ERX-310 SRP Module - SRP module for the ERX-310, used with EX3-310ACIG-SYS and EX3-310DC1G-SYS systems and requires EX3-SRP-IOA. 1G of on board SRP memory. Each Base System requires one SRP and one SRP I/O for operation. A second SRP can be added for a redundant system (except the ERX-310, which only supports a single SRP). The 5 and 10 Gig SRP supports all line module options, the 40 Gig SRP works with high speed line modules only.
