Battery-Backed RAM (AR725, AR745, AR770S only)

The AR725 and AR745 have 128 kB of battery-backed SRAM as NVS (non- volatile storage), and the AR770S has 512 kB. The router can store files such as logs and configuration scripts in NVS over a power cycle.

Onboard Flash Memory

Flash memory is a nonvolatile 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.

There are two types of flash—onboard flash (flash connected directly to the router’s PCB and available on all routers), and CompactFlash (flash provided by removable compact flash cards). All the routers have onboard flash memory; AR725 and AR745 routers also have a slot for compact flash cards. (“CompactFlash (AR725, AR745 only)” on page 41)

Of the router’s onboard flash memory, 1 MB is reserved for the flash boot version. You can use the rest to store files in the flash file system, such as a software version file, GUI resource file, configuration scripts and command line help file. The router also stores system files in the flash file system.

Testing Onboard 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, using the command:

show system

to display system information (Figure 12 on page 38). 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, enter the command:

show flash physical

to display flash memory size, device type and location.
