The Project That Started Innocently Enough
Back in early 2024, our operations manager dropped a bombshell: we needed to upgrade our core network switches. The current setup—aging Cisco gear stacked on a couple of open shelves in the server closet—was becoming a reliability risk. The decision to upgrade was easy. The delivery method? That's where I got pulled in.
I’m the office administrator. Normally, I handle supply orders, coffee machine repairs, and vendor invoices. But when the ops team got overwhelmed, the rack procurement fell on my desk. “Just get us a standard 24U rack,” they said. “Something simple.” Famous last words.
The First Shock: Rittal Isn't Just a Cabinet
When I started Googling “Rittal 24U rack,” I expected basic server cabinet listings. Instead, I found myself drowning in options: N93, N, TS, TX—all different series. I didn't even know what N93 meant initially. (Turns out, it's a modular cooling and enclosure system line. Noted.)
I went back and forth between the N93 series and a standard TS rack for maybe two weeks. The TS rack had a lower upfront cost and was in stock at a major distributor. But the N93 offered integrated climate control and busbar options that our electrician said would simplify the install. Ultimately, I chose the N93 because our tech team was worried about heat buildup in that tight closet, and retrofitting cooling later would be more expensive. Or so I hoped.
The Busbar Dilemma
Then came the Rittal busbar. Our network switches needed reliable power distribution, and the electrician recommended a busbar system instead of individual power strips. “Better load balancing,” he said. “And cleaner for future expansion.”
I started pricing out the Rittal busbar kits. The component list was longer than I expected: trunking, taps, adapter modules, end caps. Not cheap. Not complicated to order, but expensive. I sat at my desk comparing the busbar cost against a standard PDU (power distribution unit) setup. The busbar was about 40% more. But the electrician insisted that the install time would be halved, and the reliability was better for 24/7 operation.
Still, that $2,400 price difference made me hesitate. “I'm not 100% sure,” I told my boss, “but the busbar seems like future-proofing. The PDU might need replacing in two years.” Take that with a grain of salt—I'm no electrical engineer. But the decision felt right after talking to three different vendors.
The Install Nightmare That Wasn't
Delivery arrived on schedule—a pleasant surprise. The rack was heavy, but the packaging was solid. Then came the install. Our electrician, a guy who's been doing this for 20 years, walked in, looked at the N93, and said: “Haven't worked with one of these before.” My heart sank.
He spent the first hour reading the manual (a good sign, I guess). But the install took a full day instead of the planned half-day because the busbar mounting required adjustments to the rack's internal frame. The cables had to be routed differently than the standard TS rack. We had to call Rittal tech support twice (to be fair, they were helpful and patient).
The installer's original estimate was $800. The actual bill? $1,100—because of the extra time. So that busbar savings on install time I'd been promised? Not in my case.
Post-Installation Doubt… Then Relief
After the install, I kept second-guessing. What if the standard TS rack with a PDU would have been fine? The extra cost was eating at me. Had I over-engineered for a simple switch upgrade? The two weeks after go-live were stressful. I'd walk by the server closet and listen for fan noise. (Internal joke: admin with unnecessary anxiety over enclosure specs.)
Then, three weeks in, we had a minor power flicker. The building's UPS kicked in, the switches stayed up, and the busbar system handled the load without a hiccup. Our network team reported zero issues. Exactly what we needed.
So glad I went with the busbar. Almost cheaped out and regretted it. Dodged a bullet, even if the install wasn't perfect.
What I Learned (The Hard Way)
Looking back, here's what I'd tell any admin facing a similar rack decision:
- Get your tech team's input early. I assumed an enclosure was just a box. It's not. The series choice (N93 vs. TS) affects cabling, cooling, and future expansion.
- Factor in installation time. The cost of the rack is only half the equation. If your electrician isn't familiar with Rittal's system, budget for extra labor.
- Busbars aren't cheap, but they're future-proof. If you're upgrading switches anyway, the busbar investment pays off when you add more power-hungry gear later.
- Trust but verify vendor claims. I assumed the busbar would save install time. It didn't—in our case. But the operational reliability is worth it.
Would I pick the Rittal N93 again? Yes. But I'd be more realistic about the timeline and budget. The fundamentals of racking—protection, cooling, power distribution—haven't changed. But the execution? It's evolved a lot from 2020. That old shelf setup is long gone. And I'm glad we upgraded when we did.
