Reliable and high-quality. These modules are a must-have for anyone scaling their ISE line cards to handle modern, massive routing tables.
The MEM-ISE-512A-4PK is a 1 GB route memory upgrade kit containing four 512 MB modules for two E3 service cards, designed to boost routing performance in Catalyst environments.
This kit supports Cisco Catalyst E3 route processor cards in 6500 and 7600 series switches, ensuring seamless integration with existing E3 modules.
Each E3 card receives 512 MB of additional route memory, delivering a total of 1 GB across two cards for enhanced routing table capacity.
The MEM-ISE-512A-4PK requires Cisco IOS Software release 15.2(4)S or later (31S train) to fully support and recognize the added route memory.
Power down the switch, remove the E3 card faceplate, insert the 512 MB DIMMs into the card’s memory slots, replace the faceplate, and reboot to enable the new memory.
By expanding route memory to 1 GB, the kit improves route lookup performance, supports larger BGP tables, and enhances overall network stability under heavy load.
Yes. The added memory increases routing table capacity, reducing route flapping and convergence times for BGP, OSPF and other dynamic protocols.
This memory kit carries Cisco’s limited lifetime warranty covering manufacturing defects and compatibility issues under normal operational use.
Yes. Returns are accepted within 30 days of purchase, provided the product is in original condition and packaging, in accordance with our return policy.
No additional service contract is required, but a valid Cisco SMARTnet contract ensures proactive support and software updates for full system reliability.
After reboot, use the CLI command "show platform hardware capacity" to confirm each E3 card reports an additional 512 MB of route memory.
Yes. The DIMMs include ECC (Error-Correcting Code) to detect and correct memory errors, ensuring data integrity and network stability.
Order directly through Cisco’s authorized resellers or via the Cisco online store using SKU MEM-ISE-512A-4PK for guaranteed product authenticity.
Cisco Technical Assistance Center (TAC) offers 24/7 support for installation and configuration issues under an active SMARTnet contract.
E3 cards are architecturally limited to 512 MB per module slot; the MEM-ISE-512A-4PK maximizes this capacity for two installed cards.
