2.6.1.1 Preparing for Site Installation

The power injector can be installed free standing, on an even horizontal surface or wall mounted
using the power injector’s wall mounting key holes. The following guidelines should be adhered to
before cabling the power injector to an Ethernet source and an AP-5131:
• Do not block or cover airflow to the power injector.
• Keep the power injector away from excessive heat, humidity, vibration and dust.
• The power injector is not a repeater, and does not amplify the Ethernet data signal. For
optimal performance, ensure the power injector is placed as close as possible to the
network data port.

2.6.1.2 Cabling the Power Injector

To install the power injector to an Ethernet data source and AP-5131:
1. Connect the power injector to an AC outlet (110VAC to 220VAC).
2. Connect an RJ-45 Ethernet cable between the network data supply (host) and the power
injector Data In connector.
3. Connect an RJ-45 Ethernet cable between the power injector Data & Power Out connector
and the Symbol AP-5131 LAN port.
CAUTION Ensure AC power is supplied to the power injector using an AC cable
with an appropriate ground connection approved for the country of
operation.
CAUTION Cabling the power injector to the AP-5131’s WAN port renders the
AP-5131 non-operational. Only use a AP-PSBIAS-1P2-AFR model
power injector with the AP-5131’s LAN port.
