For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Optical Safety Instructions
Laser!
This symbol inform of the risk of exposure to laser beam and light emitting devices (LEDs)
from an electrical device. Eye protection per manufacturer notice shall review before
servicing.
When a connector is removed during installation, testing, or servicing, or when an energized fiber is broken, a risk of
ocular exposure to optical energy that may be potentially hazardous occurs, depending on the laser output power.
The primary hazards of exposure to laser radiation from an optical-fiber communication system are:
Damage to the eye by accidental exposure to a beam emitted by a laser source
Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber

device), if the product itself is not disconnectable
a disconnect device, if provided in or as part of the product, shall disconnect both poles simultaneously
interconnecting power circuits of different products cause no electrical hazards
A sufficient dimensioning of the power cable wires must be selected – according to the maximum electrical
specifications on the product label – as stipulated by EN62368-1 or VDE0100 or EN60204 or UL61010-1
regulations.
2.1. Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro-
circuitry.
Therefore, proper packaging and grounding techniques are necessary precautions to prevent damage. Always take
the following precautions:
1. Transport ESD sensitive parts in ESD safe containers such as boxes or bags, until they arrive at an ESD safe
workplace.
2. Always be properly grounded when touching sensitive components, or assembly.
3. Store ESD sensitive components in protective packaging or on antistatic mats.
2.2. Grounding Methods
By adhering to the guidelines below, electrostatic damage to the product may be avoided:
1. Cover workstations with approved antistatic material/mat and always wear a wrist strap connected to
workplace or heel straps.
2. Use properly grounded tools and equipment Such as field service tools that are conductive
3. Always handle ESD sensitive components by their edge or by their casing.
4. Avoid contact with pins, leads, or circuitry.
5. Switch off power and input signals before inserting and removing connectors or connecting test equipment.
6. Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam.

4.1. Faceplate Features
4.1.1. PoE Ports
When connecting the switch to a PC use a straight-through or a cross-over Ethernet cable and when connecting the
switch to an Ethernet device use UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) Ethernet cables.
The switch supports up to four 10/100/1000 Mbps Ethernet ports labeled PD PSB and PSE that are IEEE 802.3af/at,
PoE++ compatible. PD provides the switch with power using a Gigabit uplink from a PoE compatible device. If the
switch does not detect a PoE device connected to the PD port, power is not sourced and Ethernet data
communications are permitted. PSB and PSE provide a Gigabit downlink to supply further PoE compatible devices with
power, where PSB supplies 15.3 W/30 W/60 W and PSE supplies 15.3 W/30 W; after deducting the switch’s own
power consumption.
Figure 3: PoE Gigabit Ethernet Ports (3-port and 4-port)
The port variants are:
•2-port supports PD and PSB port
•3-port supports PD, PSB and PSE ports
•4-port supports PD, PSB and two PSE ports (additional PSE port on rear side)
Use CAT5e or better cable with a maximum length of 100 Meters.
