A separate Power Injector is required for each access point comprising the network.
Installing the Power Injector
Refer to the following sections for information on planning, installing, and validating the
installation:
• Preparing for Site Installation
• Cabling the Power Injector
Preparing for Site Installation
The Power Injector can be installed free standing, on an even horizontal surface or wall mounted
using the unit’s wall mounting key holes. The following guidelines should be adhered to before
cabling the Power Injector to an Ethernet source and access point:
• Do not block or cover airflow to the Power Injector
• Keep the unit 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 unit is placed as close as possible to the network data port.
CAUTION
To avoid problematic performance and restarts, disable POE from a wired switch port connected
to an access point if mid-span power sourcing equipment (PSE) is used between the two,
regardless of the manufacturer of the switch.
Cabling the Power Injector
To install a Power Injector to an Ethernet data source and an access point:
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.
1. Connect an RJ-45 Ethernet cable between the network data supply (host) and the Power
Injector’s Data In connector.
2. Connect an RJ-45 Ethernet cable between the Power Injector’s Data & Power Out connector
and the access point’s GE1/POE port.
CAUTION
Cabling a Power Injector to the WAN port (GE2) renders the AP non-operational. Only use a
AP-PSBIAS-1P3-AFR (or AP-PSBIAS-1P2-AFR) Power Injector with the access point’s GE1/POE
(LAN) port.
