Flexibility - SwitchBlade
The AT-SB4008 and AT-SB4004 offer a comprehensive
set of line cards for complex networks.
Key Features
•
Hot swappable
•
Can be used in both AT-SB4108 and
AT-SB4104 chassis
•
LEDs identify port activity
•
ASIC switching
Interface options to cover a variety of
network needs.
A diverse range of interface options - including
copper and fibre, short and long haul, (SFPs, and
XFPs) - delivers network managers the flexibility
and freedom needed to tame today's fast-paced
yet price-conscious network environments.
Combining speed and reliability for the
network core.
Capable of wire-speed non-blocking switching, and
hot swappable to minimize downtime,
SwitchBlade
