Removing a power supply
CAUTION:
• If the switch has two power supplies, removing one power supply does not affect the operation of the switch. If the
switch has only one power supply, removing the power supply powers off the switch.
• The power cord color code scheme in
Figure 22: Removing the DC power cord on page 30 is for illustration only.
The cable delivered for your country/region might use a different color scheme. When you connect the power cord,
always identify the polarity symbol on its wires.
Procedure
1. Wear an ESD wriststrap and make sure it makes good skin contact and is reliably grounded.
2. Squeeze the tabs on the power cord connector with your thumb and forefinger, and pull the connector out to remove the
power cord, as shown in
Figure 22: Removing the DC power cord on page 30.
3. Hold the handle on the power supply with one hand, pivot the latch on the power supply to the right with your thumb, and
pull the power supply part way out of the slot, as shown in
Figure 23: Removing the power supply on page 30.
4. Supporting the power supply bottom with one hand, slowly pull out the power supply with the other hand.
5. Put away the removed power supply in an antistatic bag for future use.
