HP DACs (Direct Attach Cables) are networking products and computer accessories used in data centers and enterprise networks to establish high-speed connections between networking devices, such as switches, routers, and servers. HP DACs are a type of networking cable designed for short-range, high-speed data transmission within data center racks or between closely located network devices. Here's what you need to know about HP DACs:

High-Speed Connectivity: HP DACs are designed to support high-speed data transmission, typically using protocols like Ethernet or InfiniBand. They come in various versions, including 10G, 25G, 40G, and 100G, depending on the specific networking requirements.
Form Factor: HP DACs are often available in various form factors, such as SFP+ (Small Form-Factor Pluggable Plus) and QSFP (Quad Small Form-Factor Pluggable), to accommodate different network interfaces and port types.
Direct Attach: The "Direct Attach" in DAC refers to the direct connection between two networking devices, such as a switch and a server, without the need for additional networking equipment like transceivers or fiber optic cables.This results in a cost-effective and low-latency solution for short-distance connections.
Compatibility: HP DACs are typically designed to be compatible with HP networking equipment, but they may also work with other networking devices that support the same standards and form factors. It's important to check compatibility with your specific devices before purchasing.
Length Variability: HP DACs come in various cable lengths to accommodate different data center configurations. Common cable lengths range from a few meters to longer distances, depending on the networking standard and use case.
Data Center Use: HP DACs are commonly used in data centers and enterprise environments where high-speed, short-distance connections are required for efficient data transmission and network performance. They are often used for server-to-switch connections or switch-to-switch connections within the same rack.
Reliability: HP is known for producing high-quality networking equipment, and their DACs are no exception. These cables are designed to meet industry standards for reliability and performance, ensuring that data flows smoothly between connected devices.
Cost-Effective: HP DACs offer a cost-effective solution for short-range connections when compared to using separate transceivers and fiber optic cables. This can help organizations save on networking infrastructure costs.

HP DACs play a crucial role in modern data center and networking environments, providing a reliable and cost-effective solution for establishing high-speed connections between networking devices. When considering the use of HP DACs, it's essential to assess your specific networking requirements and ensure compatibility with your existing hardware.

User questions & answers

Question:	Is this compatible with HP E3800 and others that do not allow 3rd-party transceivers
Answer:	No. The device is only rated to 1800W of power (120V/15A). You would definltely overload it. You need to find an AC outlet with at least 3500W capacity. And ideally don't connect anything else to it. I've noticed that even with an iPad connected to the USB outlets, the plastic becomes quite war. If you need surge protection, you should be looking at more professional/industrial/higher capacity equipment, such as that made by Furman, which pro-AV companies use.
Question:	Can the sfp+ part be removed (on one side) to fit into a "normal" rj45 gb port
Answer:	It can. Has 4 screw mounts in the corners.
Question:	Can the sfp+ be removed (on one side) to fit into a "normal" rj45 port
Answer:	MANUFACTURER RESPONSE: For protection from normal background surges during electrical storms, this will do the job. However, in the event of a close proximity or direct lightning strike, this surge protector (and any surge protector that you can buy) will not protect against damage. Lightning jumps miles through the air discharging billions of joules of energy, a small surge suppression device stands no chance against that sort of event. The best way to protect expensive electronics during a lightning storm is to remove them from the ground path by unplugging them from the wall. There are home lightning protection systems out there, but even these have no guarantee of protection.
Question:	Is it compatible with hp a5820x-24xg
Answer:	They are for electronics that have a big square or rectangular plug.
