6.4.2
Network operation
The PC is connected to a company network LAN. The REA VeriCube is connected from
the "Data/IN" connection with an available and connected (patched) network socket.
The server (DHCP) in the network automatically assigns the network addresses.
When the company network is subjected to heavy network traffic, disruptions (the
device shows network errors) may occur during operation. When these disruptions
become too frequent, the network must be isolated by the network administrator or
alternatively the REA VeriCube needs to be connected to the computer with a
separate network connection (see the previous section).
6.4.3
PoE in switch
Operation using an Ethernet switch, which supplies PoE power (instead of using the
supplied PoE power supply) is possible. A connection, which can provide 30W power,
is required. This mode of operation is the responsibility of the User and cannot be
certified by the manufacturer. The PoE power supply is an industry standard and is,
therefore, usually non-critical as long as a PoE switch is correctly specified and is not
overloaded by too many devices.
6.4.4
MAC addresses
Every network-enabled device receives a MAC address from the manufacturer. The
MAC address is provided on the type label. Some network environments are
configured in such a way that only known devices are allowable. In this case, please
inform your IT department of the unit’s MAC address.
6.4.5
Firewall and network type
When a firewall is active, it must be configured in such a way that the network
operation between the PC and the REA VeriCube can pass safely through the firewall.
During initial installation, the security rules are usually required.
When the operating system recognizes a new network, it is asked whether this is a
public network. This must be answered “NO” because Public networks are WLAN (at a
railway station, airport, etc.) and not applicable for this device.
When there are particularly strict security rules in a company or if the network is
heavily loaded with data traffic, REA recommends using a second Ethernet port on
the PC which is dedicated to the REA VeriCube.
Supplied with the delivered unit, there is a document which describes the network
integration in detail and also designates port details.
In difficult installations, please refer to this document.
