Replacing Cisco Content Security Appliance Components
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to
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
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
Caution When handling appliance components, wear an ESD strap to avoid damage.
Tip You can press the Unit Identification button on the front panel or rear panel to turn on a flashing Unit
Identification LED on the front and rear panels of the appliance. This button allows you to locate the
specific appliance that you are servicing when you go to the opposite side of the rack. See the “Preparing
for Cisco Content Security Appliance Component Replacement” section on page 11-2 for locations of
these LEDs.
