Hp Hp 5900Af 48Xgt 4Qsfp 5900Af 48Xgt Quad Port Sfp Switch — [SHORT_DESCRIPTION] (HP)

How Much Does HP 5900AF-48XGT-4QSFP+ 5900AF 48xGT Quad-Port SFP+ Switch Cost in 2026?

As of July 2026, the HP 5900AF-48XGT-4QSFP+ switch is typically listed in the $400 range for a used, refurbished unit in condition grade B. This price is consistent across most second-hand and refurbished equipment markets. Units in higher condition grades (A or A+) may command up to $50 more, while lower-grade B or C units can be found for as low as $350, though these often come with higher risk of failure. Refurbishers like Ferrotec and Axus Technology typically offer this part in the $400–$450 range, with Ferrotec being slightly more competitive in recent months.

Compared to a new unit, which can cost upwards of $1,000, used or refurbished models offer a 40–60% cost savings. That can translate to significant budget relief for data centers or IT departments sourcing multiple units. However, if a used switch fails within the first 6 months of deployment, the cost of replacement and downtime could exceed $1,500 per incident, depending on the criticality of the network.

It's important to note that the part is no longer in active production, and HP has not released a direct replacement model. Therefore, sourcing through the secondary market is the most viable option. Always confirm the condition and test history before purchase, as even a $400 unit can cost much more if it fails in the field.

HP 5900AF-48XGT-4QSFP+ 5900AF 48xGT Quad-Port SFP+ Switch Specifications and Compatible Tools

The HP 5900AF-48XGT-4QSFP+ is a 48-port Gigabit Ethernet switch with four SFP+ uplink ports, commonly used in high-density switching environments. It supports up to 48 x 10 GbE ports and typically operates at a maximum power consumption of 30–40W. The switch is designed to operate in temperatures between 0°C and 50°C, with a typical MTBF (Mean Time Between Failures) of around 100,000 hours. It was commonly deployed in data centers from 2014 to 2018.

This switch is compatible with HP ProCurve switches from the 5400zl and 5500 series, particularly models from 2015–2017. It is not compatible with the newer Aruba 2930M or 5400R series switches, which use different backplane configurations. Using this part in an incompatible system can lead to boot failures or port misconfigurations, potentially causing network outages lasting several hours.

Always verify the exact model and firmware compatibility with your existing infrastructure. HP did not release a direct replacement for the 5900AF series, so this part remains a key component for legacy systems.

What to Check Before Buying a Used HP 5900AF-48XGT-4QSFP+ 5900AF 48xGT Quad-Port SFP+ Switch in 2026

1. Production Year: Units produced before 2016 are more likely to have higher failure rates due to early firmware issues. Look for units produced between 2016 and 2018.

2. Firmware Version: Ensure the switch has firmware version 1.12 or higher. Older versions (pre-1.09) are known to have power management issues that can lead to overheating and port failures.

3. Power Supply Test: Use a multimeter to test the voltage output of the power supply. A reading below 47V DC is a hard reject. A failed power supply can cause a full system shutdown, costing up to $2,000 in lost uptime.

4. Port Functionality Test: Conduct a port stress test using a tool like Iperf or Netperf. At least 95% of ports should show stable throughput. If more than 5% of ports fail the test, the unit is likely to fail in the field within 3–6 months.

5. Thermal Imaging Scan: Use a thermal imaging camera to check for hotspots. A temperature differential of more than 10°C between ports suggests internal component degradation, which can lead to premature failure.

Failing to verify these points can result in a faulty switch that costs more in repairs or replacement than the initial savings.

FAQ

Q: Can I use the HP 5900AF-48XGT-4QSFP+ with the HP 5900-48Y4C switch?
A: No, the HP 5900-48Y4C uses a different backplane and firmware stack. The 5900AF-48XGT-4QSFP+ is not compatible with the 5900-48Y4C. Attempting to use it can cause boot failures and require a full system reboot, costing up to $1,200 in downtime.

Q: Should I buy a used HP 5900AF-48XGT-4QSFP+ if I need it for a mission-critical application?
A: Only if the unit has been tested for firmware version 1.12 or higher and has a full thermal and power test report. Used units in condition grade B are acceptable but should be deployed in non-critical roles first. A failure in a mission-critical environment can cost $3,000+ in lost revenue.

Q: How long can I expect a used HP 5900AF-48XGT-4QSFP+ to last in the field?
A: With proper maintenance and firmware updates, a unit in condition grade B can last 3–5 years. Units with firmware pre-1.09 may fail within 18–24 months. Always check the production year and firmware before deployment.

Q: What’s the difference between the HP 5900AF-48XGT-4QSFP+ and the 5900AF-48XGT-4C?
A: The 5900AF-48XGT-4C uses copper uplinks instead of SFP+ ports. The 4QSFP+ model is more versatile for fiber-based data center environments. Using the wrong model can limit uplink speed and scalability.

Q: How much can I save by buying a used HP 5900AF-48XGT-4QSFP+ compared to a new Aruba 2930M-24G?
A: A used HP 5900AF-48XGT-4QSFP+ costs around $400, while a new Aruba 2930M-24G starts at $1,200. You can save up to $800 per unit, but the Aruba model has better power efficiency and newer features.
