Cisco Catalyst 3750 Series
Hardware Features continued
Cisco StackWise Technology
A unique stacking architecture optimized for
Gigabit Ethernet, this technology is designed
to respond to additions, deletions, and
redeployment while maintaining constant
performance. It unites up to nine individual
Cisco Catalyst 3750 switches into a single
logical unit, using special interconnect
cables and stacking software. The stack is
managed as a single switching unit controlled
by a master switch elected from one of
the member switches. The master switch
automatically creates and updates all the
switching and routing tables. A working stack
can accept new members or delete old
members without service interruption.
Addition of IP Communications
Cisco Catalyst 3750 Series PoE models
support Cisco IP phones and Cisco Aironet®
wireless LAN (WLAN) access points, as
well as any IEEE 802.3af–compliant end
device. The Catalyst 3750 24-port models
can support 24 simultaneous full-powered
PoE ports at 15.4 watts (W) for maximum
powered device support. The 48-port
versions can deliver the necessary power
to support 24 ports at 15.4W, 48 ports at
7.3W, or any combination in between.
