Replacing a power supply
Complete the following steps to replace a power supply in the switch. Refer to
Figure 21 and Figure 22 on page 41 for this procedure.
1. To leave the switch in service while replacing a power supply, verify that the
other power supply (the one not being replaced) has been powered on for at
least four seconds and has a steady green status LED.
2. Unplug the power cord from the power cord receptacle (
7
in Figure 21) of the
power supply that is being replaced.
3. Push the locking tab (

) to the left and hold it there while using the handle
(

) on the power supply to pull it straight out and away from the chassis.
Pull the power supply out slowly to avoid catching a finger on the locking tab.
