How to upgrade Supervisor Engine 1A DRAM in Catalyst 6500 series switches



The MEM-S1-128MB= memory upgrade kit consists of two 64-MB DRAM, Dual Inline Memory Modules (DIMMs). The memory upgrade kit upgrades the total Supervisor Engine memory from 64 MB (2 32-MB DIMMs) to 128 MB (2 64-MB DIMMs).

Issue the show version command to display the total DRAM installed on the Supervisor Engine.

To upgrade to 128-MB DRAM on the WS-X6K-SUP1A-MSFC, use the MEM-S1-128MB-UPG= upgrade kit, which also includes an MSFC2 upgrade. All other Supervisor Engine 1A modules can upgrade to 128-MB DRAM, using the MEM-S1-128MB= upgrade kit.

The DRAM DIMMs on the Supervisor Engine 1A with an MSFC (WS-X6K-SUP1A-MSFC) are located beneath the MSFC. The MSFC is not field replaceable. Re-installing the MSFC could damage your Supervisor Engine. To upgrade the DRAM, you must also upgrade the MSFC to an MSFC2. Both upgrades are available in the MEM-S1-128MB-UPG= upgrade kit.

For step-by-step instructions for the MEM-S1-128MB-UPG upgrade, refer to Catalyst 6500 Series Supervisor Engine 1A DRAM Upgrade Installation Note.
