How to install MEM-4400-4GU16G

• Power down the Cisco ISR router and disconnect it from power to ensure a safe upgrade.
• Ground yourself to prevent static discharge before handling memory modules.
• Open the router’s memory access panel per the Cisco hardware guide for the ISR 4431/4451 series and locate the available memory slots.
• If replacing existing memory, carefully remove the existing DIMMs following the device manual. If adding memory alongside existing modules, ensure you insert the kit into the correct slots as specified by Cisco documentation.
• Insert the MEM-4400-4GU16G DDR3 memory modules firmly into the slots, ensuring proper orientation and seating. Avoid tilting; press evenly until the modules click into place.
• Re-seat any adjacent modules, close the memory cover, reconnect power, and boot the router.
• Once the device powers up, verify that the new memory is recognized by the router. Use the supported CLI commands to confirm total installed memory and ensure there are no memory errors.
• Test a lightweight workload to confirm stability, then monitor the router’s performance under typical traffic conditions to confirm the upgrade’s benefits.
