Chapter 3: Maintenance and Component Installation
Motherboard Battery
The motherboard uses non-volatile memory to retain system information when system power
is removed. This memory is powered by a lithium battery residing on the motherboard.
Replacing the Battery
Begin by removing power from the system as described in section 3.1.
1. Push aside the small clamp that covers the edge of the battery. When the battery is
released, lift it out of the holder.
2. To insert a new battery, slide one edge under the lip of the holder with the positive (+)
side facing up. Then push the other side down until the clamp snaps over it.
Note:
Handle used batteries carefully. Do not damage the battery in any way; a damaged
battery may release hazardous materials into the environment. Do not discard a used battery
in the garbage or a public landfill. Please comply with the regulations set up by your local
hazardous waste management agency to dispose of your used battery properly.
3.4 Chassis Components
Hard Drives
The SC213 chassis features sixteen 2.5" drive bays accessible from the front of the chassis.
The drives are mounted in drive carriers to simplify their installation and removal. These
carriers also help promote proper airflow for the drive bays.
The hard disk drive are sold separately. Enterprise level hard disk drives are recommended
for use in Supermicro chassis and servers. For information on recommended HDDs, visit the
Supermicro website at http://www.supermicro.com/products/nfo/files/storage/SAS-CompList.
Removing a Hot-Swap Drive Carrier
1. Press the release button on the drive carrier. This extends the drive bay handle.
2. Use the handle to pull the drive out of the chassis.
3. Remove the dummy drive from the carrier.
Mounting a Drive in a Drive Carrier
1. To add a new drive, install it 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 the screws provided, then push the carrier
completely into the drive bay. You should hear a *click* when the drive is fully inserted.
This indicates that the carrier has been fully seated and connected to the midplane,
which automatically makes the power and logic connections to the hard drive.
