art of the successful BayStack* family, the BayStack 460-24T-PWR Power over Ethernet
Switch is a resilient, secure stackable switch with IEEE 802.3af Power over Ethernet
(PoE) capabilities to power devices such as IP phones, wireless access points, network
cameras, security and lighting devices, and access control devices (badge readers). The
switch has advanced features such as advanced Quality of Service (QoS) and high resiliency,
with the addition of Power over Ethernet capability. It enables enterprise customers to power
devices while maintaining connectivity to standard 10/100 Mbps Ethernet devices such as
PCs and servers. All 24 ports of the BayStack 460 Switch can be powered.
BoSS (BayStack operating system Switching Software) allows the BayStack 460 Switch to
stack with other BayStack switches. BoSS also simplifies software upgrades with a single
image for different BayStack switches.
High-density Power over Ethernet switch
The BayStack 460-24T-PWR Switch has 24 10/100 Mbps autosensing ports, one MDA
(Media Dependent Adapter) slot for uplink connectivity, and one cascade module slot for
stacking. Up to eight switches can be stacked to achieve up to 224 10/100 ports (using
4-port 10/100 Mbps MDA per switch) that can be easily managed as a single unit. The
2.5 Gbps cascading bandwidth offers dedicated bandwidth between switches without
sacrificing any uplink ports. The uplink ports can be used for connections to backbone
switches such as the Passport* 8600 Switch.
Full autosensing on every port
Every UTP port on the BayStack 460 Switch is equipped with autosensing technology to
automatically detect and support the speed and mode of a connected device. The ports
determine whether a connected device is operating at 10 Mbps or 100 Mbps, and auto-
matically adjust to the optimal speed. Each of the switched ports 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.
IEEE 802.3af compliant
The BayStack 460-24T-PWR Switch is IEEE 802.3af compliant. It can provide Power
over Ethernet to any IEEE 802.3af compliant device such as IP phones, wireless access
points, network cameras, security and lighting devices, and access control devices. The
benefit of being interoperable with standards-based equipment means that customers are
not forced to tie themselves to any one vendor, as the switch has the flexibility to power
multiple vendors’ devices. It can supply power up to 15.4 Watts per port, which meets the
IEEE 802.3af standard. This is more than sufficient to power most devices.
Auto discovery feature
The BayStack 460-24T-PWR Switch automatically recognizes the connection of a device
and immediately sends power to it. This automatic capability ensures fast connectivity
without manual intervention.
Dynamic power management
Each port can be configured to limit the power delivered to a device. Each port can also be
configured for power priority level—low, high, and critical. On the switch, total available
power is monitored. In the case where all available power is fully utilized, the switch may turn
off lower priority ports and turn on higher priority ports.
