==Summary==
The <b>Memory expansion</b> provides the possibility to expand the router's flash memory with a USB mass storage device. This page is an overview of the Memory expansion page of {{{name}}} routers.

==Prerequisites==
To be eligible for router memory expansion, the USBMSD must qualify the following imposed restrictions:
<ul>
<li>The USB must be the first one inserted. (For example, if you are using a USB hub, the eligible device is the first USBMSD attached to the hub.)</li>
<li>The first partition of the USBMSD must be the primary partition.</li>
<li>The size of the first primary partition must be at least 512 MB</b>.</li>
<li>The filesystem of the first primary partition must be ext2.</li>
</ul>
----
Take serious notice of the warnings displayed in the Memory expansion page. Here's what you need to know <b>before enabling memory expansion</b>:
<ul>
<li>Memory expansion procedure will reboot the router.</li>
<li>When reversing the memory expansion procedure, the router will be reverted to the state it was before the procedure. Make sure to fully configure the router before the procedure.</li>
<li>The procedure will erase all existing files from the USBMSD.</li>
<li>Samba shared directories on /mnt/sda1 will be deleted.</li>
</ul>
----
Here's what you need to know <b>before disabling memory expansion</b>:
<ul>
<li>Disabling memory expansion will reboot the router.</li>
<li>Disabling memory expansion will revert the router to the state it was before the memory expansion. This may leave router unconfigured if it was so before the expansion.</li>
<li>Do not unplug the USBMSD before disabling memory expansion.</li>
</ul>
==Memory expansion==
It is highly recommended that you read the <b>[[#Prerequisites|Prerequisites]]</b> section or read the notes and warnings displayed in the WebUI page before enabling memory expansion.
----
If you insert a drive of a wrong format (not ext2), you will see a warning message like this:
[[File:{{{file_format}}}]]
----
If there is no drive inserted or there is another problem with the drive, you will see a warning message like this:
[[File:{{{file_warning}}}]]
----
If everything is correct, simply enable memory expansion. save changes and wait for the router to reboot.
[[File:{{{file_memory}}}]]

You can later check the router's memory state with the Linux <i>df</i> command or via the System widget in the Status → [[{{{name}}} Overview|Overview]] page:
