Asus RS120-E4/PA2 - Manual (Page 26)

Chapter 2: Hardware setup 2-10
2.4 Hard disk drives
The system supports two hot-swap Serial ATA hard disk drives. The hard disk drive
installed on the left tray connects to the motherboard SATA1 (Port0) port, while the
right tray hard disk drive connects to the motherboard SATA3 (Port2) port via the
SATA backplane.
To install a hot-swap SATA HDD:
1. Release a drive tray by pushing the
spring lock to the right, then pulling
the tray lever outward. The drive
tray ejects slightly after you pull out
the lever.
2. Firmly hold the tray lever and pull
the drive tray out of the bay.
3. Take note of the drive tray holes.
Each side has three holes to fit
different types of hard disk drives.
Use two screws on each side to
secure the hard disk drive.
4. Place a SATA hard disk drive on the
tray, then secure it with four screws.
