Line Cards
Line cards provide external interfaces for connections to other network devices and are hot-swappable.
There are seven line card slots numbered 0 through 6. The ports are numbered from the top, starting from
0.
WARNING: The line card temperatures in E600i slots 0 and 1 rise above 80 F if traffic is flowing at line rate in
a fully loaded chassis.
Line Card LEDs
Line card LEDs are described in the documentation specific to each line card. Refer to the installation
documentation that came with the card.
Switch Fabric Modules
SFMs plug into the backplane and carry traffic between line cards or between RPMs and a line card. A
minimum of four SFMs are required in order for the E-Series system to operate properly. There is an
additional slot available for a redundant SFM; if you are not operating the system with SFM redundancy,
install a blank panel in the unused slot.
