Introducing the E3800 Switches
The HP E3800 switches are multiport switches that can be used to build high-
performance switched networks. These switches are store-and-forward
devices offering low latency for high-speed networking. The E3800 switches
also support a field-replaceable Redundant Power Supply and fan tray, Power
over Ethernet (PoE/PoE+) technologies, and full network management
capabilities.
In addition, the E3800 switches support the HP FlexChassis Mesh feature
for stacking the switches. When E3800 Stacking Modules (J9577A) are
installed in the switches, any combination of up to ten E3800 switches can be
stacked together via high-speed backplane cables to form a single extended
virtual switch. See “Stacking Information and Topologies” on page 2-23, and
the E3800 Advanced Traffic Management Guide for more stacking
information.
These switches are described in this manual:
