The Anatomy of a Flawless Delivery


107 Cisco switches and routers. To most, it’s just hardware. To us, it was a mission.

When the client called and said they needed the entire batch deployed and ready to ship in just 3 days? Most teams would have panicked. For the crew at Go, it was just another day. We pulled up our sleeves, fueled up on caffeine, and got to work.

Here is exactly what it took to get this massive batch out the door and into production:

• 3 Relentless Engineers: They ran diagnostics, pushed firmware, and stress-tested every single port until the hardware practically begged for mercy. If it wasn't performing better than the day it left the factory, it didn't pass.
• 2 Obsessive Sprayers: Armed with a perfectionist streak and a zero-tolerance policy for scuffs. They refused to accept anything less than a flawless, showroom-ready finish.
• 2 Refurb Magicians: The packing crew who treated cardboard and foam like fine art. Every single unit was wrapped, nestled, and secured like it was headed straight to royalty.


190 hours of collective graft, grit, and obsessive attention to detail.
All for one extremely satisfied customer.


We don’t just refurbish enterprise hardware—we romance the routers. Because your network deserves nothing less than perfection.

Ready for the royal treatment?

Whether you need 10 units or 100, we put the exact same sweat and soul into every build. Feel free to drop me a message or email: david@gocomsys.com to get your next batch of flawless, battle-tested hardware.

There was a time when just about every major network across the land had a Cisco GSR12000 sitting proudly at its core.


For years, we recycled them without a second thought. But now that everyone else seems to have done the same, just try finding one when you actually need it.

Suddenly, they’re not quite so common anymore…

We’ve had to jump through more than a few hoops to get these old classics back into fighting shape—replacing memory, upgrading where possible, and carrying out full software restorations. Why? Because Cisco (and, if I’m honest, me too) would probably say you really shouldn’t still have a GSR12000 in your network.

But some people do. And I doubt there’s anyone left at Cisco who even remembers what these beasts are. We do.

So if you’re ever looking for a GSR12000 that actually works properly, don’t expect it to be cheap just because it’s 20+ years old. Classics rarely are.

Ooh!


A couple of Arista switches landed with us last week, and we’re definitely starting to see more 400G kit being decommissioned as customers make the jump to 800G.

Progress waits for no one.

These switches originally carried list prices north of $150,000 — refurbished, they’re a very different conversation (and one your finance team won’t flinch at).

We’ve been refurbishing Arista for around 12 years now. With roots in Cisco’s engineering talent, the build quality is absolutely top-notch, and at the high-speed end of the market they’re widely regarded as leaders in low-latency switching.

Getting our heads around the rack accessories? Let’s just say it was a little more “hands-on” than expected. Arista favours self-locking rails, so we did what we always do — stocked up properly on rail kits and rack ears so nothing slows customers down.

We’re seeing strong growth in customers using refurbished Arista as a sensible way in — spares, pilots, or first deployments. And no, I don’t think we’re hurting Arista’s new sales. Quite the opposite: once customers get a taste, many go all-in and upgrade to new on the next refresh.

Need pricing or availability on refurbished Arista? Get in touch.

250+ fully refurbished Cisco switches and routers out the door this week.


Behind that:
2 sprayers working late
3 refurb engineers packing and preparing
480 hours of proper graft and attention to detail

It’s easy to say “refurbished”… but there’s a lot that goes into getting equipment back to a standard we’re happy to put our name to.

We don’t just refurbish — we take our time with it.

Let’s just say these switches and routers leave here looking and feeling better than they have in years.

We don’t just refurbish—we romance the routers and seduce the switches

Ever wondered why some great products just don’t move?
Even when the price looks too good?
This was one of those moments.


Around 18 months ago, we worked with a US partner on a large de-install project in London — a significant number of Cisco C9400s coming out of one of the world’s biggest search engine companies.

At first, I thought they’d fly out the door. After all, this is the platform that followed the legendary Catalyst 4500.
But they didn’t.

