C2960S-STACK
Cisco C2960S-STACK Catalyst 2960S Series FlexStack Module
Cisco
$269.00
A Single Flexstack connection provides a full duplex 10gbps link between two members. Each Cisco Catalyst 2960-S member facilitates two Flexstack connections, offering 20gbps of stack bandwidth per member. Up to four switches can form a single logical switch through stacking. Multiple physical switches operate as a unified entity, known as a logical switch. Using a hop-by-hop method, Ethernet packets get transferred across the stack, traversing from one member to another via the Flexstack links.

Good unit overall. Ports are exactly what we needed and first boot went fine, just took longer than I expected to get everything updated. Once done, no issues in normal use.

BiDi is a lifesaver when you're out of fiber pairs. Using these in a campus backbone—got 100G over a single strand of OM4. 100m reach is accurate. Runs a bit warm but that's normal for BiDi. Cisco tax is real but worth it for the convenience.

Installed it in an ISR 4000 and it came up right away. Setup was pretty easy, just needed a reload and the interfaces showed as expected. Been using one copper uplink and one SFP port daily for about three weeks, no weird drops so far. Build quality feels solid like most Cisco gear.

Standard GLC-LH-SMD won't survive in some places. These RGD versions will. Used them in oil field gear—no failures in two years. DOM still works, range is solid. Cisco rugged optics are no joke.

Lifesaver when you need 10G over existing copper. 30-meter limit is honest—tested it at 28 meters with clean signal. Uses more power than fiber optics but sometimes you don't have a choice. Cisco quality.

Rock-solid SX optics. The D version has DOM, which is actually useful for checking fiber health. No compatibility headaches, no weird errors. If you need 1G multimode, this is the go-to.

If your gear lives in an uncontrolled cabinet or industrial site, grab these. The rugged rating actually means something. 550m on multimode, DOM works, and they don't flake out when temps go crazy.

Standard GLC-LH-SMD won't cut it in some places. These RGD versions will. Same DOM features, same LX/LH reach, but they actually survive in the real world. Used them in traffic cabinets—zero failures.

You can't go wrong with these. 10km on single-mode, no sweat. The DOM actually works, which is nice for troubleshooting fiber runs. Standard Cisco quality—plug it in and forget about it.

These NIM-ES2-8s are handy for consolidating gear. No need for a separate switch—just plug this into your router. VLANs, STP, basic switching all work. Runs cool, no fan noise. Great for small branches.
