Removing and replacing a drive filler
Refer to the service procedure to remove a drive slot filler in an IBM Elastic Storage System 3500
enclosure and replace it with a new one from stock.
The following steps are the high-level flow of the procedure:
1. Remove the drive filler.
2. Replace with the drive filler replacement part.
Note: If you encounter an error or an unexpected result, contact the next-level support.
Note: Drive slot fillers are passive components that regulate airflow through the enclosure.
No tools are required to complete this task. Do not remove or loosen any screws.
When you replace this part, you must follow recommended procedures for handling
electrostatic discharge (ESD) sensitive devices.
IBM Elastic Storage System 3500 enclosure supports up to 24 U.2 dual ported NVMe SSDs and the drive
slots are numbered from 1 through 24 as shown in Figure 8 on page 6. All 24 drive bays must be filled
with drive carrier assemblies, each containing either a drive, or drive filler (blank), to ensure proper airflow
and system cooling.
Note: Every drive slot of an operational control enclosure must contain either a drive or a drive slot filler.
A drive slot must not be left empty for more than 10 minutes during servicing. Ensure that you have
read and understood the removal and replacement instructions and have the replacement part that is
unpacked before you remove the existing drive slot filler.

A drive carrier assembly is composed of the drive or drive blank and a drive carrier, and are used to
provide for controlled insertion into, and extraction from, the storage enclosure. Drive carrier assemblies
are installed from the front of the enclosure, which simplifies service access. Closing the drive carrier
handle ensures complete seating of the connectors.
