A9XX-PWR-CBL-MGMT= Defined: Purpose in Power Infrastructure
The Cisco A9XX-PWR-CBL-MGMT= is a cable management kit designed for Cisco ASR 9000 Series routers. It organizes and secures power supply cables within the chassis, reducing clutter, improving airflow, and minimizing accidental disconnections in high-density deployments. This accessory is critical for maintaining NEBS compliance in telecom environments, where cable strain relief and thermal efficiency are non-negotiable.
Key Features and Compatibility
- Material: Flame-retardant polymer brackets with stainless steel retention clips (UL 94 V-0 rated).
- Capacity: Manages up to 8 power cables per chassis, compatible with A9KV-V2-AC= and A9KV-V2-DC-A= PSUs.
- Installation: Tool-less design for quick mounting in ASR 9904, ASR 9912, and ASR 9920 chassis.
- Compliance: Meets GR-63-Core seismic and vibration standards for carrier-grade deployments.
Addressing User Concerns
Q: Does it work with third-party power supplies?
No. The clip spacing and cable diameter tolerances are optimized for Cisco’s A9KV series PSUs. Third-party cables may not fit securely, risking strain on connectors.
Q: Can it be installed post-deployment without downtime?
Yes. The tool-less design allows installation during maintenance windows. However, fully de-rack the chassis to avoid bending power cables during retrofitting.
Deployment Best Practices
- Cable Routing: Follow horizontal/vertical lacing patterns to avoid blocking airflow to line cards.
- Strain Relief: Leave a 2-inch service loop at the PSU end to accommodate chassis sliding.
- Inspection: Check clip tension every 12 months—over-tightening can deform cables over time.

Why Neglecting Cable Management Risks SLAs
During a Tier 4 data center audit, I encountered an ASR 9912 plagued by intermittent PSU failures—traced to cables sagging onto a line card’s heat sink. Installing the A9XX-PWR-CBL-MGMT= resolved the overheating and eliminated false hardware alerts. While cable management seems trivial, this kit exemplifies how meticulous infrastructure design underpins uptime. For operators scaling edge or core nodes, it’s a low-cost safeguard against high-impact failures.
