Removing PWR-1900-DC Power Supply from a Cisco 7606 Router
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Warning
Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock,
keep hands and fingers out of the power supply bays and backplane areas.
Follow these steps to remove a DC-input power supply:
Step 1
Verify that power is off to the DC circuit connected to the DC PEM for the power supply you are
removing (
Figure 5-17
). The location of the PEMs is the same for AC and DC PEMs on the Cisco 7603
and Cisco 7606 routers.
