Cisco MEM-VIP4-256M-SD enterprise networking (router/Catalyst switch/UCS families) Telecom System Card / Module

The Cisco MEM-VIP4-256M-SD is a 256MB SDRAM memory option for the Versatile Interface Processor 4 (VIP4) card fitted to Cisco 7500 series routers. The VIP4 is a distributed processing interface card that handles packet forwarding for the WAN and LAN port adapters fitted to it, offloading that work from the router’s central Route/Switch Processor, and this memory upgrade raises the SDRAM available to the VIP4 for larger routing tables, distributed Cisco Express Forwarding, and heavier per-interface feature processing than its base memory configuration supports. Genuine spares are a routine requirement for bringing an existing VIP4 up to a supported memory specification or restoring one to full capability after a fault. Specifiers should confirm the exact VIP4 variant and target IOS feature set before ordering. Tech-Star (UK-based, shipped worldwide) stocks Cisco memory upgrades to support ongoing network maintenance projects.
