Notes:
1. The Ethernet Communication LED is always off unless the CE or the customer is connected to the
Ethernet port at the front of the enclosure.
2. The Information LED is not lit. However, even if it is, it is not a cause to replace the drive. If it is on,
the fan is probably running at full speed.
