Liebert IS-WEBCARD Intellislot Web Card User Manual

Introduction

The Liebert IS-WEBCARD Intellislot Web Card is a remote management adapter designed to enhance UPS communications and control. It provides SNMP and web-management capabilities, allowing you to monitor and control your Uninterruptible Power Supply (UPS) over a network. This card integrates with various management systems, including Trellis, LIFE Services, Liebert Nform, and other third-party building and network management applications.

Key features include:

• Web interface with SNMP and Telnet capabilities.
• Provides communication interface to Trellis, LIFE Services, Liebert Nform, and third-party management applications.
• Delivers alarm notifications via email and text messaging.
• Enables monitoring of UPS parameters through a web browser.
• Compatible with Liebert monitoring software.

Setup and Installation

1. Physical Installation

1. Power Down UPS: Ensure the UPS unit is completely powered off and disconnected from the main power source before installation to prevent electrical hazards.
2. Locate Intellislot: Identify the Intellislot bay on your compatible Liebert UPS. Refer to your UPS manual for the exact location.
3. Insert IS-WEBCARD: Carefully slide the IS-WEBCARD into the Intellislot bay until it is firmly seated. Ensure the card is oriented correctly.
4. Secure Card: If applicable, use any retaining screws or clips to secure the card in place.
5. Connect Network Cable: Connect a standard Ethernet cable from your network switch or router to the Ethernet port on the IS-WEBCARD.
6. Power On UPS: Reconnect the UPS to the main power source and power it on. The IS-WEBCARD will initialize with the UPS.

2. Initial Configuration

Upon initial power-up, the IS-WEBCARD typically attempts to obtain an IP address via DHCP. If a DHCP server is not available, it may default to a static IP address (refer to Liebert documentation for default IP). You can discover the assigned IP address using network scanning tools or by connecting directly via a serial console if supported by your UPS model.

Firmware Update

It is highly recommended to update the firmware upon initial setup to ensure optimal performance and security. Older stock units may ship with outdated firmware that can cause compatibility issues or security vulnerabilities.

• Download Firmware: Obtain the latest firmware from the official Liebert support website.
• Update Method: Firmware updates often require using a TFTP (Trivial File Transfer Protocol) client. Configure a TFTP server on a computer on the same network as the IS-WEBCARD and place the firmware file in the TFTP root directory.
• Initiate Update: Access the IS-WEBCARD via Telnet or its web interface (if accessible) and follow the instructions to initiate the firmware update process, pointing to the TFTP server.
• Reboot: The card will reboot after a successful firmware update. This process can take several minutes.

Operating the IS-WEBCARD

1. Accessing the Web Interface

Open a web browser and enter the IP address of the IS-WEBCARD. You will be prompted for a username and password (refer to Liebert documentation for default credentials). The web interface allows you to:

• Monitor real-time UPS status and parameters (e.g., battery charge, load, input/output voltage).
• View event logs and alarm history.
• Configure network settings (IP address, subnet mask, gateway, DNS).
• Set up email and text message notifications for critical events.
• Manage user accounts and security settings.

Note on Browser Compatibility: Due to the age of some IS-WEBCARD firmware versions, the web interface may use older security protocols (e.g., outdated SSL/TLS versions) that modern browsers might flag as insecure or refuse to connect to. Consider using a browser with configurable security settings or accessing it from a secure, isolated management network.

2. SNMP Configuration

The IS-WEBCARD supports SNMP (Simple Network Management Protocol) for integration with network management systems. You can configure SNMP settings via the web interface or Telnet:

• Community Strings: Set read-only and read-write community strings.
• Trap Destinations: Configure IP addresses of SNMP management stations to receive trap notifications.
• MIB Support: The card supports the RFC 1628 UPS MIB, allowing standard UPS monitoring.

3. Alarm Notifications

Configure the IS-WEBCARD to send email or text message alerts for various UPS events, such as power failures, low battery, or system faults. This typically involves:

• Entering SMTP server details (IP address, port).
• Specifying sender and recipient email addresses.
• Selecting which events trigger notifications.

Security Note for Email: Older firmware versions may not support modern TLS encryption for email, potentially sending credentials or alert content in plain text. Use a dedicated, secure email relay or consider alternative notification methods if this is a concern.

Maintenance

1. Firmware Updates

Regularly check the Liebert support website for new firmware versions. Updates often include bug fixes, security patches, and new features. Always follow the manufacturer's instructions for firmware updates, which typically involve TFTP as described in the Setup section.

2. Security Best Practices

• Dedicated Management Network: Deploy the IS-WEBCARD on a private, isolated management LAN using RFC 1918 addresses to minimize exposure to external threats.
• Strong Passwords: Change default passwords immediately and use strong, unique passwords for all user accounts.
• Disable Unused Services: If Telnet or the web interface are not actively used for management, consider disabling them to reduce the attack surface. Access via RS-232 from a console server with SSH support might be a more secure alternative for configuration.
• Awareness of Protocol Limitations: Be aware that older firmware may not support modern secure protocols (e.g., HTTPS with strong TLS versions). Plan your network security accordingly.

3. Configuration Backup

Periodically back up the configuration settings of your IS-WEBCARD. This allows for quick restoration in case of a reset or replacement.

Troubleshooting

• "Unsupported Device" Message: If you encounter this message upon initial setup, it typically indicates that the IS-WEBCARD firmware is outdated and not compatible with your specific UPS model. Perform a firmware update as described in the Setup section.
• Cannot Access Web Interface:
  • Verify network connectivity to the card (ping its IP address).
  • Ensure the correct IP address is being used.
  • Check browser compatibility and security settings. Older firmware may require less restrictive browser settings or an older browser version.
  • Confirm the card has successfully booted and is operational.
• Email/Text Alerts Not Sending:
  • Verify SMTP server settings (IP, port, authentication).
  • Check network connectivity from the IS-WEBCARD to the SMTP server.
  • Ensure the email server allows connections from the IS-WEBCARD's IP address.
  • Confirm that the IS-WEBCARD firmware supports the required email security protocols (e.g., TLS).
• Card Not Responding: Power cycle the UPS (if safe to do so) to reboot the IS-WEBCARD. If the issue persists, ensure the card is properly seated in the Intellislot.
