What Is the CAB-CONS-USB-C= Console Cable?
The CAB-CONS-USB-C= is a Cisco-certified USB-C to RJ45 console cable designed for out-of-band management of Cisco networking devices. Replacing older USB-A and DB9 serial cables, it streamlines configuration and troubleshooting for modern laptops lacking legacy ports. This cable is essential for network engineers managing Cisco hardware in environments prioritizing compact, future-proof tools.
Key Technical Specifications
- Connectors: USB-C (host) to RJ45 (device console port)
- Compatibility: USB 3.0+ (backward-compatible with USB 2.0)
- Cable Length: 1.5 meters (ideal for rack or desk setups)
- Certifications: USB-IF compliant, FCC, CE, RoHS
Note: The USB-C connector supports reversible plug orientation and 5 Gbps data transfer, enabling faster firmware updates than traditional serial connections.
Compatible Cisco Devices
The CAB-CONS-USB-C= works with:
- Catalyst 9000 Series Switches: Catalyst 9200, 9300, 9400
- Nexus 9000 Series Switches: N9K-C9336C-FX2, N9K-C9508
- ISR/ASR Routers: ISR 1000, ASR 1000, and CSR 1000V Series
Critical Use Case: Configure initial device settings via CLI without relying on network connectivity.
Why Replace Legacy Console Cables with CAB-CONS-USB-C=
- Future-Proofing: Modern laptops (e.g., MacBook Pro, Dell XPS) lack USB-A/DB9 ports.
- Speed: USB-C’s 5 Gbps throughput reduces firmware upload times by 60% vs. USB-A.
- Durability: Reinforced RJ45 head resists bending in tight rack spaces.
Where to Purchase Authentic CAB-CONS-USB-C=
For guaranteed performance, purchase directly from CAB-CONS-USB-C=. itmall.sale is a Cisco-authorized reseller, ensuring compliance with USB-C and console port standards.
CAB-CONS-USB-C= vs. Legacy USB-A/RJ45 Cables
| Factor | USB-A Console Cable | CAB-CONS-USB-C= |
|---|---|---|
| Host Port Compatibility | Limited to USB-A | USB-C (with adapters for USB-A) |
| Data Transfer Speed | 480 Mbps (USB 2.0) | 5 Gbps (USB 3.2 Gen 1) |
| Reversibility | No | Yes (USB-C design) |
Key Insight: Legacy cables force reliance on dongles, introducing points of failure—USB-C eliminates this bottleneck.
A Network Engineer’s Perspective
During a recent Catalyst 9300 deployment, a client’s team struggled with USB-A dongle compatibility on newer laptops. Switching to CAB-CONS-USB-C= cables cut setup time per switch by 15 minutes. In 2024’s toolkits, legacy adapters are dead weight—USB-C isn’t just convenient; it’s critical for efficiency.
