Determining the status of a system fabric module

Determining the status of a system fabric module
At least one functional switch fabric module (SFM) must be plugged into slots S1 or S2 (the “control
plane slots”). If there are no functional SFMs in either slot during bootup, bootup is halted with a
message indicating that condition.
In an operational chassis, if all SFMs in the control plane slots become faulty or are removed, then
all the line cards will be faulted with a reason code that indicates no availability of an SFM. An
external raslog message will also be displayed.
Complete the following steps to determine the status of an SFM.
1. Check the LED indicators on the SFM (refer to Figure 8 ). The LED patterns may temporarily
change during POST and other diagnostic tests. For information about how to interpret the LED
patterns, refer to
Table 11 .
2. You can use the show sfm command or the show slots command to see whether the SFM is
enabled.
Figure 8 identifies the switch fabric module.
