Internet2 - Chassis Environmental Monitoring

The Juniper routers keep detailed temperature information on each item in the chassis, from the Power Supplies (PEM) and Control Boards (CB), to the Switch Interface Boards (SIB) and the Flexible PIC Concentrators (FPC.) The routers also monitor the status of the various fans inside the system, as well as the status CIP and SPMB. A more detailed explanation of the various parts of the routers can be found on the Hardware Inventory page.

The M5's have a chassis that's not at all like the T640's, so they appear at the end of the page.
