As part of its re-entry into the core switching and routing space, 3Com Corp. last week added the next family member in its Switch 7700 line with a high-availability version.

The Switch 7700R is the second member of the chassis-based LAN switch line to come out of the Marlboro, Mass., company’s joint venture with Huawei Technologies Co. Ltd., of Shenzhen, China. It features a redundant switch fabric that provides 1-second failover in the event the main switch fabric goes down.
