ESCRIPTION
The UltraSPARC™–II, 400 MHz CPU, 4.0 Mbyte module, (SME5224AUPA-400) delivers high performance
computing in a compact design. Based on the UltraSPARC™-II CPU, this module is designed using a small
form factor board with an integrated external cache. It connects to the high bandwidth Ultra™ Port Architec-
ture UPA bus via a high speed sturdy connector. The UltraSPARC™–II, 400 MHz CPU, 4.0 Mbyte module, can
plug into any UPA connector, saving system design costs and reducing the production time for new systems.

Heatsinks are attached to components on the module board. The module board is encased in a plastic shroud.
The purpose of this shroud is to protect the components and channel airflow. Module design is geared
towards ease of upgrade and field support.
