Solution
The SecureStack A2, similar to the SecureStack C2 and B2 products, may be stacked up to eight units high for purposes of unified management, in a closed-loop pattern for stack cable redundancy or daisy-chained with the "closing" stack cable omitted (
5668).
The functional and management aspects of stacking are similar on all of the SecureStack products as well, with all management tasks handled via the elected Management unit.
A notable difference is that, though C2 and B2 units have two rear-mounted dedicated stacking connectors and use special stacking cables, each A2 has two front-mounted 1000Base-T RJ45 ports, labeled '25/Up' & '26/Down' on the A2H124-24(P) and '49/Up' & '50/Down' on the A2H124-48(P), which may be used for either 1000Mb Stacking or 10/100/1000Mb Network connectivity using standard Cat5 or higher grade 8-conductor RJ45 straight-through cables (
not included as part of a switch purchase). In either mode, these ethernet cables may be up to 100 meters in length (
4875), making it possible to establish a distributed A2 stack with widely separated member units.
By default, these two RJ45 ports function as Stack ports. For standard 10/100/1000Base-T functionality, issue the cli command 'set switch stack-port ethernet'.
A2(su)->set switch stack-port ethernet
This command will reset the entire system.

To return to the default Stacking function, issue the command 'set switch stack-port stack'.
See 5463 for serial console connection instructions.
