Use models with fiber ports to add long-distance fiber links—up
to 100 kilometers—to your network. Single-strand fiber models
enable you to send and receive over a single fiber strand, so you get
more use from your fiber infrastructure.
enable you to send and receive over a single fiber strand, so you get
more use from your fiber infrastructure.
One port on each switch is for high-priority VoIP, which ensures
that voice packets get through first.
A full-featured switch
PoE PD Switches provide the features you’re looking for. All copper
ports are dual-speed, autosensing 10-/100-Mbps ports. MDI/MDI-X
means you never need to worry about having a crossover cable.

Broadcast storm protection (message rate filtering) prevents net-
work downtime by shutting down ports if broadcast or multicast
traffic exceeds its threshold.
traffic exceeds its threshold.
DiffServ on all ports provides quality of service (QoS) prioritization
so crucial network traffic gets through first.
Link Loss on all fiber ports notifies you if the fiber link fails.

Use fiber ports to extend your network up to
100 kilometers (62.1 miles).

Receive power from a PoE PSE device.
»
Use copper ports to increase network port
density.

Single-strand fiber models transmit
and receive on a single fiber, enabling you to
maximize use of your fiber infrastructure.

FEATURES
PoE PD Switches are perfect for your network’s edge. Unlike most
Power over Ethernet (PoE) switches, which are power sourcing equip-
ment (PSEs) that provide power to PoE devices, these switches are
powered devices (PDs) and receive their power from a PSE. These
switches are an easy way to extend the range of your Ethernet
network and increase port density.

switches are an easy way to extend the range of your Ethernet
network and increase port density.
Powered by Ethernet
PoE PD Switches receive their power from any PoE PSE device
across CAT5 or higher UTP cable. Because they’re powered by the
same cable that provides their Ethernet connection, installation is
simplified and you don’t need to worry about having power outlets
at remote locations, saving you installation costs.

A wide range of port options
These nimble switches are available with copper ports only or with
copper ports plus a fiber uplink. There is even a model with an SFP
port that enables you to use SFPs for greater flexibility on the fiber
link. One copper port on each switch supports PoE.
