Power Supplies, Stack Cables & Rack Ears on Cisco Catalyst
Sellers focus on the switch and forget what came with it. Stacking cables and a dual power supply can change the offer on Cisco Catalyst 9200 and 9300 units, and they are exactly the things that get left in the closet.

Power Supplies
A second power supply gives a switch redundancy, and buyers like that. Keep every fitted unit with its switch.
Many Catalyst models have two power supply bays. A switch with both filled keeps running if one fails. A switch with one filled and one empty works, but it appeals to fewer buyers. Check which bays are filled, and note the model and wattage on each label.
Higher-wattage supplies matter on PoE switches, because they set how much power the switch can deliver to phones and access points. Compare the part number against Cisco’s data sheets for the 9300, 9200 and 9400, because the supply must match the model.
Tip: do not mix supplies between switches. Keep each one in the unit it came from, and write the asset tag on a label.
Stacking Cables
Stack cables join switches into one logical unit. Leave them hanging in the rack and the buyer has to buy new ones.
The 9300 and 9200 families use different stacking systems, and the cables are not interchangeable. The 9200 also needs a small stacking module, which fits at the back on many models. Without it, the switch cannot join a stack. If you removed the module, say so, and keep it with the switch.
Cisco’s 9200 ordering guide lists the stack kits and cables for each model. Photograph the cable ends so a buyer can see the connector type.
Power-Sharing Cables
Some 9300 stacks share power between switches. If you use those cables, keep them.
A separate power-sharing system pools power across a stack, which helps when PoE demand is high. The cables for it are short and easy to miss. If your stack uses them, bag them with the switches.
What to Keep With Each Switch
| Item | Keep it? | What happens if it stays behind |
|---|---|---|
| Second power supply | Yes | Buyer has to source one |
| Stack cables | Yes | A replacement is needed |
| 9200 stack module | Yes | Switch cannot stack |
| Power-sharing cables | Yes, if used | Buyer loses the feature |
| Rack ears | Yes | Switch cannot be mounted properly |
| Blank covers and fans | Yes | Airflow and completeness |
Rack Ears and Covers
Rack ears and blank covers are small, but a missing set is a visible gap. Unscrew the brackets and keep the screws with them.
Rack ears attach with a few screws and come off in seconds. Bag them with the switch. The blank covers that fill empty power supply or module slots protect airflow. Leaving them in place keeps the unit complete.
Spare Parts
Spare supplies, cables and modules can be sold too. Photograph them and list them clearly.
If you have unopened spares, say so and note the part numbers. For how switches are valued, see our Catalyst valuation guide . To clear the whole room, read our comms room guide, and to prepare the configuration, the factory reset guide.
