Overview
Internal and External Flash Storage
The ASA contains one internal USB flash drive, and a standard USB Type A port that you can use to attach
an external device. The USB port can provide output power of 5 volts, up to a maximum of 500 mA (5 USB
power units).
Internal USB Device
External USB Drive (Optional)
FAT-32 File System
Solid State Drive
The ASA 5506-X and ASA 5506W-X ship with an SSD installed that provides storage support. The SSD has
50 GB of useable space and is not field-replaceable. You must return the entire ASA to Cisco for drive
replacement. The SSD is used by the software; there is no user access to the SSD.
The ASA 5506H-X ships with a ruggedized SSD installed that provides storage support. The SSD is an
industrial-rated part so that it operates over the extended temperature range that the ASA 5506H-X supports.

Power Supply Modules
The ASA 5506-X and ASA 5506W-X ship with a 12V brick power supply that provides 60 W.
The ASA 5506H-X ships with a ruggedized 5V-5.3V barrel power supply that provides 22 W. The power
supply supports an extended temperature range of -25°C to 60°C. Or you can order an optional DC power
supply that supplies 24V DC (part number PWR2-20W-24VDC) or 20W 20-60V DC (part number
PWR2-22W-20-60VDC).
Hardware Specifications
The following table contains hardware specifications for the ASA.
Online Only
An embedded eUSB device is used as the internal flash; it is identified as disk0.
You can use the external Type A USB port to attach a data-storage device. The external USB drive
identifier is disk1. When the ASA is powered on, a connected USB drive is mounted as disk1 and is
available for you to use. Additionally, the file-system commands that are available to disk0 are also
available to disk1, including copy, format, delete, mkdir, pwd, cd, and so on.
If you insert a USB drive with more than one partition, only the first partition is mounted.
The ASA only supports FAT-32-formatted file systems for the internal eUSB and external USB drives.
If you insert an external USB drive that is not in FAT-32 format, the system mounting process fails, and
you receive an error message. You can enter the command format disk1: to format the partition to
FAT-32 and mount the partition to disk1 again; however, data might be lost.
