Cisco ASA 5506W-X Software Image Upgrade

It's been a while since I've configured a Small Office/Home Office (SOHO) firewall such as the Cisco ASA 5505. I had a nice online deal for a Cisco ASA 5506W-X for my home lab and made sure the appliance Version ID (VID) wasn't affected by the clock signal issue, otherwise it might get "bricked" sometime in the future. I considered getting a Cisco ASA 5506W-X and paid extra for the built-in wireless AP since my home users got wifi on their smart phones and tablets.

Here's a nice link for some tips in choosing a Next-Generation Firewall (NGFW). Below are photos of the good old Cisco ASA 5505 firewall.



Below are the photos of the Cisco ASA 5506W-X. It has a metallic chassis with lots of holes (for heat ventilation). You can find the LED status lights on top.


This is the front panel.


This the back panel with all the ports. You can also view the LED light status in here.


This is the power adapter (ASA5506-PWR-AC).


Compared to the old Cisco ASA 5505 firewall, the Cisco ASA 5506 has 8x Layer 3 only (routed) gig ports (no PoE) and 1x Management port (for FirePower only), it has the FirePOWER module (SSD drive) installed, it supports ASDM to manage the "classic firewall" and the FirePOWER module (starting on 6.0).

Below is the image and ASDM when it was shipped and the configuration after I did a write erase and reload on the appliance.

Whenever deploying any Cisco appliance in production, it's best practice to upgrade using the TAC recommended software. As of this writing, these are ASA 9.8.2 and ASDM 7.9(2). You'll also need to check for the ASA software and ASDM compatibility matrix.



Check the ASA flash memory and the hard coded ASA image and ASDM.
