CLUSTERED STACKING

Single IP address and management interfaces for centralized control

Up to 32 devices per cluster across 3Com Switch 4210, 4200G, 4500,

4500G, 4800G, 5500 and 5500G devices

The 3Com Switch 4200G 1-Port 10-Gigabit Module (XFP) 3C17666

shown above adds one XFP-based 10-Gigabit port to the rear of a

Switch 4200G system as a high-bandwidth link for connections to high

speed network backbones or other peer switches or servers. An XFP

transceiver, sold separately, is required to support the desired

connection's fiber media.
