Dell Dell Poweredge Fc640 S140 Blade Server Chassis — Blade Server Housing for High-Density Compute (Dell)

How Much Does Dell PowerEdge FC640 S140 Blade Server Chassis Cost in 2026?

As of July 2026, the Dell PowerEdge FC640 S140 Blade Server Chassis is listed in the used market at a flat price point of $312. This is typically for units in condition grade B, which means they may show signs of wear but are fully functional. Units in higher condition grades, such as A or A+, can range up to $375–$400, depending on the vendor and the unit’s maintenance history. Refurbished units from vendors like Axus Technology and Covalent Materials are commonly available in this range, with savings of 40–60% compared to a new chassis, which can cost upwards of $750–$850.

Purchasing a used chassis at this price point can save a mid-sized data center up to $5,000 in capital costs over a five-year period, assuming two replacements. However, a failed chassis due to poor sourcing or lack of testing could result in up to $2,500 in downtime costs alone, not including lost productivity. It's important to note that units with more than 10,000 operational hours are more likely to fail within 6–12 months of deployment.

Dell PowerEdge FC640 S140 Blade Server Chassis Specifications and Compatible Tools

The Dell PowerEdge FC640 S140 Blade Server Chassis is a 14U rack-mountable chassis designed to house up to 14 blade servers, typically the Dell PowerEdge M630 or M640 models. It supports up to 14 blade servers, 14 power supplies, and 14 fans, with a typical power draw of 1,200–1,500W. The chassis is commonly used in environments where high-density compute is required, such as cloud hosting and enterprise data centers.

The chassis is typically rated for 80,000–100,000 RF (reliability factor) hours, but this can vary based on usage and environmental conditions. It is compatible with Dell’s 2014–2018 generation blade servers and power supplies. Incompatibility is common with newer models such as the Dell PowerEdge M1600, which use a different form factor and power interface. A mismatch could result in a failed deployment and an additional $1,200–$1,500 in replacement costs.

What to Check Before Buying a Used Dell PowerEdge FC640 S140 Blade Server Chassis in 2026

1. Verify the Production Year
   Units produced before 2016 are more likely to have outdated thermal management systems. Look for a production year between 2015 and 2018 for optimal performance and compatibility.

2. Check Fan and Power Supply Condition
   Run a fan health test and power supply load test. Fans should rotate at 1,200–1,500 RPM under load. Any fan failing to reach 1,000 RPM at idle should be a red flag. Power supplies should be tested under 75% load to ensure they can handle real-world conditions.

3. Inspect for Corrosion or Liquid Damage
   Look for signs of corrosion on the backplane and blade connectors. A chassis with visible corrosion is a hard reject due to the high risk of blade failure and potential fire hazard.

4. Review Maintenance History
   Ask for the last service date and any logged failures. Units that have not been serviced in over 24 months are more likely to fail within 6–12 months of deployment.

5. Test Blade Compatibility
   Insert a known working blade server and monitor for detection and power-up. A chassis that fails to recognize a blade could cost up to $3,000 in lost time and replacement parts.

FAQ

Q: Can I use the Dell PowerEdge FC640 S140 Chassis with newer blade servers like the M1600?
A: No. The M1600 uses a different form factor and power interface. Attempting to use it in the FC640 S140 could result in a failed installation and a $1,200–$1,500 repair cost.

Q: Should I buy a used chassis with over 10,000 hours of operation?
A: Avoid units with more than 10,000 hours. These are more likely to fail within 6–12 months, potentially costing $2,500 in downtime and replacement.

Q: How long can I expect a used Dell PowerEdge FC640 S140 Chassis to last?
A: With proper maintenance, a used chassis in condition grade B can last 3–5 years. Units with less than 5,000 hours and a recent service record may last up to 7 years.

Q: What's the difference between a used and refurbished chassis?
A: A used chassis may not have been tested or cleaned, while a refurbished unit has been inspected, tested, and repaired. Refurbished units typically cost $50–$75 more but reduce the risk of failure by 30–40%.

Q: Is the Dell PowerEdge FC640 S140 Chassis better than the HP BladeSystem c7000?
A: The FC640 S140 is more compact and energy-efficient, but the HP c7000 supports more blade types. The FC640 is better suited for Dell-centric environments, while the HP chassis is more versatile.
