Powering Up Cisco 1800 Series Routers
Warning
The plug-socket combination must be accessible at all times because it serves as the main
disconnecting device.
Statement 1019
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 To ensure adequate cooling, never operate the router unless the unit is completely closed.
