What Is the Difference Between Plenum and Riser Cable

Are you looking to buy the next ethernet cables but unable to differentiate between the plenum and the riser cables? Or you are a novice and can’t decide whether Cat6 Plenum is better for you or Cat6 Riser? You need not worry as we have got you covered.

Before going into the difference, let’s first know what plenum and riser cables are. 

What Is Plenum Cable?

A cable bearing a CMP mark on the outer surface of its jacket is characterized as a plenum cable. In case you are wondering, let us tell you that CMP stands for Communications Multipurpose Cable, Plenum, and it is the highest rating for jacket material for ethernet cables. These cables are meant for installation in the plenum spaces of the buildings. Plenum spaces are empty spaces between the ceilings or the floors of the buildings. These spaces are meant to facilitate air circulation for air conditioning and heating systems. These spaces are at greater risk of fire eruption, and this is where a plenum-rated comes in handy. 

 

The plenum cables are manufactured using supreme quality polyvinyl chloride. In case of fire eruption, these cables halt fire progression because of their fire-retardant properties. Also, when exposed to fire, these cables emit no smoke or dangerous gases. Because of the thick jacket, these cables provide top-notch protection against alien crosstalk, near-end crosstalk, and electromagnetic interference thus, keeping the integrity of your data intact. These cables are also UV resistant. The following types of plenum cables are available in the market right now: Cat5e Plenum, Cat6 Plenum, and Cat6a Plenum.

These cables, too, meet all types of industry standards, including FCC, CE, CSE, ISO/IES, and are in compliance with RoHS and TIA/EIA. 

What is Riser Cable?

A riser ethernet cable is identified by the CMR market printed on the outer surface of its jacket – CMR here stands for Communications Multipurpose Cable, Riser. The CMR-rated ethernet cables are also made using fine-quality polyvinyl chloride. As their name suggests, these cables are meant for installation in the riser or vertical spaces of the buildings.

Riser-rated cables also have fire retardant properties, and they too halt fire progression just like their plenum counterparts. When it comes to protection against electromagnetic interference, near-end crosstalk, and alien crosstalk, riser-rated have excellent protection against them. They, too, keep the integrity of your data intact. You can find the following types of riser cables in the market: Cat5e Riser, Cat6 Riser, and Cat6a Riser

These cables, too, meet all types of industry standards, including FCC, CE, CSE, ISO/IES, and are in compliance with RoHS and TIA/EIA. 

Difference Between Plenum & Riser Cables

  1. Jacket Material: The main difference between the riser and plenum ethernet cables is that of jacket material. Plenum cables enjoy CMP ratings. It is the highest rating when it comes to ethernet jackets. These cables are made from the best quality polyvinyl chloride. Riser cables come with CMR ratings, and it is the second-best jacket ratings in the ethernet cable industry. Although riser-rated jackets are also made from good quality polyvinyl chloride, the same is not as fine as it is in CMP-rated cables. 
  2. Irreplaceable: You can use plenum cables as a replacement for riser cables for installation in the riser spaces. However, you can’t use riser ethernet cables as a replacement for plenum cables. 

 

As far as specifications are concerned, like data transfer rates and bandwidth capacities, both riser and plenum ethernet cables share the same properties. For instance, a Cat6 riser cable will have the same data transfer speed and bandwidth capacities as are possessed by the Cat6 plenum. 

Terms to Know when Choosing Plenum Vs Riser Cabling

When shopping for plenum or riser rated cables, here’s a quick rundown of acronyms and other words to be aware of:

Cables with the letters CL, CM, and CMG. Residential-grade or general-purpose cabling is referred to as this. In Riser Or Plenum Environments, It Is Not Suitable For Commercial Use.

CMR Cables are a type of cable. Communications Riser. Approved for use in stairwells.

CMP Cables are a type of cable used to connect Plenum on Communications Approved for use in plenums and risers.

The National Fire Protection Association (NFPA) is a non-profit organization dedicated to preventing fires. The National Electrical Code was produced by this body.

NEC. The National Electrical Code (NEC) is a set of rules (NFPA 70). This guide is intended to establish a standard for electrical safety in residential, commercial, and industrial structures.

Plenum (CMP) Rated Cable VS Riser (CMR) Rated Cable

Plenum-rated cables are utilized in plenum spaces in business and residential buildings. These plenum spaces are found between the ceiling and the floor above it (drop ceiling), and they serve as conduits for heated/cooled or return airflows.

