Defining the A920-PC-CAB-DC-3M=

The ​​A920-PC-CAB-DC-3M=​​ is a ​​3-meter DC power cable​​ engineered for ​​Cisco Aironet 920 Series Access Points​​. Designed to deliver stable power in environments where PoE (Power over Ethernet) isn’t feasible, this cable ensures uninterrupted operation for Cisco’s high-performance wireless hardware. Its ruggedized construction and Cisco-specific connectors differentiate it from generic power cables.

Critical Technical Specifications

• ​​Voltage Compatibility​​: Supports ​​12–48V DC input​​, aligning with Cisco’s AP920 power requirements.
• ​​Shielded Design​​: Reduces electromagnetic interference (EMI) risks in industrial or densely wired settings.
• ​​Locking DC Connector​​: Features a ​​secure twist-lock mechanism​​ to prevent accidental disconnections.

Compatibility and Deployment FAQs

This cable is ​​exclusively compatible with the Cisco Aironet 920 Series​​ (e.g., AP920E, AP920I). Key user concerns include:

• ​​Q​​: Can this cable be used outdoors?
  ​​A​​: Yes—its ​​UV-resistant jacket​​ withstands outdoor exposure, but a weatherproof conduit is recommended for prolonged use.
• ​​Q​​: Does it support third-party power adapters?
  ​​A​​: While physically compatible, Cisco advises using ​​Cisco-certified power supplies​​ to avoid voltage instability.

Why Opt for the A920-PC-CAB-DC-3M= Over Generic Cables?

Third-party DC cables often lack:

• ​​Precision shielding​​, leading to signal degradation in high-interference zones.
• ​​Cisco-validated connector tolerances​​, which can cause loose connections or arcing.
  The A920-PC-CAB-DC-3M= ensures ​​consistent power delivery​​ and compliance with Cisco’s safety certifications.

Field Experience Insights

In warehouse and manufacturing deployments, ​​power stability is non-negotiable​​ for maintaining uptime in wireless networks. I’ve seen generic cables fail within months due to EMI or connector wear, while the A920-PC-CAB-DC-3M= consistently outlasts them—even in high-vibration environments. For organizations scaling their Cisco AP920 deployments, this cable isn’t just an accessory; it’s a safeguard against preventable downtime.
