ERX-310 router

For details about available line modules and compatibility between line modules and SRP modules, see the ERX Module Guide.

Slot Groups

The slots in the ERX-1410 router and ERX-7xx models 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 router or the ERX-310 router. In the ERX-310 router, slot 0 contains the SRP module and slots 1 and 2 each contain a line module.

Slot Groups for the ERX-1410 Router

A slot group in the ERX-1410 router comprises three adjacent chassis slots. The groups for the ERX-1410 router consist of the following slots (Figure 17):

Slot group 1—Slots 0 through 2

Slot group 2—Slots 3 through 5

Slot group 3—Slots 8 through 10

Slot group 4—Slots 11 through 13

Slots 6 and 7 are reserved for the SRP modules.
