Description | manage the loop, not the hub

The LH5000 fibre channel hub features patented digital technology that enables unmatched loop resiliency and system availability. With intelligence on every port, the LH5000 provides port isolation, validates loop protocol, and fully re-times the signal. The LH5000 also provides a number of management capabilities, including web-based management.

The digital architecture of the LH5000 eliminates all signal jitter and provides automatic clock speed matching on every port. As a result, LH5000 hubs can be configured as a single 10 port loop or dual independent 5 port loops, allowing for flexibility in network design and cabling distances.

The LH5000 provides a new level of information and control to administrators of fibre channel networks. Per port statistics allow a detailed look at loop status and performance including the number of invalid transmission words, comparative error rates and port down counts.

Driver Support

Remote programmability allows administrators to remotely reconfigure the loop to optimize performance or to diagnose and isolate failures. Remote configuration options include:

• join or separate cascaded hubs, sub-divide loops or join separate loops
• configure as a single 10–port hub or two 5–port hubs for separate FC loops
• force ports to bypass mode
• set hysteresis characteristics of automatic bypass mode
• provide LIP (loop initialization procedure) on hot port insertion
• set bypass on LIP F8 option

Management of the LH5000 digital fibre hub is provided via: an HTML interface which is compatible with most standard web browsers;command line interface through a local console; or Telnet or with SNMP MIB client software.
