Moving setup to the XRackPro2 Cabinet

It was time to change my setup to a proper enclosure, due to the noise and heat generated. I’ve decided to move from a StarTech 12U (4POSTRACK12U) open frame to a XRackPro2 12U (XRP2-12U or XR-NRE2-US) Cabinet. This was the cause of the downtime for the site, which has taken longer than I original thought.

Removing the front door enclosure that consist of Ikea BESTÃ… frame 60x20x64, SINDVIK glass door and STUBBARP legs.

The 12U consist of
12) Blank Plate


11) Kenable 24 Port RJ45 CAT6A Coupler
10) QNAP QGD-1600P-4G
9 ) Kenable 24 Port RJ45 CAT6A Coupler
8 ) Kenable 24 Port RJ45 CAT6A Coupler with keystone replace with 14 HDMI, 7 USB, 1 USB-C
7 ) QNAP TS-EC880U R2
6 )
5 ) QNAP TS-1683XU-RP
4 )
3 )
2 ) APC Smart-UPS 1000 UPS

Removing the equipment one by one.

Next is to sort out the cables

Using coupler patch panels are really useful in sorting the heap of Ethernet cables

Redesign the cool airflow for the cabinet, as the inlet is located at the base of the cabinet

Going to be a tight squeeze for installing the cabinet, so it must be flat pack before hand. Power and HDMI are pushed through the bottom cable cutout.

Installing the post for the roof of the cabinet.

Installing the rack frame to stabilise the post.

Hardest part is to installed the roof, there you meet all the post bolts. Must flex the corners to help push the ‘L’ bracket in the inner corner to fully install the roof, the door just slide into place.

Ethernet wiring is fed through the top cable cutout, one by one removed from the patch panel and reinserted.

Cables are out of the way from equipment, makes it easier to put back the servers.

Populate the rack with servers, decided to remove the QNAP TS-EC880U for a QNAP TVS-1271U, and have the power outlet at the bottom. Can’t install anymore servers unless I decided to change the patch panels to a 1U 48 port.

Finishing touch was to route everything back to normal and put the front door and side panels back on.

The QNAP TS-1683XU-RP is the loudest system at 53dB (A), the whining from that server is beyond annoying which is one of the reason for the setup change. There are 3 rear exhaust fans in the XRackPro2, to help pull the hot exhaust from the servers. The fans are not quiet but they are design to help ventilate the cabinet, they make a strong whosh noise than oppose to be whining. The fan used:

US Toyo fan USTF120382302T
Size: 120 x 38mm
Acoustical Noise: 30dB (A)
Airflow: 76CFM
RPM: 1950
Bearing: Dual Shielded Ball Bearing

This cabinet is not a silent or quiet cabinet, it has sound proofing that helps dampen the higher pitch equipment. It helped reduce the whining noise, and turning on all the servers helped muffled the pitch much better than the open frame. The front glass was necessary to see all the equipment quickly and to utilise wireless peripheral such as keyboard, zwave etc. The cabinet itself is made from 1mm steel, and it has an built in air filter system. One big filter 15″ 3/4 x 26″ located at the bottom of the cabinet where you can slide and replace the filter with ease. One smaller filter 4″ 1/2 x 15″ at the front of the cabinet, where it is held by two Velcro point.

Overall I’m happy with the build quality, just that getting replacement parts to the UK is difficult where the manufacture (XRackPro) is based in the US and they do not deliver to the UK, so you must rely on a reseller.

    I have been using an XrackPro2 12U myself to hold two Synology Rack NAS + Dell r720 Server.

    It does the job but I wish the sound dampening was better.

    Question about the PVC pipes you have on the floor for Air – are they bringing cool air into that tight area of space, or, removing the hot air?

    Friend is using my old RS3412RPxs+ but is having thermal issues, and I found your old blog post about changing the CPU.

      Hi Tom, the ducting is used to bring cool air, directly underneath the rack enclosure of the inlet vent. Due to the bends and travel of the piping, I’ve used a centrifugal fan to assist pulling the air from the next room. The room has a basic fan extracting the hot air out but it needs to be overhauled due to the enclosure outputting more hot air that it can extract. Eventually when I have time I will make a custom ducting for the rear fan, to make the room cooler. Though the enclosure is very good at managing the temperature inside, and blocking the hot air getting back into the system.

      For your reference with the XRackPro with everything on, the inside at the front of the servers the temperature range from 27-31 (29 avg.)
      Previously in the open rack the temperature was 29-37 (34 avg), and the hot air was getting trapped at the rear or the server causing additional heating to build up.

      Oddly with the lower temperature for the XRackPro, the temperature for the System, CPU and HDD are very similar to the old setup. But that was with the backup server turned off, but I still believe the enclosure is helping isolate the heat away from the system.

      If your friend is having issue I would suggest that you extract the hot air away from the system to outside, if not try and bring cooler air from the next room but you need to use AirCon to manage the ambient room temperature as the heat needs to go somewhere.

        thank you for explaining your duct setup… very nicely done.

        I have been looking to replace the very-old xRackPro2 Toyo rear fans; and have been learning a great deal about fans.

        Are you still using the stock Toyo rear fans; or have you found something better to replace them with?

        • poyu says:

          Hi Tom, I have yet to tweak the fans on the cabinet, due to it working perfectly fine. If I ever get to change the fans I will let you know, but for now I just wait till they fail. If you ever find a good alternative to Toyo just us know, as they are expensive to source. Though finding the right fan will take some time cause you need the correct static pressure, noise, bearing type and size to match with your use case and environment.

          • Tom says:

            indeed, it is interesting (and somewhat frustrating) learning about quality fans – static pressure, harmonics of the sound, RPM; etc.

            How Fan-A can be “louder” than Fan-B; but its harmonics are much less annoying. (and Harmonics are not something that can really be measured)

            Have learned that Noctua are not as outstanding as I had assumed.

          • poyu says:

            Yeah Noctua fans do not provide the necessary static pressure, but it very quiet. It’s not design to be a work horse, I would suggest finding AVC hydraulic bearing fans but there are loads of fake. I happened to bought several bunch of AVC hydraulic but once I got it, the sticker was fake and the housing was a Delta. This were imported from China, use eBay not AliExpress for buyers protection.
