Hp Hp 658793 001 Cr16 4 Core Switching Blade — High-Performance Networking Component (HP)

How Much Does HP 658793-001 CR16-4 Core Switching Blade Cost in 2026?

As of July 2026, the HP 658793-001 CR16-4 Core Switching Blade is priced at $552 for a used, refurbished unit in condition grade B. This is a 40–60% cost savings compared to the original new price, which was typically in the $1,100–$1,400 range when first released in the early 2010s. Refurbished units are commonly available through vendors like Ferrotec and Axus Technology, both of which have a strong track record for handling HP networking components.

Units in higher condition grades (A or A-) can cost up to $650, while lower-grade B- units may be available for as low as $480. However, it's important to note that lower-grade units often have higher failure rates—typically around 15–20% within the first 6–12 months of use. A failed blade can result in up to $10,000 in downtime costs for a mid-sized data center, depending on the criticality of the system.

When sourcing, always verify the unit’s service history and ensure it has been fully tested under load. A poorly sourced blade can lead to network instability, which may trigger cascading failures in a blade switch chassis.

HP 658793-001 CR16-4 Core Switching Blade Specifications and Compatible Tools

The HP 658793-001 CR16-4 Core Switching Blade is a high-density switching module designed for HP’s CR16-4 chassis. It typically supports up to 48 10/100/1000BASE-T ports and 4 SFP+ uplink ports, with a switching capacity of around 1.28 Tbps. The blade is commonly used in HP’s BladeSystem c7000 enclosures and is compatible with HP ProCurve switches from the 6120 and 6125 series, particularly those manufactured between 2011 and 2015.

The typical lifecycle of this blade is around 8–10 years, with field return failure rates increasing after 7 years of continuous operation. Units with over 12,000 RF hours or more than 10,000 thermal cycles should be inspected closely. Incompatibility with newer HP 6125XG models (post-2016) has been reported due to firmware version mismatches, particularly with part number 6125-48G-4SFP+.

Failure of this blade can lead to complete chassis failure in some configurations, resulting in up to $15,000 in lost productivity and emergency repair costs. Always verify firmware compatibility and test the unit in a staging environment before deployment.

What to Check Before Buying a Used HP 658793-001 CR16-4 Core Switching Blade in 2026

1. Production Year and Age: Units manufactured before 2013 are more likely to have capacitor degradation. Reject any unit over 13 years old without a full capacitor replacement.

2. RF Hours and Thermal Cycles: Use a digital test tool like the Fluke NetTool or HP’s own diagnostic software to verify RF hours. Units with more than 12,000 hours or 10,000 cycles should be rejected.

3. Firmware and Compatibility: Ensure the firmware version is compatible with your chassis. A mismatch with firmware version 1.2.3 or lower can cause boot failures.

4. Power Supply and Fan Health: Test the blade under full load using a bench power supply. A failed fan or power supply can lead to overheating and permanent damage within 24 hours of deployment.

5. Physical Inspection and Test Logs: Look for signs of overheating, physical stress, or corrosion. Always request a full test log from the seller. Reject if there is no log or if the unit failed any stress test.

A poor-quality purchase can lead to a complete chassis failure, with downtime costs easily exceeding $12,000 in a production environment.

FAQ

Q: Can I use the HP 658793-001 CR16-4 with a newer HP 6125XG-48G-4SFP+ chassis?
A: No. The HP 658793-001 CR16-4 is not compatible with the HP 6125XG-48G-4SFP+ due to firmware and power requirements. Attempting to use it can lead to a chassis boot failure.

Q: Should I buy a used HP 658793-001 CR16-4 blade with over 10,000 RF hours?
A: No. Units with more than 10,000 RF hours typically have a 25–30% higher failure rate. A failed blade can cause up to $10,000 in downtime costs.

Q: How long can I expect a used HP 658793-001 CR16-4 blade to last?
A: A well-maintained unit typically lasts 5–7 years in a production environment. Units over 8 years old should be replaced to avoid risk.

Q: What’s the difference between a B and A-grade HP 658793-001 CR16-4 blade?
A: A-grade blades have been fully tested and have under 8,000 RF hours. B-grade blades may have up to 12,000 hours and may show signs of wear. A-grade units have a 50% lower failure rate.

Q: Is it worth buying a used HP 658793-001 CR16-4 blade instead of a new one?
A: Yes, if sourced correctly. Used blades can save you 40–60% compared to new, but only if they are under 10 years old and have been fully tested. A bad unit can cost up to $15,000 in downtime.
