Cables, mounting screws, and documentation are typically sold separately or provided by your system integrator.

4. Nastavení a instalace

4.1. Předpoklady

• A server, workstation, or NAS enclosure with available 3.5-inch drive bays.
• A compatible SAS Host Bus Adapter (HBA) or RAID controller. Ensure the HBA supports 12Gb/s SAS and drive capacities of 20TB or higher.
• Appropriate SAS data cables (e.g., SFF-8643 to SFF-8482 for direct connection, or SFF-8643 to SFF-8643 for backplane connections).
• Napájecí zdroj (PSU) s dostatečným výkonemtaga dostupné napájecí konektory.
• An operating system that supports large capacity drives (e.g., Windows Server, Linux, FreeBSD).

4.2. Fyzická instalace

1. Připravit: Power down your system and disconnect the power cord. Open the computer case or server enclosure.
2. Připojení disku: Secure the hard drive into an available 3.5-inch drive bay using appropriate mounting screws. Ensure the drive is firmly seated to minimize vibration.
3. Připojení datového kabelu: Connect one end of the SAS data cable to the SAS port on the hard drive (SFF-8482 connector) and the other end to an available port on your SAS HBA or RAID controller.
4. Připojte napájecí kabel: Connect a standard SATA power connector from your PSU to the power input on the hard drive.
5. Address PWDIS (Power Disable Feature) - Important Note: Some newer SAS drives, including certain Exos models, may incorporate the SATA 3.3 Power Disable (PWDIS) feature. If your system's backplane or power supply applies 3.3V to Pin 3 of the SATA power connector, the drive may not spin up.
   • Příznaky: Drive is not detected, or does not spin up.
   • Řešení: If experiencing this issue, you may need to use a power adapter cable that does not connect the 3.3V line to Pin 3, or physically isolate Pin 3 on the drive's power connector. Consult your system's documentation or search for "SATA 3.3 PWDIS" for detailed solutions. This is a common consideration for enterprise drives in certain older or non-compliant systems.
6. Zavřít systém: Once all connections are secure, close your computer case or server enclosure.

4.3. Inicializace disku

1. Zapnutí: Reconnect the power cord and power on your system.
2. Konfigurace BIOSu/UEFI: Access your system's BIOS/UEFI settings or the SAS HBA/RAID controller's configuration utility to verify that the drive is detected.
3. Rozpoznávání operačního systému: Once the operating system loads, the drive should be recognized. For Windows, open Disk Management. For Linux, use commands like lsblk or fdisk -l.
4. Inicializace a formátování: The drive will likely appear as "unallocated space." You will need to initialize the disk (GPT for drives larger than 2TB), create partitions, and format them with a suitable file system (e.g., NTFS, ext4, ZFS) before use. Refer to your operating system's documentation for detailed steps on disk initialization and formatting.
