Memory upgrade When running Web Gateway on an older appliance model (A, B, or E in the model short code), make sure that sufficient memory (RAM) size is available. We recommend a size of at least 8 GB. You can install additional memory modules to upgrade. The appliances of the model C series already meet the current memory recommendations. When upgrading memory on any appliance model, it is important that you only install the appropriate modules for Intel-based or Dell-based appliances, depending an what model you are using. Note: Memory upgrades that follow McAfee recommendations do not void the hardware warranty. Memory modules for model B appliances (Intel-based) To obtain memory modules for appliances of the model B series, contact your McAfee sales person. These modules are (like the appliances) identified by an SKU code. The following table shows which modules are recommended for the various model B appliances.
