The DC power supply replacement steps are:
1. Disconnect the DC power.
2. Disconnect the earth ground.
3. Remove the installed power supply from the power supply slot.
4. Install the new power supply in the power supply slot in the back of
the Switch.
5. Reconnect the earth ground.

7. Verify that the power supply is installed correctly.
Disconnect power from the source before connecting power to
the product or before accessing the product's power terminals.
The DC source can supply high levels of current capable of
causing serious burns and arcing that can produce molten metal.
Disconnect DC power from the power supply BEFORE installing or
removing the supply. Not disconnecting the power first can damage the
power supply or switch. Read this manual for proper handling
procedures.
To avoid power supply or switch damage, do not attempt to power-up the
power supply outside the switch chassis. The power supply requires a
load and other enabling signals to operate properly.
