- Description:
- Twenty-four (24) 10Base-T/100Base-TX or 100Base-FX auto-sensing ports for desktop connectivity.Flexibility of high-speed uplink options including Gigabit Interface Converter (GBIC)-based MDA (Media Dependent Adapter) for up to 70 km fiber connections to the network core.Failsafe stacking architecture of up to eight BayStack 410 and 450-series switches (and BayStack Business Policy Switch) in a self-healing, cascade configuration to provide up to 224 ports in a single managed entity.Up to 64 port-based or protocol-based 802.1Q VLANs on each switch (any port), to extend broadcast domains and segment network traffic.MultiLink Trunking (MLT) to provide bandwidth of up to 800 Mbps with automatic failover, useful for spanning multiple units of a stack.

- Management
- Remote Management Protocol: SNMP, RMONManageable Fully Integrated into Optivity Network Management Software:BayStack 450 Switches feature built-in support for Optivity network management software, enabling complete Simple Network Management Protocol (SNMP) and RMON monitoring and control. Network administrators can manage their entire network, including all hubs, switches, and routers, from a single management station, dramatically reducing the network total cost of ownership. Easy-to-Use GUI Management:BayStack 450 Switches can be configured and managed by using the Device Manager Software. Also, VLAN Manager software may be used for configuring and managing VLANs consisting of BayStack 450 and Accelar Switches. Both software can be downloaded free from the web site. BayStack 450 Switches may also be managed by using Optivity NMS and NCS software.In addition to above choices, an easy-to-use menu-driven interface can be accessed via console or Telnet for complete configuration and management for the BayStack 450 Switch. Other Advanced Management Features:Adjustable rate limits protect the LAN against broadcast or multicast storms that can severely limit performance.BootP and TFTP support allows centralized switch IP address assignment, software upgrades, and SNMP agent updates over the network.The RADIUS-based security feature uses the RADIUS (Remote Authentication Dial-In User Services) protocol to authenticate local console and TELNET logins.The Autotopology feature allows network topology mapping of other switches in the network.

Miscellaneous
- Additional Information
- Communication Mode: Half-duplex, full-duplexModular designFree Fall/Drop: ISO 4180-s, NSTA 1AVibration: IEC 68-2-6/34Shock/Bump: IEC 68-2-27-29Stackable Up to 8 Units and 224 PortsFail-Safe Cascade Stacking ArchitectureFlexible Uplink Options Fail-Safe Design Features:Redundant cascade stacking architecture.Each unit in the stack has a full copy of the stack configuration so in the unlikely event of any unit failure, operation of the stack continues without affecting application connectivity.Gigabit uplinks (for BayStack 450 Switches only) feature LinkSafe, which provides two different physical fiber connectors for each Gigabit uplink. Upon primary path failure, the traffic is diverted to the redundant path in microseconds, protecting critical Gigabit Ethernet connections to servers or the network center.MultiLink Trunking can be implemented across the stack, where connections between individual devices (for example, between a BayStack 450 Switch and an Accelar 1200 Routing Switch) can be aggregated for both higher bandwidth and redundancy. Should one port connection fail, other connections within the MultiLink Trunk assume the full traffic load seamlessly. MultiLink Trunking also allows servers and critical resources to be connected to different switches in the stack to achieve "Multi-Homing," whereby link redundancy is extended to include unit redundancy, resulting in highly available critical resources (see Figure 2).Each switch includes a Redundant Power Supply Unit connection. Should the switch's built-in power supply fail, the Nortel Networks RPSU (sold separately) will automatically supply power to the switch for uninterrupted operation.
