Combining high port density with low per-port pricing for a cost-effective switching solution,
the BayStack 425 Switches are designed for small to medium-sized businesses and branch
offices that consider price to be a predominant decision factor when acquiring advanced
networking functionality such as:
• High-density, cost-effective stackable switching
• Flexible combo uplink port options
• Easy set-up
The BayStack 425 Switches are available in two models—the BayStack 425-24T Switch
(Figure 1) and the BayStack 425-48T Switch (Figure 2).
The BayStack 425-24T Switch has 24 10BASE-T/100BASE-TX autosensing ports, 2 flexible
combo uplink ports, and built-in stacking ports. It can be used standalone or in a stack of up
to 8 switches that can be easily managed as a single unit, to get up to 192 10/100 Mbps ports.
The BayStack 425-48T can also be used standalone or in a stack of up to 8 switches for up to
384 10/100 Mbps ports based on a future software release. Advanced features such as
Distributed Multi-Link Trunking, IGMP Snooping, VLAN Trunking, and flexible manage-
ment tools help efficiently manage the network traffic. BayStack 425 Switches are ideal stack-
able switching solutions for small and medium businesses needing performance and scalability
at cost-effective prices (Figure 3).

Features and benefits

Full autosensing on every port
Every UTP port on the BayStack 425 Switches is equipped with autosensing technology to
automatically detect and support the speed and mode of a connected device. The ports deter-
mine whether a connected device is operating at 10 Mbps or 100 Mbps, and automatically
adjust to the optimal speed. Each of the switched ports can also automatically detect and
support full-duplex connections to servers, power-user end stations or other switches, as well
as half-duplex connections to legacy NICs or hubs.

High-density stacking architecture
The plug-and-play cascade stacking architec-
ture permits connection of up to 8 BayStack
425 Switches with stack cables (Figure 4) into
a single manageable unit of up to 192 10/100
Mbps ports. With the BayStack 425-48T
Switch, up to 384 10/100 Mbps ports can be
achieved in a stack of eight units. Two built-in
Gigabit stacking ports in the rear of the switch
provide easy connections to other members
of the stack; there is no need to purchase a
cascade module or use an uplink port for
stacking. This scalable architecture protects
the network investment, as business needs
change or grow, enabling a cost-effective "buy
as you grow" strategy. When a BayStack 425-
24T Switch is being stacked, one of the combo
uplink ports (port 26) is turned off. When the
stacking feature becomes available for BayStack
425-48T, combo port 50 will be turned off.
Note that the BayStack 425-48T Switch cannot
be stacked with itself or with BayStack 425-24T
and BayStack 420-24T Switches. BayStack
425-48T Switch is standalone only; it will be
