   2. Introduction This document provides an introduction on how to setup or change login credentials for the user management of the CMES. 2.1. Default settings The MNS Digital Edge is provided from ABB with the custom specific project installed. Within project specification the customer defines the number of users which have access to CMES and the respective user roles. In this case ABB will set-up the CMES with the agreed user accounts. After delivery it’s mandatory to change at least the user passwords. In case the users and roles are not defined from project, 2 default users are installed: Administrator and Operator. This is also valid when the MNS Digital Edge is ordered as spare part. Default login credentials are: Administrator User name: EdgeGwAdmin Password: PleaseChangeMe Operator User name: EdgeGwUser Password: PleaseChangeMe For cyber security reason, it’s mandatory to change the password after installation of the MNS Digital Edge. ABB will take no liability caused by using the default passwords. Please contact your IT department about details of password management and cyber security measures in your company. A process for regular update of anti-virus software needs to be implemented. By default, the Windows Defender is installed and activated. Please ensure to update the Windows OS and the anti-virus software on regular basis.

   3. Configuring the User Management for the CMES This chapter explains possible adaptions of the user management for users of the pre-installed MNS Digital Edge: • Create a new user • Adding a new user • Changing users • Changing passwords by Windows remote desktop application. 3.1. Creating a New User for CMES To create a new user, you have to login as administrator. The following steps are describing the workflow how to create a new user with the role “operator”. An operator has the permissions to acknowledge alarms. It is also described how to give a user the role “Read Only” at the crucial steps. This user has no permission to acknowledge alarms. Step Actions Remark 1 • Login by remote desktop1 as administrator The password is provided from your ABB contact together with the MNS Digital Edge. 2 • Right click windows symbol “Computer Management”-Local Users and Groups” 1To access the windows operating system alternatively a monitor, keypad and mouse can be connected to the MNS Digital Edge

Password Complexity Rules and Password History The password has to contain characters from three of the following categories: • Uppercase letters of European languages (A through Z, with diacritic marks, Greek and Cyrillic characters) • Lowercase letters of European languages (a through z, sharp-s, with diacritic marks, Greek and Cyrillic characters) • Base 10 digits (0 through 9) • Non-alphanumeric characters (special characters): (~!@#$%^&*_-+=`|(){}[]:;"'<>,.?/) Currency symbols such as the Euro or British Pound are not counted as special characters for this policy setting. • Any Unicode character that is categorized as an alphabetic character but is not uppercase or lowercase. This includes Unicode characters from Asian languages A new password is only accepted by Windows when it is differs from four previous passwords.

Since the MNS Digital Edge is connected to an Ethernet network it is customer’s sole responsibility to provide and continuously ensure a secure connection between the MNS Digital Edge and customer network or any other network (as the case may be). The MNS Digital Edge has following service ports open on the integrated Ethernet interfaces: Port Service Purpose 443 https / wss WEB user-interface of ABB Ability™ Condition Monitoring for electrical systems - CMES 3389 RDP Windows remote login, e.g. used for the above described user password management Customer shall establish and maintain appropriate measures (such as but not limited to the installation of firewalls, application of authentication measures, encryption of data, installation of antivirus programs, etc.) to protect the MNS Digital Edge including CMES, the network, its system and interfaces against any kind of security breaches, unauthorized access, interference, intrusion, leakage and/or theft of data or information. ABB Ltd. and its affiliates are not liable for damages and/or losses related to such security breaches, unauthorized access, interference, intrusion, leakage and/or theft of data or information.
