Stacking Ports | MRV Communications MR2228-S2C specification

Stacking Ports

The unit provides two stacking ports that provide a 1 Gbps stack backplane connection. Up to eight switches can be connected together using Category 5 Ethernet cables (purchased separately). The Master button enables one switch in the stack to be selected as the master. This is the unit through which you manage the entire stack.

The stacking ports can also be used as normal Ethernet ports in standalone mode by pressing the Uplink button.
