceivers and QSFP cables (s
eparately purchased)
to
connect stacking ports; for example:
1
Insert a QSFP cable in the bottom base-module port on the rightmost
Aggregator.
2
Connect the cable to the bottom base-module port on the next Aggregator
to the left.
3
On the leftmost Aggregator, connect the top base-module port to the top
base-module port on the rightmost Aggregator to create a loop.
NOTE:
The resulting topology allows the stack to function as a single switch with
resilient fail-over capabilities.