In that time, I’ve only moved a couple of chassis, a few fan trays, and the odd supervisor or line card. It didn’t quite add up.

So I dug a bit deeper.

Turns out Cisco has refreshed this platform unusually quickly — multiple generations of supervisors in a relatively short space of time. Add to that previously attached support contracts complicating future coverage, and suddenly the market hesitation starts to make sense.

Fast forward to now — and we’ve just had an enquiry for 20+ systems… almost identical to what we have sitting in stock.

Here’s the interesting part:
Used Cisco pricing isn’t driven by spec — it’s driven by supply and demand. So despite the demand, the price still looks artificially low.
Would I increase the price because of a strong enquiry? No.

Three simple reasons:
1. There’s no guarantee the deal lands
2. Two-tier pricing isn’t good for reputation — word gets around
3. It’s just not how we do business

I’d rather move the stock, return value to us and our partners, and keep things consistent.

So if you’re looking for lab kit, support spares, or a cost-effective step up from a Catalyst 4500 into the 9400 space — now might be a good time - feel free to drop me a message or email: david@gocomsys.com

Sometimes the opportunity isn’t obvious… until it is.

If you’re going to penny-pinch on spares, please make sure it’s not power supplies.


They’re far more reliable than they used to be. But at their core, they’re still built on electromagnetic induction — a 19th-century principle doing a 21st-century job.

Solid? Yes.
Proven? Absolutely.
Immune to failure? Not a chance.

And when a PSU goes, it rarely does so quietly — or conveniently.

So do yourself a favour: hold a couple on the shelf. Because when one fails five minutes before a critical call, a maintenance window, or the end of the working day, you don’t want your resilience plan to be “hope.”

Power supply redundancy isn’t overkill. It’s cheap insurance.

Don't wait for a failure to buy your insurance. Drop me a message today and let's get your shelves stocked.

Happy Wednesday, everyone!


For me, packaging is half the battle when it comes to selling used network equipment.


Back in the day, sending kit out wrapped in bubble wrap and foam beads was “normal” — and I hated it. Even then, when networks weren’t quite the board-level priority they are today, it just didn’t feel right.


So we did something about it. We invested heavily in proper packaging, absorbed the setup costs, and redesigned it over the years until we got it right. Painful at the time… but absolutely worth it.


Fast forward to today, and it matters more than ever. If you’re justifying the decision to buy used network infrastructure, the last thing you want is that sinking feeling when the box arrives.


When you buy used (properly refurbished) network equipment from us, it arrives looking like it came straight from an OEM. That’s always been the goal — and it’s how we’ve been reassuring customers for years.

Is buying refurbished IT equipment a smart move or a ticking time bomb? 💣


From my 30 years’ experience refurbishing networks and servers, this is never a simple yes-or-no decision. Much like the image suggests, networks are built from individual, well-understood components—and what matters is how solid those
building blocks are, not whether they’re brand new.

The real considerations come down to a few key factors:
• ⚖️ Risk vs. Cost: Balancing the budget against operational downtime.
• ⏳ Lifecycle & Support: Knowing when a component's support status actually matters.
• ⚙️ Failure Rates: Identifying which parts are prone to wear and which are practically indestructible.

Refurbished and used equipment plays a vital role in the IT ecosystem when deployed strategically. There are clear lines, of course: I wouldn’t deploy an unsupported firewall or outdated Wi-Fi access points. However, servers, memory, switches, and routers are proven, stable platforms that can perform reliably for years.

What about power consumption? 🔌 It's a concern that is frequently overstated. Only at a massive, enterprise data-centre scale does power efficiency become a dealbreaker. In most standard business environments, the massive upfront savings of refurbished hardware would take many years to be offset by the minor efficiency gains of buying brand new.

Like building with LEGO, it isn’t about whether the pieces are brand new out of a box—it’s about whether they still lock perfectly into your design.

It’s not cut and dried, but it can always be calculated.
