2-32Removing a power moduleCAUTION:• When an S6850-56HF, S6850-2C, or S9850-32H switch has two power modules in 1+1redundancy mode, removing one power module does not affect the operation of the switch.When the switch has only one power module installed, removing the power module powers offthe switch.• When an S9850-4C switch has power modules in 2+1 or 2+2 redundancy mode, removing one ortwo power modules does not affect the operation of the switch. When the switch has only twopower modules installed, removing power modules powers off the switch or causes powerinsufficiency.The LSVM1AC650 and LSVM1DC650 removal procedure is the same on the S6850 and S9850series switches. The figures in this section use the S6850-56HF switch as an example.To remove a power module:1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.2. Remove the power cord from the power module. To remove a DC power cord, squeeze the tabson the power cord connector with your thumb and forefinger, and then pull the connector out, asshown in Figure2-53.3. Hold the handle on the power module with one hand, pivot the latch on the power module to theright with your thumb, and pull the power module part way out of the slot, as shown inFigure2-54.4. Supporting the power module bottom with one hand, slowly pull the power module out with theother hand.5. Put the removed power module in an antistatic bag for future use.6. If you are not to install a new power module, install a filler panel in the slot to ensure goodventilation in the switch, as shown in Figure2-55.
