Active circuit protection
The BayStack 460 Switch can automatically disable a port if there is a short. All the other
ports on the switch will remain active and will not be affected by the disabled port.
Plug-n-play IP Telephony switching
The BayStack 460 Switch provides simplified Web-based configurations on data and power
properties. The graphical user interfaces make it simple to set up data and power configurations.
Convenience of a single cable
With the BayStack 460 Switch, data and power can be transmitted over one cable without using
a power outlet. There is no need for a separate cable connecting the device to a power outlet.
Significant space and cost savings
Traditionally, a mid-span patch panel device connects via a UTP cat 5 cable to a standard
Ethernet switch and then the mid-span patch panel device sends power over another stan-
dard UTP cat 5 cable to the device such as an IP phone needing power. In essence, two
units are needed for Power over Ethernet capability. In contrast, the BayStack 460 Switch
integrates standard LAN switch functionality with the power over UTP cable capability of
a mid-span patch panel into one unit. This results in significant cost and space savings.
BoSS (BayStack operating system Switching Software)
With BoSS, Nortel Networks becomes the first vendor to offer a single software image
that can support four different switch types: BayStack 460-24T-PWR, BayStack Business
Policy Switch, BayStack 470-48T, and BayStack 470-24T. BoSS simplifies network opera-
tions and provides the flexibility of stacking different switches in the same stack.
Simplified network operations
BoSS simplifies network operations by reducing the number of steps required for switch
software updates. With BoSS, you need to download only a single image from Nortel
Networks for four different switch types. Loading the image to different switches is also
considerably simplified. The image is loaded only to the base unit of the stack which auto-
matically loads it to other switches in the stack. Finally, keeping track of the version
numbers is much easier as only one version number needs to be remembered.
Flexible stacking with other BayStack Switches
Using BoSS, the BayStack 460 Switch is
able to stack with other BayStack switches.
BayStack 460-24T-PWR Switch can be
stacked with any combination of BayStack
470-48T, BayStack 470-24T, BayStack
Business Policy Switch, and BayStack 450.
It should be noted that the BayStack 470-48T
cannot be stacked with the BayStack 450.
Using BoSS v3.0 or higher, a maximum of
eight switches can be stacked in any valid
combination
