STATUS

Required (Optional)

Note: Some enclosure features are noted as optional in the drawing below. These features may be use in some chassis designs where only top access is allowed for the cage mounting.

The EPS2U is a power supply enclosure intended to handle a power range of 400W to 700W. A mechanical drawing of the power supply cage is shown below in Figure 1.

Optional mounting features for top access mounting of the power supply.

Allow for 1.2mm protrusion (x4)
