SSDs
The Secure Firewall 4200 has two SSD slots that each hold one NVMe 1.8-TB SSD. By default the Secure
Firewall 4200 ships with two 1.8-TB SSDs installed in slot 1 and slot 2. Software RAID1 is shipped already
configured.
Hot swapping is supported. You can swap SSDs without powering off the chassis. However, before hot
swapping SSDs you must issue the raid remove-secure local-disk 1|2 command to prepare the SSD for
removal. This command preserves the data on the SSD. After you remove and replace the SSD, you must add
it again to the RAID1 configuration using the raid add local-disk 1|2 command.
The raid remove-secure local disk command securely erases the specified SSD data.
Caution
You cannot swap SSDs between different platforms. For example, you cannot use a 3100 series SSD in a
4200 series model.
