NOTE
The HOT SWAP blue LED does not exist in first generation PIUs.
CAUTION
When replacing a PIU, disconnect power from the PIU module before inserting/ejecting it to/from
the chassis. If the PIU is with HOT SWAP LED, click on the handles and wait for the HOT SWAP
LED to turn on before disconnecting the power. After power is disconnected,disconnect the power
cable to avoid irreversible damage due to potential excessively high transient current. Connect
power to the PIU only after it is fully inserted into the chassis.
