7 Installing RPMs, Line Cards, and SFMs This chapter provides instructions to install cards into the E-Series chassis and includes the following sections: • Install RPMs, Line Cards, and SFMs • Remove RPMs, Line Cards, and SFMs Route Processor Modules The system requires at least one Route Processor Module (RPM), two RPMs provide redundancy. Chassis slots R0 and R1 are RPM slots. They are keyed to fit into these slots and not line card slots to prevent improper installation. You can insert a second RPM into an online system without performance interruption or software intervention. A second RPM provides redundant functionality and uninterrupted performance if the system transitions from the active RPM to the standby RPM. RPM LEDs Table 7-1 describes the RPM LED states. Table 7-1. RPM LEDs Section Management Label 10/100 Ethernet Alarms Major Minor LT Flash Primary Description L: Green: link is up A: Green: activity on port Red: a critical condition exists, such as a severe over-temperature condition, a fan tray failure, an over-current condition in a power supply, or an out-of-tolerance voltage. The RPM LEDs are controlled by software which sets the threshold levels for triggering the different stages of alarms. Unlit: no major conditions. Amber: a serious condition exists, such as an over-temperature condition, a single fan failure, or a line card failure. The RPM LEDs are controlled by software, which sets the threshold levels for triggering the different stages of alarms. Unlit: no minor alarm conditions. Allows you to test the operability of LEDs to verify that they are able to light. Press the LT button to temporarily illuminate the LEDs on the RPM. Green: flash memory card is in the process of a read or write process. Do not remove the flash card when the In Use LED is lit. Unlit: not in use.
