2 Gbps Aggregated Link

Switch

To set up this configuration:

1Add the 1000BASE-T ports on the upper unit to the aggregated link.

2Add the 1000BASE-T ports on the lower unit to the aggregated link.

3Connect the 1000BASE-T port marked ‘Up’ on the upper Switch to the 1000BASE-T port marked ‘Up’ on the lower Switch.

4Connect the 1000BASE-T port marked ‘Down’ on the upper Switch to the 1000BASE-T port marked ‘Down’ on the lower Switch.
