Network-level Failover Is Supported on the Following Terminal Types:
- Dispatcher Paragon Embedded Terminal for Brother
- Dispatcher Paragon Embedded Terminal for Epson
- Dispatcher Paragon Embedded Terminal for Fuji Xerox
- Dispatcher Paragon Embedded Terminal for Fuji Xerox XCP
- Dispatcher Paragon Embedded Terminal for HP
- Dispatcher Paragon Embedded Terminal for Konica Minolta
- Dispatcher Paragon Embedded Terminal for Lexmark
- Dispatcher Paragon Embedded Terminal for OKI
- Dispatcher Paragon Embedded Terminal for Ricoh
- Dispatcher Paragon Embedded Terminal for Sharp
- Dispatcher Paragon Embedded Terminal for Sharp-eSF
- Dispatcher Paragon Embedded Terminal for Sharp OSA5
- Dispatcher Paragon Embedded Terminal for Toshiba
- Dispatcher Paragon Embedded Terminal for Xerox
Prerequisites
- A third-party load balancer or Windows NLB (WNLB) must be properly configured for Terminal Failover.
- Etcd must be enabled.
Enable etcd
- Log in to the Dispatcher Paragon management interface with sufficient rights to administer printers (for example, "admin").
- Go to System > System settings
- Set enableEtcd property to enabled and save the configuration.
- Restart the Dispatcher Paragon Terminal Server service on all Management and/or Site servers.
- Reinstall Embedded terminals after this change.
When enabled, etcd will be run with Terminal Server.
Additional Configuration for OKI and Toshiba Embedded Terminals
Certificate configuration
Each MFD needs to have uploaded certificates from all Terminal Servers connected to the failover group. Before uploading certificates it is necessary to rename the files to unique ones since these MFDs are unable to store more certificates with the same file names.
IP configuration
- Set the property forceInternalLdapServerIp (expert view) to the failover/load balancer virtual IP address/hostname.
- Install or reinstall Dispatcher Paragon Embedded Terminal for each OKI and Toshiba device.
When most of the cluster members are offline for about 24 hours, there is a possibility that the user will not be able to enter the Dispatcher Paragon application. If the problem occurs, restart the Terminal Server service on all nodes or wait for an hour.
Additional Configuration for Brother and HP Embedded Terminals
For the HTTPS configuration these MFDs always check the certificate sent to them by the server they are connecting to. The checks performed are the following:
- The subject has a valid name matching the name of the page to be viewed, in this case the IP address of the machine with Terminal Server installed.
- The date is valid, certificate is not expired.
- It is issued by a trusted certification authority.
It is necessary to create a valid certificate issued for the virtual address and configure all the Terminal Servers to use it according to Configuring secured connection between terminals and Terminal Server guide. After this is set up, install or reinstall the Dispatcher Paragon Embedded Terminal on all Brother and HP MFDs in order to upload the certification authority to these devices.
