changing businesses
• Provides advanced traffic management and high
levels of resilience making it ideal for rapidly
growing networks in demanding environments
Key Points
• Resilience: The BayStack 450 are designed
with a fail-safe cascade stacking architecture.
Each switch unit has a full copy of the stack’s
configuration so that, if one unit should fail,
application connectivity is not affected.
Each Gigabit uplink on the BayStack 450 is
equipped with two different physical fibre
connectors so that if one should fail, traffic can be
immediately switched to the other. MultiLink
Trunking allows ports to be aggregated for higher
bandwidth and redundancy. If one port fails, the
others take the load seamlessly. Load balancing
and fail-over protection safeguard important
connections to servers and other switches.
• Scalability: Up to 8 BayStack 450s can be stacked
to achieve 224 ports. The 410 and 450 can be
stacked together for greater flexibility.
• Performance: Hardware switching allows the
BayStack 450 to achieve a peak throughput of
3 million packets per second. Ports can be
aggregated to provide a high-bandwidth link of
800Mbps capacity (10/100 ports or 100BASE-FX
ports) or 8 Gbps (Gigabit uplink ports on the 450).
Standards-based priority queuing enables
delay-sensitive traffic such as voice or video, to
be prioritised.
• Simple network set-up: All ports automatically
detect and support the speed and mode of the
connected device.
