Application Scenarios
Use C9400-PWR-BLANK when a Catalyst 9400 chassis has an unused power supply bay and the order needs the Cisco-listed cover for that bay position.
Keep this SKU available when power supply replacement work may leave a bay without a PSU and the site needs a clean cover item for the maintenance plan.
When the final power design uses fewer power modules than the chassis can physically accept, add the blank cover line separately from the active PSU line items.

- In a C9400-PWR-BLANK vs C9400-S-BLANK comparison, the difference is the chassis opening: C9400-PWR-BLANK is for a power supply bay, while C9400-S-BLANK is the Catalyst 9400 slot blank cover.
- The C9400-PWR-BLANK difference from C9400-PWR-3200AC is the hardware role; the blank cover protects an unused bay, while C9400-PWR-3200AC is an active 3200W AC power supply module.
- For buyers comparing C9400-PWR-BLANK vs C9400-S-BLANK vs C9400-PWR-3200AC, the key order check is whether the open position is a power bay, a module slot, or a powered PSU requirement.
Selection Guide
1. Choose it for an empty power supply bay
Select C9400-PWR-BLANK when the Catalyst 9400 chassis plan leaves a power supply bay unused and the bay still needs the Cisco-listed blank cover.
2. Do not substitute the slot blank cover
Use C9400-S-BLANK only for Catalyst 9400 slot blank cover needs; it should not replace the power supply bay cover in the BOM.
3. Keep PSU modules as separate line items
Quote C9400-PWR-2100AC, C9400-PWR-3200AC, C9400-PWR-3200ACT, or C9400-PWR-3200DC when the requirement is an active power supply module rather than a bay cover.
4. Confirm installed PSU count before shipping
Check the chassis model, installed power supplies, and unused bay positions before approving the blank cover quantity.
