To display the available file systems on your switch, use the show file systems privileged
EXEC command as shown in this example :

Switch# show file system

“if it say’s “Unknown“, this means the USB pen drive inserted is uncompatible or not formatted
to fat32 partition”.

To see the contents within the USB pen inserted into Cisco ASA hardware :

Run this command in exec mode :

dir disk1:

Directory of disk1:/

134 -rwx 89837568 10:32:20 Jan 09 2017 asa962-smp-k8.bin
135 -rwx 26053720 10:51:02 Jan 09 2017 asdm-762-150.bin

Here we see 2 firmware, 1 for the System and the 2nd is the ASDM. We will now begin the upload process :

Copy them both to flash:

copy disk1: flash:
Source filename []? asa962-smp-k8.bin
Destination filename [asa962-smp-k8.bin]?
Writing file disk0:/asa962-smp-k8.bin
89837568 bytes copied in 28.170 secs (3208484 bytes/sec)

Follow the same procedure for
copying the ASDM file

Set the system firmware to bootup on every bootup or reload of hardware :

In “configuration t” mode : enters these commands :

boot system disk0:/asa962-smp-k8.bin

Now reboot device and lets check if we are running the upgraded firmwares :

In “exec” mode :

show version

Cisco Adaptive Security Appliance Software Version 9.6(2)

Compiled on Tue 23-Aug-16 18:42 PDT by builders
System image file is “disk0:/asa962-smp-k8.bin
Config file at boot was “startup-config”

Let’s check the ASDM version the firewall is running :

show asdm image
Device Manager image file, disk0:/asdm-713.bin

We see it is running the old firmware for the ASDM and has not loaded the upgraded one. We need to tell ASA to load the specific upgraded ASDM.

Here is the command to do so : In “User” mode :

asdm image disk0:/asdm-762-150.bin

Reboot ASA and check by running command :

show asdm image
Device Manager image file, disk0:/asdm-762-150.bin


All is complete.
