Dell PowerEdge M420 Technical Manual page 11

The Dell PowerEdge M420 implements a new module design, with a quarter-height blade server
that requires an M1000e chassis to operate. It occupies one slot vertically in the M1000e rack
chassis, which is populated with a sleeve and contains four blades. The M1000e chassis can contain
a maximum of 32 blades with eight sleeves. It can be mixed with other existing Dell blades of half-
height or full-height form factors and designed to mix with possible future half-height-double-wide
and full-height-double-wide blades.
The following sections provide external and internal views of the system and describe the module
Dell
features. For more detailed information on features and descriptions for the M420, see the
PowerEdge M420 Systems Owner's Manual
on Support.Dell.com/Manuals.
As shown in Figure 1, the M420 module supports up to two unique front-accessible, hot-plug solid
state drives (SSD) and two USB ports.
