— If the enabled LED on the SP (or SSP) is not on, suspect that the processor has shifted out of
its slot. Turn all system power off, then use the processor ejector levers to ensure that the
processor is seated in the backplane. Push the top lever down while pushing the bottom lever
up until both levers are at a 90-degree orientation to the rear of the chassis. (For a description
and illustration of the ejector levers, refer to the section "Ejector Levers" in the chapter
"Maintenance.") Tighten the captive installation screws at the top and bottom of the SP
faceplate and restart the system.
— If the enabled LED on an interface processor is not on, suspect that the interface processor
has shifted out of its slot. You do not have to turn off the system power to remove and replace
an interface processor, but you must turn off the power before removing an RP or SP. Use
the ejector levers to ensure that the interface processor is seated in the backplane. Push the
top lever down while pushing the bottom lever up until both levers are at a 90-degree
orientation to the rear of the chassis. (For a description and illustration of the ejector levers,
refer to the section "Ejector Levers" in the chapter "Maintenance.") Tighten the captive
installation screws at the top and bottom of the interface processor faceplate. After the
system reinitializes the interfaces, the enabled LED on the interface processor should come
on.
