Articles | Nettech

Nettech has sold and supported enterprise network hardware since 2001. The engineering work is the other half of that business: design the refresh, stage the boxes, recover a locked chassis, and keep the cutover from turning into an outage. This page is for Front Range operators who need Colorado network engineering tied to real inventory — not a ticket queue in another time zone.

Call 1-800-745-0120 or request a quote. No street on this site; we are a service-area shop covering Denver, Boulder, Fort Collins, Loveland, Longmont, and the I-25 corridor.

What “network engineering” means here

It is not a blog category. It is the work that happens around the part numbers on a purchase order.

Design and bill of materials. Access, distribution, data center, and WAN. Catalyst, Nexus, Aruba, Juniper — specified by manufacturer part number, not a house SKU.
Staging and configuration. Image, license, VLAN, uplink, and management before the window. Less guessing on the raised floor.
Cutover and rollback. A written plan, a spare in the box, and a path back if the new stack misbehaves.
Password and ROM monitor recovery. Locked Cisco and other enterprise chassis recovered so the refresh is not blocked by a forgotten enable secret. Use the password recovery finder for the procedure; call when you need the work done on a box you just bought — or one already in the rack.
Break-fix and emergency support. Failed supervisor, dead power supply, optics that will not link. Hardware on the shelf plus engineers who have seen that failure before.
Asset recovery. Take-out of surplus Cisco and enterprise gear with certified handling, so the refresh is not a pile of unmarked chassis in a cage.

Front Range, not a national 800-line with no bench

Search “network engineer Denver” or “Cisco consultant Colorado” and you get MSPs who do not stock a C9300, and liquidators who will not stay on the phone through a boot loop. Nettech sits in the middle on purpose: tested hardware ready to ship from Colorado, and engineering on the same ticket.

Service area — Denver, Aurora, Lakewood, Boulder, Fort Collins, Loveland, Longmont, Littleton, Highlands Ranch, Greenwood Village / DTC. Same-day or overnight along I-25 for in-stock gear. Remote engineering for everyone else. We do not publish a walk-in address.

Hardware the engineers actually put in the rack

Every public line uses a true manufacturer part number. If the chip is empty, we leave it empty. Examples currently associated with live inventory and recovery work:

Campus and access: C9300-48P-A, WS-C3850-48P-S
Optics: GLC-T, SFP-10G-SR
Aruba / HPE when that is the campus standard: JL727A (quote the manufacturer token; we will not invent a SKU)

Condition on the shop is only refurbished, new, or new in open box. Browse Denver / Front Range hardware or the full shop. If the P/N is not priced, it is quote-only — that is honest, not a tease.

How a typical engagement runs

You send the P/Ns, the software train, and the window. Or you call and we pull it out of you.
Nettech confirms stock or sources the exact manufacturer tokens. No “compatible” module sold as Cisco.
Engineering writes the staging notes: image, stack, uplink, management VRF, licensing.
Boxes ship or hand off. Cutover support is on the same thread as the invoice.
If a chassis is locked, recovery is scheduled before the window, not during it.

That is the product. Not a retainer slide deck.

Who this is for

Colorado MSPs and internal IT that need Cisco or Aruba filled this week, configured, and warrantied.
Colo and carrier NOCs along I-25 that already know the P/N and need a shop that will not ghost them after the RMA.
Shops replacing end-of-support Catalyst 3850 / 3750-X plants with 9300-class access without a six-month VAR circus.

Start with a P/N or a symptom

Email info@nettechcorp.net, use contact, or call 1-800-745-0120. Put the manufacturer part number in the subject if you have it. If you do not, put the symptom: no console, boot loop, optics down, stack split.
