Questions & Answers
What is 800 Router Memory & Flash?
800 Router Memory & Flash is the built-in DRAM and flash storage subsystem on Cisco 800 Series routers that holds the operating system, configurations, and operational data.
Why should I upgrade the memory & flash on my 800 Series router?
Upgrading memory & flash enhances performance, supports larger IOS images, and enables advanced services such as VPN, firewall, and QoS.
How much DRAM does the 800 Series router support?
The Cisco 800 Series router supports up to 256 MB of DRAM, providing sufficient capacity for multitasking and feature expansion.
What flash capacity is available for the 800 Series router?
800 Series routers include 32 MB to 64 MB of onboard flash and support external CompactFlash expansion up to 512 MB.
How do I upgrade DRAM on an 800 Series router?
Power off the router, open the chassis, replace the existing DRAM SIMM with a compatible module, then reassemble and power on.
How do I expand flash memory on my 800 Series router?
Insert a supported CompactFlash card into the external slot, then set the boot variable to the new flash location with the `boot system` command.
Which memory modules are compatible with the 800 Series router?
Install 72-pin, 16-bit SIMM modules rated at 60 ns or faster, as specified by Cisco for the 800 Series.
Can I operate the router while upgrading memory or flash?
No. You must power down the router before installing or removing DRAM or CompactFlash to prevent hardware damage.
How do I check current memory and flash usage?
Use `show version` to display DRAM details and `show flash:` to view flash capacity and utilization in privileged EXEC mode.
How can I back up my flash memory before an upgrade?
Run `copy flash: tftp:` or `copy flash: usbflash0:` to transfer all flash files to a TFTP server or USB storage device.
What is the best practice to clear flash memory safely?
Use the `erase flash:` command in privileged EXEC mode, then reload the router to remove any residual data.
How do I recover from a failed flash update on an 800 Series router?
Enter ROMMON mode by pressing Break during boot, run `flash_init` and `load_helper`, then use TFTP to reinstall the IOS image.
What performance benefits can I expect with increased memory & flash?
More memory & flash reduces IOS reloads, supports advanced features, and improves routing convergence and VPN throughput.
How much flash memory is recommended for running multiple IOS images?
Allocate at least 128 MB of flash to store multiple IOS versions and backups for redundancy and quick rollbacks.
Is the CompactFlash card hot-swappable on the 800 Series router?
No. The CompactFlash card is not hot-swappable; always power down the router before inserting or removing the card.
How do I troubleshoot memory errors on my 800 Series router?
Use `show logging` to identify memory faults, reseat the DRAM module, verify compatibility, and replace any failing modules.
