Drive Bay Installation

SAS/SATA Hard Drives

A total of 16 SAS or SATA drives may be housed in the SC745 chassis (eight 3.5"
drives in the chassis and eight 2.5" drives in the enclosure unit). The drive IDs
are preconfigured as 0 through 7 in order from bottom to top (or from left to right
depending on their orientation). 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.
Caution: Regardless of how many drives are installed, all drive carriers must remain
in the drive bays to promote proper airflow.
Caution: Enterprise level hard disk drives are recommended for use in Supermicro
chassis and servers. For information on recommended HDDs, visit the Supermicro
Web site at http://www.supermicro.com/products/nfo/storage.cfm
Installing/Removing Hard Drives
1. To remove a carrier, first open the front bezel.
2. Push the release button located beside the drive LEDs (See Figure 6-5).
3. Swing the handle fully out and then use it to pull the unit straight out.
Note: Your operating system must have RAID support to enable the hot-swap
capability of the drives.
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 (see Figure 6-6).

Warning: Use extreme caution when working around the SAS/SATA backplane. Do
not touch the backplane with any metal objects and make sure no cables touch the
backplane or obstruct the airflow holes.

SAS/SATA Backplane

The SAS/SATA drives plug into a backplane. Two cables need to be connected from
the serverboard to the appropriate connectors on the backplane to support eight
SAS or SATA drives. You cannot cascade the backplane.
