Model 3301 Ethernet Host Module

The Model 3301 Ethernet Host Module provides connectivity over coaxial cable. This module can be combined with other 10BASE-T Ethernet modules, as well with token ring and FDDI modules, in System 3000 hubs.

Allows 10BASE2 thin coaxial cabling to be arranged in a fully managed, physical-star topology.
Modular design simplifies installation of various Ethernet cabling systems.

Model 3304A Ethernet Host Module

The Model 3304A Ethernet Host Module provides Ethernet connectivity over fiber-optic cable. The host module offers eight 10BASE-F ports, and can be combined in System 3000 hubs with 10BASE-T Ethernet, token ring, and FDDI modules to provide connectivity between hubs or between hubs and end stations.

The Model 3304A host module provides either manual or network management-controlled switching between the A and B channels on the multisegment backplane of the System 3000 hub. For backplane switching to occur, the System 3000 hub must be equipped with both a dual-channel network mamagement module and a multisegment Ethernet backplane.

Redundant fiber links can be created by setting hardware jumpers on the Model 3304A host module. In this configuration, the primary port in the pair is active while the second port remains in standby mode unless a fault occurs. Redundant links can also be created with all System 5000 fiber Ethernet ports.

Eight 10BASE-F figer-optic ports with metal ST-type bayonet connectors.
Supports redundant links and offers remote link fault signaling.
Adjunct port pair hardware redundancy for ports 1-2, 3-4, 5-6, 7-8, controlled by four independent hardware jumpers.
IEEE 802.3 10BASE-FL signaling (fully interoperable with FOIRL).
Modular design simplifies installation of various Ethernet cabling systems.
Supports cabling distances of up to 2 kilometers.
Network management interface.

Model 3307 and 3307HD Ethernet Host Module

The Model 3307 and the Model 3307HD Ethernet Host Modules support host connections to 10BASE-T transceivers or interface cards. These modules are designed to fit into System 3000 hubs and can be combined with other Ethernet, token ring, and FDDI modules. With System 3000 Ethernet retiming or network management modules, they offer solutions for running 10 Mbps Ethernet over unshielded twisted-pair cable.

· The Model 3307 host module incorporates a 50-pin Telco D connector as the physical interface to the network to support up to 12 host connections.

· The Model 3307HD host module offers two 50-pin Telco D connectors for a total of 24 host connections.

Both host modules provide either manual or network management-controlled switching between the A and B channels on the multisegment backplane of the System 3000 hub. For backplane switching to occur, the System 3000 hub must be equipped with both a dual-channel network management module and a multisegment Ethernet backplane.

Support for 12 Ethernet host connections (Model 3307 host module) or up to 24 Ethernet host connections (Model 3307HD host module) in a single slot.
Fully integrated with Bay Networks network management systems.

Model 3308B Ethernet Host Module

The Model 3308B Ethernet Host Module provides Ethernet connectivity over unshielded twisted-pair cable. The module provides 12 10BASE-T ports with modular RJ-45 connectors.

The Model 3308B host module provides either manual or network management-controlled switching between the A and B channels on the multisegment backplane of a System 3000 hub. For backplane switching to occur, the System 3000 hub must be equipped with both a dual-channel network mamagement module and a multisegment Ethernet backplane.

12 10 BASE-T ports with modular RJ-45 connectors.
Per-port link integrity test function.
Per-port automatic polarity detection and correction.
Integrated with Bay Networks network mamagement.

Model 3333 and 3334-ST Ethernet Retiming Module

Working with System 3000 host modules, the Model 3333 and Model 3334-ST Ethernet Retiming Modules provide the required IEEE 802.3 repeater function.

· The Model 3333 module provides an AUI port for maximum flexibility for connection to other hubs or network equipment.

· The Model 3334-ST module provides a fiber-optic port with FOIRL-compatible signaling.

Not required if the network management module is on the segment.
Use with host modules in a System 3000 hub.

LattisSecure Ethernet Host Module

The Model 3368 LattisSecure Ethernet Host Module, which is physically identical to the Model 3308B, provides host units with a level of network security not ordinarily available with Ethernet. Model 3368 modules are designed to work with Bay Networks DOS and Unix-based network management systems and Model 3313A, 3314A, 3315A, and 3314S network management modules to protect against eavesdropping and other forms of unauthorized network access.

For mission-critical network operations where security is a necessity.
Makes sensitive data inaccessible to internal hackers or competitors.
Alerts network managers to unauthorized users or configuration changes.

Model 3328 Ethernet Switching Engine

The Model 3328 Ethernet Switching Engine (ESE) provides much of the functionality of a true bridge at a lower cost. The ESE allows multiple parallel data exchanges to take place simultaneously with minimal latency. The ESE is a 6-port module that fills a single slot in a System 3000 hub.

Use to build high-performance Ethernet departmental networks capable of supporting all segments at full bandwidth.
