Set the power switch to the off (0) position. If you have redundant PEMs, set only the power switch of the PEM you are replacing to the off (0) position (the example in Figure 5-21 shows the top PEM in the off position). Caution Do not power off both of the DC PEMs in a redundant system, or the system shuts and down all data traffic stops. Only power off the DC PEM you are replacing. 5-20 Cisco 10008 Router Hardware Installation Guide OL-0659-13
