Installing and removing power supplies

CAUTION:
Provide a circuit breaker for each power supply and make sure the circuit breaker is off before
installation.
This section applies only to the switch models that support removable power supplies.
The HPE 5140 24G SFP w/8G Combo 4SFP+ EI switches each provide two power supply slots.
They come with power supply slot 1 empty and power supply slot 2 installed with a filler panel. You
can install one power supply, or two power supplies for redundancy. For information about power
supplies available for the HPE 5140 24G SFP w/8G Combo 4SFP+ EI switches, see removable
components in Hardware Information and Specifications.
When two power supplies are installed, you can hot-swap a power supply. To avoid device damage
and bodily injury, follow the procedures in
supply.
