Caution: Do not remove a NAC Controller PEP from an operating chassis system before reading

the following information and instructions.

Precaución: Antes de retirar los módulos DFE del chasis en funcionamiento, lea las siguientes

instrucciones y la información suministrada.

Note: The only safe time to pull a chassis out of the chassis is when the CPU LED is alternately

flashing amber/off. Otherwise, system operation will be interrupted.

Caution: This method of shutting down a NAC Controller PEP is not recommended except as a last

resort, because all processes currently running on the module will be interrupted resulting in loss of

frames.

Precaución: No se recomienda utilizar este método para apagar los módulos DFE. Recurra a él

sólo como último recurso, puesto que interrumpe todos los procesos del módulo en

funcionamiento, lo que podría resultar pérdidas de frames.
