For details about available line modules, see Appendix B, Module Specifications.

Slot Groups

The slots in the ERX-700 series' and the ERX-1410 system's chassis are divided into groups. The number of groups and number of slots per group depend on the system. There are no slot groups in the ERX-1440 system.

Slot Groups for the ERX-1410 System

A slot group in the ERX-1410 system comprises three adjacent chassis slots. The groups for the ERX-1410 system consist of the following slots (Figure 3-2):

Slots 6 and 7 are reserved for the SRP modules.
