Power-Supply Module Installation
Installation Guidelines
Observe these guidelines when removing or installing a power-supply module:
A power-supply module that is only partially connected to the router disrupts the system operation.
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
Warning
Do not reach into a vacant slot while installing or removing a module. Exposed circuitry is an energy
hazard. Statement 206
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning
Avoid using or servicing any equipment that has outdoor connections during an electrical storm. There
may be a risk of electric shock from lightning. Statement 1088
