Engineered for professional AV environments, the Middle Atlantic ERK Series 35RU AV Floor Standing Rack offers a robust, economical solution for housing, organizing, and protecting critical equipment. This 35RU, 20-inch-deep cabinet is designed as a standalone solution with solid sides, delivering dependable protection while maintaining flexibility for growth. The ERK Series is purpose-built for reliability in control rooms, broadcast suites, studios, and data centers, and it can be ganged with other ERK units to form partitioned multi-bay installations that simplify thermal management, cable routing, and security. With seismically certified performance when paired with ERK-Z4 brackets, this cabinet provides peace of mind in environments where equipment uptime and safety are paramount.

  • Economical standalone rack with solid sides that delivers dependable protection for your AV and IT gear, while remaining budget-conscious. The ERK Series is designed for scalable growth: start with a single cabinet and, when needed, gang multiple units to form partitioned, multi-bay installations that help manage heat, organize cables, and improve serviceability. The fully welded frame and solid sides reinforce structural integrity, guarding against everyday wear and accidental bumps in busy environments, while maintaining a clean, professional appearance that fits any installation.
  • Seismic-certified protection for critical equipment when installed with ERK-Z4 brackets. This certification adds a vital layer of safety in regions with seismic activity or where equipment downtime carries a high cost. The combination of rugged chassis and compatible seismic hardware helps preserve equipment integrity during movement, reducing the risk of damage to servers, processors, routers, patch panels, and other essential AV components. The ERK-Z4 bracket system enables secure anchoring and integrity within partitioned bays, supporting safer, longer-lasting deployments.
  • Generous capacity and depth for versatile gear layouts. At 35RU and 20 inches deep, the ERK 35RU cabinet accommodates a wide range of standard 19-inch equipment while leaving room for cabling, power distribution, and future expansion. The deep cabinet profile is ideal for deeper multi-function units, multiple patch panels, power distribution units, and stacked components, while the 35RU height provides ample mounting space for mid- to large-scale configurations. This combination strikes a balance between footprint efficiency and practical mounting real estate, making it suitable for mid-sized control rooms, post-production suites, and classroom AV racks.
  • Partitioned multi-bay capability for optimized thermal management. The ERK Series is designed to be ganged to form partitioned bays, enabling you to group equipment by heat generation, function, or service access. By configuring bays to address thermal zones, you can manage airflow more effectively, simplify cable management, and improve maintenance workflows. The modular approach allows you to scale from a single cabinet to a multi-bay installation without sacrificing access or serviceability, ensuring critical gear operates within its optimal temperature range.
  • Flexible, durable installation options for professional environments. The ERK 35RU floor-standing cabinet serves as a standalone solution for immediate deployment or as part of a wider ERK system for larger installations. Its sturdy welded construction, combined with solid sides, makes it a reliable home for servers, AV processing gear, and surveillance components while maintaining a streamlined, aesthetically pleasing appearance in control rooms, studios, and conference facilities. The cabinet is engineered for long-term performance in demanding environments and supports straightforward service access, cable management, and equipment upgrades as your system evolves.

how to install Middle Atlantic ERK Series 35RU AV Floor Standing Rack

  • Plan your layout: evaluate the space, weight load, ventilation, and door clearances. Confirm the intended number of bays if you plan to gang multiple ERK units for a multi-bay installation, ensuring alignment with your workflow and service access needs.
  • Prepare the space: verify a level surface and adequate room for front and rear access. Ensure proximity to power sources, network connectivity, and any required climate control to maintain optimal operating conditions for mounted equipment.
  • Assemble or position the cabinet: if you’re using a single ERK 35RU cabinet, place it in the designated area and verify level. For multi-bay configurations, align adjacent cabinets precisely before securing any interconnecting components. Use appropriate floor anchors if required by local building codes and security standards.
  • Install seismic provisions if needed: if the installation requires seismic protection, install ERK-Z4 brackets according to the manufacturer’s instructions. This step helps realize the designed seismic certification and ensures secure mounting for the cabinet and its contents.
  • Mount equipment and manage cabling: install 19-inch rack-mount equipment within the 35U space, using standard rack rails and hardware. Route cables neatly to minimize obstruction and maximize airflow, leaving adequate space for maintenance and future upgrades. After mounting, recheck level and stability, then test power and connectivity to confirm all devices operate as intended.
  • Finalize and secure: close access panels, verify that assembly is stable, and confirm that any modular or ganged bays are properly interlocked or bridged as required. Document the configuration for maintenance and future scaling, and ensure compliance with facility safety and electrical standards.

