C Series System Description
The C Series Controller enables you to easily install, configure, and support Juniper Networks Session and Resource Control (SRC) software. It provides easy access to troubleshooting information, such as reporting events, logs, and system dumps while providing session resource controller functionality.
There are two C Series Controller models: the C3000 model and the C5000 model. Each model is composed of four hard drives, three fan modules, redundant power supplies, one USB port, a console management port, and four Ethernet ports.
Both models use the same software. However, the specific model determines the number of service session licenses and concurrent subscribers allowed on each unit. (See Table 1.)
