Caution: The router detects error and warning conditions by comparing the
number of power modules detected to the number of power modules in the
configuration information. If a power module is added or removed, the power
supply configuration must be updated to ensure the proper warning and error
conditions will be detected.
Caution: To prevent static shock, which can damage electrical equipment, use
industry accepted handling practices when servicing the router and its
components. See Appendix E , “Electrostatic Discharge,” for more information.
