DIMM installation guidelines
Observe the following guidelines when installing additional memory:
In a BL860c i2 Server Blade, memory is loaded in pairs.
In a BL870c i2 or BL890c i2 Server Blade, memory is loaded in quads that alternate between
blades.
Only two DIMM sizes can be mixed in a BL870c i2 or BL890c i2 Server Blade.
◦
In a BL870c i2 Server Blade, the two DIMM sizes must alternate between blades. Load
all of one DIMM size, then repeat with the second DIMM size.
◦
In a BL890c i2 Server Blade, blades 1 and 2 must have one DIMM size and blades 3
and 4 must have the other DIMM size. If only one DIMM size is used on BL980 i2,
alternate between all 4 blades.
