3.4 Chassis Components
Hard Drives
A total of 16 hard drives may be housed in the SC745BTS-R1K28BP2 chassis (eight 3.5"
drives in the chassis and eight 2.5" drives in the optional mobile rack unit, which replaces two
of the 5.25" bays). Two NVMe drives are supported with optional cables (CBL-SAST-0818).
The drive IDs are preconfigured as 0 through 7 in order from bottom to top (or from left to right
depending if rackmounted). A bezel covers the drive area but does not need to be removed
to access the drives; simply swing open the bezel. If you wish to remove the bezel piece,
push on the three tabs on the inside of the left lip of the front chassis cover. Then slightly
swing out the same (left) side of the cover - about ½ inch only. Remove by pushing on the
open side of the cover to remove it from the chassis (do not try to swing or pull it straight
out after opening the left side).
The drives are mounted in drive carriers to simplify their installation and removal from the
chassis. These drives are hot-swappable, meaning they can be removed and installed without
powering down the system. The carriers also work to promote proper airflow for the system.
For this reason, even carriers without drives must remain in the server.
Installing/Removing Hard Drives
1.
To remove a carrier, first open the front bezel.
2. Push the release button located beside the drive LEDs.
3. Swing the handle fully out and then use it to pull the unit straight out.
Mounting a Hard Drive in a Drive Carrier
1. Insert the drive into the carrier with the printed circuit board side facing down so that the
mounting holes align with those in the carrier.
2. Secure the drive to the carrier with four screws.
