3.3 Connecting a Powered Device to the
Switch Using Power over Ethernet (PoE)

Using a CAT5 cable, connect the powered device (PD)
to any of the eight ports on the switch. The switch will
detect the PD and supply 48-V power to the device
over the CAT5 cable.

NOTE: The PD must comply with the IEEE 802.3at/af

standard.

2. Overview

2.1 Introduction

This switch provides eight 10-/100-/1000-Mbps 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.

The switch installs where space is limited and provides
smooth network migration and easy upgrade to
network capacity. It can be rackmounted in a 19”
cabinet or rack.
