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 3-12 for a diagram of
installing a new onboard battery.
Warning: 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.
Note: For all SBI-7427 series blades, ONLY VLP (Very low profile) memory can be
used.
Populating Memory Slots
The mainboard of a SBI-7127RG-E blade module has eight (8) memory slots,
depending upon the blade model. For optimized memory bandwidth it is strongly
recommended that
ALL memory slots in this blade server module be populated by
DIMMs. DIMM layout is shown in Figure 3-13 on the next page.
