- Auto frame format sensing
- Requires a fan assembly
- Operates in any chassis, from any MS slot designated for DS1 service.
For redundant operation, the slot pairs are as follows: - MX chassis: slots 3&4, 7&8, and 9&10
- SMX chassis: slots 3&4
- LMX chassis: slots 1&2, 3&4, 5&6, 7&8, 9&10, 11&12, 13&14, 15&16, 17&18, 19&20, 21&22, and 23&24
