## Summary description

Upgrade kit for Cisco devices that increases installed system memory from 512MB to 768MB. Delivered as a memory upgrade module (DD) compatible with Cisco hardware supporting this MPN. Intended to improve multitasking and buffer capacity in networking equipment, useful for routers and switches requiring higher RAM for advanced features and larger configurations.

## Long description

Memory upgrade module Cisco 512MB to 768MB - DD is a hardware kit designed to expand the installed system memory of compatible Cisco networking devices from 512MB to 768MB. This module is supplied as a replacement/upgrade memory assembly in DD configuration and is intended for Cisco routers and switches that accept this physical and electrical memory format. Increasing RAM capacity helps the device handle larger routing tables, more concurrent processes, and bigger buffers for packet handling and logging.
Advantages
The upgrade increases available system memory by 256MB without requiring a full device replacement, enabling improved multitasking and stability under load. It helps reduce memory-related performance bottlenecks when running additional features such as advanced routing protocols, security services, or larger configuration sets. The module is designed to match Cisco hardware requirements for form factor and timing when used in compatible systems.
Suitable for
 Routers and switches that originally ship with 512MB of system memory and support an upgrade to 768MB
 Environments requiring more memory for routing tables, ARP/neighbor caches, and larger configuration files
 Networks running additional services such as VPN, firewall or IP services that increase RAM usage
 Maintenance or refresh tasks where a targeted memory upgrade is preferred over device replacement
Key specifications
 Memory increase: from 512MB to 768MB (net increase of 256MB)
 Form factor: module designed for Cisco DD-style memory slots (physical module format)
 Compatibility: intended for Cisco devices that accept this upgrade module and support 768MB total system RAM
 Use case: system memory expansion for networking equipment to support larger workloads and features
How to use
Power down the device and follow Cisco's service manual or replacement instructions for your specific model before installing the memory module. Remove the chassis or access cover as required, release any retention clips, and replace the existing 512MB module with the 768MB upgrade module or install the module in the appropriate slot per the device documentation. Reassemble the device, restore power, and verify system memory has been recognized by checking the device boot messages or system status commands. Ensure firmware and software versions on the device are compatible with the increased memory.
Usage recommendations
Confirm device compatibility with the vendor documentation and, if available, test the module in a non-production environment before deploying across critical infrastructure. Back up configuration and follow electrostatic discharge (ESD) precautions during installation.
