WARNING!
• Never force open a locking ejector latch. The locking mechanism must be
disengaged to release the latch or damage to the latch could occur.
• Do not remove an AMC, CPM, or RTM before its hot-swap LED turns solid blue.
Removing it prematurely can cause unpredictable results in other parts of the
system.

WARNING!Be careful not to touch any heatsinks when removing the AMC, RTM, or
CPM because they might be hot to the touch. If possible, wait 3 to 5 minutes after the
hot-swap LED turns solid blue to give the air flow in the system time to cool the board.