Good book minus Containers chapter.
Format: Paperback
Great book with useful information. However, I gave it 4 starts due to the "Containers" chapter. Very poorly written chapter. In fact, if you get this book, just ignore the container chapter as it will only waste your time and can be better spent using other sources.

Good book that will help with your RHCSA, But...
Format: Kindle
...watch out for typos and problems with some of the explanations in some parts of the book. I bought this book (kindle version) and used it to pass the RHCSA. The book is clearly tailored for the RHCSA and to be fair does live up to that reputation. There are a lot of exercises and examples that clearly outline what the author is trying to convey. Examples are clear to understand and if you do the exercises yourself, then you are well on your way to passing the RHCSA. However, there are a lot of typos big and small and I did send them to the author with the assumption that it would benefit others with the corrections (especially the kindle version). The author was responsive at the beginning acknowledging the errors. I did not check whether they have been fixed or not. I just went through the content after making note of the typos and with the understanding that he would fix it. The topics are well covered and explained. Three topics that could have been better covered are SELinux, AutoFS and Containers. The explanation uses excessive word-o-logy that leaves somebody new to SELinux with tons of confusion and more questions. I used youtube resources to prep myself on the how and why (Ed Walsh on a youtube channel clearly explains the need for SELinux - I have not seen a better explanation than Ed's anywhere else). The author's coverage of AutoFS is again excessive word-o-logy that is a confusing mess. The examples are fine, but the explanation uses confusing rhetoric that can leave you messed up with NFS and AutoFS setup. I read explanations on direct and indirect mappings and watched a couple of youtube videos before I understood what the author was trying to convey. I pointed out both of these to the author. The container chapter is missing explanations or examples that the reader is well advised to take note. DIY labs 22-3 and 22-4 relate to rootless containers and therefore has to be launched as a regular user. Both labs require that you launch rootless, persistent data containers with folders under /. However, the author does not mention in any of his examples that this type of container requires you to "chown" the folders under root to belong to the user. If you launch a rootless container with this setup as a regular user without "chown"ing, (even with full DAC permissions for everybody) then SELinux does not want to apply the correct context type (container_t to the shared folder). For both these DIYs, if you make a folder anywhere other than areas that a regular user can write or has access, then you will need to "chown" it to the user before launching the rootless container, otherwise this has to be launched as a root container not rootless. I pointed this out to the author. I did not hear from him. Further, container questions (20,21,22) in mock exam #3 has user60 with a NFS mounted home folder. The questions relate to launching rootless containers as user60 with a NFS mounted home folder. SELinux barfs when it encounters the home folder with a type context as "nfs_t" for user60. It suggests workarounds that did not work for me. I googled it and the latest versions of podman seem to have some fix for the errors associated with a home folder on a NFS server. I tried to research this issue further but had an exam scheduled within days. Therefore, I requested the author for clarification/help. Here again, I did not hear from him. Luckily, I did not have to work on any such scenarios on the real test. Still, the book is a good reference to the topics on the test and is pretty useful. Although I had to refer to other resources for some chapters, the examples and mock exams are very good.

Excellent Study Bundle! Don't Let Negative Reviews Fool You!
Format: Paperback
I received the four books in a box, and they arrived brand new and exactly as described. These books are truly great for learning and easy to follow. I was almost discouraged from ordering because of some of the negative reviews, but I'm so glad I decided to see for myself and ordered this bundle deal. While the internal pictures and screenshots are not high definition or in color, they are perfectly easy to view and follow along. The author does an excellent job of guiding you, telling you exactly what to look at within the picture to follow along and understand the concepts. All the screenshots are spot-on and very readable. This is my first set of A+ books from Sybex, and I have the two main study books, the review guide, and the practice questions book. Wow! What else can I ask for? I used to rely on the big books with the golden covers, but they didn't have the latest editions. Too bad for them—this is a huge gain for me! Thank you, Sybex and Authors!
