G620 Switch Hardware Installation Guide
CAUTION
The power supply switch must be in the off position when you insert the power supply into the chassis. Damage
to the switch can result if a live power supply is installed.
NOTE
The new power supply and fan assembly must have the same part number and airflow label (or lack thereof) as
the power supply and fan assembly already installed.
1. To leave the device in service while installing a power supply and fan assembly, verify that the other power supply and
fan assembly (the one already installed) has been powered on for at least four seconds and has a steady green LED.
2. Using a Phillips screwdriver, unscrew the captive screw of the filler panel that is located in the empty power supply and
fan assembly slot.
3. Orient the new power supply and fan assembly with the captive screw on the right, as shown in the following figure.
Do not force the installation. If the power supply and fan assembly do not slide in easily, ensure that it is correctly
oriented before continuing.
CAUTION
Carefully follow the mechanical guides on each side of the power supply slot and make sure that the power
supply is properly inserted in the guides. Never insert the power supply upside down.
