LED Indicator
The Maxelerate can be self-powered, or bus-powered via FireWire cable. If the Maxelerate is connected as a
FireWire hard drive, sufficient power will be provided for hard drive and repeater functions, and the LED indicator will
be “on”. The amount of bus power supplied by the host, however, may not be sufficient for devices connected to the
repeater portion of the Maxelerate. Many devices draw more power and require the use of an AC adapter.
Additionally, when connected to some hosts, the LED indicator may be on when both host and Maxelerate are
powered off, but still connected to the host via FireWire, if the host is designed to supply power initiatively.
The following table details the status of the LED indicator under various operating scenarios.

functionalities are supported and the Maxelerate acts as a FireWire hard drive.

The Maxelerate can be self-powered, or bus-powered via the FireWire cable. If both USB and FireWire cables
connect the Maxelerate to the host, sufficient power will be provided for the hard drive, FireWire repeater and USB
hub, and the LED indicator will be “on”. The amount of bus power supplied by the host, however, may not be
sufficient for devices connected to the hub and/or repeater portion of the Maxelerate. Many devices draw more
power and require the use of an AC adapter. Additionally, when connected to some hosts, the LED indicator may be
on when the host and Maxelerate are powered off, but still connected to the host via the USB and FireWire cables.
