1-2 Product Introduction
What Is the DIGITAL VNswitch 900FF?
The VNswitch 900FF (also referred to in this manual as the module) is a high-
throughput, Simple Network Management Protocol (SNMP) manageable, multiport
network switch for linking Fiber Distributed Data Interface (FDDI) backbones. It
provides switching for two high-speed FDDI networks.
The module supports the front-insertable Mod-FDDI cards, which are part of the
Modular Media Interface (MMI) family. The Mod-FDDI cards offer either multimode
fiber (MMF) or single-mode fiber (SMF) on SC-type connectors, and unshielded
twisted-pair (UTP) connectors.
The module is auto-configured to connect to the 400 Mb/s VNbus with autoconnect
enabled in the DIGITAL MultiSwitch 900 Chassis Manager (formerly DEChub 900
MultiSwitch Hub Manager). The VNbus provides interoperability across the
DIGITAL MultiSwitch 900 backplane with other VNswitch modules while
maintaining front panel connectivity. Additionally, each of the module’s ports can be
individually redirected to a DIGITAL MultiSwitch 900 backplane LAN segment.
The module includes a large address table (approximately 8000 entries) and is fully
IEEE 802.1d standards-compliant, ensuring the high performance and packet integrity
that is required in large switched networks.
The VNswitch 900FF 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.
You can configurethe module into the DIGITAL MultiSwitch 900 (also referred to in
this manual as the MultiSwitch 900) or as a standalone unit into a DEChub ONE or
DEChub ONE-MX docking station. (See the DEChub ONE Installation manual or
DEChub ONE-MX Installation manual.) The module is fully interoperable with other
modules (including MultiSwitch 900 modules) when installed into a MultiSwitch 900
chassis.
