Hardware Sizing

The following lists the machine specifications with no other EF components installed on the VM.

vCPU	vRAM	vDisk	Notes
2 cores (2.60GHz, 2 processors)	4 GB	1x100 GB mounted on /	In case MSSQL server is installed on a separate machine
4 cores (2.60 GHz, 4 processors	8 GB	1x100 GB mounted on /	If MSSQL server is installed on the same machine as the wallboard stack

For HA, the same specifications would be doubled for two machines.

To get machine specifications for a larger agent volume and/or with other ExpertFlow products in a co-resident deployment, please get a quote from ExpertFlow or contact your ExpertFlow Account Manager.

Software Requirements

Wallboard Reporting/ Display Device

The provisioning of reporting devices is partner/customer's responsibility. For reporting device, one of the following hardware solutions must be provided to display wallboard views in the production environment.

An existing PC with a pre-installed OS, Monitor or LCD for wallboard display OR
A Smart LCD with an embedded browser to open the wallboard view OR
A raspberry pi device with OS installed with an LCD to display.
For raspberry pi device's details, see https://www.raspberrypi.org/products/raspberry-pi-3-model-b/

Port Utilization

The following ports should remain open on the Firewall. The local security policy and any antivirus should also allow open communication on the following ports.

Type	Source Host	Source Port	Destination Host	Destination Port
HTTP	Enterprise web user	any	Dashboard & Wallboards	80
HTTPS	Dashboards & Wallboards server	any	Dashboard & Wallboards	443
UDP/TCP	Dashboards & Wallboards server	any	MS SQL Server (CCE DB)	1433

System Access Requirements

Deployment Privileges

Administrative privileges (root) on the machine are required to follow the deployment steps. The Internet should be available on the machine where the application is being installed and connections on port 9242 should be allowed in the network firewall to carry out the installation steps.

Provision Database and a user on SQL Server Cluster

The following database and the privileged SQL user is required to connect to the application database. The application will create its tables and other schema objects itself after connection.

Create a wallboard application database with the name EFWallboard.
Create an SQL Server User EFUser with a database role db_owner on the EFWallboard database.

Integration with UCCX

To read CSQs and agents list from CCX, we need admin user credentials to access UCCX Configuration APIs to fetch the list of CSQs, agents, and teams.

To access the Cisco CCX database remotely via the wallboard application, CCX reporting user (uccxhruser) password is required.

Integration with UCCE

Since we need access on the Cisco AW database remotely, create an SQL server user, EFUser, with db_datareader role on the Cisco AW database.

Time Synchronization Requirements

If the system dates and times are not synchronized, the system can produce unpredictable results. Therefore, the EF applications and Cisco Contact Center should have their time zone and date/time properly configured, according to the geographic region and must be synchronized.

To configure the time zone, please see the instructions from the hardware or software manufacturer of the NTP server. The application servers should be synchronized. This synchronization should be maintained continuously and validated on a regular basis. For security reasons, the Network Time Protocol (NTP) V 4.1+ is recommended.
