SAFETY CAUTION
To reduce the risk of bodily injury, electrical shock, fire, and damage to the product, observe
the following precautions.
• Do not service any product except as explained in your system documentation.
• Opening or removing covers may expose you to electrical shock.
• Only a trained service technician should service components inside these compartments.
• If any of the following conditions occur, unplug the product from the electrical outlet and
replace the part or contact your trained service provider:
- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
• Do not push any objects into the openings of your system. Doing so can cause fire or
electric shock by shorting out interior components.
• Operate the product only from the type of external power source indicated on the electrical
ratings label. If you are not sure of the type of power source required, consult your service
provider or local power company.

Introduction
The KPOE-100 is a device designed as a mid-span Power over Ethernet PSE,
which is equipped with one-input and one-output RJ-45 connectors to connect
directly to an Ethernet cable. It delivers power together with the Ethernet data
lines over the Cat.5 cable to a PoE Powered Device such as a Wireless
Access Point or a media converter located at place where no commercial
outlet is available.

Inserting DC power plug first
Insert the DC cable of the power adapter to the injector DC IN jack as shown
below:
Applying AC power
The AC-DC48V power adapter used to supply the 48VDC power for the
injector can receive AC voltage within a range of +90 ~ 264VAC. It supports
the commercial power available worldwide. Use a proper AC power cable
matching the AC outlet in your area.
Note: Make sure the DC plug is properly seated in the DC jack before
applying AC power.
Connecting network cables
1. Connect IN jack to the switched port of a Fast Ethernet switch or Gigabit
Ethernet switch.
2. Connect OUT jack to the 802.3af compliant powered device via PoE over
Cat.5.
