Emulex Fibre Channel Hubs
Overview
Features | Management
The LH5000 is a 10 port Fibre Channel hub with built in intelligence. There are two versions:
- The GBIC model has 8 GBIC ports in the front and 2 DE-9 copper ports in the back.
- The copper model has 8 DE-9 copper ports in the front and 2 DE-9 copper ports in the back.
By default, the digital hub is configured as a single 10 port hub. Using the management options the hub can be configured as two separate five port hubs. The ports are ordered in the following manner: port 1 is the upper left front port and following to the right are ports 2, 3, and 4. Port 5 is the upper back port and similarly ports 6, 7, 8, and 9 are the front bottom ports from left to right and port 10 is the back bottom port.
Features
- 10 hot-cascadeable ports in a half width, 1U high standard 19 inch rack.
- 10 copper ports or 8 hot-pluggable GBIC ports and 2 copper ports.
- Configurable as a single ten port hub or two 5 port hubs for separate FC loops.
- Full re-timing of incoming data using an internal oscillator.
- Elimination of jitter transfer which permits nearly unlimited cascading of Digital Hubs.
- Automatic isolation of faults, correction of error conditions, and management statistics on a per port basis.
- Improvement of arbitrated loop stability and reliability through programmable port bypass criteria.
- Non-disruptive insertion and removal of fibre links.
- Manual port bypass via the management interface.
- Full support of Serial ID for GBIC module.
- LED indication for port status on a per port basis.
- Hub management with command line interface via direct console or Telnet connection.
- Hub management with a web browser interface via Ethernet connection.
- Hub management with an SNMP MIB client software.
- Management software is user-upgradable as Emulex releases improved versions.
Management
The LH5000 provides port management and monitoring via two types of connections -
- Console (RS232 and RJ12) serial data
Supports command line interface
- 10BaseT Ethernet (RJ45) port.
Supports command line interface, web manager and SNMP MIB
Each interface provides security against unauthorized configuration changes: The command line and web interfaces require a password before a change is effected. SNMP requires the client to be a member of a write-enabled SNMP community.
The command line interface requires a understanding of the command set and command structure. The web manager has a friendly GUI interface which executes HTML code through web browsers. The SNMP MIB interface is compatible with major SNMP management systems such as OpenView and NetView.