Plenum cables have a higher fire rating and are built with a low-smoke PVC or a fluorinated ethylene polymer fire-retardant plastic jacket (FEP).

In non-plenum regions, riser-rated wires run between floors through cable risers or elevator shafts. In a vertical burn test, these cables must also self-extinguish and prevent the flame from moving up the cable.

Riser cables are not subject to the same fire regulations as plenum cables. As a result, plenum cables can replace riser cables in plenum spaces, whereas riser cables cannot replace plenum cables.

Untitled design 2022 10 06T122618.179

One of the most important components of the computer is the battery, which enables us to take our technology with us and work wherever we wish. Don’t freak out if you encounter the “no battery is detected” problem. Getting one of these error alerts from your laptop doesn’t necessarily imply you need to buy a new laptop or a replacement battery. There are a number of potential fixes for this laptop issue.

How No Battery Present Errors Appear

Battery problem messages can show up as warning warnings in the middle of the screen or as small text alerts along the taskbar at the bottom of the screen close to the battery indicator, depending on your version of Windows.

Here are a few instances of battery-related issues that may occur:

No battery is detected.

Battery #1: Not present.

Consider replacing your battery.

The battery is not detected.

No battery present.

Cause of No Battery Detected Error Messages

Error messages about the laptop battery not being detected are typically brought on by overheating, physical damage to the battery or other laptop hardware, or outdated drivers or other software.

How to Fix Battery Not Detected Errors

While the reason for laptop battery problems may be a mystery, there are a variety of techniques to identify the issue and resolve it.

Connect your laptop. Before you start freaking out, try plugging in the laptop and connecting it to a power source to see if the battery is simply flat. Try turning it on after at least 15 minutes have passed.

Don’t stress about charging your battery too much. When fully charged, the majority of modern batteries contain automatic shutoff features.

Restart your laptop.

Restarting your Windows laptop or desktop computer should be one of the first steps you take when experiencing virtually any issue, including a battery not detected error.

 Give your laptop room to cool.

The battery in your laptop may be overheating if it has been exposed to the sun or if you have been using it while in bed. Try using it on a hard surface after letting it cool off so that the underside can breathe.

To enhance the cooling effect, you might also wish to clean any vents that may be clogged with dust or grime.

Update Windows.

Regardless of whether you are using Windows 7, Windows 8, or Windows 10, it is always crucial to maintain the operating system updated to keep both the hardware and the software functioning properly. Your laptop can be scanned for problems, including the no battery detected one, and fixed with a Windows update.

Click Settings, Update & Security, Troubleshoot, and Power. Run the troubleshooter to check your Windows laptop for problems specifically connected to a missing laptop battery.

Check the battery status.

Click Batteries in the Device Manager, then right-click the laptop battery and choose Properties. Your battery is fine if you see messages showing that your gadget is functioning normally, and the no battery detected bug is probably brought on by something else. Your battery might need to be replaced if you don’t see this message since it may be damaged.

Update the battery’s device drivers.

Launch Device Manager, choose Batteries > Your laptop’s battery name > Driver > Update Driver > Search automatically for new driver software, and then press Finish.

After installing any new drivers, restart your Windows laptop to ensure that they are fully installed and operating correctly.

Removing the battery and restarting your laptop. Perform a complete shutdown, detach all of the cables and power sources, physically remove the battery, press the power button for at least 15 seconds, put the battery back in, re-plug in the charging wire, and then turn on your laptop as usual if it believes there is no battery present. Select Start Windows Normally from the startup prompt if one appears.

Customers cannot remove the batteries from some Windows laptops, such as those in Microsoft’s Surface line of products, and doing so may void your warranty.

Remove the battery and perform a power cycle. Go to Device Manager, choose Batteries, then right-click the names of your battery and the Microsoft AC Adapter. From the menu that appears, choose Uninstall device for each. After completing this, restart your laptop.

Reset the BIOS defaults.

Start your Windows laptop, then go to BIOS Setup. After choosing Restore Defaults, save your work, log out, and restart your laptop as usual.

Depending on the manufacturer and BIOS version, the option may also be known as Setup Defaults or Reload Defaults, but its purpose remains the same.

Use HP Support Assistant.

An application named HP Support Assistant should come pre-installed on any laptop you possess if it was produced by HP. To test the battery, launch HP Support Assistant and choose Troubleshoot. This test may be able to pinpoint precisely why your battery isn’t being identified and provide you tailored solutions.
