Figure 21 R4300 Modules
The Connect Module (shown on the left in Figure 20) provides connectors for C/Ports,
USB ports, and sparing. On the right, the Network Module (either Model R4362 [EP6] or
Model R4363 [EP2]) provides Ethernet connections. In the center, the Remote
Management Module provides network and daisy-chain control connections, chassis
health indicators, and fan speed control. The Status LEDs in the blue area above the
Management Bay are shared between the sets of connectors to provide information about
each kind of connection to each blade in a manageable fashion.
Table 4 on page 28 provides details of the features of the modules, and describes their
interactions. Note that some features are color-coded to show that their functions are
inter-related. For example, features coded blue are for monitoring the status of the
various connection ports on the R4300.
