How do I install the network card into my computer?

Turn off your computer, unplug it, and open the case. Insert the LPJ001A-T into an available PCI Express slot, secure it with the screw, and close the case. Power on and install drivers from the CD or download.

Does the LPJ001A-T support Gigabit Ethernet speeds?

Yes, the card supports 10/100/1000 Mbps auto-negotiation, allowing full Gigabit Ethernet performance with compatible routers and switches.

What is the purpose of the low-profile bracket included?

The low-profile bracket is for installation in small form-factor desktops or cases with limited height. Replace the standard bracket if needed.

How can I troubleshoot if the network card is not recognized?

Ensure the card is properly seated in the PCIe slot. Check that the LED indicators are lit. Try a different PCIe slot. Update drivers or disable secure boot in BIOS if necessary.

Is the LPJ001A-T compatible with Wake-on-LAN?

Yes, Wake-on-LAN is supported. Enable it in the device driver properties and configure your router to send magic packets.

Can I use this card for network boot (PXE)?

Yes, the card supports PXE (Preboot Execution Environment). Enable it in BIOS/boot order and configure the card's PXE ROM settings.

What cables do I need for the connection?

A standard Cat5e or Cat6 Ethernet cable with RJ-45 connectors is required. For Gigabit performance, use Cat5e or better.

How do I clean the network card?

Power off the computer and use compressed air to remove dust from the card. Avoid touching the gold contacts. Do not use liquids.

Where can I find the latest drivers for the LPJ001A-T?

Drivers are available on the Black Box support website under the LPJ001A-T product page. Alternatively, use the included CD or contact support.

2. Overview

The LPJ001A-T is a high-powered Gigabit power injector that conforms to the IEEE 802.3at power standard. As defined in 2009, this standard allows for a minimum of 25 W of power to operate with PoE equipment over a single Ethernet cable.

Use the LPJ001A-T with IP telephones, wireless access points, IP print servers, IP cameras, and Bluetooth access points.

3. Setting Up Your Power Injector

NOTE: Use CAT5e or higher Ethernet cables (not included).

1. Using screws, affix the metal feet on the front and/or rear to a flat surface such as a table or wall. See Figure 1.

NOTE: The power injector should not use the weight of the Ethernet cables for support.

LED State Function Description

ON, PoE PLUS, CONNECT LEDs	All three LEDS light part of the self-test for the internal microprocessor software.
ON LED	Lights green after two seconds	DC output voltage available	After two seconds, the ON LED will light green, indicating that the DC output voltage is available for powering an 802.3at
PoE compliant load.
CONNECT LED	Lights green is attached	802.3at load to the output RJ-45 connector.	This green LED lights when a compliant load is attached
	Blinking	802.3at load is not attached	If the load does not comply with 802.3at PoE standards, then the LEDs will blink a code indicating that the load was not detected. See Table 2 for code descriptions.
PoE PLUS LED load detected	Lights green will light.	Class 4 PD	If the load is classified as Class 4 PD, the PoE PLUS LED
as Class 4 PD	Off will stay off.	Load not classified	If the load is not classified as Class 4 PD, the PoE PLUS LED

Table 2. Failure detection codes.

Code	Name	Description
1	Incorrect resistive signature	The green CONNECT and red PoE PLUS LEDs blink three times.
2	Incorrect capacitive signature	The green ON LED blinks three times.
3	Incorrect V offset	The green CONNECT and green ON LEDs blink three times.
4	Unstable current measurement	The green ON LED blinks three times.
5	Low voltage sensed during detection (overload)	The green PoE PLUS LED blinks three times.

NOTE: After the LEDs blink three times, the power injector will continue to try to detect a valid load. Until the correct load is applied, the LEDs will continue to blink. If an open circuit is connected to the output RJ-45 connector, then the LEDs will not blink but the power injector will continue to try to detect a valid load.

If a fault, such as an overload or short circuit, is detected, then all three LEDs will blink five times in three seconds, and then go off as the power supply tries to re-detect a valid load. The LED will indicate what is wrong with the load with the codes listed in Table 2.
