Network management card APC AP9643 — internal wireless card, IEEE 802.1x, black

The APC AP9643 is an internal wireless network management card for compatible APC SmartSlot UPS devices. It provides wireless connectivity and supports IEEE 802.1x for secure authentication, enabling remote monitoring and control of power and environment-related parameters. The card is black, lightweight (approx. 0.14 kg) and integrates with APC management systems and common building management protocols for centralized oversight.

Advantages

The AP9643 offers encrypted communication options including HTTPS/SSL and SSH (up to 2048-bit), SNMPv3 support and IPv6 capability for modern networks. It supports multiple management protocols such as Modbus TCP, Modbus RS-485 and BACnet/IP for integration with building management and third-party systems. Firmware can be updated remotely via the web interface and the card supports simultaneous multi-user access and role-based accounts for controlled administration.

Suitable for

• Data centers and server rooms requiring remote UPS monitoring and management
• IT cabinets and network closets where wireless access to UPS status is preferred
• Facilities using building management systems that require BACnet/IP or Modbus integration
• Sites needing secure authentication via IEEE 802.1x and SNMPv3 for device access

When it may not be suitable

This internal wireless card requires a SmartSlot-enabled APC UPS; it is not a standalone network appliance and will not function independently of a compatible UPS. Environments that prohibit wireless devices for policy or security reasons may need a wired network management card instead.

Key specifications

• Connectivity technology: Wireless
• Networking standards: IEEE 802.1x

• Compatibility: SmartSlot-enabled APC UPSs
• Physical colour: Black; Weight: approx. 0.14 kg

How to use

Install the AP9643 into the SmartSlot of a compatible APC UPS following the UPS installation guide. Access the card’s web browser interface using the device IP address to configure network settings, IEEE 802.1x authentication, SNMP or Modbus integration, and user accounts. Use the web interface or CLI (Telnet/SSH) to monitor UPS status, schedule shutdowns or firmware updates, and connect the card to StruxureWare or other management systems as required.

What to consider before purchase

• Ensure your APC UPS model supports SmartSlot expansion and is listed as compatible with this card
• Verify whether wireless connectivity is allowed and suitable within your site’s security policy
• Confirm required protocol support (BACnet/IP, Modbus, SNMP) for integration with your monitoring systems
• Plan for IEEE 802.1x and Radius server configuration if using secure network authentication

Recommendations

For secure, reliable operation configure strong passwords, enable SNMPv3 or HTTPS, and, when available, use Radius for centralized authentication. Keep firmware up to date via the web interface and integrate event logging with your enterprise or building management system to enable timely responses to UPS events.
