# Scanner

Each scanner defines a patch zone. A patch zone consists of monitored work area outlets and the respective patches. A single server manages any number of patch zones. The scanner defines the number of channels per patch zone. RJ45 cords provide connectivity between the scanner and the patch panels. TCP/IP over a standard Ethernet network provides communications between the scanners and the server.

A scanner communicates with the server. The scanner records physical layer changes even if the server is off-line. The scanner then sends the queued information when the server comes back online. The scanner does not collect data without power. All scanner configurations remain intact through power cycling. The scanner automatically begins collecting all patch and work area outlet changes after power-up.

The front of the scanner is very simple.

- Consumes less than 15 Watts
- Operates at either 110VAC or 220VAC
- Occupies 1U of rack space

Front View 1 - Status LEDs S1 and S2 - indicate present scanning mode (patch cord or scanner port) S3 through S6 - Scanner lights S3 through S6 show operation status of the scanner’s internal sub-systems. All lights are “on” for operational scanners.
2- Push buttons
On - Turns scanning function on or off. (Note: The scanner remains powered when scanning function is disabled. The scanning function is always on after power reset)
Rst - The reset button performs a warm boot of the scanner.
3 - Scanner to server connectivity
Communication between the scanner and the application running on the server occurs over standard network protocols (Ethernet and TCP/IP). There are two network ports on the front of the scanner. The network ports provide for LAN connections between the scanner and the network.

- DHCP and day-to-day operation use the LAN1 port
- Access to the scanner interface, without an operational IP network, uses the LAN2 port
- The default LAN2 IP address is “192.168.10.117”. This parameter is not user settable.

4 - Com - Factory test port

5 - Scanner to panel connectivity

- The scanner provides power and communications between the panels and scanner.
- Patch panel to scanner connections use any Cat5e (or better) RJ45 cable
- The scanner communication bus is not based on Ethernet
