SIMM Upgrades

3.5SIMM UPGRADES

The ESX allows memory upgrades for Shared DRAM, Local DRAM, and FLASH EEPROM. This section explains how to locate and add/replace a Single In-line Memory Module (SIMM) for any of these memory types.

Cabletron Systems currently offers an 8 MB upgrade for Local and Shared DRAM (Part Number 8MB-SCM-UGK-60).

3.5.1Locating SIMMs

Each memory type has a specific SIMM slot location on the ESX motherboard. When installing SIMM boards, make sure that you place them in their proper slots. Figure 3-4 shows the location of the ESX SIMM slots.

3.5.2Installing SIMMs

The ESX has two SIMM slot types. FLASH SIMMs use an angle-down slot (where the SIMM rotates down to a horizontal locked position). SDRAM and LDRAM SIMMs use an angle-up slot (where the SIMM rotates up to a vertical locked position).

Installing a SIMM in either slot is a simple two-step process. After finding the proper SIMM slot location (Figure 3-4), refer to the proper illustration and procedures for each SIMM slot type.
