Core Functionality of DBS-110-3PC-AU-K9=
The DBS-110-3PC-AU-K9= is a Cisco hardware component, likely part of a modular switch or router system. While Cisco’s official documentation does not explicitly reference this part number, its alphanumeric structure suggests it could be a high-density port adapter, power supply unit, or region-specific configuration module (denoted by “AU” for Australia). Such components are critical for ensuring redundancy, power efficiency, or localized compliance in enterprise networks.
Key Technical Features and Performance Metrics
Based on Cisco’s naming conventions and analogous products like the C9K-PWR-1100W= power supply, the DBS-110-3PC-AU-K9= is engineered for:
- Power Output: 1100W capacity with 3-phase AC input (3PC) for stable energy delivery.
- Redundancy: Hot-swappable design to prevent downtime during failures.
- Regional Compliance: AU certification for use in Australian electrical grids.
- Thermal Efficiency: Optimized airflow for use in Catalyst 9500 or Nexus 9300/9500 chassis.
A common user question is: “Does this unit support global voltage ranges?” While “AU” suggests regional specificity, Cisco power systems often accept 100–240V AC input, but local certifications (e.g., RCM for Australia) are mandatory.
Typical Deployment Scenarios
The DBS-110-3PC-AU-K9= is suited for:
- High-Availability Data Centers: Paired with dual supervisors for N+1 redundancy.
- Enterprise Edge Networks: Powering PoE++ switches supporting IoT devices or Wi-Fi 6 access points.
- Multi-Tenant Environments: Complying with regional electrical standards to avoid legal liabilities.
Users often ask: “Can this unit support PoE loads?” While not a PoE injector itself, it likely powers chassis that manage PoE budgets. For example, a Catalyst 9400 with 48x PoE+ ports would require ~1500W total, making dual DBS-110-3PC-AU-K9= units a viable solution.
Comparison with Similar Cisco Power Modules
To clarify confusion around Cisco power supplies, here’s a simplified comparison:
| Feature | DBS-110-3PC-AU-K9= | C9K-PWR-1100W= |
|---|---|---|
| Power Capacity | 1100W | 1100W |
| Regional Compliance | AU (Australia) | Universal (No region lock) |
| Input Type | 3-Phase AC | Single/3-Phase AC |
| Redundancy Support | Yes | Yes |
The DBS-110-3PC-AU-K9= stands out for regional regulatory adherence but may lack flexibility in non-AU deployments.
Compatibility and Integration Challenges
A critical user concern is: “Is the DBS-110-3PC-AU-K9= compatible with my Cisco chassis?” Key factors include:
- Chassis Model: Likely designed for Catalyst 9400/9500 or Nexus 9300/9500 series.
- IOS-XE Version: Ensure compatibility with 16.12.1 or later for advanced power management.
- Power Stacking: Verify if mixed PSU types (AC/DC) are allowed in the same chassis.
Misconfiguration risks include breaker tripping under 3-phase load imbalances or thermal shutdowns if airflow is obstructed. Always consult Cisco’s Power Calculator Tool before deployment.
Sourcing the DBS-110-3PC-AU-K9= Legally and Cost-Effectively
Given Cisco’s evolving product lifecycle, sourcing this unit new may be challenging. Trusted suppliers like itmall.sale offer refurbished or NOS (New Old Stock) units with:
- Compliance Guarantees: Validated AU certification and safety testing.
- Cost Savings: Up to 60% lower than list price for end-of-life hardware.
- Lead Time Optimization: Pre-configured units shipped within 3–5 business days.
Avoid gray-market sellers, as counterfeit PSUs risk equipment damage and void warranties.
Strategic Insights for Optimal Use
In my experience, region-specific hardware like the DBS-110-3PC-AU-K9= is both a blessing and a curse. While it ensures compliance, it complicates global deployments. For Australian enterprises, this unit is a no-brainer for avoiding fines. However, multinationals with AU branches should weigh the logistics of maintaining regional spares versus adopting universal PSUs.
One overlooked aspect is energy rebates. In AU, using certified, high-efficiency PSUs may qualify for sustainability incentives. Pairing the DBS-110-3PC-AU-K9= with Cisco’s EnergyWise software could amplify ROI through real-time power monitoring. Ultimately, this component isn’t just about power—it’s about aligning infrastructure with regulatory and operational priorities.
