Acer Altos R520 manual Configuring the storage devices, Removing and installing a hard disk drive

50 3 System upgrade

Configuring the storage devices

The system supports 2.5-inch storage devices. It accommodates slim- line optical drives and depending on system model, can support up to six 2.5-inch hot-plug SATA hard disk drives or eight hot-plug SAS hard disk drives.

Caution! To maintain proper system cooling, filler panels must be installed if a device is not replaced.

Removing and installing a hard disk drive

Note: Use only Acer-qualified SAS or SATA HDDs. To purchase a SAS or SATA HDD, contact your local Acer representative.

Caution! To ensure proper airflow and server cooling, all drive bays must contain either a carrier with a hard drive installed in it or a hard disk carrier cover.

Determining drive status

Each HDD carrier features two status LED indicators to display the hard drive status. If you are replacing a failed HDD, determine which drive has failed by checking the drive status LED. For more information on how to determine the drive status, refer to “Hot-plug HDD LED indicators” on page 25.
