Chapter 3: Setup and Installation

3-4 Onboard Battery Installation

A battery is included on the mainboard to supply certain volatile memory components with power when power has been removed from the blade module. If this battery dies, it must be replaced with an equivalent CR2032 Lithium 3V battery. Dispose of used batteries according to the manufacturer's instructions. See Figure 3-12for a diagram of installing a new onboard battery.

Caution: There is a danger of explosion if the onboard battery is installed upside down, which reverses its polarities.

3-5 Memory Installation

The mainboard of each blade unit must be populated with DIMMs (Dual In-line Memory Modules) to provide system memory. The DIMMs should all be of the same size and speed and from the same Super Micro authorized manufacturer due to compatibility issues. See details below on supported memory and our web site (www.supermicro.com/products/superblade for recommended memory.

Caution: For all SBI-7427R series blades, ONLY VLP (Very low profile) memory can be used.

Populating Memory Slots

The mainboard of a SBI-7127R-S6 blade module has sixteen (16) memory slots, eight for each processor. Both interleaved and non-interleaved memory are supported, so you may populate any number of DIMM slots.

Populating two slots at a time (DIMM1A + DIMM2A, DIMM3A + DIMM4A, etc.) with memory modules of the same size and of the same type will result in dual-channel, interleaved memory, which is faster than single-channel, non-interleaved memory. See Table 3-1: "Populating Eight Memory Slots for Interleaved Operation" on page 3-10for details.

For an interleaved configuration, memory modules of the same size and speed must be installed in pairs. You should not mix DIMMs of different sizes and speeds.
