ServerNet Wide Area Network (SWAN 2) Concentrator
The SWAN 2 concentrator is a next-generation SWAN concentrator. The SWAN 2
concentrator is a communications device that connects bit-synchronous, byte-
synchronous, and asynchronous devices to NonStop S-Series servers. The SWAN 2
concentrator enables customers migrating from NonStop K-series servers to NonStop
S-Series servers to preserve their investment in legacy devices.
The SWAN 2 concentrator is based on a faster processor. Some of the SWAN 2
concentrator’s features are:
•
Modularity
•
Redundant power
•
Two-line fault zone
•
Increased throughput and availability
•
Online-replaceable hardware components known as customer-replaceable units
(CRUs)
