User’s Manual
FCC Warning
This device has been tested and found to
comply with limits for a Class A digital device,
pursuant to Part 15 of FCC Rules. These
limits are designed to provide reasonable
protection against harmful interference when
the equipment is operated in a commercial
environment. This equipment generates
and radiates radio frequency energy and, if
not installed and used in accordance with the
user’s manual, it may cause interference in
which case users will be required to correct
interference at their own expenses.
CE Warning
This is a Class A product. In a domestic
environment, this product may cause radio
interference in which case the user may be
required to take adequate measures.
Introduction
This switch provides 24 10/100/1000M ports.
It was designed for easy installation and high
performance in an environment where traffic
is on the network and the number of users
increases continuously.
It consists of 24 PSE/PoE ports. That can
solve the limitation of the power outlet
location and offer the system designer a
flexible solution to locate the network device
everywhere.
The rack-mount size was specifically
designed for medium to large workgroups.
The Switch can be installed where space is
limited; moreover it provides smooth network
migration and easy upgrade to network
capacity. The 19” size can be rack-mount on
19” cabinet.
