Backed by Warranty
All BayStack 250 Series 10/100 Hubs
have a limited lifetime warranty, including
power supply. This ensures years of
worry-free operation.
Slimline 1 "U" Height
BayStack 250 Series 10/100 Autosense
Hubs are only one standard unit (1.68
inches) high, which means easy stackability
and higher port density in less rack space.
Figure 1 shows example configurations of
BayStack 250 Series 10/100 Autosense Hubs.
BayStack 250 Series 10/100
Autosense Hub Applications
All BayStack 250 Series 10/100 Autosense
Hubs support 10/100 autosensing on all
ports. This enables seamless migration
from 10 Mbps to 100 Mbps connections,
without requiring time-consuming trips
to the wiring closet whenever end stations
are upgraded to Fast Ethernet.
The BayStack 250 Series 10/100 Hubs
offer a high-performance desktop solution
for network environments that quickly
overwhelm legacy 10 Mbps solutions.
The hubs also represent an important
part of the Nortel Networks 100BASE-TX
evolution strategy, extending the power
and adaptability of the BayStack 350
Switches by filling a critical need in
evolving networks.
Installed with the BayStack 350 or
BayStack 450 10/100/1000 Switches,
the BayStack 250 Series 10/100 Autosense
Hubs play a key role in the evolution to
Fast Ethernet, providing a cost-effective
way to improve network response times.
Linking a 10/100 hub or stack to a
BayStack 350 or BayStack 450 Switch
provides the power workgroup with a
100 Mbps connection to centralized
resources such as high-utilization servers
and routers. The BayStack 250 Series
10/100 Hubs can also be linked to
100BASE-TX router interfaces on Nortel
Networks routers to create large-diameter
Fast Ethernet networks. The BayStack 253
Hub and the BayStack 255 Hub with the
100BASE-FX MDA provides a full-duplex
fiber connection to the network center up
to two kilometers.
