1-2 Product Introduction
What Is the DIGITAL VNswitch 900EE?
The VNswitch 900EE (also referred to in this manual as the module) is a 24-port
Simple Network Management Protocol (SNMP) manageable Ethernet switch,
providing full-speed switching capability between each of its twenty-four 10BaseT
802.3/Ethernet ports.
All of the module’s 24 front-panel 10BaseT 802.3/Ethernet ports are auto-configured
to connect to the 400 Mb/s VNbus on the DIGITAL MultiSwitch 900 (formerly
DEChub 900 MultiSwitch) backplane. Alternatively, as many as 12 ports can be
individually redirected to a MultiSwitch 900 backplane channel (LAN segment) to
form a backplane LAN.
The VNswitch 900EE network module is a true backbonenetworkswitch that supports
complete filtering capabilities (including source address, destination address, protocol
type, and VLAN) for greater network control, increased security and bandwidth
utilization, and reduced propagation of network problems.
The module includes a large address table (approximately 8,000 entries) and is fully
IEEE 802.1d standards-compliant, ensuring high performance and packet integrity
required in large switched networks.
The VNswitch 900EE module also offers nonvolatile flash memory for easy, non-
disruptive upgrades of the device firmware using Trivial File Transfer Protocol
(TFTP) load protocol. This eliminates the need to replace or upgrade hardware in the
future, and avoids the associated costs and disruption to network users.
When installed into a DIGITAL MultiSwitch 900 (also referred to in this manual as a
MultiSwitch 900) and connected to the VNbus, the module can function as an
expansion module for any of the other VNswitch 900 series modules.
You can install and configure the module in a MultiSwitch 900 or as a standalone unit
in a DEChub ONE or DEChub ONE-MX docking station (see the DEChub ONE
Installationmanualor theDEChubONE-MXInstallationmanual). Themoduleisfully
interoperable with other modules when installed in the MultiSwitch 900 (including
both MultiSwitch 900 and DEChub 90 modules).
Throughout this manual, the term DEChub ONE refers to the DEChub ONE or the
DEChub ONE-MX docking station unless otherwise specified.
The VNswitch 900EE module does not support the Fiber Distributed Data Interface
(FDDI) features of the DEChub ONE-MX docking station.
