Hp Hpe 785341 001 Synergy 20G Interconnect Link Module — High-Performance Networking Component (HP)

How Much Does HPE 785341-001 Synergy 20G Interconnect Link Module Cost in 2026?

As of July 2026, the HPE 785341-001 Synergy 20G Interconnect Link Module is priced in the range of $62–$62, typically for a used or refurbished unit in condition grade B. This price point is consistent across most secondary market vendors, including Ferrotec and Axus Technology, which are known for handling high-quality HP networking components. Compared to a new unit, which can cost between $140–$180, this represents a savings of 40–60%.

The cost of failure is significant: a single defective module can cause a rack of HP Synergy blades to go offline, costing an average of $1,200–$1,500 in downtime per hour. That’s why it’s critical to source from a trusted vendor. Modules in condition grade B are generally functional but may show signs of wear or have limited warranty coverage. Always verify the part’s condition and test history before purchase.

HPE 785341-001 Synergy 20G Interconnect Link Module Specifications and Compatible Tools

The HPE 785341-001 is a 20G interconnect link module designed for HP Synergy 4820 and 6820 Switches. It typically supports up to 1000 hours of continuous operation without failure, though real-world performance may vary based on environmental conditions. The module is commonly used in data centers and cloud environments where high-speed, low-latency connectivity is essential.

This part is compatible with HP Synergy 4820 and 6820 Switches, typically deployed in 2018–2021 production models. It is not compatible with the HPE 785341-002 or any 40G interconnect modules. Using an incompatible module can result in a complete fabric failure, which can bring down an entire rack of compute modules and cost upwards of $3,000 in lost productivity.

Always verify compatibility with your specific switch model and firmware version before installation.

What to Check Before Buying a Used HPE 785341-001 Synergy 20G Interconnect Link Module in 2026

1. Verify Production Year: Modules produced before 2019 may have lower reliability due to early firmware issues. Avoid parts older than 2017.

2. Check RF Hours or Cycles: Look for modules with less than 500 RF hours or 200 insertion cycles. Units with more than 800 hours are typically past their useful life and may fail within weeks.

3. Test with Loopback and Link Test: Use a loopback test to verify signal integrity and a link test to confirm that the module can establish a stable connection. A failed loopback test is a hard reject.

4. Inspect Physical Condition: Look for bent pins, corrosion, or cracked PCBs. These can lead to intermittent failures and costly rework.

5. Request Test Logs: A reputable vendor should provide test logs showing the module passed HP’s standard diagnostics. Without this, the risk of failure is too high.

Failing to inspect these factors can result in a defective module, which could cost $1,500–$2,000 in downtime and replacement costs.

FAQ

Q: Can I use the HPE 785341-001 with a 40G switch?

A: No. The 785341-001 is a 20G module and is not compatible with 40G switches such as the HPE 785341-002. Using it in a 40G environment can cause a complete fabric failure and cost up to $3,000 in downtime.

Q: Should I buy a used HPE 785341-001 module if it has over 600 RF hours?

A: No. Modules with over 600 RF hours are approaching or past their expected lifecycle and are more likely to fail within 30–60 days. Stick to units with under 500 hours.

Q: How long can I expect a used HPE 785341-001 to last in a production environment?

A: On average, a used module in condition grade B with under 500 RF hours can last 6–12 months in a typical data center. Modules used in high-traffic environments may fail sooner.

Q: Is the HPE 785341-001 still supported by HP in 2026?

A: HP officially supports the 785341-001 through 2027. However, spare parts and firmware updates may become harder to obtain after 2026, so sourcing a used module now is advisable.

Q: What’s the difference between HPE 785341-001 and 785341-002?

A: The 785341-001 is a 20G module, while the 785341-002 is a 40G module. They are not interchangeable. Using the wrong module can cause a full switch failure and cost $2,000–$5,000 in downtime and repairs.
