About this blank filler
A blank filler is a cover that sits in an empty drive bay, power supply bay, card slot or port on a server, switch or computer. It guides cooling air across the components that need it instead of letting it escape through the opening, and it blocks dust and fingers. If a blank is missing after a part is taken out, temperatures can rise, fans may speed up, and the system can flag an open bay.
Is this the right part?
Look for the part number moulded into the blank or printed on its label. Before fitting, check your equipment's model and generation, and confirm the bay or slot type, since drive, power supply and card blanks differ. The manufacturer's part number for this listing is 03X3866.
Not sure? Send us the number from the label, or your machine's serial number, and we will confirm the match before you order.
