ARRIS PathTrak CPU-5500 – Controller Module for Return‑Path Monitoring Chassis

The PathTrak CPU-5500 is the control brain for ARRIS PathTrak return‑path monitoring systems, coordinating receiver modules and providing reliable network access to your headend monitoring platform. From my experience, operators value it for keeping large HFC plants visible and manageable without babysitting the rack. You might notice that once it’s in the chassis, system responsiveness and module coordination are typically more stable, especially during high‑event periods.

Key Features

• Centralized control for PathTrak chassis – Coordinates receiver modules and system tasks to keep monitoring consistent across nodes.
• Network connectivity – Designed for headend integration, typically providing Ethernet access to the PathTrak server environment.
• Backplane-powered module – No external power brick; simplifies cabling and keeps the rack clean.
• Service-friendly – Modular, field-replaceable design helps reduce MTTR in busy headends.
• Firmware upgradability – Supports firmware updates to align with system software revisions and security practices.
• No RF break‑in – Handles control and data; RF paths remain on dedicated receiver modules, avoiding signal intrusion.

Technical Specifications

Application Fields

The CPU-5500 is used in cable TV and broadband headends to manage return‑path spectrum monitoring across HFC networks. Typical scenarios include proactive noise hunting, upstream ingress detection, node performance trending, and post‑maintenance verification. MSOs, regional fiber‑coax operators, and network operations centers deploy it to keep upstream noise under control and shorten time‑to‑repair for field teams.

Advantages & Value

• Reliability – Stable control of monitoring modules helps avoid data gaps during peak hours.
• Compatibility – Purpose‑built for the PathTrak ecosystem, which reduces integration risk compared with mixed vendor setups.
• Service continuity – Modular design allows quick swaps, often without long outages in the monitoring layer.
• Lower OPEX – Centralized management and fewer truck rolls for verification; in many cases you’ll see faster triage on upstream issues.
• Supportable lifecycle – Firmware update path and widely‑used platform mean parts and expertise are easier to source.

Installation & Maintenance

• Environment – Install in a suitable PathTrak chassis within a 19″ rack; maintain front‑to‑back airflow and keep ambient within typical headend ranges.
• Power & grounding – Use a stable, conditioned supply feeding the chassis; keep bonding/ground consistent with plant standards.
• Wiring – Seat the module firmly on the backplane; use short, labeled Ethernet patching to your management switch.
• Safety – Observe ESD protection when handling modules; de‑energize the chassis if your site procedures require it.
• Routine care – Periodically clean intake areas, validate CPU status LEDs, and back up configuration. Plan firmware updates during maintenance windows.
• Post‑install checks – Confirm module recognition in the PathTrak software and verify receiver synchronization before closing the ticket.

Quality & Certifications

ARRIS headend modules typically meet major regional compliance requirements for telecom and EMC. It appears that the CPU-5500 is supplied to operators with CE and RoHS conformity and undergoes standard production quality controls. Manufacturer hardware warranty is commonly 12 months; our platform provides a 365‑day warranty on this item for added assurance.
