Replacing a Hard Disk or Solid State Drive
The PA-5000 Series firewall has a bay that contains two 2.5-inch Serial Advanced Technology
Attachment (SATA) hard disk drives or solid state drives (SSD). You must power down the firewall to
replace either of the drives.
To replace a drive:
1. Identify the failed drive using the system log. The drive LED indicates if a drive is failed, but does
not indicate which drive.
2. Power down the firewall.
3. Loosen the thumbnail screws for the disk drive bay using a flat or Phillips head screw driver, if
necessary.
Note: If enabled, an audible alert will be sound until two power supplies are
installed and operational. The audible alert is disabled by default and can be
enabled by running set system setting power-supply audible-
alarm enable yes.
