3.5 Chassis Components
Front Bezel
If your system has an optional bezel attached to the front of the chassis, you will need to
remove it to gain access to the drive bays.
1. Unlock the front of the chassis and then press the release knob.
2. Carefully remove the bezel with both hands. A filter located within the bezel can be
removed for replacement/cleaning.
It is recommended that you keep a maintenance log to list filter cleaning/replacement dates,
since its condition affects the airflow throughout the whole system.
Hard Drives
The SC218U chassis has twenty-four hot-swappable 2.5" drive bays. The hard drives are
mounted in drive carriers to simplify their installation and removal from the chassis. System
power may remain on when removing carriers with drives installed. These carriers also help
promote proper airflow for the drive bays. For this reason, even empty carriers without drives
installed must remain in the chassis.
Drive configuration: All drives support SAS3, and drives HDD20-23 also support NVMe. They
are connected to four NVMe ports from additional expansion cards.
Removing Hard Drive Carrier from the Chassis
1. Press the release button on the drive carrier. This extends the drive carrier handle.
2. Use the handle to pull the drive out of the chassis.
3. Remove the dummy drive from the carrier (Figure 3-10).
