| MISCELLANEOUS TECHNICAL NOTES |
|------------------------------------------------------------|
| The controller cannot use caching without the CM401X |
| caching module. The MM401X memory modules cannot operate |
| without the caching module. |
| |
| The memory modules come in 2MB and 4MB size but can only |
| be installed one at the time unless the MX401X expansion |
| card is connected to the controller. |
| |
| DM401X is the disk mirroring module which provide RAID 1 |
| disk mirroring capability. |
