ASA 5506W-X Wireless Access Point Software Compatibility
The ASA 5506W-X includes a Cisco Aironet 702i wireless access point integrated into the ASA. The access point includes an autonomous Cisco IOS image, which enables individual device management. You can install the lightweight image if you want to add the ASA 5506W-X to a Cisco Unified Wireless Network and use a wireless LAN controller. See the Converting Autonomous Access Points to Lightweight Mode chapter in the Cisco Wireless Control Configuration Guide for more information about using the lightweight image in unified mode.
The following table shows the supported software for the access point as well as the supported Cisco Wireless LAN Controller software if you convert to unified mode.

ASA 5500 and Module Compatibility
Many ASA models support service and I/O modules. This section lists the modules supported for current and legacy ASA models.
The following sections show the modules supported on each ASA model. To see the ASDM versions supported for each ASA version on your model, see ASA and ASDM Compatibility.
For the IPS module, ASDM 7.1(6) and later are not compatible with IPS 7.3(2) and earlier. To manage an IPS module on an ASA, you must connect to the IPS IP address directly through your browser.
Except for ASA CX 9.3(2), ASA Software 9.1(5) is supported up to 9.1(5.21). With 9.1(5.21) and higher, CX 9.3(2) or higher are the only supported CX releases.
Note: For ASA Version 9.3(2) and later, only ASA CX Version 9.3(2.1) and later is supported. When upgrading your ASA, first upgrade the ASA CX software; otherwise the ASA CX module can become unresponsive.
Table 14 ASA 5512-X through 5555-X CX SSP Software Compatibility
Requirements: Install in slot 1, with matching-level ASA SSP in slot 0
Note: For ASA Version 9.3(2) and later, only ASA CX Version 9.3(2.1) and later is supported. When upgrading your ASA, first upgrade the ASA CX software; otherwise the ASA CX module can become unresponsive.

The following table shows the modules supported on each ASA model. To see the ASDM versions supported for each ASA version on your model, see ASA and ASDM Compatibility.
Note: For the IPS module, ASDM 7.1(6) and later are not compatible with IDM. To manage an IPS module on an ASA, you must connect to the IPS IP address directly through your browser or in the ASDM-IDM Launcher.

ASA Clustering External Hardware Support
The following table lists supported external hardware and software to interoperate with ASA clustering.
Note: For the Firepower 9300 ASA cluster, intra-chassis clustering can operate with any switch because Firepower 9300-to-switch connections use standard interface types.
Note: Some switches, such as the Nexus series, do not support LACP rate fast when performing in-service software upgrades (ISSUs), so we do not recommend using ISSUs with clustering.

You can connect an ASA cluster directly to one or more Firepower or ASA chassis in standalone or failover mode, running either ASA or Firepower Threat Defense. For example, you might connect an Active/Standby ASA failover pair in multiple context mode to a Firepower Threat Defense cluster with inline sets (NGIPS mode).

ASA Memory Information
The ASA includes DRAM (also referred to as DIMM) and internal flash memory. On some models, you can optionally use an external flash memory as well. This section includes the following topics:
The following sections list the standard flash memory and DRAM.
Current Models
Note: The ASA 5500-X models can run a software module such as the ASA FirePOWER module alongside the ASA firewall and VPN functions. For these models, DRAM is evenly and statically distributed between the Firewall/VPN functionality and the software module functionality, with approximately 50% allocated to each. Memory for the software module is reserved even if you are not running a software module; you cannot use that memory for firewall and VPN functions. For other models with hardware modules, such as the ASA 5585-X, the modules include their own memory, so all of the ASA memory is used for firewall and VPN.

Legacy Models
See the following guidelines:
Note that the shipping DRAM increased after February 2010; the DRAM requirements for 8.3 and higher match the newer default shipping sizes. The newer default shipping DRAM is the current maximum DRAM you can install in your unit. See Memory Kits to order an upgrade kit.
ASA 5520s and ASA 5540s manufactured before August 2011 have four DIMM sockets. ASA 5520s and ASA 5540s manufactured after this date have two DIMM sockets. All ASA 5550s have four DIMM sockets.
The default internal flash memory for some models was 64 MB in the past; if you have one of these early units, we recommend upgrading your flash memory to at least the new shipping default.

Memory Requirements
The following sections list the memory requirements for current and legacy models.
Current Models
All current models include enough DRAM to run any supported release. There are no DRAM upgrade kits available. You can optionally install external flash memory to store additional images or other files. See the hardware guide for your model for more information.
Legacy Models
See the following memory requirements for legacy models:
ASA 5505—With Version 8.3 through 9.1 only the Unlimited Hosts license and the Security Plus license with failover enabled require 512 MB DRAM; other licenses can use 256 MB. For Version 9.2 and later, all ASA 5505 licenses require 512 MB.
ASA 5510, 5520, and 5540—To run 8.3 and later, you need the DRAM amount that shipped by default after February 2010. If you have an earlier unit, you must buy a memory upgrade kit. See Memory Kits.
ASA 5510 through 5550—You might need to upgrade the internal flash memory to 512 MB or add external flash memory if you load multiple images of the AnyConnect client along with one or more images of the ASA software, ASDM, client/server plugins, or Cisco Secure Desktop. In particular, you might need to upgrade for multiple AnyConnect 3.0 and higher clients with optional modules.

Viewing Flash Memory
You can check the size of internal flash and the amount of free flash memory on the ASA by doing the following:
ASDM—Choose Tools > File Management. The amounts of total and available flash memory appear on the bottom left in the pane.
CLI—In Privileged EXEC mode, enter the dir command. The amounts of total and available flash memory appear on the bottom of the output.
Example:
hostname # dir

DRAM, Flash Memory, and Failover or ASA Clustering
In a failover or cluster configuration, the units must have the same amount of DRAM. You do not have to have the same amount of flash memory. For more information, see the failover or clustering chapters in the configuration guide.
Note: If you use units with different flash memory sizes, make sure that the units with the smaller flash memory has enough space for the software images and configuration files.
