2.5 Safety Procedures: General Precautions
Please read the following precautions carefully before installing and connecting the system to a power source:
NOTE: Only qualified and trained service personnel (in accordance with IEC 60950 and AS/NZS 3260) should install, replace, or
service the equipment. Install the system in accordance with country or national codes, or to the U.S. National Electric
Code if you are in the United States.
1. The building facilities in which the product will be used requires a fuse or circuit breaker no larger than 15 A for 120 VAC
(U.S.A.) or 10 A, 230 VAC (international). The building facilities must protect the PoE Injector from overcurrent or short circuits.
2. Before connecting the PoE Injector to a power source (including power cord requirements), read the PoE Injector Hardware
Installation procedure in Chapter 3. This procedure, as with all procedures and instructions, can be found in the PoE Injector
User Manual. To download a copy of the manual, visit ftp.blackbox.com.
3. To prevent the PoE Injector from overheating, do not operate the product in an area that exceeds the maximum recommended
ambient temperature of 40° C. Allow at least 3 to 4 inches of clearance around all ventilation openings.
4. To support the PoE Injector weight, do not stack the chassis on any other equipment. Shelf mounted equipment requires a sta-
ble and durable surface. When installed, do not push or pull on the PoE Injector when the equipment is installed.
5. The PoE Injector consists of two rows of “Data” and “Data & Power” ports. The ports use RJ-45 data sockets. Do not connect
telephone cables into these ports. Only RJ-45 data cables may be connect to these sockets.
6. Do not work on the PoE Injector system or connect or disconnect the cables, during periods of lightning activity.
7. The AC or DC plus/socket combination must be accessible at all times, as it serves as the main disconnect device to the
product.
8. Before servicing the product, always disconnect the product from its AC and DC source.
9. Disposal of this product should abide by all appropriate national laws and regulations.

• System Reset: This is a function that allows the GUI to reset the software on the unit. (If System Reset is activated and the GUI
does not respond, “Reset GUI.”)
• Firmware Download: This feature is used to download new application/firmware codes onto the unit. Contact Black Box Tech
Support at 724-746-5500 or info@blackbox.com for the latest firmware for your PoE Gigabit Injector – POE Firmware.
NOTE: Wait a few seconds for the GUI to respond to the commands selected. DO NOT click or check any commands
simultaneously. If a command is selected more than once within two seconds, the GUI may not respond properly.
The “Save Parameters to Flash” button will save system and port parameters to flash memory, so that they can be used to retain
the firmware across reboots of the unit.
The “Restore Factory Defaults” button will reset the defaults in the firmware and clear any stored data in the flash memory, so
the device will reset automatically. After the device has successfully reset, the “System Status” will read “0.” Click “Reset GUI” if
necessary. To make the factory defaults permanent, the user must click “Save Parameters to Flash.”
In the System ID field, the firmware version is represented in a major/minor format. It also specifies the hardware version.

5.3 GUI Port Description
The Port Description panel shows 16 ports. On the 8- or 16-Port PoE Gigabit Injector models, the port numbers higher than the
system port count will be shaded gray and disabled. Each section specifies the individual port descriptions for the system.
Figure 5-5. Port Description.
To enable changes to the port configuration in this section, click the “Send Port Control” button. It will send the port information
to the unit for 16 ports. Allow the GUI 10 seconds to refresh.
Port Description: Click “Edit” to edit/change the description of the port. Click “OK” to set the description on the GUI screen. If
you click “Cancel,” the previous description will be set for that particular port. Click “Send Port Control” to send the descriptions
to the system. To make this permanent, you must click “Save Parameters to Flash.”
Enable: This check box can administratively enable or disable the selected port. If you select the “Enable/Disable All Ports” check-
box, all ports will be enabled. Initially, the checkbox is not checked, by default all ports are enabled. Click “Send Port Control” to
send the command to the system. To make this permanent, you must click “Save Parameters to Flash.”
If “Detect Legacy Signature” checkbox is selected, all ports are enabled and the firmware will try to detect legacy devices. By
default, legacy detection is disabled. The message in blue states that the “Legacy Detect is Enabled” (Figure 5-5). Click “Send
Port Control” to send the command to the system. To make this permanent, you must click “Save Parameters to Flash.”
The different colored LEDs show the status of the individual ports. A Yellow LED shows the port is detecting or ready to be con-
nected. A Red LED shows the port as Disable/Error. A Green LED shows that the port is connected to a compliant load.

Different methods of connection:
NOTE: Access control from the controller setup is disabled (allowing all access).
Connection within the same network domain. (Refer to the diagram above Building #1 in Figure B-1.) For example:
• The Ethernet PoE Gigabit Injector is connected to the network domain of 192.169.1.xxx located on the 1st floor. All computers
connected to the network domain of 192.168.1.xxx can communicate with the Ethernet PoE Gigabit Injector.
• The Ethernet PoE Gigabit Injector remains connected on the network domain of 192.168.1.xxx. Since Building #1 has a main
network server that links all three floors together, the computers on the second (192.168.2.xxx) and third (192.168.3.xxx) floors
can also communicate with the Ethernet PoE Gigabit Injector.
Connection between different network domains. (Refer to the diagram above Building #2 in Figure B-1.) For example:
• The Ethernet PoE Gigabit Injector is connected to the network domain of Building #1 (192.168.1.xxx) would like to communicate
with the Ethernet PoE Gigabit Injector from Building #1. Building #1 must configure the main network server to allow access
from an outside source, in this case Building #2. Building #1 must be able to support UDP port 161, for SNMP. Once the access
is allowed, Building #2 can communicate with the Ethernet PoE Gigabit Injector.

Appendix C: Frequently Asked Questions
Question: What happens if I forget my username and passwords for the Ethernet interface?
Answer: Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com.
Question: What is the function of the “current share” pin on the CD power connector? Are there any protocols or procedures
associated with it?
Answer: The DC solution contains 3x 500W 50V rectifier modules (1000W N+1) with custom cables available for connection
between the rectifier rack and up to four PoE Gigabit Injectors. The currently shared pin is an option that could be used
to have the power supply inside the PoE Gigabit Injector currently shared with the rectifiers. There are no protocols or
procedures associated with it other than it’s designed only to work with our rectifier system, and even then it’s not
perfect sharing because of the inrush limiting components inside the PoE Gigabit Injector located on the DC input.
Question: What type of display properties settings are required to run the Black Box SMNP v3 GUI?
