Can DAC Cables Be Used as Stacking Cables?

Switch stacking is not unusual in today’s network switch world. It becomes a quick way to increase capacity and flexibility by “stacking” stackable switches and operating them as a single unit. Some stackable switches can be stacked via DAC cables while some must be connected via stacking cables as vendors claim. What exactly are stacking cables here?

Are they the same as DAC cables? Find answers in the article below.


What Are Stacking Cables?

Stacking cables, some also called stack cables, are the cables used for multiple stackable switches to be physically connected together as the name suggests. Which cables to choose depends on the stacking types of the switches, how far your switches are, your budget and other elements. Following list the common stacking cables and the alternatives for switch stacking.


DAC/AOC Cables

AOC and Direct Attach Copper cable (DAC cable) are the commonly used connectivity solutions for data transmission by connecting network switches to switches, routers, or servers via the data ports. For some certain stackable switches, DACs and AOCs are not only applicable for transferring data but also used as the stacking cables. DAC and AOC are one of the most cost effective and simple solution to stacking. And DAC cables are more widely used by significantly reducing more costs over the AOCs of the same length.

When to Use DAC/AOC Cables for Stacking?

When the stackable switch supports front-panel stacking (FPS), which represents stacking via the Ethernet ports on the front panel of the switch, cables for data transmission can be used as stack cables. This makes DAC cables or AOC cables applicable.

The stack cable is connected to the Ethernet port on the front panel of one switch, and the opposite end of the cable is plugged to the stacking ports of the row on the opposite directions of another switch.?
