Hp Hp 663658 001 6125Gxg Ethernet Blade Switch — High-Performance Blade Switch for HP BladeSystem (HP)

How Much Does HP 663658-001 6125G/XG Ethernet Blade Switch Cost in 2026?

As of July 2026, the HP 663658-001 6125G/XG Ethernet Blade Switch is listed in the used/refurbished market at a price point of $127. This is a single-tier pricing model, meaning the cost is consistent regardless of condition grade, though most units in this price range are typically rated as B-grade or similar. Refurbished units from trusted vendors like Ferrotec and Axus Technology are commonly available in this range, offering a 40–60% cost savings compared to a new unit, which would typically retail for $250–$300.

The cost of failure is significant: if a blade switch fails in a live HP BladeSystem enclosure, the downtime can range from 8–12 hours, depending on the data center’s maintenance schedule. This can translate to $1,500–$3,000 in lost productivity for a mid-sized enterprise. Additionally, a failed blade switch can disrupt up to 16 blade servers in the enclosure, depending on configuration.

It’s important to note that while the price is low, the condition caveat is real. Units in this price range are typically used and may have limited remaining lifecycle. Always request a detailed inspection report before purchase.

HP 663658-001 6125G/XG Ethernet Blade Switch Specifications and Compatible Tools

The HP 663658-001 6125G/XG Ethernet Blade Switch is a 1U blade switch designed for HP BladeSystem c3000 and c7000 enclosures. It supports 16 10/100/1000BASE-T ports and two 10 GbE SFP+ ports, with a typical switching capacity of 32 Gbps. The unit is commonly rated for 50,000 RF-hours of operation and is typically compatible with HP BladeSystem enclosures manufactured between 2006 and 2012.

This switch is not compatible with newer HP BladeSystem models such as the c3000 Gen10 or c7000 Gen10, due to differences in backplane architecture and power requirements. Specifically, it is not compatible with part number 663659-001 or newer blade switches.

Failure of this switch can lead to a complete loss of network connectivity for up to 16 blade servers, resulting in extended downtime and potential data loss if no redundancy is in place. Always verify compatibility with your enclosure before installation.

What to Check Before Buying a Used HP 663658-001 6125G/XG Ethernet Blade Switch in 2026

1. Production Year: Ensure the unit was manufactured between 2006 and 2012. Units older than 2005 may have exceeded their 50,000 RF-hour lifecycle and are more likely to fail.

2. Power Supply Test: Use a multimeter to verify that the internal power supply delivers the correct 12V and 3.3V rails. A failed power supply can cause a complete system outage, costing $2,000–$4,000 in downtime and repair.

3. Port Functionality Test: Conduct a port loopback test using a standard Ethernet cable. At least 14 of the 16 ports should be functional. Reject the unit if more than two ports fail this test.

4. Firmware Version: Confirm the firmware is at least version 1.2.0. Older firmware versions may not support newer blade server configurations and can lead to interoperability issues.

5. Physical Inspection: Look for signs of overheating, such as discolored PCBs or warped components. Units with physical damage are more likely to fail within 3–6 months of installation.

Buying a faulty unit can lead to a complete network outage in your BladeSystem enclosure, with downtime costs ranging from $1,500 to $3,000. Always request a full diagnostic report and return policy before purchasing.

FAQ

Q: Can I use the HP 663658-001 in a Gen10 BladeSystem?

A: No. The 663658-001 is not compatible with HP BladeSystem Gen10 enclosures due to differences in backplane architecture. It is only compatible with c3000 and c7000 enclosures manufactured before 2013.

Q: Should I replace the 663658-001 with a newer model?

A: If your enclosure is older than 2010 and still in active use, it may be more cost-effective to retain the 663658-001. Newer models like the 663659-001 cost 30–50% more and may require firmware upgrades on your blade servers.

Q: How long can I expect a used 663658-001 to last?

A: A well-maintained unit typically lasts 3–5 years in a controlled data center environment. Units with more than 40,000 RF-hours should be considered high-risk and may fail within 6–12 months.

Q: What’s the difference between the 6125G and 6125XG models?

A: The 6125G supports 1 GbE ports only, while the 6125XG includes two 10 GbE SFP+ ports. If your setup requires 10 GbE connectivity, the XG model is necessary.

Q: How much can I save by buying used vs new?

A: You can save 40–60% by purchasing a used or refurbished 663658-001. New units from HP typically cost between $250 and $300, depending on configuration and warranty.
