10/100 Autosensing
on Every Port
Every UTP port on the BayStack 350
Switches is equipped with autosense
technology to automatically detect
and support the speed and mode of
a connected device. In addition to
detecting whether a connected device
is operating at 10 Mbps or 100 Mbps,
and automatically adjusting to the
optimal speed, each switched port
also automatically detects and supports
full-duplex connections to servers,
power-user end stations or other switches,
as well as half-duplex connections to
legacy NICs or hubs.

Features and Benefits
Flexible Choices
in High-Speed Uplinks
MDAs for Gigabit Ethernet, Fast
Ethernet fiber, four additional 10/100
autosense ports, or future ATM uplinks
provide the high-bandwidth choices
that fit into any network architecture
(see Figure 1).
Redundant
Gigabit Uplink Option
The Gigabit Ethernet MDA is available
with LinkSafe,* which provides two
physical fiber connectors for the Gigabit
uplink. Upon primary path failure,
traffic is diverted to the redundant
path in microseconds, protecting
critical Gigabit Ethernet connections
to servers or the network center.
Wire-Speed Throughput
2.5 Gigabit per second (Gbps) switching
fabric and custom switching ASICs support
full 802.1D-compliant MAC Layer frame
forwarding and filtering across all ports
at the peak rate of 3 million packets per
second. The BayStack 350 Switches
continue the Nortel Networks tradition of
industry-leading throughput performance.
Advanced VLAN Support
Up to 64 port-based or policy-based
1
VLANs can be established for each
switch, to extend the broadcast domain
and segment network traffic. Each switch
can also support 4,096 transit VLANs.
802.1Q VLAN Trunking
VLAN trunking is supported on every
port of the switch, allowing efficient
means of transporting broadcast domains
across switches.
802.1p Priority Queuing
Standards-based priority queuing
enables prioritization of traffic by
protocol, so important network traffic
always get through.
