Remove and Replace Cisco 4000 Series ISRs Power Supplies
Replace AC Power Supply
Caution
Care should be taken while removing the power supplies and PoE power supply, especially in boost mode
of operation. If the total power consumption is higher that can be supported by one PSU alone, and in
this condition, if a PSU is removed, the hardware can be damaged. This may result in the system being
unstable or unusable.
Similarly, if there is only one PoE power supply and it is providing PoE power to an SM-X, in this
condition if the PoE power supply is removed, the hardware may be damage and may result in the system
being unstable or unusable.
Step 1
Read the
“Safety Warnings” section on page 6-2
section and disconnect the power supply before you
replace any module.
Step 2
Remove the router bezel. The bezel is secured with snap latches. To remove the bezel, hold the top and
bottom and pull the bezel.
Step 3
Pull on the quick-release catch on the side to leverage the power supply from its connector, and then slide
the power supply module out of the chassis.
Step 4
Insert the replacement power supply module.
Step 5
Replace the bezel.
