Blank faceplates and cover panels serve three important functions: they prevent exposure to
Warning
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not

Caution
this manner results in improper airflow and improper cooling that can lead to thermal damage.
On IPS sensors with multiple processors (for example, the IPS 4260 and IPS 4270-20), packets may be
