DIGITAL VNswitch 900LL

This document serves as a comprehensive manual for the DIGITAL VNswitch 900LL module, covering its installation, configuration, and maintenance. The VNswitch 900LL is an SNMP-manageable Ethernet switch equipped with 12 front-panel 10Base-FL 802.3/Ethernet ports and 12 dedicated backplane ports, designed to function as a backbone network switch. It offers advanced features such as comprehensive filtering (source/destination address, protocol type, VLAN), a large address table (approx. 8,000 entries), IEEE 802.1d compliance, and supports hot-swapping and non-disruptive firmware upgrades via flash memory.

The module can be installed in a DIGITAL MultiSwitch 900 chassis or standalone in a DEChub ONE/ONE-MX docking station. Management is facilitated through SNMP, a Command Line Interface (CLI) via Telnet or a local terminal, and the clearVISN MultiChassis Manager GUI. Key configuration steps involve comparing power ratings, physically seating the module, verifying LED operation, and connecting 10BaseFL and LDM port cables.

Configuration procedures are detailed for both DEChub ONE/ONE-MX and MultiSwitch 900 environments. This includes assigning IP addresses (in-band and out-of-band), setting SNMP read/write communities, configuring default gateways, and managing out-of-band port settings (speed, RTS state) through menu-driven interfaces. For MultiSwitch 900 installations, a "Redirect Mode" is used to access the module's specific configuration menu. The manual also provides instructions for viewing and clearing error logs, removing the module, and includes appendices for LED-based problem-solving, detailed connector/adapter specifications, and environmental, power, and acoustical product specifications.
