Module Details

ERX-7xx/14xx models use up to two redundant SRP modules operating in an
active/standby configuration. ERX-310 routers use only one SRP module. An SRP
module must be present for any system to boot.
SRP modules ranging from 5 Gbps to 40 Gbps can be used in ERX-7xx/14xx
models. Only a 10-Gbps SRP module (SRP-SE10G) can be used in ERX-310 routers.
See Chapter 12, Module Specifications for complete information.
Because of different physical dimensions and switch fabric capabilities, SRP
NOTE:
modules are not interchangeable between systems. For example, the 10-Gbps SRP
module used in ERX-7xx/14xx models cannot be used in the ERX-310 router, and
vice versa.
Do not remove the SRP module while the system is running.
CAUTION:
For details about installing SRP modules, see Chapter 5, Installing Modules.
