Introduction
The 3Com® SuperStack® 3 Switch 3848
is ideal for Gigabit to the desktop applications
in high performance workgroups. As the basis
for a future-proof Enterprise workgroup environment,
with compatibility with slower desktop connections,
it can be the platform to support a gradual
move to Gigabit speeds.
Forty-eight
auto-sensing 10/100/1000 copper ports provide
flexible wirespeed desktop and workgroup attachments,
which can ease migration for environments
with a mix of 10/100 and Gigabit-enabled desktops
and servers. Four dual-purpose slots support
SFPs that can connect to fiber cabling for
flexible Gigabit Ethernet backbone and server
connections.
Resiliency
features such as IEEE 802.1w Rapid Spanning
Tree Protocol and IEEE 802.3ad link aggregation
(LACP) help ensure uptime and availability.
Enterprise-class
security features include IEEE 802.1X network
login, SSH/SSL encrypted device log-in, and
access control lists.
For
a scalable, stackable, future-proof Gigabit
switching solution incorporating all of the
above features, the SuperStack 3 Switch 3870
48-Port is recommended.
