Other Electrical Problems
Table 2-4 lists the AC PEM fault indications and recommended actions.
Other Electrical Problems
If the electrical problem cannot be traced to a PEM, check the unit for:
• Improper power cable connections to the Cisco 10000 series router
• Improper installation of other field-replaceable units (FRUs)
Check the site for:
• Improperly grounded equipment, particularly equipment racks and power grounds
• Fluctuating voltage, which can result from excessive power drains caused by other equipment (such
as air conditioning units)
• Cable corrosion or defective power panels, circuit breakers or fuses, or cable connections
• Undersized power cables or excessive power cable lengths
• Excessive power demand on backup power systems or batteries when alternate power sources
are used
