Removing A Power Supply - H3C S9825 Series Manual

Figure2-31 Installing a power supply

Removing a power supply

CAUTION:
• When the S9855-48CD8D or S9855-48CD8D switch has two power supplies operating 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 present, removing the power supply causes power down of
the switch.
• When the S9825-64D switch has power supplies operating in 2+1 or 2+2 redundancy mode,
removing one or two power supplies does not affect the operation of the switch. When the switch
has only two power supplies present, removing power supply might cause power down of the
switch or power insufficiency.
The power supply removal procedure is the same for the switches. The S9855-48CD8D switch is
used as an example in the following figures.
To remove a power supply:
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 supply.
3. As shown in Figure2-32, use one hand to hold the power supply handle, press the latch towards
the handle, and then pull the power supply part way out of the slot. Supporting the power supply
with the other hand, pull it completely out of the slot.
4. Put the removed power supply in an antistatic bag for future use.
5. If you are not to install a new power supply, install a filler panel in the slot to ensure good
ventilation in the switch.
