Memory Options
Your AR400 Series Router comes with Flash memory installed. This is a
non-volatile, reprogrammable, memory storage device for router software
versions, allowing upgrades to be remotely loaded from any WAN or LAN
port. Flash memory is also used to store other types of data such as patches,
logs and configurations.
Testing flash
memory
There are several ways to check that onboard flash memory is installed and
operating correctly. First, check that the router has recognised the flash
memory by displaying system information (
Figure 2
) with the command:
show system
Figure 2: Example output from the
show system
command for the AT-AR450S router
The second part of the display shows the types and sizes of memory installed
in the router. If the flash memory size is lower than expected, then the router’s
boot process has not correctly detected or recognised the flash memory’s
presence. If recognition fails, contact your authorised Allied Telesis distributor
or reseller.
If the flash is recognised, display flash memory size, device type, and location
with the command:
show flash physical
A typical display is shown in
Figure 3 on page 20
