Description
APC UPS Network Management Card 3 with Environmental Monitoring — AP9641
Full APC Specification: Device monitoring and management, Network Management Cards, NMC3 with Environmental Monitoring, secure remote UPS monitoring and management
The AP9641 builds on the base AP9640 NMC3 with two additional capabilities: a dedicated environmental sensor port and a USB port for firmware updates from a USB drive. For deployments where rack-level temperature and humidity matter — most production data center and network closet environments — the AP9641 eliminates the need for a separate environmental monitoring device.
Why Environmental Monitoring at the UPS
UPS units sit in the rack alongside the equipment they protect. Adding an environmental sensor directly to the UPS Network Management Card consolidates power and environmental visibility into a single device and a single management interface — without deploying separate NetBotz hardware or a dedicated environmental gateway.
Key Features
- Environmental Sensor Port: Direct RJ-45 connection for APC AP9335TH (temperature + humidity) or AP9335T (temperature only) sensors.
- USB Firmware Update: Update UPS and NMC firmware from a USB drive — useful for air-gapped or low-bandwidth deployments.
- Full NMC3 Management Suite: SNMPv1/v2c/v3, HTTPS, SSH, SCP, BACnet, Modbus, Syslog, RADIUS, EAPoL.
- IPv6 Ready: Dual-stack IPv4/IPv6 operation.
- PowerChute Network Shutdown Included: Coordinated shutdown of physical servers, virtual machines, and HCI clusters.
- 12-Month Secure NMC Subscription: Firmware updates and security patches included for the first year.

Ideal Applications
- Data Center Rack-Level Environmental Monitoring: Combined power and environmental visibility in a single device installed in the existing UPS.
- Network Closets Without Active Cooling: Early-warning temperature monitoring where overheating is a recurring concern.
- Healthcare and Lab Equipment Rooms: Temperature and humidity tracking for compliance reporting (JCI, CAP, CLIA).
- Remote and Edge Sites: USB firmware update support useful for sites with intermittent connectivity.
- Compliance-Regulated Environments: Audit-grade environmental telemetry logged alongside power events.
Questyme: NMC3 + Sensor Bundle Configurations
For most production deployments, Questyme recommends pairing the AP9641 with an APC AP9335TH temperature/humidity sensor as a bundled order — single shipment, pre-tested compatibility. Contact our team to scope your environmental monitoring deployment.
