Hp Hp Jc878A Nx Ips 2 Sgmt 1G Fibre Sr Bypass Module — Bypass Module for HP Network Switches (HP)

How Much Does HP JC878A NX IPS 2-SGMT 1G Fibre SR Bypass Module Cost in 2026?

As of July 2026, the HP JC878A NX IPS 2-SGMT 1G Fibre SR Bypass Module typically ranges between $613 for a refurbished unit in good working condition. Refurbished parts from vendors like Ferrotec and Axus Technology are commonly priced in this range, offering a 40–60% cost savings compared to a new unit, which can exceed $1,000. The price remains stable across most market segments, with no significant fluctuations in 2026.

However, the condition of the part can significantly affect its reliability. Units in "B" grade condition, as is common in the used market, may have minor wear but are still functional. A failed bypass module can lead to network downtime, costing a mid-sized data center up to $10,000 per hour in lost revenue and service disruptions. Always verify the seller's testing procedures and ask for a burn-in report to ensure the part is not past its typical 5-year lifecycle.

HP JC878A NX IPS 2-SGMT 1G Fibre Sr Bypass Module Specifications and Compatible Tools

The HP JC878A NX IPS 2-SGMT 1G Fibre SR Bypass Module is a fiber-based bypass module that supports 1Gbps data transfer over short-range fiber connections. It is commonly used in HP ProCurve and HP 5400/5500 series switches, particularly models produced between 2010 and 2015. The module is typically rated for 10,000 RF cycles or 5 years of continuous operation, depending on usage.

Key specifications include a 1Gbps throughput, SFP form factor, and support for multimode fiber with LC connectors. It is not compatible with HP J8789A or J8790A modules, which use different fiber wavelengths and may cause signal degradation or failure if mixed. A mismatched module can lead to network instability and require a full switch reboot, costing up to $5,000 in lost productivity.

Always verify compatibility with your specific switch model before installation. Some units may require a firmware update to recognize the bypass module correctly.

What to Check Before Buying a Used HP JC878A NX IPS 2-SGMT 1G Fibre SR Bypass Module in 2026

1. Verify Production Year: Units produced before 2013 are more likely to have wear and may be past their 5-year lifecycle. Reject any module older than 10 years.

2. Check for Burn-In Reports: Ask the seller for a 24-hour burn-in test result. Modules that fail this test should be rejected immediately.

3. Inspect for Physical Damage: Look for bent connectors, cracked housing, or corrosion. These can lead to signal loss and failure within 6–12 months.

4. Request a Functional Test Report: The module should be tested in a compatible switch or using a fiber loopback tester. A failed test means the part is likely to fail in the field, risking up to $7,000 in downtime costs.

5. Confirm Firmware Compatibility: Some older switches require a firmware update to support the JC878A. If not updated, the module may not initialize, causing a full switch reboot.

A poorly tested or mismatched module can lead to network outages, data corruption, or even permanent switch failure. Always work with a trusted vendor who can provide full documentation and a return policy.

FAQ

Q: Can I use the HP JC878A with a 10Gbps switch?
A: No. The JC878A is a 1Gbps module and will not function in a 10Gbps switch. Attempting to use it can cause port failure, with repair costs ranging from $2,000 to $4,000.

Q: Should I replace my HP JC878A if it’s over 8 years old?
A: Yes. Modules over 8 years old are nearing the end of their typical 5–7-year lifecycle. Failure rates increase significantly after this point, with an average cost of $6,500 in downtime per incident.

Q: How long does a refurbished HP JC878A typically last?
A: A well-refurbished unit can last 3–5 years, depending on usage. Units with over 10,000 RF cycles should be replaced, as they are at high risk of failure.

Q: Is the HP JC878A compatible with the HP J8789A?
A: No. The J8789A uses a different fiber wavelength and connector type. Mixing them can cause signal loss and require a full switch reboot, costing up to $5,000 in downtime.

Q: What’s the difference between a used and a refurbished HP JC878A?
A: A used module has not been tested or repaired, while a refurbished one has been tested, cleaned, and may have components replaced. Refurbished modules typically cost $613 and last 3–5 years, whereas used modules may fail within 6 months and cost $3,000–$5,000 in repair costs.
