Removing a power supply
CAUTION:

When an HPE 5930-32 QSFP+/HPE 5930-32 QSFP+ TAA/HPE 5930-2Slot+2QSFP+/HPE
5930-2Slot+2QSFP+ TAA switch has two power supplies in 1+1 redundancy mode, removing
one power supply does not affect the operation of the switch. When the switch has only one
power supply installed, removing the power supply powers off the switch.

switch. When the switch has only two power supply installed, removing a power supply might
power off the switch or cause power insufficiency.

The power cord color code scheme in
is for illustration only. The cable delivered for
your country or region might use a different color scheme. When you connect the power cord,
always identify the polarity symbol on its wires.
The power supply removing procedures are the same for the HPE FlexFabric 5930 switches. This
section uses the HPE 5930-32 QSFP+/HPE 5930-32 QSFP+ TAA switch as an example:
To remove a power supply:
1.
Wear an ESD wrist strap 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
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
4.
Supporting the power supply bottom with one hand, slowly pull the power supply out with the
other hand.

Put away the removed power supply in an antistatic bag for future use.
