Network requirements
The 3M™ SelfCheck™ System comes with an integrated network adapter and communicates with the ILS over an Ethernet network, which requires the following network infrastructure:
•The standard wired Ethernet adapter requires support for
•The optional wireless Ethernet adapter requires support for 802.11 g or 802.11 b protocols and must meet the requirements listed in the following table:
Security | Network security is the library’s responsibility. Security measures include but are not limited to the following: |
| • Separation from the library’s public wireless network. |
| • SSID transmission suppression so that the access point is not readily visible or likely to be used by |
| library patrons. |
| • Either WPA or WEP encryption, with encryption key rotation and/or MAC address filtering. |
| • If financial transactions using credit or debit cards are implemented, the library must conform to Payment |
| Card Industry (PCI) data security standards (DSS) developed by the PCI Standards Council. Requirements |
| can be found at http://www.pcisecuritystandards.org/. |
Signal Strength | The SelfCheck™ System must be located within optimal operational range of the wireless access point, as |
| determined by access point signal strength, which can be analyzed and measured using software installed |
| with the wireless network adapter. |
| • Transmitted signal strength from the wireless access point must be greater than |
| the installed location of the SelfCheck System. |
| • Software RSSI (received signal strength indicator) must show greater than 90% signal strength (all five |
| bars of RSSI are green) at the installed location of the SelfCheck System. |
Guidelines | The following can help ensure required signal strength at the SelfCheck location: |
| • Install the SelfCheck™ System within twenty feet (20 ft. [6 m]) of the wireless access point. |
| • Install the SelfCheck™ System in |
| the two. This will reduce |
