NIAGARA 2818 10 Gbps dual segments External Bypass Switch
Modular External Active Bypass for Gigabit Ethernet

Niagara 2818 is a dual segment 10 Gigabit Intelligent Active Bypass Switch with redundant failover capabilities. The active bypass enables plug and play connectivity, includes an auto heartbeat and does not require additional drivers to be installed on connected appliances. The unit possesses management functionality that can be utilized via an extensive web GUI or CLI which enables flexibility and multiple configurations.
The Niagara 2818 passive bypass feature automatically switches the network traffic upon power failure of an attached in-line device, preserving network connectivity. The Niagara 2818 is designed to integrate with UTM, Firewall, WAN Acceleration, QoS, IPS, IDS and IT security appliances.

When Niagara 2818 detects an appliance malfunction such as a software crash, system failure or loss of power, the in-line traffic continues to flow through the network link, but is no longer routed through the in-line device. This ensures that network devices can be removed and replaced without network downtime. Once the system is back up or the power is restored to the appliance, network traffic is seamlessly diverted back to the in-line device, allowing it to resume its critical functions. Alternatively, if an appliance connected to the primary segment fails and a secondary appliance is available, the bypass switch will pass all network traffic through the secondary appliance providing redundant fail-over with minimal packet-loss until the primary appliance is restored.

Essential Features

Niagara 2818 provides major features that are essential in today’s data centers:

• Active switching of traffic in case of system failure
• Passive Bypass which is essential during power loss
• High availability failover capabilities
• 10 Gigabit Multi (SR) and Single (LR) mode support
• Redundant power supplies for maximum reliability
• Dedicated Management Port and Console Port
• Extensive CLI and WEB based management
• SSH and HTTPS for secure Management
• TACACS+ authentication
• Syslog support
• RoHS Compliant
• EMC, FCC Class A, UL (Safety) Certifications

Extensive Bypass Configuration

Niagara 2818 allows for multiple bypass configurations including:

• Bypass - fail open or fail close
• Bypass heartbeat custom configurations including:
  • Heartbeat pattern
  • Heartbeat frequency
• Bypass on link loss
• Configuration of the number of link losses prior to activating bypass
• Configuration of the number of heartbeats prior to disabling bypass

Highly Reliable

Niagara 2818 utilizes two redundant external power supplies for maximum reliability.

Niagara 2818 deploys passive bypass along with active switching for fail safe operation.

Management Software

Niagara 2818 management supports:

• Web based management via a secure https:// connection
• Extensive CLI interface
• SSH connectivity over the management port
• SNMP traps on defined events
• E-mail notification on defined events

These capabilities provide a simple, secure and easy way to maintain, monitor and manage the appliance and the network.
