About the PD-Switch
The PD-Switch is an unmanaged Ethernet powered device (IEEE 802.3af) that allows
the port density and service area of Ethernet networks to increase. As a powered
Layer 2 device, this switch receives power over the Ethernet cable instead of using a
separate power outlet, providing Ethernet service to locations without being
constrained by the availability of power outlets. The store and forward switch
function allows the extension of Ethernet service to locations a total of 200 meters
from the Ethernet source. All RJ-45 Ports auto negotiate 10/100BaseT, full/half
duplex, and automatically configure for MDI or MDIX operation. The optional Fiber
Port is fixed at 100 Mbps full duplex.
The PD-Switch provides a variety of port configurations:
• One IEEE 802.3af PoE compatible RJ-45 port (Port 1 “PD”)
• One high-priority RJ-45 port (Port 2)
• And one of the following three configurations:
Configuration 1: Three additional RJ-45 data ports (all copper version)
Configuration 2: Two additional RJ-45 data ports and one SFP data port
Configuration 3: One additional RJ-45 data port and one Fiber-Optic data port (SFP).
Port 2 is dedicated for high priority applications. All other RJ-45 ports provide fixed
DiffServ/ToS-PRI prioritization, giving higher priority to all traffic with a VLAN TAG
with PRI>4. All RJ-45 ports incorporate the Auto Cross and Auto Negotiation
features. The Fiber-Optic configuration also includes the Far End Fault feature that
provides notification of far-end link loss on the fiber port.

Installing the PD-Switch
The PD-Switch is ready to use. Simply connect the appropriate data cables to ports 2
and up. Then connect the powered Ethernet cable to Port 1 (PD).
Wallmount Installation
The PD-Switch includes two X-shaped Wallmount holes in the enclosure. These
holes accommodate the use of screws to flushmount the PD-Switch to a wall.

Holes
DIN Rail Mounting
The PD-Switch can be mounted with two DIN Rail clips, a hardware option available
through IMC Networks. The DIN Rail clips include screws, to allow the installation
onto a DIN Rail. Install the screws into DIN Rail clips, which should be mounted
perpendicular to the DIN Rail. Snap the converter onto the clips. To remove the
converter from the DIN Rail, use a flat-head screwdriver into the slot to gently pry the
converter from the rail. The DIN rail clips can be installed either on the bottom of
the PD-Switch or on the side.
NOTE
When using the side-installed location, remove the countersunk screw from the enclosure,
and then use the vacated hole for one of the DIN clip screws.

Port LEDs
The ports on the PD-Switch include diagnostic LEDs that indicate unique information
about the port functionality and status.
PD-Switch-TX/5
For all units with 5 copper ports, the two LEDs associated with each twisted pair port
are defined as follows:

PD-Switch-TX/3+FX
On units with a 1x9 fiber port, the FDX LED of port 3 has been re-defined as the “FX-
LNK/ACT” LED for the fiber port. Note that the “LNK” LED requires a valid Link
signal and no Far-End-Fault (FEF) from the fiber line.

Applications
In the following example, PD-Switches have been connected to a central (PoE) PSE-
Switch, extending the range of the network and increasing port density.
One PD-Switch uses the standard four RJ-45 ports to connect to the network, while
the other two use the fiber and SFP configurations to extend the network beyond the
200m range.
NOTE
This product must be connected to PoE networks and is not intended for connection to
outside plant installations.

Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from
a reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.
2. Dust caps are installed at IMC Networks to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic bag or box
so that when reinstalled they do not introduce any contamination to the optics.
4. If you suspect that the optics have been contaminated, alternate between
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units, containing electronic components. Always observe the following
precautions when installing or handling these kinds of products
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
3. Hold the units by the edges; do not touch the electronic components or gold
connectors.
4. After removal, always place the boards on a grounded, static-free surface, ESD
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.
WARNING! Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
